"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."
"After meeting and getting quotes from 6 other contractors we felt most confident and comfortable choosing Cretec Concrete. Spencer was very prompt meeting with us and delivered a quote the next business day. We knew aster discussing our needs his company would be the right fit. Our project consisted of a complete demolition of existing concrete patio, removal of grass and regrading the area to accommodate a new drainage channel. Our new patio is over 1400 square feet that is colored and stamped. It is exactly what we were looking for maybe even better than our expectations! Spencer and his crew were very friendly and professional. They completed the job in even less time than we anticipated. We would definitely hire Cretec Concrete for any future concrete needs"
"Two jobs completed at separate times; three days altogether for both. TerraFirma quickly completed both jobs and the basement environment is significantly improved. We immediately noticed a difference in the air quality in the basement. The crawl space looks great and is now a clean environment. The concrete patio is now even and water no longer flows towards the house foundation. Issues : Crawlspace - 1. The invoice I was presented at the completion of the job was $900 more than the agreed upon price. After an hour, and me needing to make several phone calls, the situation was resolved. 2. The dehumidifier was not placed in the designated position described by the salesperson and noted in the plans. The dehumidifier was to be placed in an open spot in our basement adjacent to our utility sink. The foreman on the day of installation said that was not standard, pointed out how it was not possible to place it in the basement and installed it in the crawl space. The foreman and I tried to contact the salesperson for clarification but we were not able to get ahold of him. The foreman said this was typical. The salesperson did call me back at the end of the day but by then decisions had been made and work completed. 3. The dehumidifier was placed in such a way that the programming screen is not visible from the crawl space opening. If the unit throws a code there is no way to tell other than entering the crawlspace. 4. The salesperson said we would be provided with “decorative screens” to cover the crawlspace openings in the basement. What we received was wire mesh glued on to the cement walls. 5. We needed to make further arrangements with an electrician to accommodate the unplanned crawlspace placement of the dehumidifier. Patio polylevel – One of the two-man service crew brought his family (friends?) onto my property and worksite without consulting me and entertained them in my backyard for about a half an hour, mid-afternoon. Besides being a serious liability issue, I have to say that it is one of the oddest things I’ve ever seen a service person do; and I’ve seen some odd stuff."
"Alan and his team are very hard workers and aim to please. They were friendly, arrived on time, did a good clean up and explained very well what to expect. What I have learned in concrete staining, especially concrete that had been covered in tile for 50+ yrs, is you can not predict what the concrete color will be, it is not like paint. I am very glad I choose a light color to stain with, as my floors then darkened up to a deep brown/grey/green/tan. I used the water based sealant and it gave more of a Matte finish even though the test sample was more shiny. So if you want a shiny finish go with the industrial sealer. We wanted just a bit more shine so Alan came back and fixed it with a product called Zep. It is perfect! Finishing the floors was not as toxic smelling as I thought it would be. ( My hard wood floor refinishing we had to leave the house for a few days.) Windows were left open for part of the day but closed at night and it was cold as we had freezing rain. The floors dried fast and we were able to walk on them in 24 hours or less. I would highly recommend Your Concrete Guy. He was the most reasonable offer we had and was flexible with my requests for additional work and sealant. "

Concrete Mudjacking questions, answered by experts
Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.
Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.
A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.
Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.
Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.
