"We’ve had a lot of crews in our home for various projects over the years, and I have to say this was one of the most courteous. They worked hard, navigating through our kitchen to access the basement and I really appreciated their efforts. Thank you MTU, we now have safe walls in our cellar and fresh beams to keep the house standing ;)"

"From the minute they got out of the truck to check our project, to give us a bid we knew they were the company we would hire. They seemed to know what we wanted by way of design and finish, before we spoke. Where other companies had said flat out “We won’t do this.” “Too much work removing old concrete.” Poor access.” Moli said, “Yes, this old concrete gotta go. But, it’s no problem. We bust it up. We take it out.” At the end of the first day all of the old concrete had been removed and taken away. At the end of day two all the forms were set. Day three was rebar and detail work making all ready for the pour. Day four The concrete was poured stamped and finished. On day five everything was picked up cleaned up and they were gone. These are good people. They do good work and they are as honest as the day is long."

Basement Waterproofing FAQs, answered by experts

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

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.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.
