"Wonderful job !! My review is on the yearly crawl space maintenance and inspection. Thank you Caden Dyson for being so professional and a nice person. He takes pictures and sends to you so you can see how it still looks. Last year and this year he found a leak under the house, soooo glad he found it, I joke about having him come back every 6 months to check for leaks,Ha. Thank you Caden Dyson and everyone I've talked to in the office. Brenda M"

"They came out immediately to install new battery-powered sump with storm looming nearby. Came, installed, tested and did not leave until they knew everything was working properly. Very good people. Would call them again for sure."

"I have a very old house and the basement drain has clogged twice in the past two and a half years.
The first time the clog left two inches of water on the floor. Noah Ball came the same day I called and flushed the drainpipe.
He also gave me tips on how to try to keep the drain clear.
Two years later he had to come back for the same reason, although the damage wasn't as bad. This time it was determined that there were roots in the pipe; he cleared it and we have discussed what my next steps will be. At some point the line will have to be repaired or replaced, but prior to that he will do a TV scope to get to the specifics of the problem.
I was very impressed with Noah. He is professional but easy to talk to - and appears to be sincerely interested in doing the best job possible at a reasonable price. I wouldn't think of using another company for rooting. AND, in both cases, he came the same day I called. Now that's good customer service!

"Shane was very responsive and knowledgeable to address the humidity problem in the crawl space and odor being emitted through the vents. His team of professionals installed a dehumidifier, replaced the vapor barrier, and sealed the vents. I'd highly recommend MSG team of professionals for your next repair project ."

"Insulating a crawl space is incredibly expensive (especially for a space that hardly anybody ever sees or goes into), but they did a good job and it has helped in keeping the pipes warmer in winter and reducing damp feeling inside the house."

"Nearly three years ago, I asked JES to install a waterproofing system around my basement (in 2016). After they did this, there was no further flooding or leaking of ground water into my basement. In addition, the dehumidifier makes the whole house smell fresh."

Basement Waterproofing FAQs, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.
