"Initial work was acceptable, though they left a significant mess afterward. The real problem began with their ?Warranty,? which must be renewed yearly. My elderly mother missed a payment or two because no reminder was ever sent. When we tried to resolve the issue, Anthony (Tony) L. was extremely aggressive on the phone. Tony L. insisted we would need to pay $3,000 to recertify the work. When we asked about installment payments, he said ?No.? When we asked if they could set up automatic withdrawals to prevent future missed payments, he again said ?No,? even while boasting that they are a national company?apparently one that can?t manage automatic billing. When my elderly mother mentioned contacting the BBB, he threatened to sue her. He then made repeated calls to me and threatened to ?make trouble? with my employer. It is impossible to recommend a company that tolerates this kind of behavior from one of its service managers. Avoid this company."

"Dale was very thorough in his examination of my situation and gave me clear explanations of what was going on. Other firms that quoted the work insisted that the entire basement needed to be done. Dale said that we only need to fix what is leaking. Cost to do that was one third that of other bids. Crew was on time, prompt and thorough. I would definitely use this firm again."

"First there were a couple of delays due to COVID, the weather, and a truck broke down. The window guys were over 2 hours late. While excavating near the house, the workers “accidentally” broke our water main. This of course was our fault and cost us an additional $3000! Read your contract. There is a small clause about accidents not being their fault. Subsequently, we had no water for two days and a large plumbing bill from a plumber they sent. This may not be over."

"The project went very well! Mike is terrific. The crew came as scheduled. Explained what they would be doing and did a nice job.The first part of the project involved trenching the basement floor along the three walls. This was the dusty and loudest part of the work since they use electric jack hammers. Make sure you cover everything. They did a great job cleaning up the area they worked in but you will still have dust. We had a minor problem and came to a mutual agreement for solution. Nice people to work with, great job!"

Basement Waterproofing questions, answered by experts

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Homeowners insurance may cover basement flooding, but only if a covered peril causes it. For example, a burst pipe may be covered if the event was sudden and accidental, not caused by wear and tear or homeowner neglect. Flooding caused by extreme weather is only covered if you have a separate flood insurance policy.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.
