"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"I've worked with Donnie on several properties to evaluate structural issues, he's always been very professional and thorough with his inspections and identification of structural issues. Recently I had him perform a structural repair on one of my properties that had a tight deadline due to insurance and he got it done without an issue. I would recommend Donnie and Upstate Structural Repair for any structural repairs or consultation!"

"Ethical plumbing did a fantastic job on the customer service side and the repair side. Alisha, the rep who contacted me on a Friday evening almost immediately after starting my search was pleasant and efficient. She made it possible for me to get service the next day. Michael showed up as scheduled Saturday morning for what I thought was just going to be an estimate but to my surprise was able to complete the job that day! And this wasnâ t an easy undertaking. It Involved digging, cutting lines, valve replacement for a leak behind the city meter. These guys are the real deal! I thought the price was a bit higher than I thought it may be, but the value received made me comfortable with it. Same day service, done professionally. I wholeheartedly recommend Ethical plumbing.

"My dealings with Chris were very professional and the Company's willingness to perform crawl space remediation on short notice was superb. The individuals performing the remediation work did a great job and were very hard workers putting in many hours to complete the job on a timely basis. They also did a great job at cleaning up behind themselves and leaving everything exactly as it was found. I would highly recommend this company to anyone needing the services they provide."

Basement Waterproofing questions, answered by experts

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.
