"Absolute WORST experience I’ve ever had with a company! They are extremely predatory and convinced my 63 year old mother that she had to sign the contract THAT DAY, and she didn’t even understand what she was signing! The first day they were scheduled to do the job, they showed up hours late, and said they “weren’t the right crew to do the job”. We then had to wait a couple weeks for a different crew to come, and when they came they said they weren’t the right crew to do the job either!! 2 weeks later, ANOTHER crew came and said THE SAME EXACT THING!!! So after 3 times of getting the runaround, I was completely FED UP with this horrible company and decided to cancel the contract. They FINALLY did let me cancel, but are demanding we still pay $600! After all they put us through over 3+ months, they had the nerve to charge us $600 for an outlet! PLEASE AVOID THEM AT ALL COSTS! All they care about is dollar signs, not about the QUALITY of their work or customer service."

"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."

"From the initial contact with Trenton Mayes, it was a very positive experience. He came to inspect, knew exactly what needed to be done and made the arrangements. The workers who performed the mold remediation were just as efficient and friendly as Trenton, great staff and great job. The product they use did not bother my asthma and I was able to return to my home."

Basement Waterproofing questions, answered by experts

While it’s possible to live in a damp basement, it’s usually not healthy to do so. Damp air affects your breathing, and it also promotes mold growth and pest infestation that can make living in a damp basement dangerous. You should plan to resolve any moisture issues and set up preventative measures before using your basement as a living space.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Whether interior versus exterior basement waterproofing is better for your home depends on your budget. The majority of water issues that homeowners experience in their basements are due to conditions that start outside of the home. So, to prevent those problems from seeping in, it’s better to stop them at the source using outside waterproofing methods.
