"The service turned out really good. My floor is sagging, and I have been looking for an engineer for that. I saw their ad, and I called them. The gentleman came, and he did a survey," and then he came with a date when the workers would come. The workers came on the day they were supposed to come, but what happened was, they put the holes in the wrong place. I came downstairs and told them where they were supposed to put them. They said they were sorry and they had made a mistake, so they filled up the holes that they had dug, and then they put the holes in the correct place, and then they put up the seal beams. Everything was fine, just that they weren't paying attention, and made the initial mistake. I would use them again, because I have another issue with the floors, because he said that we should wait a couple of years and see if it continues to sag, and now I need to get a full beam from back to front. I am going to do that next year. I should have put the beam from front to the back, and it would have solved the problem. The work that they did works perfectly, and I am happy with it, and I will do the steel beam from the front of the house to the back of the house which will solve the problem of the sagging floor. The gentleman who came out was very knowledgeable, he gave me plenty of suggestions, and the price was right. I was expecting to pay more, but I paid medium range from what I was expecting to pay. The only issue was that the workers did not look at the diagram correctly. When they come back again, I will tell them what they are supposed to do, and where the beam is supposed to go, so they don't make the same mistake again. It was a great experience, other than the small mistake, it was just a hiccup. He said he would get back to me in a year, to see if we needed the other beam, and I am going to get back to them this summer. I had heavy stuff in the living room, and the workers took it downstairs for me, so they went above and beyond the call of duty.

"I interviewed four structural engineers before selecting
.
was prompt, communicative and very professional. His services are very well" priced and the pricing is very straight forward. The price quoted is the price paid.
teamed up with the architectural firm to create the structural engineering design and permit plans for our new residence.
posed structural design questions from the beginning which aided the architectural firm in their design work. We had to meet a very tight deadline in order to submit our building permit with the county.
was able to fit the project into his very busy schedule and complete the work within the timeline that was given. I look forward to working with
through the construction of our project. I give
my highest recommendation.

came out on time quickly after the initial call. provided us with a report for the needed piers. he came out and inspected the installation of the pier as" well which i was pleased to have a third pary do this inspection. during this inspection he noticed some more problems in one corner of the house that was not noticed on initial inspection and recommended more piers in this area. 9 months later we are now having problems again with the foundation in the area which was only noticed on pier inspection. Emailed
to come out and take a look and he wanted his full fee to come back out to check on the property. Was not impressed by this response.

This can be maddening. Over the past 40+ years, in 4 houses, I have had or have run across this problem from gas meter leakage, water well pump column vibration, doorbell transformer, circulating pump, an extremely small (mist spray) water pipe leak, flourescent and sodium lights, security system horn dead battery, gas meter leaking slightly, bees in wall, bat colony, electric typewriter left on, stereo left on very low, and speaker inductive hum.

This seems to be a popular and recurrent question, so I am going to give the long answer for use by future questioners too.

I am assuming you do not hear this noise away from your house, or that other family members can hear it to. Obviously, if you hear it elsewhere also and other family members cannot hear it, then maybe you have tinninitus or are hearing your own high blood pressure blood flow (seriously). This commonly gets more acute at night when it is quiet, so all you are hearing is your internal ear sounds. I had this happen once because of a middle ear blockage - drove me crazy, getting up in the middle of the night because I thought I heard a water leak through the walls. Try putting on a pair of earmuffs or hearing protectors - if you still hear it or hear it louder, this is probably the case.

One method if hum is on the clearly audible side is make a 2 foot long cone out of paper to hold against your ear - like an antique hearing horn - then in each room face each of 4 directions while listening for where sound is the loudest, and turn your head to pinpoint the exact direction - I would spend 10 minutes doing this before getting into detailed stethoscope listening.

Otherwise, sounds like time for the old stethoscope (about $12 at a drug store - get a metal soundhead one, not cheap plastic, which does not pick up vibration as well). Also, if you are older (say over 35 or so) your hearing might have started to deteriorated with age, so if you have children or grandchildren with sharp hearing, they might be able to help track it down. I am sure a young child or grandchild, if you have one, would love this sort of treasure hunt (with appropriate "treasure" for a reward for tracking it down). 

Being careful not to come in contact with electricity with the stethoscope, check all the likely sources listed below. Start by placing it against pipes and walls and floor in each room of the house - water sourced noise goes a long ways, and tends to reverberate in the walls, so if that is the source likely to hear pretty easy. Hold stethoscope against bare pipes, both hot and cold, and heating system radiators or hot air vents.

If listening to water and hot water heating pipes indicates it is not water sourced, then you could turn off the master (outside) breaker or all the inside breakers and see if it goes away. I would only do this during above-freezing weather and early on a weekday, just in case a breaker fails to turn back on correctly when you switch it. Older master breakers particularly, which typically have never been used, sometimes break or fail to reclose properly after being shut off, so then have to be replaced. You want to be doing this at a time of day when, if necessary, you could get an electrician in the same day to replace it without paying weekend or nighttime emergency call rates.

If turning off the master breaker (or all other breakers) eliminates the hum, then turn them on one at a time until you find the one that turns the hum back on, then track where that circuit likely feeds (hopefully it is labelled) and check every switch, outlet, and light fixture.

Humming sources include (not in any particular order, a + in front means likely or common source of humming, - means rare or not likely):

1) + toilet fill valve - slightly leaking toilet inlet valve (listen where water tubing comes into toilet tank, and look inside tank to see if there is any water flow into or ripppling of the water in the tank or the bowl, or from the bowl filling tube (usually a small black plastic flexible tube which comes out of the fill valve (usually far left side of tank) and is clipped onto and discharges down into a hollow vertical brass or plastic tube or pipe in the toilet tank, which refills the toilet bowl after you flush)

2) + leaking faucet - kitchen, tub, shower, sink, utility tub, etc - it is amazing how just the smallest valve leak can make a hum or hiss that you can hear through the walls (especially at night), but only drips every few seconds.

3) - electric service meter dial motor

4) - electric breaker panel - rarely, a loose main power feed to a panel (especially with aluminum main service wire) will get loose enough that it vibrates back and forth and hums in its connector. A loose bus or snap-in breaker slot cover plate in the panel can also do this rarely

5) - gas meter or overpressure vent (unlikely, as you have had it replaced)

6) + boiling in the bottom of hot water heater or boiler because of buildup of lime, but would usually be intermittent - only when unit is heating

7) + furnace fan or electrostatic filter (forced air heat), or circulating pump (hot water baseboard heating), or steam condensate pump or overpressure venting (steam system).

8) - gas control valve or electric control box on a gas furnace, or its transformer (most have a 120V to 24, 16 or 12V transformer inside the front of the furnace

9) + air filter or electrostatic filter alarm on forced air furnace - some have a passive "whistle" opening that sounds softly when the filter is getting blocked, and if blocked with dust could make a hum rather than a whistle.

10) + Some water softener systems also have an "alarm" device to tell you it is time to service the unit, so check that if you have such a unit.

11) - a slightly leaking overpressure/overtemp valve on hot water heater or furnace (would be dripping)

12) - air venting from the air vents on hot water heating system. These will commonly make a hum or wheeze sound, for only for a few seconds at a time - not continuous unless leaking water

13) - city water system booster pump sound through the water column (if there is one near your home) - listen at the incoming water pipe - if much louder there than at other pipes within the house, that could be a house, though unlikely. If you think this could be it, find your water shutoff valve (typically 10' into your lawn from the street) and listen there. Would also be audible at neighbor's service pipe if that is the source.

14) - gas system compressor sound coming through gas pipe - listen to gas pipe outside the house and inside the house near furnace - if louder outside,, this could be a possible source, but the compressor or pressure reducer would have to be near your house. Would also be audible at neighbor's service pipe if that is the source.

15) + auxiliary booster circulating pump in your hot water or steam heating system (there may be one separate from the furnace, likely in the basement or a utility closet - most commonly found on  multi-unit apartment building with central heating and in 3 story or higher buildings, but you never know)

16) + a water leak, either inside or a leaking hose bib or pipe, or in your service pipe coming to the house

17) - electric on-demand water heater or electric-powered water filtration unit under the kitchen sink or inthe basement

18) + refrigerator compressor or fan hum

19) + doorbell transformer (front or back door - transformer is usually NOT at the doorbell, it is usually mounted in an open space like nailed to a basement joist, in an entry closet, or in the cubby space under the stairs - always physically near to the door, but NOT always on the same floor)

20) - any instant-on device like a TV

21) + any audio device (stereo, iPod, music player dock, computer, etc) that may have been left on at very low volume. Also, VERY rarely, if stereo or external speaker wires are run close to and parallel with an electric wire in the wall, they will acquire an  inductive voltage and hum.

22) + anything with a transformer, including stereo, add-on computer or iPod speakers, battery charger (rechargeable batteries or spare car battery or rider mower or boat battery charger), any portable electriconic device. Also portable device chargers (computer, iPod, cell phone, etc) - even if the device is not plugged into the transformer, as long as the transformer (charger) if plugged into an outlet, it is transforming high to low voltage, and transformers commonly hum

23) - electric typewriter left running

24) - electric ultrasonic cleaner or denture cleaner or electric toothbrush left on 

25) - home hair drying hood left on

26) - a lint buildup-jammed bathroom, kitchen, or attic fan. Many of these have, for safety, so called "self limiting" motors that if they jam just sit there and hum, but do not burn out.

27) - an attic cooling fan whose thermostat has failed, so is on all the time

28) - electronic furnace thermostat

29) + air conditioning unit, or aquxiliary air conditioner evaporator

30) + humidifier / dehumidifier - either permanently installed or portable

31) + portable heater / fan / air purifier

32) - automatic animal feeder waterer - either water supply or electric, as applicable

33) - dishwasher motor runningcontinuously - not shutting down after end of cycle

34) - convective or direct-vent oven or cooktop exhaust fan not shutting off

35) + flourescent (tube or CFL) or sodium or halogen light bulb / ballast hum (either inside, outside front door fixtures, or public street lights). These can hum quite pesistently when the starter circuit sticks on, or the bulb is dying and will not start (light completely), so the started circuit tries continually to start the lamp - can make a hum audible up to a block away on street lights.

36) - a dying electronic photocell designed to turn on your outside lights

37) - home security system, especially its alarm or horn. If the alarm is sounding but for some reason the main power is not getting to it, then as the battery goes dead (or if full voltage is not getting to it) is can give off a squeek, hum, or rasping sound - ditto if insects like wasps or hornets build a nest in it, so it cannot sound correctly.

38) + well pump, pressure tank, or filtration system, if you are on a well

39) + insect or bat nest in the attic or walls or in outside bins or cupboards, electric panel/meter, or outside telephone connection box (bees /wasps / hornets most likely) - though this usually varies by time of day, although it would "pulse" at the time of day when they are waking up or going to sleep.

40) + carpenter ants or termites - their continuous chewing of the wood can sound like a hum till you get right up against the colony, then you can actually hear the chewing

41) - a regional hum, as has been occurring at times in Ohio, Wisconsin, and Arkansas - where micro-seismic activity causes a hum or booming sound. Google or call your local paper and see if anyone has been reporting this in your area.

42) + outdoor power service transformer - either a metal (typically army green or gray) about 1 foot diameter "can" mounted on a power pole if you have overhead service, or a 2-3 foot cubic metal box on the ground or in a manhole pit near the street if you have underground service, which usually serves 4-6 houses (so may be in a neighbor's yard) and will have a voltage rating marked on it, usually in yellow stick-on lettering - like 4160V - 220V. Usually has high voltage - keep away safety markings on it.

43) - you have found where the Caddyshack gopher (who hummed to himself) moved to after Bill Murray blew up his happy home at the golf course.

Hope this list helps you (and future users with the same question).

There is NO such thing as an average cost !

 

You are going to be required to have a building permit and the Building Comissioner

or Senior Permit Official of your local permit office will issue a determination as to whether you will be required to have a Steel Bearing Beam , a Laminated Bearing Beam or some other Beam to support weight of the structure you want to ammend . You  may also be required to install Bearing support posts footings,  at either end of the beam as well. Much will depend as to what is over  and under the space that you wish to span .The official may require you to retain an Architectual Engineer to perform a Load study and computations and require you to  comply with his recomendations .

 

 Until you know what is required by the Permitting Office , Then and only then will you be able to determine the true costs .

 

The fact that you have existing baseboard heat , and we know NOT if it is electric or radiant baseboard heat will complicate the issue as well the existing electrical outlets which may need to be sunken into the floor in order to maintain the electrical circuitry as it exists.

 

 Past experience in these matters , indicate possible costs to range from  $4000.00 to  as much as  $8k -$10,000.00 . I realise that these cost ranges are probably NOT what you want or expect , but There are too many unknowns to attempt a closer cost expectation or range of expenses !

?

Architect first - for around $1000 typically you will get site consultation, a few sketches showing what you said you wanted, and a preliminary (by the book) cost estimate - that you can use to figure if your budget or scope of work needs major adjustment. Then, if you go ahead, typically about 10-20% of total project cost for complete plans and specs (including above cost), depending on complexity and level of interior design detail, and if construction inspection services are included.

 


 
 
Generally, nothing is free with an architect - unlike a contractor where a bit of consultation and a rough estimate is a lead-in to the actual work he hopes to get (the construction/repair) and part of his bidding cost, an architect (and engineer) makes his living giving advice and consultation and developing designs and cost estimates - so giving it away for free is sort of like a dentist doing sample fillings for free. Some will come to your house to discuss your concepts for 15-20 minutes for free, basically to see if they want to take you on as a client or feel your job is the type or size they want, but you should expect little or nothing in the way of a design or cost estimate for free - the most you might get would be an opinion on whether it sounds, off the cuff, like your budget is roughly in line with your desired scope of the project.
 
 
On more complex or up-scale remodels, it is not unusual to contact several architecture firms and request proposals - where they basically come see the site, then give you a sketch or few or more common today, computer-generated altered photos of your place, showing conceptually what they can do for you, then you choose the one you like the most and go with that one for final design. Typically $500-1000 range fee (each) to get that done for small jobs, larger jobs will typically be no charge but that assumes probably $25-50,000 plus anticipated fees if they get the job.
 
 
Bear in mind in the latter scenario you cannot pick and choose betweenthe best parts of each proposal - the architect owns the design and it is copyrighted, so while you can choose bui9lding elements (dormers, bay windows, etc) from any of the proposals, specific design or color combinations are copyrighted by the proposer.
The Search the List category is Architects and Building Design.

The key is to have drainage away from the house, and not introduce water to the foundation unnecessarily. If you can slope the existing backfill soil from the foundation away from the house at least 1/2 inch to 1 inch in the 2 foot space to the walk and pack it down, then putting a ground cover on it will not hurt - it is the relatively impervious layer sloping away from the house you want. If you use rocks I would underlay them with some 6 mil or thicker black plastic sheeting (available in small rolls at home supply stores and lumber yards). If planting, the same would be nice if the plants you choose spread laterally like Epimedium, so they will grow in just a fewe inches of topsoil over the plastic. Otherwise, tamp down the dirt to make it a hard, draining surface (at least when it rains heavily) before topsoiling and planting. Keep a slope on the topsoil too, and avoid overwatering. Do not plant anythig with highly invasive, tenacious or deep burrowing roots like bushes, ivy, or trees near the house, as the roots will penetrate the waterproof barrier on the outside of the foundation, and then you might start getting leaks. The roots can even penetrate the concrete block joints and start breaking up the foundation. For this reason, annual flowers, shallow-root ground covers, bulb plants and rock gardens are far better within 3 feet or so of the foundation than larger plants or intensive gardening.

He was very good, knowledgeable and prompt. He came out the next day after we called. He indicated there wasn't a problem at all. He also provided a very thorough report in his inspection that included pictures and had blueprints of the designs to show that the trusses were per the initial contractor specifications. The home inspector just didn't inspect througly enough.

, you did an evaluation and report for me back in February, 2013 before I purchased this house at the below mentioned address. Now I may need your assistance again depending upon the cost.







I will be adding a small room enclosure under one section of my covered back porch. See attached sketch.







The City of Southlake wants to be certain that the foundation area under the exterior porch wall will support an enclosed wall with a brick exterior tied to the new walls. See photo #4. They want a document from an engineer saying it will be okay to proceed with the plan.







I also have another small issue with a slight dip or valley in the floor of my master bath. I need to find out if it might be an issue to be concerned about.

returned my call promptly. He described what service he would provide for the structural inspection and what his fee would be: $350. The inspection date was set. He arrived promptly and got right to work. He answered all of my questions and gave me his opinion of the basement wall crack. We had previously filled the crack and needed to know if anything further would be required for the wall to be structurally sound. Good news! It was a common settlement crack for the age of the house with no bowing and no leakage. Nothing further would need to be done.

was absolutely amazing. He is a Rock Star of structural engineers, and I would recommend him to anyone who needs a true expert. He did not just use mathematical formulas to make a decision. He was up on ladders, taking pictures, measuring actual deflection of the trusses and so forth. The recorded everything he saw with pictures and audio to remind himself of exactly what he took the picture of & provided a detailed report that left the other engineer with no room to argue. It was fantastic to witness.
He completely proved the builders engineer wrong; and showed exactly why & what was out of compliance with building code. The builder's engineer tried to get out of it the cheaper way, and not do as much work as
New York Structural Engineers Provider Name Locked
recommended, and ended up having to redo it all the way
New York Structural Engineers Provider Name Locked
stated in the report. This was due to the way
New York Structural Engineers Provider Name Locked
examined the ACTUAL construction, and not just what was in the computer.
It ended up that the trusses that were called for in the blueprints were actually manufactured incorrectly. So without physically inspecting the trusses themselves, there was no way to understand the TRUTH behind why the floor was sloping under zero load.
To add icing to the cake, he inspected more than what he was hired for, and also found another problem with my house that was completely missed by the builder and the county inspector!
