"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 have been getting water in our basement since we moved here a couple years ago. This last time was the worst. Inner Boston came Take a look and figure out the issue. Were very quick to come in and give me a solid estimate. They walked me around the house showed me and explained in detail what the issue was and what needed to be done to ensure that we no longer got water in the basement. They saw that not so great weather was coming up so they came in and got the work done within just a couple days. I mostly spoke with Mark but all super nice and so great to deal with! Iâ m so glad that we chose them to do the job. Highly recommend!"

Basement Waterproofing questions, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.
