"From the minute they got out of the truck to check our project, to give us a bid we knew they were the company we would hire. They seemed to know what we wanted by way of design and finish, before we spoke. Where other companies had said flat out “We won’t do this.” “Too much work removing old concrete.” Poor access.” Moli said, “Yes, this old concrete gotta go. But, it’s no problem. We bust it up. We take it out.” At the end of the first day all of the old concrete had been removed and taken away. At the end of day two all the forms were set. Day three was rebar and detail work making all ready for the pour. Day four The concrete was poured stamped and finished. On day five everything was picked up cleaned up and they were gone. These are good people. They do good work and they are as honest as the day is long."

"I kind of questioned the cost after they did the job. What they actually did here looks pretty good. I just had surgery that time so I was in bed when they came out. They did it under 40 hours and did good work but they handed me another bill that was triple the price. The labor was okay but within that labor, they planted things for me. I had asked them to make it easy to maintain but they never discussed anything with me. I’m sure they upped the cost for the plants quite a bit. I don’t even know what plants they are. They did put in some bricks and they did a good job on that. I told them that I wanted some grooves leveled out in my yard and I realized afterwards that there were still some tracks in the yard. It was covered by grass but I pointed out where they were."

Basement Waterproofing FAQs, answered by experts

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.
