"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"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!"

"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

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

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.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.
