"The entire waterproofing job was done in 5 days, Monday to Friday. There was a lot of work that needed to be done and it was quite extensive. All work was done according to the original quote plus there was an additional work that needed to be done that was not picked up by the original quote. We had expected some unforeseen "surprises" due to the horrible condition of the basement walls and knew in advance that this may happen. (and it did) Aside from that, everything was done according to contract and a few extra things were done that we were not charged extra for. That was a very nice gesture on the part of Stay Dry Waterproofing. We would highly recommend using Stay Dry Waterproofing to fix up your basement issues. Pictures submitted here only show one side of the basement. The entire perimeter of the basement was worked on and waterproofed."

"My basement is dry and within the 4 -6 weeks after the job the humidity levels where at desired levels and stayed that way. The crew was great and the after care and follow up was above expectations."

"Mid-State Basement Systems came highly recommended by a good friend from Buffalo, NY and they did not disappoint. From start to finish they were very professional yet personable. Larry & Phil in the initial stages of the basement inspection and a reasonable quote. Silvino and his team who done the actual work was incredible, done with absolute excellence. They were here when they said they would be and finished the job a day ahead of schedule. I am thoroughly pleased with this company, first class. I highly recommend them if you need work done on your basement.******"

Basement Waterproofing FAQs, answered by experts

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.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
