"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 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!!"

"Gerald took the time to understand my needs for making a basement for finished. He explained the options. We decided on self leveling concrete and covering the exposed French drain we had. We decided on a schedule, everything was done on schedule. I now have a Waterproof basement floor with total usable space. Extremely satisfied with the teams work."

"Hired them in August to repoint all of the foundation outside and about half inside of the basement (brick repointing) also added some waterproofing and everything looks great and I haven't had any water come in the basement as a result of Ben The Mason and his son's great work. Highly recommend them for any masonry project, we also talked about redoing my front steps which I will follow up with sometime in the near future."

I hired this company to waterproof my foundation and to install some new pointing along my foundation walls. We also installed some drainage around my home. Our issue is completely resolved, and I am very happy with the results of the work this company has completed. I highly recommend this company, It has been a great experience."

Basement Waterproofing FAQs, answered by experts

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.
