"Mixed review I had spoken with other radon remediation companies and received quotes before meeting with Erickson Foundation Solutions. The salesman, Chris, seemed much more thorough in his approach and he gave a presentation explaining radon, its danger and the process to remove it. The quote was slightly higher than another quote, but I felt more confident. And with the added fan moisture guard, the system came with a 10-year warranty. So I agreed to the proposed plan and paid a deposit. Later I decided to not install concrete in the adjacent (but not connected) basement/crawl space. I asked Erickson to quote installation of plastic sheeting to seal that space. John, the sales manager’s quote doubled the total price. I already had found durable plastic sheeting for about $300. So how would that become $2000 extra? John explained that there would be a drainage mat under the plastic and it would be attached every few inches to the walls and then sealed with caulking. But besides sealing the area, the quote also included another extraction hole and piping to connect it to the fan. This seemed to me like over-kill for a 1200 square-foot house. But he said without the second extraction location, they would not warranty the job. So I accepted the “up-sell” and signed. Today the office called to tell me when the crew would arrive and they arrived on time and were very pleasant. However, they did not have the drainage mat. They called their supervisor and was told that it was not included in the quote and would be an additional charge. In fact it had been a verbal inclusion, not written. The crew was surprised that a second extraction hole was quoted, since the radon levels were not very high to start (3.8 and 5.4). So I feel that I accepted a possibly unnecessarily elaborate system, more elaborate than I probably really need, for twice the price. And didn’t receive the drainage mat that I was told would be part of it."

The quality of the work exceeded my expectations, and the finished basement turned out even better than I imagined. Everything was completed on time, and they made the entire process smooth and stress-free. I would absolutely recommend Ideal Solutions to anyone looking for basement remodeling or home improvement work."

"Chris and his crew went above and beyond the contact we had with. While he was here we had him preform an additional contract which was also completed in a timely manner. I would certainly recommend him for the landscaping that he did for us. We have additional work that we want done in the spring and Chris will get the first call."

"We hired Tyler and his crew from Quantum Contracting LLC to build a 10 x 12 pool deck and they did an awesome job. Hardworking, pleasant and professional. They cleaned up the area every night when they left and when the project was completed. Very skilled in their detail and carpentry work. We are so pleased with the end result and look forward to using it this summer. We would hire them again for any project and we highly recommend them. Paula and Stephen Russell"

Basement Waterproofing FAQs, answered by experts

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

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.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly
