"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

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

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.
