We invite you to schedule a meeting and consulting with one of our expert for free!

"DONT WASTE YOUR TIME! We were contacted by Avi after using Angi's List. He said he was in the area and could swing by for an estimate. Once here he suggested we get the leak from our skylight fixed immediately. We agreed, signed a contract then paid a deposit. Work was to start the next day. We then get a call, parts won't be in for four days, but crew will load up and be here Monday with the parts. Monday comes around, no crew. I call late morning and am assured crew will be there. They show up with caulk. I call Avi, he explains they don't have the parts, and don't know when they will, he comes down and tarps the leak. He offers to pay for a new skylight if I don't leave a bad review. I tell him just fix the leak as agreed. One week goes by, he texts me they can't fix it and offer to refund me. What a waste of two weeks! At least I got a tarp out of the deal. What roofing company can't fix a leak from a skylight? I have a complete text log from with all the excuses to why they can't do this job for all those future customers to enjoy. It does make for a good laugh at the back pedaling from Avi."

Concrete Leveling questions, answered by experts

Sealing the concrete before tiling is recommended to help it stand up against any water that may seep through the tiles or grout. After thoroughly cleaning the concrete with TSP, priming with a concrete primer will seal the concrete. Check the label on the primer to make sure it is also a sealant and follow the manufacturer’s instructions for application.

Clean with a damp mop and reseal every few years to protect the surface and enhance appearance.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Placing either a layer of mixed-size gravel or a paver base under your crushed concrete driveway is a good idea. The smaller pieces will compress and prevent the larger pieces of concrete from driving into the soil below, helping to avoid sinking over time under the weight of vehicles. For added protection from sinking and weeks, you can also install a heavy-duty weed liner beneath the gravel or paver base. Just be sure to use a permeable material to avoid drainage problems.

There isn't a winner when comparing expanding foam versus concrete for fence posts. Both have benefits and drawbacks, depending on your budget and priorities. Expanding foam may be a better choice if you want a more eco-friendly solution that cures faster. Concrete is more affordable and durable than expanding foam, yet it is harder to work with and takes longer to cure.
