"They advice, and had all our questions answered on sensible and affordable options. Very knowledgeable, prompt, polite, efficient, and thorough team! We are happy with their waterproofing services in our basement (fast sump pump and a grate trench with a discharge line that goes 15 feet to the outside bubbler) as well as crawl space shield installed under our addition. It works well, and Pioneer checked a month later and a year after for inspection and cleaning. A+ work and workers."

"I highly recommend Key Waterproofing. I have a main basement and a small storage basement. Both flood every time it rains. Our drainage was not working and we called Key Waterproofing. Ed and Wendell along with their team were fantastic. The job was finished within the timeframe we were given and the price was very good compared to their competitors. Overall we are very happy with the results."

"Johnathan is a honest hard working man. He walked me through the whole process and delivered exactly what he promised and more! You just donâ t find customers service like this anymore. Itâ s been over a year since my basement drainage system has been installed and he has checked in on serval rain storms just to make sure everything was ok! He has even given my some pointers on things I can do around my home to further improve my drainage issues. He even called me back from his tropical vacation. He definitely goes above and beyond . I have had many contractors over the years and he is at the top of my list! I would highly recommend him!"

"Contacted Mark within 3 days he was at my home and providing a detailed quote. Might seem small but he was the only one out of 4 contractors who actually measured the space to provide an accurate and detailed estimate. He while discussing what I wanted with me made many recommendations and even mentioned ways to get the job done but at a lower cost. He had the estimate to me within 2 days and it was super detailed and broken down with 3 different ways to complete it. He was on time daily as was his crew. Work areas were cleaned daily. He closed up a broken window for us, redid a dirt floor with drainage and concrete, repointed and waterproofed our basement foundation, ripped out and fully replaced basement access stairs. He even noticed a window that was broken we didn’t and closed it up for no charge. He added a drain to the exterior steps at no charge wasn’t in contract he just knew it was needed, the steps he replaced had asphalt around them and he even repaired the asphalt at no c"

"Mr. Aponte is a true craftsman and professional. We needed a bedroom ceiling replaced and window framing, trim work done. Mr. Aponte reached out quickly and was able to visit us for a quote in a short amount of time. His pricing was very fair and he had a very creative solution to our problem. Mr. Aponte was an excellent communicator both on site and by phone. He always showed up exactly when he said he would. It was very much appreciated! Our ceiling is absolutely perfect. Now, you can’t tell that any work was done at all, and I am pretty picky. His craftsmanship is incredible. He also pointed out some problems that a different installer had made which allowed us to have our window re-insulated and waterproofed. That will save us so much money in heating costs and potential insect, water damage—he has a real heart for his clients and wants to make sure their house is perfect as possible. We will be hiring Mr. Aponte again for additional projects very soon, thank you so much!"

Basement Waterproofing FAQs, answered by experts

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

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

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.
