"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."

"We recently had a radon system installed. Thomas was easy to work with, reliable and seemed deeply knowledgeable about radon and radon systems. The process went as described and the basement radon reading decreased in the first few days and has stayed reduced. We had the system installed over a month ago, but I wanted to be sure to give a review."

"IT was great! I have never had a problem working with this company. The people (from the customer service reps to the billing to the drivers) have all been honest and realistic with expectations, answered all of my questions and never charged me more than what is advertised on their website. Patricia and Victoria have gone out of their way to return my many phone calls on the weekends too. You just don't get customer service these days anymore like the bullbag provides.They came when they said they would, did what they said they would do and did it professionally and pleasantlly. It is a pleasure working with such an honest and reputable company. Especially since the dumpster industry has not been know for this! These guys are definitely setting the bar high for all their competition."

"Everything we hired stops masonary to do came out great. They were here when they said they would be here and they never left a mess at the end of the day. The job was done for the agreed-upon price with no surprises. I would definitely hire Staats Masonry again and would recommend them to anyone."

"Can I give A++ ratings? I contacted this company based on good ratings on Angie’s List and a visit to homeowners who had worked with the Ranieris. I was thrilled that they cared about the price and a superior result. They showed up, had thought out the plan well and did the work daily. They coordinated with subs. And they did all of this with good nature regardless of the heat and humidity or pop up issues. They stand by results with utmost integrity. My pool looks fabulous and we are very happy. I would hire them again always."

Basement Waterproofing questions, answered by experts

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

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.
