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."

**We do not remove oil tanks*** 25 Years Experience with Gunite Built in Pools, Excavation, Drainage, Foundations, demo, grading, sewer, and water installation. Licensed and insured. Quality work with great prices. Call Joe today for a free assessment and proposal of the work you need done!

"After 2 1/2 years of not being able to secure a contractor willing to excavate or property we found Joe who told us, "No problem when do you want to start?" After receiving Joes quote we asked if he could build us a wall also. Joe stuck with us even after we were satisfied with the excavation. He encouraged to order gravel late on a Friday to finish up the site."

Basement Waterproofing questions, answered by experts

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.
