We bring something completely different to basement waterproofing and waterproofing in general. We are not the company to call if you have large amounts of water entering your foundation or basement. However, if your foundation is in somewhat decent shape and un-painted. We can stop the moisture from seeping through your walls and floor that cause stored items from being covered in mold and mildew and make your basement far healthier and a truly usable and dry space permanently. With a one-time application using 100% green products that do not change the surface of your concrete surfaces. You can safely store items or furnish your basement and even install hardwood flooring with confidence. Our waterproofing works by using crystalline technology that enters your concrete going where the moisture goes deep into your concrete walls and floors. When moisture is present these crystals expand up to 16 times their size sealing the moisture out of your basement including cracks and joints.

"He has done a ton for stone walls for me over the years. He has always done an excellent job for me over the years. He is one of those rare people who does everything to the best of abilities."

"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."

"Thomas and Angelo (his crewman) were fantastic. (He had more crew, but Angelo was the only one whose name I knew.) They correctly diagnosed the problem (foundation cracks), sealed everything, installed a new sump pump and redid the flooring. They kept me informed every step of the way and started work within a day or two of hiring. The basement has remained dry as a bone ever since. One thing to note: They do require payment quickly (not all upfront but soon) and do not take credit cards."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Gardner, MA

Cleaning your crawl space is a worthwhile investment for several important reasons. A properly maintained crawl space prevents structural damage by eliminating moisture that can deteriorate wood supports and metal components. It also significantly improves your home's indoor air quality by removing allergens like mold spores and pest droppings that can circulate through your living spaces. 

Additionally, a clean crawl space contributes to better energy efficiency by allowing proper insulation installation and reducing humidity levels that force your HVAC system to work harder.

Several warning signs indicate your crawl space needs professional attention. Look for musty odors throughout your home, unexplained increases in allergy symptoms, higher energy bills, visible pest activity, or moisture issues. 

Other indicators include sagging floors, warped wood, visible mold growth, standing water, or damaged insulation. If your crawl space hasn't been inspected in over a year, or if you've recently experienced flooding or severe weather, it's advisable to have professionals assess the space even without obvious symptoms.

Most crawl space cleaning projects take between one and three days to complete, depending on several factors. Simple debris removal in a small, relatively clean space might be finished in a single day. 

More involved projects that include mold remediation, water damage repair, or pest control require two to three days. For large crawl spaces or those with extensive contamination, the timeline might extend to a week, particularly if additional services like encapsulation are included in the project scope.

You can remain in your home during basic crawl space cleaning. However, if the project involves mold remediation or pest extermination with chemical treatments, temporary relocation might be recommended, especially for household members with respiratory conditions or chemical sensitivities. 

Professional cleaning companies use containment procedures to minimize the spread of dust and contaminants into living spaces, but some disruption is inevitable. Discuss your specific situation with your service provider to determine the best approach for your family's needs.
