"Cody was fantastic. He showed up on time for what was suppose to be a small job but turned into a much bigger one due to the issue being more serious. He stayed until the job was done even working in the rain. When he was done the cost was slightly more than the initial estimate because the job was much bigger. Even then the price was extremely fair. He is local to the Lexington area and enjoys what he does. He wore shoe covering when he entered my house and left no mess and was extremely respectful. I urge everyone to give Red’s Plumbing a chance. You won’t regret it."

"

I was extremely pleased with All Dry.  They gave me many options to fix my flooding basement problem without any high pressure sales techniques.  The crew did an awesome job and were very courteous.  I made a few changes as the install progressed and they handled everything with a smile.

There are a few companies that do the same type work and I have used 2 of them.  I would not hesitate to recommend All Dry.

"Life Savers!! We live in an older house with a very small bathroom. We had a home inspection recently and were altered to some major subfloor, sill and joist damage. We knew it was in rough shape but the inspector used terms like “100% moisture and “previous repairs poorly completed”. I called a few other contractors and remodel companies that started to throw around some huge numbers and timelines to make the repairs. The consensus from them was the tub would have to be removed before they could do any subfloor repairs. In a house with one shower that wasn’t really an option for us. I saw the reviews for the Crawlspace Medic and decided to give them a call. It was the best decision I could have made. Sharon, Paul and Stanley were great; they made the process very easy and efficient from the initial phone call to the installation. Paul came out to do the initial visit (11/14) and assured me he had seen much worse and his company had developed methods to do all the necessary repairs from underneath the house leaving the current bathroom intact. The quote arrived the same day and was extremely reasonable. They got us on the schedule right away (11/20) and on the day of the repairs Nick and his crew arrived on time and were very professional. The job was scheduled for two days but they completed it in one and did a great job. We no longer have to worry about falling through the floor. They also provide a follow up inspection in 90 days and informed us of a couple other minor leaks that were noticed while completing the repairs. Crawlspace medic is a great company and I would 100% recommend them to anyone needing their services."

"Black River Landscaping went above and beyond my expectations. After having to completely replace a sewage line full of roots, we were having soil erosion issues outside of the house and flooding issues inside the house. Black River Landscaping put in a French drain, fixed the clipped underground gutters left by the plumbers, and re-sod the whole area. My yard has never looked nicer!"

Basement Waterproofing questions, answered by experts

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
