Tennyson Construction - Wet Basement Specialists is the leading basement waterproofing and foundation repair company in Southern Minnesota and Northern Iowa. In business since 1981, they have worked in over 4,200 basements. Our interior tiling system to repair wet basements is backed by our transferable warranty, transferable to future owners of the home. If the basement foundation has problems (cracked, buckled or bowed basement walls), Tennyson Construction can straighten, brace, repair or replace basement and foundation problems. We offer no obligation free estimates with no high pressure sales tactics. We examine what is going on, tell you what we would do to fix the problems, bid the project, and leave the decision up to you. We do our own work, without any subcontractors. We feel one of our biggest advantages of Tennyson Construction is that we are not a Franchise business (we can tailor the right solution to each type of basement problem - no incentive to push products and services that may not be needed to meet franchise quotas). The second is that we specialize in working in basements, so our focus is always on the basement problems and solutions to those problems. The third is we back our work. Finally, most of our customers' projects begin with referrals from other customers, real estate agents, building officials, insurance agents, cleaning companies, and plumbers. Our projects are done in less than four days with qualified basement professionals. If our proposals are accepted, usual payment for those projects is done upon completion. Our company takes pride in its work, and we are proud of our small-town, locally-owned, family-owned business. Our employees really enjoy working with customers, as they see the joy that a family has when they get to enjoy their basement even more after our work.

"They were very good at selling the solution, but there was a big gap on the execution of the project, and took multiple iterations to get everything right, I even had to get into the solutioning with the team myself. It is too bad because the technology seems to work fairly well, and that’s why they are getting 3 stars, but I would not use them again."

Installation and service of HVAC, plumbing and roofing systems throughout southern Minnesota. Over 40 technicians offer 24/7 emergency service through out our market area. Maintain offices Mankato, Minneapolis and Rochester, MN. Been a leading provider of HVAC and roofing services for over 100 years.

"The person who rated Schwickerts with a 5 star review because they make sure "the customer is satisfied" is obviously had a different experience than we did. They installed new roofs on our association townhomes and during installation, somehow dislodged several unit's furnace vents as well as someone's water heater vent. When Fall rolled around and furnaces were turned on, one customer had water dripping in her attic and down into her home. They came back several times. Couldn't find anything wrong. On third trip, the employees didn't bother looking in the attic; they simply cut holes in her ceiling and found what they said was a disconnected vent to her furnace. They told her she was lucky they found the problem, because the next step was going to be having to go up on her new roof and cut into it. Unfortunately, after they left, water continued to leak into her home. She could not allow the water to continue to damage her ceiling, so she had someone else look in the attic...and they discovered the furnace exhaust had been disconnected in more than one location, and the water heater vent had been disconnected as well. SCHWICKERT HAD THE NERVE TO SEND THIS PERSON A BILL FOR OVER $400 DOLLARS "INVESTIGATE THE CONDENSATION ISSUE" (TO CUT THE HOLES IN HER CEILING), EVEN THOUGH THE PROBLEM WAS CAUSED BY THEIR SHINGLING INSTALLATION CREW AND NOT CORRECTED. Their customer service for the issues WE HAD after installation was extremely POOR."

Radon detection and reduction services FAQs

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay $150 to $800 to hire a local radon inspector, and home-testing kits range in price from $15 to $250 from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.

If radon is present in your home, you can expect to pay around $1,000 for a radon mitigation system or between $780 and $1,250 in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about $4,600 to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing $1,500 to $15,000.

Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.
