Crawl Space Repair
Report
Your home is a system, and every part of that system plays a role that affects the rest of the structure. If your crawl space begins to rot, grow mold, or experience structural problems, this will extend to every part of your home.

At Basement Systems USA, we specialize in crawl space problems of all types.
Mold Removal & Remediation
Report
Mold damage in a home can be especially difficult to remove permanently. Without a trained and fully certified technician performing the work, the mold may not be completely removed, or it may simply grow back in a few months.

Mold damages personal property and also can seriously affect the health of many residents within a household -- especially those with asthma or allergies. A single square inch of drywall can contain between one and 10 million mold spores. It only takes three to five of those spores to cause a reaction in a sensitive individual.

Basement Systems USA is your local source for expert basement and crawl space mold removal. We provide thorough testing and can handle all your mold remediation needs, no matter how severe the problem.

We had a pretty large crack in our basement wall that would leak with heavy rains. Basement Systems USA did a Flexispan crack repair and ever since then we've had zero leaks. I highly recommend this company for your basement waterproofing needs.

The service before, during, and after the work they performed in our home was outstanding! Very friendly staff and helpful when setting everything up. The crew was polite and happy to answer any questions while they worked. Cleaned up after themselves very well too! Our basement has never felt better and we feel confident that the work Basement Systems USA did for us will last for many many many years to come and help preserve the integrity of our basement space.

Basement Systems installed a SaniDry system in our basement and the results have been incredible. The air quality in our finished basement had been damp, dank and musty smelling until the installation of this system. The SaniDry dehumidifier is powerful, quiet and completely automatic and the basement air quality has never been so good. I can say with complete confidence that along with proper basement waterproofing techniques this an an investment a homeowner will never regret.

I had a great crew that came out starting from the sales person on to sean and his crew.answered all my questions. Went thru whole basement and explained 5 types of vapor and waterproof products along with cost. They were doing such a great job i ordered lunch. So need your basement done and feel comfortable then this company is your answer hands down.

From start to finish this company exceeded my expectations. We needed French drains, a Sump Pump, and some reinforcement done to one basement wall. The salesperson, Tim, who came out for the initial estimate was thorough and helpful. He explained everything I needed to know, answered all of my questions, and put absolutely NO pressure on me to make a decision.

After I decided to go with Basement Systems USA, it was only about a day before they called to schedule the work. They were able to schedule the work for about a month from then. They completed the work in 2.5 days. They were sure to put down tarps for walking through my house and hauled out 100% of the debris from jack-hammering my concrete floors. I was thoroughly impressed from start to finish and highly recommend them!
