"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."

Basement Waterproofing questions, answered by experts

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

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.

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.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.
