"The entire job went great.
started when they said they would, and completed the work in just a few days. They even worked a Saturday and" stayed late to finish one night.
was prompt to return phone calls and answer questions. Everything went perfectly. We are very happy with our new patio.

-Aaron K.

and his crew did a great job. The demo was much more difficult because the patio was thicker then we all expected.
" and his crew worked a long day to get it done. The new concrete looks really great. They cleaned up the worksite really well, too! I highly recommend them!

Concrete Repair: How to Avoid Common Scams

Hiring the right concrete driveway contractor will help you avoid being taken advantage of.

Bids are NOT done based on a multiplier on top of materials cost to get labor cost. Think of the consequences in the example you gave - by that method using say plain home depot tile made in Honduras might cost $5/SF materials, so by your method $10 labor. Now, same floor, with Carerra marble or Barre Granite at $75-100/SF - so do you want him charging you $150-200/SF labor when it takes almost exactly the same time regardless of material ?

To put it in simple terms, contractors:

1) figure the amount and cost of materials and consumables needed from the plans and specifications, applying a markup (from 15-50%, depending on contractor and how fancy or specialized a job it is).

2) Then they figure the equipment needed and the operating time to be used or elapsed time to be rented or leased - either opperating hour or elapsed time, or combination of both, especially if it consumes fuel

3) They then figure the labor time for the various trades required to do the job, maybe add an efficiency or ease of work multiplier to those hours to fit the job conditions, multiply those hours by the hourly pay rates, then multiply that times the "load" or "Labor Overhead" to account for employment taxes, workman's compensation costs, health plan, etc, etc.

4) Then they add in the cost of any architect or engineer plans or certifications that are needed, government permits and inspections, etc.

5) Then they add in any subcontractor bids, with appropriate contingency amount for each.

6) All those above totals are added up, an appropriate overall contingency added if needed (typically 5-10%, but on remote site jobs I have seen as high as 200%), and (depending on how contractor figures his costs) at least all the "in-house" costs like his equipment, consumables, and labor costs have a percentage overhead and profit added to them - typically about 100-150%. Some contractors use a lower overhead percentage but apply it to the total estimated job cost, not just in-house costs.

This "company overhead" or "general overhead" or "G&A - General and Administrative Overhead" covers the costs of financing and running the company, management and secretarial and general supply and maintenance costs, buildings and equipment yards lease or mortgage cost, working capital cost, insurance, loan interest, general shop equipment payments, profit, etc. Some contractors use a lower overhead and apply it to every cost in the job, some (especially those doing government work so havingto adhere to government accounting rules) apply a "markup percentage" to materials and rental costs and outside subcontract services, and apply G&A overhead only to in-house costs.


That being said, for a general class of work it does generally (on normal jobs) work out that there is a general multiple of labor to materials cost. For instance, yard work and residential tree work is heavy on labor, so it might have a labor to materials ratio of 3:1 or even 5:1.  Detail foundation hand excavation and underpinning can run to 5:1 or more. Many types of building construction like plumbing, tile, carpentry, etc. do end up with a very roughly 2:1 or 3:1 ratio of labor to materials cost. At the other extreme, high energy efficiency or hurricane rated glass installation or a fancy full-building computer and communications system or high-end entertainment center might have a labor to materials ratio of 0.25-0.5 because it is designed to go in pretty fast, but the materials cost a lot.

For your case, a hardscaping ratio could run from 0.5:1 or less to as much as 3:1 or more, for installations with very expensive imported stone and fancy woods and a lot of bought decorative items such as statuary, to the opposite labor-intensive landscaping with lots of sidehill terracing and hand-planted flower beds, hand-dug irrigation system trenches, and manual-placed concrete block or railroad tie walls. Each job should be figured on its own merits - using a "rule-of-thumb" is where people commonly get unpleasantly surprised. That is why you typically get 3 bids unless you have a contractor you trust from prior experience and are confident will give you a fair shake regardless of being sole-sourced. Personally, both for my own purposes and professionally in the design and construction business, I have found sole-source to trusted contractors you have experience with is, in the long run, a BIG money and time saver, as well as making it far more likely to finish on schedule and let you sleep at night.


You need a general contractor - prefereably one who specializes in additions, because you have excavation, waterproofing, concrete, concrete cutting, carpentry, door and window, etc trades to coordinate.

The cost will depend a great deal on your topography around the house - if the base of the window will be above ground level at least 6 inches, then could run about $500 for a legal egress window purchase and about $1000-2000 for installation, depending on how deep into the concrete you have to cut.

If the bottom of the window will be below ground level, then to call it a bedroom (which mandates legal sized second egress and usauully at least one window)  then you will have two choices - bring it out into a solid watertight concrete storm cellar with collar to keep water out, stairs, and and weather and bug-tight cellar door that is inward-opening, which means a lot of space for stairs and landings top and bottom, or bring it out into an oversized window well at least 36 inches in diameter, and with steps to ground level, with adequate drainage and waterproofing to keep it dry. Either way, sometimes about as easy to put in an outside door as a window, and might raise property value more. Cost from $2-5,000 depending on how deep into concrete wall you have to dig, whether concrete wsall needs reinforcing with steel frame because of the depth of cut, how easy the digging is, and what your water conditions are near the foundation. The last thing you want to do is create an easy water or vermin ingress with your egress.


The cost to install the veneer stone has a wide range do to many factors. It can range from around $9 to $17 per square foot. It depends on the location, the stone being used, job access, skaffolding needs, wall prep and such. I would think you would be on the lower end of the scale. Your job is on a concrete surface so it eliminates one of the biggest problems they are having with this product, wall preperation. This one of the things that separates the high bidders from the low ones. There are million dollars homes being torn down because of improper wall prep. One a wood frame house a backing system that allows drainage is a must or the moisture absorbed by the veneer can rot the walls behind with alarming speed. Some have had makor damage within the first four years. On a concrete wall the veneer needs no such prep at most wire mesh applied if it is an older concrete wall.



Concrete Repair reviews in Concord


He told me he would look at the driveway and give me an estimate to repair. He never responded back and never provided an estimate. Inquired about estimate status and he never responded. We had a timing issue do to a real estate sale, which was stated to him and he never provided an indication that he could not accommodate a quick turn around.

was very professional and his bid was great! We had several other concrete businesses around
town look at our crumbling concrete and they would not even give us a bid. They did not want to touch the job.
Concord Concrete Contractors Provider Name Locked
crew came in and broke up all the concrete in one day. They removed it the following day and the next day they were prepping for pouring the next day. They had to pour around all our
Concord Concrete Contractors Provider Name Locked
and planting beds and they also laid down wire mesh and
rebar and pipes my husband wanted so he could run electrical under the new concrete and put lights all around the yard.
The new concrete looks amazing and is such an improvement.
They were on time and very professional.
They were a great choice. We would use them again or recommend them to anyone.

was quick to respond to my request for an estimate of work and scheduled within a few days. He was always on time for appointments and scheduled work even though he had to drive to the northern suburbs in rush hour traffic. His charges for services are very reasonable. I would recommend

to friends and family.
I do want to add that there was an issue with the work that was first delivered on my front walk stairway (reason for quality of work B).
Concord Concrete Contractors Provider Name Locked
owned the issue and asked what he needed to do to make it right. I decided that tearing out and redoing the stair was the needed solution.
Concord Concrete Contractors Provider Name Locked
owned the issue and agreed without hesitation to the redo. He scheduled it within a few days and again returned on time and did the rework himself. I respect that he owned the error and was respectful through the redo process and delivered good work with the rework.
- DiAnn H.

The job had to be postponed twice due to rain, but it rains daily here. The job was done to my specifications for shape and slope. The crew arrived on the next partially dry day, completed the job, and, they cleaned up after themselves!
- cynthia B.

I called several contractors for this job, but only few returned my call. JP
Concord Concrete Contractors Provider Name Locked
was one of the contractors that returned my call on the same day and answered all my questions. They sent me an estimate over email. I had several other questions which I communicated over email. They responded to all my questions and they were able to do the job that same week. They came on time and finished the job well. The manager came out and check the quality of the work that afternoon. I really appreciated how promptly they communicated everything.
- Jin K.

The entire project went extremely well. They first started by demolishing our old deck in a very quick amount of time. Followed by all the necessary steps for the patio. We worked closely with
Concord Concrete Contractors Provider Name Locked
who helped with the design and explained all the steps that they were going to follow and in the process. He was extremely patient and offered ideas and advice for the design of the patio and steps. The entire company including the office staff was very friendly, answered all of our numerous questions and were responsive to keep us informed of the start date. Given all the rain we had this summer, our start date was pushed back a number of times but we were always informed of a new possible start date. The Gcat crew worked extremely efficiently and cleanly in the entire process. We are very happy with the finished product and would recommend Gcat to anyone who is looking for a new patio, driveway, etc. I will use them again if the need arises.
- Owen B.

It went great at first.
Concord Concrete Contractors Provider Name Locked
was very prompt, brought samples, and gladly took a check for 50% of the job. Several calls asking when his son was going to complete the sample and no response. One week before
Concord Concrete Contractors Provider Name Locked
was to start,
Concord Concrete Contractors Provider Name Locked
stopped by on a Sunday morning with a refund check in hand. He explained they were moving to
Concord Concrete Contractors Provider Name Locked
No other explanation than that.

A couple of points The delays forced other projects to be delayed. A sizable amount of money was taken from a savings account actually getting interest. And....you really should wonder why a firm does not want to get involved when a portion of the job which required a permit. I was shocked when I opened up Angie's list to see
Concord Concrete Contractors Provider Name Locked
is offering a deal. I wonder if it is a moving offer?
- Michael G.

I thought these guys were excellent. They showed up on time and took their time to do the job right. I would certainly use them again. Excellent workmanship. Big thumbs up!
