"Donald and Guiles came to complete a job at my home in Granby, MA in September 2026. They were extremely professional from start to finish. They arrived on time and took the time to thoroughly explain everything before beginning the project. Throughout the process, they kept me informed and made sure I understood what was happening every step of the way. They worked slowly, carefully, and thoughtfully to ensure the project was completed without causing any damage to my concrete slab. They also pitched my slab perfectly, which was very important to me. I truly appreciate the care, attention to detail, and professionalism they put into the entire job. I would highly recommend them!"

"Thrasher did an excellent job repairing our driveway. They leveled out the entire driveway with amazing precision, and they fixed all the gaps with an attractive sealant that blends beautifully with the concrete. All of the team members I interacted with were professional and polite. I am very pleased with the results and only wish I’d called them sooner."

"Dug holes in garage slab to connect plates from outside to inside with threaded rod and filled holes with concrete.  My task was to use large wrench they provided to tighten the nuts on the outside after concrete had time to set.  One wall was over 1/2 inch from slab before tightening and the other was over 1/4 inch.  After a few weeks I had the gap for both too small to measure.  Over 6 months later and all is well.  Very professional job."

"The sales guy was very impressive. He explained everything about the process and did a detailed inspection of the areas to be worked on.
He was honest in saying that sometimes the concrete seams don't match up perfectly, but that the installers would use a grinder to feather out any spots where this would happen. I asked about cracking and he said that it rarely occurred.
The installer came on the appointed day and was still there when I returned from work. He had completed much of the job, but indicated that he had trouble with some of the equipment and that some of the poly-leveling material had sprayed around some of the work areas. He said he would come back and finish the next day (which was a Saturday).
He returned Saturday and finished. I inspected the work and was generally happy with the concrete leveling; my front step was now very close to it's original height and my patio was shedding water away from the house. But I did find a couple of things that distressed me and told the installer about them:
1. There were two very noticeable cracks and a third very thin one. Would he be filling these cracks to prevent future water damage?
2. There were many places in the driveway where the slabs were still uneven. Was he planning on grinding those down as promised?
After he left, I also noticed that the patching material used to fill the holes seemed to be chipping away already and in several holes, did not even come up to the level of the slab.
He later called back and said that he would come back and use a high quality sealer to fill the cracks. He didn't mention the uneven concrete.
I later was contacted by the office about payment. I explained that there were outstanding issues. I was assured that arrangement had been made to fix them.
Then I made the ultimate error: I paid them.
When the sales guy made a follow up call, I told him there were still outstanding issues, and that I had been promised that they would be addressed.
No cracks have been filled, the holes collect water every time it rains and I am mortified at the prospect of trying to clear snow from my uneven driveway this winter.
Could I have made more noise with them about this? Sure. Should I have to after making three people aware of the problems? Certainly not."

FAQs for concrete work projects in Onawa, IA

Figuring out how many bars you need isn’t a one-size-fits-all equation. A structural engineer or experienced concrete contractor will look at your slab’s thickness, the loads it must carry, and local code requirements, then run the numbers for you. That quick consultation protects your budget and keeps the finished slab safe, level, and up to code.

Match the metal to the job. For light, thin pours like a sidewalk, welded wire mesh often does the trick. Thicker slabs—driveways, garage floors, foundations—usually call for traditional steel bars. If your site sees salt, humidity, or coastal spray, spend the extra cash on galvanized or stainless steel to fend off rust and avoid future repairs. When in doubt, a concrete pro can confirm the best fit for your project and budget.

Stainless steel costs more up front, but the alloy can last 75 years or longer with little to no rust. That longevity means fewer repairs, less maintenance, and peace of mind for structures exposed to salt, moisture, or de-icing chemicals. If you’re pouring near the coast or in a humid climate, the extra dollars now can save you multiple replacements down the road.

An engineer will review the slab’s thickness, span, soil conditions, and expected loads, then specify bar size, spacing, and grade. Skipping that step or guessing can leave you with cracked concrete or a blown budget. For a modest consultation fee, a local engineer or contractor can do the math and hand you a rebar schedule that meets code and keeps your project on solid footing.
