"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."

"Tom just completed a whole house Mold Remediation for me. Attic & basement. The attic which is split into two wings was heavily infested (?), the basement not so bad. This job was complicated by the fact that one wing had no easy access to the attic space. Tom resolved that nicely. He constantly went above & beyond and definitely put in more hours tha he had expected. But- would not take any extra compensation! I would definitely reccommends him for any future work."

"Lou was great to work with- friendly, professional, easy-going, and most importantly, responsive. Even with me having some work travel in between when we spoke and when the work was performed and a couple communication hiccups, Lou and Andrew were friendly and professional and committed to moving forward to get the job done. They showed up when they said they would, did exactly what we agreed upon, and finished up early leaving my driveway looking great and cleaned to boot. I would definitely recommend them and plan to hire then again for any future maintenance on our concrete driveway!"

Basement Waterproofing questions, answered by experts

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

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.
