himself is not listed as a licensed contractor or as associated with company. Received 20 day
notice from concrete supplier even though contractor had been paid. Apparently Donnys excuse was because we were holding last $1000 final payment for them to repair street. They charged extra for backfilling sewer trench. Charged extra for "placing" concrete in driveway trench patch, after quoting concrete price....only cost of material. Nickel and dimed at every opportunity. Poured double door too narrow for standard door, so our only option was a custom door. Was not following plans. Now several months after pouring floor is full of cracks. The cracks have cracks. Also damaged street with tractor bucket while changing tire, putting our street damage deposit in jeopardy. Nightmare dealing with this contractor. Buyer beware of lowest bidder.

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


We are very pleased with the job. Mr.
Concord Concrete Contractors Provider Name Locked
was responsive to our needs and was able to do our job with the little lead time we were able to give him. This was important to us because our basement and garage floor was ripped up because our drain pipes had been replaced. On top of this, the concrete in the garage was about ten inches thick. His employees are very good and have been working with him for years. The new floor looks great and I would definitely hire him again.

because of the great reviews I read here on Angie's List.
Concord Concrete Contractors Provider Name Locked
picked up and right away we set up an appointment. He came over and gave me a price which I thought was kind of high but when I got other quotes, I realized it was a very good price and when you add in the great quality of work they do from the reviews we decided to go with

. I called him back and he came over, we did the contract and I gave

the deposit and asked him if he could do the work in like a week and he said yes depending on the weather. Thank you
Concord Concrete Contractors Provider Name Locked
, the Lord sent the hurricane deep into the Atlantic and the weather cleared up in time for them to do the work when it was forcast to be raining all week. Praise God, He is good. The team came over bright and early in the morning and had the work knocked out by early afternoon. They addressed all my concerns professionally and kindly. The team was great to work with. I would definately hire them again. They did a super job. Thanks

used a concrete saw not a grinder to make a smooth finished (even) cut. He was very personable and professional. He arrived on time and finished in about an hour. Everything was cleaned up afterward.
- Scott C.

I had initially contacted
Concord Concrete Contractors Provider Name Locked
on Sep 9 to provide and estimate for the repair. I had an estimate on Sep 14. We agreed to terms on Sept 18th.
Concord Concrete Contractors Provider Name Locked
had let me know that it would be a couple of weeks before he could start. We met again on the 26th to go over the plan. He said at that point it would be approx 2 weeks to get started (now 3 weeks from our agreement date). I reached out on Oct 2 to get a start date. He promised me a firm date on Oct. 5. I haven't heard from him as of Oct 7 even after reaching out. I hear good things about his work which is one of the reasons I selected him but he needs to improve his responsiveness.
- Stephen B.

I originally left a voicemail expressing my interest in obtaining an estimate for some concrete work. Specifically a shed foundation and a small driveway extension (60 sqft).

When I received a phone call back, I was asked specific questions about the foundation type (monolithic vs other), whether I was building the shed or hiring someone else, on and on and on. I am an industrial project manager and understand the need for this information for detailed jobs of large scope and understand the needs for these requirements before beginning construction. But this information is not needed to provide a cost estimate.

I understand that their concern about the need for drawings for building permits and following the Florida Building Code. However, I was not given an opportunity to discuss my needs and my expectations. I was only told that "this company does not do this without drawings".

My issue is that not only was the woman who returned my call rude and consistently interrupted me, but she essentially did not want my business. I had every intention of having a site survey with fully engineered drawings for a building permit but I was not given any
Concord Concrete Contractors Provider Name Locked
to say so. Instead I was essentially told that they would not talk to me until I had those things.

You will notice that many of the other poor reviews on Angie's List with this company have to deal with how the customer was treated by the representative on the phone.

I urge the management to reevaluate their methods for dealing with phone calls as it's extremely off-putting.
- adam C.

The job was complicated because the existing apron was poured over another apron which increased the time allotted for removal and required the use of a jackhammer, which he had to drive back to his company to get (2 hours travel time, back and forth). By the time
Concord Concrete Contractors Provider Name Locked
and his assistant removed the old apron (which they hauled away) and built the form, it was too late to pour the concrete, so we had to delay a day. It rained the entire next day, so the concrete wasn't poured until the following day.
What started out as a 4-5 hour job, became at least double that, plus the additional trips. Though none of these problems were in any way caused by
Concord Concrete Contractors Provider Name Locked
, he completed the work without complaint and never asked for additional money from his original quote.
Concord Concrete Contractors Provider Name Locked
is a perfectionist and treated me as if I were his best friend. The work he did was much better than I anticipated.
I would not hesitate to recommend
Concord Concrete Contractors Provider Name Locked
and would never think about hiring any one else for this type of project. He is the best!!!!

The team at
Concord Concrete Contractors Provider Name Locked
&K did a fabulous job in our property. We are very happy with every single project they completed. It is not only that they are AMAZING masons but they are wonderful hands on people. They are very punctual and professional. They answered all the questions we had and were very open to any changes we had to make. They did a good job cleaning up after everything was finished. We would happily recommend them and they are our to go to masons for every project (big or small) we had or will have in the future.

Discovered there was no rebar in the original driveway, with some sections having 10" thick concrete. Also found no tree roots in the driveway, which was a pleasant surprise since there is a massive oak tree nearby. Mr.
Concord Concrete Contractors Provider Name Locked
(owner) came to my house the same day I called for an estimate, and the work was done the next morning. A large crew showed up so the excavation, rebar setting, pouring and finishing happened pretty quickly. Because of the large and deep cracks, dirt under the driveway had washed away, setting it up for a big collapse. The crew replaced the dirt before continuing. Mr.
Concord Concrete Contractors Provider Name Locked
was polite and professional, a delight to work with. I highly recommend his company and will use again if I have other projects.
