"Everyone I have spoken with and talked to and worked with at Bay Crawl Space and Foundation has been exceptional. My husband and I recently purchased a new home and were interested in planning for improvements to the basement/crawlspace as we live in a flood zone. I had several companies come out and look at the space, and Bay Crawl Space was easily the best experience I had. David was very knowledgable and great at making reasonable recommendations for my crawl space and basement. He discussed multiple options with me and was candid about price, giving me his honest, practical opinion that fit within what we were looking for. Their pricing structure was easy to follow/compare and the quote was reasonably priced, if not a little lower than other companies I spoke with. There was a 6 week delay between inspection and installation of our new sump pump, but this wasn't an emergency, so we didn't mind the wait. However, once scheduled, I received several calls with great communication and payments were easily made online. When the time came for installation Matt and Sharron arrived on time, answered all of my questions/concerns and did a fantastic job installing our new sump pump. Two days later the electrical team Adrian and Paul also came on time and did quick work installing the outlet and lights around the sump pump. They even took a look at our electrical panel and answered some questions for me unrelated to the job. All members of this team were communicative, respectful, and great to work with. They left our basement clean and the installation looks really professional. It has been working well with the heavy rains we have recently been experiencing and I would recommend all of the members of this team if you have any concerns about your crawl space/basement. They have all really helped give me peace of mind and I will use them again if we have any other concerns Crawl Space or basement concerns."

"Nearly three years ago, I asked JES to install a waterproofing system around my basement (in 2016). After they did this, there was no further flooding or leaking of ground water into my basement. In addition, the dehumidifier makes the whole house smell fresh."

"They had to dig out a whole wall out of my basement to stop the leaking. They cleaned the basement wall and they resealed it with the latest technology. They were very friendly and cooperative. They worked hard, and came when they said they would. Everything you would hope a contractor would do that did."

"He was very helpful. The issue with the vent was not that it was dirty but, the cent is too long. He came over and went under the house and in the basement to figure out the problem. He let us know we should cut an access panel in the deck to make sure the vent is clean and set up properly."

Basement Waterproofing FAQs, answered by experts

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.
