"He was quick to come out and help give me an idea of how bad the foundation crack were. He explained what needed to be done in a way that was easy to understand" but not patronizing, and then he sent me an estimate very quickly.

"We hired
based on a recommendation from our landscaper and we are glad we did. He arrived on time and got right to work. After a few hours" of grading our yard we were left with a big pile of shrubs, bark dust and general yard debris. After seeing the pile and realizing I am lazy, I talked with
about getting a dumpster and a dingo to dispose of everything. He set up both the dumpster and dingo rental and by the end of the next day had everything loaded into the dumpster and the yard completely graded.

Angie's Answers

Mold in a basement is a common problem. My company helps people with this every day. Some of the answers you received were helpful but not all the information is correct. First, you need to eliminate the two main ingrediants that mold needs to survive. The first one is water intrusion. This is a must. I am assuming you have no water intrusion as you make no mention. The second componant that needs to be eliminated is moisture. Moisture is also humidity. Basements need to be kept airtight in the summer months. Some folks have posted that you need air flow in your basement. Nothing could be furthur from the truth. When you open any windows for example, not one micron of air goes out of the basement, Warm humid air is sucked into the basement. Houses suck air into the basement and it meets the cool surfaces and skyrockets humidity. The windows must be kept closed and a dehumidification device installed to ensure humidity stays below 60% humidity. The dehumidifier should be energy star rated and purchasing a seperate humidity guage is a must to monitor the unit's progress. We like to keep our customer's basements at 50% humidity. This eliminates the smell that is active mold spore growth. Once the water and humidity is brought under control. Remove the organic materials that have mold on them. Walls, sheetrock and studs that have been affected. Follow the advice of previous posts as you must ensure that you do not affect the rest of the home. Once removed, install new walls using as much inorganic material as possible. We also install vapor barrier over the walls and seal the floors to stopwater vapor transmission into the basement. Poly plastic is not a acceptable vapor barrier. It is not "zero-perm" and will still allow moisture transmission. It will also crack and break into pieces over the years. A PVC liner rated "zero-perm" is the correct product in this application. Depending how large the basement is and if it is sectioned off will determine the dehumidifier strength. We use the Santa Fe line of dehidifiers as they are super energy efficiant and work like a dehumidifier on steriods. I hope this helps and I wish you the best in Basement Health!
?

Where is the home located, what is the exterior wall construction and type, how is the space heated?

 

It could be a whole host of different scenarios that would generate that result.  It is nearly impossible to tell but I would say that most basement moisture problems are a result of bulk moisture intrusion or condensation issues. 

 

Given the deep and hard winter this year, it could be a condensation issue that hadn't previously been shown.

This is a family business. All members I spoke to were courteous, timely and professional. They did what they said they would do even before I expected them to begin. Cleaned up area leaving it better than they found it. I would recommend them.

It's nice when you meet a contractor whose primary concern is not "selling you" something.
Portland Waterproofing Contractors Provider Name Locked
was amazingly honest and forthright, advising us not to do the work we had considered because, as he pointed out, our basement walls had been painted and the hydraulic cement they use to parge would not stick to the paint. In short, it would have been cost prohibitive for them to remove all the paint in order to prep the walls to do the job right.
We really appreciated

's honesty, as a less-than-quality job most likely would have failed at some point down the road. Since the walls are in pretty good shape and really just need to be cleaned and repainted, he gave us a "DIY "suggestion, which will save us a lot money and work for what we need.
Would highly recommend

I called to get an inspection of my crawl space, I was concerned about some water when we had the heavy rains in Feb.
The inspector came out and did an extensive inspection. He told me that someday I would have to have the vapor

First of all, let me say I have held off writing this review until we had time to experience serious rainstorms and how the proposed solution worked. The work was done in February, it is now April. we've had a problem with wet carpet/water in one corner of our daylight basement for a number of years, and each year it got a little worse. It seemed no amount of caulking on the exterior concrete and where it met the wall made any difference. This year the wet areas went farther than before, and extended along the adjoining siding door to the outside. This year it was obvious the problem was getting worse, so we called for an estimate from

was on time and didn't waste any time analyzing the problem; he said our problem wasn't surface water, but ground water coming up under the concrete patio. Eventually it finds a way between the concrete pad and the wall foundation, and then it soaks the carpet. He indicated the solution was a trench dug under the interior concrete floor perpendicular to the wall, with a sump pump at the end pumping it outside to the downspout. As a caution, he suggested a similar treatment to the adjoining wall, since the conditions were similar and there was considerable cost avoidance as opposed to having to come back. We scheduled it; they were in/out in two days (the concrete needed to set overnight). They carefully folded the carpet back to be out of the way, and even tested the downspouts to ensure the drain fields were working. The concrete cutting was subcontracted, but Masonry handled everything else.

emphasized they would clean everything up, and they really did...aside from the carpet lying a little differently at the edges, you'd never know they'd been here. Considering the dirt and water, it was quite a feat. The only complaint I have is that I wish
Portland Waterproofing Contractors Provider Name Locked
had been clearer about how the sump pump piping would go through the wall to the outside downspout. It's a good solution, but the outside concrete level is higher than the inside floor level, so it was necessary to exit the wall higher than we realized was necessary when we started. It is as much my responsibility to ask those questions as it is the contractor's. In hindsight I would of considered paying more to dig out the outside concrete and hook up the piping below outside ground level so it would be lower on the inside wall, even below the floor level. The bottom line....we've had 3 or 4 soaking rains over multiple days in the past 6 weeks...and it was dry as a bone in the basement every time. And we never hear the sump pump.

These guys were great.
Portland Waterproofing Contractors Provider Name Locked
knows a lot about drainage and in initial interview told me many things I could do myself to keep water out of the basement. In addition to those tips I had them do above work. They were prompt, thorough, and efficient. I really feel like they did what they needed to do to do the job correctly. In addition to above they put a new fence post in for me and fixed an overhead leaking gutter. All above and beyond what they were there for.

Masonry Masters (

and crew) was very easy to work with, honest, and did an excellent job on both projects to prevent water from coming into our basement. Each leak required a different solution, but we have not had a drop of water in our basement since they worked on it. I would recommend them without hesitation.
