The quality of the work exceeded my expectations, and the finished basement turned out even better than I imagined. Everything was completed on time, and they made the entire process smooth and stress-free. I would absolutely recommend Ideal Solutions to anyone looking for basement remodeling or home improvement work."

"I contacted Proactive to replace my water heater because my current oil system a 5 yr old system kept flooding my basement. The tech looked at the system and spent about two hours on his phone reviewing the system. finally he figured out that my return temp was set too low and was automatically expelling the hot water on the ground outside my water tank. I was elated. So many times I called plumbers and the oil company who swapped tanks and switches , costing me several thousands of dollars. when he left he didn't want to charge me even a hundred bucks, the time he spent researching the problem. I tipped him big time. He was worth it. He saved me from unnecessarily buying a multi thousand dollar new system, and he ended the constant and expensive flooding in my basement. Yes, if necessary, I will use Proactive Comfort again!"

"Morton Excavation was GREAT! I asked for 2 estimates, one with a small retaining wall, one without. After receiving the estimates, I contacted Morton and asked how soon could they get started? “Next week, and we should be done in a couple days.” They did have to put me off for one day, but they completed the job in 2 days, cleaned up the work area, and did an excellent job. Thanks!!"

Basement Waterproofing FAQs, answered by experts

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.
