"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

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.
