"Francisco has to be the best service contractor of any trade. Very HONEST, responsive and great quality work. We had several other basement waterproof system contractors out, and all were clueless or gave inaccurate information. Francisco's knowledge and expertise was impressive. Now, after several months and heavy rains, the basement remains perfectly dry. We called Francisco back for some minor cosmetic sealing, and he responded perfectly again, on a weekend day. You won't regret calling Francisco"

"We asked David to help us determine if we had a water problem in our basement. We live in a 100+ year old house that has a history of water damage and disruption in a French drain system. Before investing in thousands of dollars of work that David’s company could have benefitted from, we wanted an expert opinion. David has an engineering background and lots of experience with foundations, water control solutions, and crawlspaces/basements. He did a thorough inspection, reassured us that there was no problem, answered a lot of questions, and pointed out a few additional things we could do to further protect our home from water. None of which resulted in business for him. He spent 45 mins with us. He’s down to earth, practical, knowledgeable, and ethical. A great combination in a contractor!"

"They did removal of old broken-down encapsulation, redid, made air-tight, waterproofed, mold and mildew treatment, French drains on two sides, drained cinder blocks, filled holes left from previous drains and vents, installed new sump pump and dug in, leveled-the slanted area for proper drainage, installed new exterior drain, relieved 4" of standing water and established proper flow. PROFESSIONALS TO THE MAX!!! It's gorgeous and clean and brilliantly done. I can't say enough good stuff about Patrick and his crew! Even after traipsing in and out with wet, muddy old encapsulation materials and debris in the rain, they left my place in sparkling condition -- NO evidence of them ever having been there! No cig stubs (they don't smoke), no old drink bottles, not even a cleaning cloth. Swept, washed drive, vac'ed ramp, washed entry ladder. VERY knowledgeable. Not my first encapsulation and sump pump situation but by far THE BEST. Quality materials, good work ethic, a pleasure!"

Basement Waterproofing questions, answered by experts

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.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

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.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.
