"I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services."

"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

"I recently hired VanDrunen Outdoor Living to resurface my concrete walkway and stairs, and I am incredibly pleased with the results. The original concrete steps were caving in, and the walkway was in poor condition. After reaching out to VanDrunen Outdoor Living for an estimate, I had the pleasure of working with Zack VanDrunen, who was professional, courteous, and responsive throughout the entire process. Zack provided a detailed bid to replace the damaged concrete steps and resurface both the walkway and new steps using Vuba Stone. What impressed me most was his approach-there was no pushy sales pitch, just honest advice and clear communication. The finished product exceeded my expectations. The steps and walkway now look amazing, so much so that they almost outshine the rest of the house! The quality of work is exceptional, and I couldn't be happier with the outcome. I would absolutely recommend VanDrunen Outdoor Living for any concrete work. They demonstrated professionalism, skill, and commitment to customer satisfaction from start to finish."

Concrete Leveling questions, answered by experts

When pouring a new concrete slab, you should consider how additional costs will affect your total, including reinforcements, decorative enhancements, finishing, and curing. It's also important to consider local laws regarding the grade, drainage, and permits for installing concrete on your property. Speak with your professional about the ideal thickness for your slab, and also consider whether you’ll need drainage for slab longevity.

Pavers last longer than both concrete and asphalt when well cared for. Since you can place individual pavers that suffer damage, you won't need to repave the entire driveway for an average of up to 50 years. However, the best material for you comes down to your local climate and budget.

Yes, concrete changes color while curing, moving from a dark shade when wet to a lighter shade once dry and fully cured. Wait at least 10 days after pouring the concrete to gauge the color of the final concrete. If the concrete remains dark or discolored after that period, reach out to your concrete contractor with questions.

You can pour concrete over asphalt if it’s in good condition, thick, stable, and well-compacted. Concrete is more durable than asphalt and can extend the lifetime of your driveway without having to pay frequent asphalt driveway repair costs or replace it completely. 

But this is best reserved as a temporary solution based on budget restraints, as asphalt requires more frequent repairs and assessments than concrete. Once that concrete top is poured, it’ll be harder to accurately understand what’s happening beneath that layer, which could lead to more issues.

Unfortunately, concrete cracks happen, so there’s no surefire way to avoid them long-term. To slow down the cracking, apply a sealant every two to three years and use sand rather than salt to melt snow or ice. Using salt speeds up the freeze-thaw cycle, which may increase the likelihood of cracking. Additionally, keep vehicles and heavy machinery off of your concrete, as the weight can lead to more cracking.
