"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."

"I highly recommend Start2Finish Waterproofing. Ed was wonderful to work with. He was timely, informative, and honest. There?s no inspection fee like most other companies. Their quote was very reasonable and has a lifetime warranty. Bob and the install crew were very efficient and left my basement in the same condition as when they came. For basement water issues this is the company to use!!"

"This business was professional, communicative, and on time from my initial inquiry to when the job was performed. When I initially called, they were able to get someone out to provide a quote within 2 weeks and had me booked within another couple weeks. I was provided a quote online, and that's what I ended up paying. No fine print. Everything was completely transparent. William and another person came to do the actual sump pump installation. They were on time and finished a rather challenging installation (the pipe exit needed to be in a different room than the actual pump) within 4 hours or so. He explained everything to me clearly and was friendly, courteous, and professional. I would absolutely recommend these guys if you're looking for any kind of basement repair/waterproofing."

"We hired Leal Restoration to clean up water damage on three floors of our house. They came early on a Saturday morning, worked all weekend and finished the job on Monday. This included drying out the area, removing debris, and replacing a ceiling. The work was done efficiently and carefully. Leal turned a disaster area into a clean and back to normal living space in 3 days. Amazing!"

"Khaled and his crew built a large 2-story garage for us and it came out wonderful. Khaled managed multiple sub-contractors, engineers, and the town's building department. The build did not always go according to plan and it did end up taking longer than anticipated, but that is to be expected with construction projects - especially in this worker & supply-limited climate. Despite delays and setbacks, Khaled always has his customer's interest at heart, and will make sure that the work is done well. I would recommend Abalia Construction and will use them again in the future."

"They did an excellent job repointing the exterior of my foundation and brick piers in the basement. I had a tight schedule and they worked through the weekend without me asking. Showed up early and worked long days to get it done. One of the guys was able to shimmy into a very tight and awkward spot due to the porch structure to get every area of the foundation. I pointed out a couple missed areas and they happily came back the next day to finish the job. I will be using them for future projects."

Basement Waterproofing FAQs, answered by experts

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.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
