"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

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.
