DryZone Basement Systems, Inc., is your local expert for ALL THINGS BASEMENTY! We specialize in basement waterproofing, foundation and crawl space repair, as well as sump pump installation. We offer free estimates for property owners across Massachusetts and Rhode Island. The company is a trusted and valued member of the Basement Systems network and upholds the high standards of the company. DryZone Basement Systems, Inc., thoroughly trains their staff and experts for crawl space and basement waterproofing at the Basement Systems, Inc., corporate headquarters in Connecticut and always offers a 100% customer satisfaction guarantee.
"The system was installed so that the pipes were pitched away from the sump, the pipe from the sump outside leaked back into the basement, and the exterior drain wasnt dug to grade so water backed up towards the house. When contacted about the issue, dryzone sent out a tech who confirmed every issue. The company then refused to fix anything without a second opinion. A month after I filed a chargeback, the GM called to "apologize", and made it sound like he wouldnt contest the chargeback, but offered no remedy to the situation. He then contested the chargeback and lied on the chargeback rebuttal. Eventually they settled for a partial refund. Terrible company, dont recommend."
