"I am not pleased with the service I received! They damaged my waterline and stated someone would be out to fix it. It's been 9 months and no one will return my calls nor have they come to fix what they damaged! They ruined my lawn and never came back to replace the soil they dug up! They ruined my basement floor and I had to replace my entire floor! They said they would be out to test the sump pump and drains that were installed, again, it's been 9 months and no one has followed up with me! I'm really concerned that the lifetime warranty they say I have even exists!"

"Salesman here 6 hrs. Quoted over $30lk got down to $25,500. Of course it was a good for today sign now price I had more estimates lined up but after 6 hrs and him acting like he was my husbands new bf and beer buddy he signed. Scheduled walkthrough- that was cancelled. Started work and had ?issues? that walk through would have found. Blew circuit breaker in workshop of basement, we now need an electrician bc even w replacing the circuit breaker w a new breaker it still turns off. Quotedi time length/ what they would be able to do by salesman- all wrong. Workers say it will be twice as long and what sales man said they could go around they can not. Workers are extremely polite and nice. Will update review when they are finished w work. Today 7/30 will be day 3. "

"Had Betts Structural Engineering come and look at the foundation of a house we were in contract on. Josh came out and was professional and informative. He informed us the foundation was failing and explained what needed to be done. He throughly explained everything and told us how we could do it ourselves for much cheaper than a contractor could do it. In the end he saved us from a long and expensive process if we proceeded with the house."

Basement Waterproofing questions, answered by experts

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.
