"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."

"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!"

"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."

Basement Waterproofing FAQs, answered by experts

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.
