Celebrating 30 years of service, our family has specialized in structural foundation repair and basement waterproofing. We have built a long-standing tradition of excellent work and a commitment to total customer satisfaction. Contact us today and let's put your problems behind you once and for all. Basement Waterproofing: We custom design the SafeBasements Waterproofing System to meet your specific needs. Once the system is installed, it takes care of itself, backed by our Lifetime Guarantee. All you need to do is make an occasional check to make sure the sump pump is operational, after all, it is a small appliance, Bowed Basement Wall Repair: We stabilize and in time straighten basement walls that have bowed and cracked due to poor grading and expansive soils. We address this problem using the state-of-the-art SafeBase Wall Anchoring System, SafeBase Waler System, or the SafeBase Carbon Fiber System. Settling Foundation Repair: To address the problem of foundations that have settled vertically or rotated outwardly, we use the SafeBase Foundation Piering System. This system utilizes proven engineering methods to secure and stabilize settling foundations by attaching SafeBase Brackets to the footing and hydraulically driving steel columns deep into the ground until they hit bedrock or equal load-bearing strata.

"I researched basement waterproofing solutions and was considering doing it myself. Then I found Safe Basements and read the literature about their product/process. To me, it seemed better than other similar products. I was surprised that they cover my place -- 2 hours into Wisconsin, or 3 hours from Litchfield. Brad came out to inspect the problems in my basement -- horizontal cracking, bowing, and water intrusion. He was able to explain the causes of those problems as well as others that I hadn't noticed. We agreed to pay for anchors to stabilize one wall that was bowing, and install drain tile and a sump pump. I'll be honest, I didn't shop around. I have no idea what other companies are charging for the same services. I normally get 3 or 4 bids or other opinions. I felt comfortable with the amount of research that I'd done, the knowledge Brad seemed to have, and the information about the products that I decided to hire Safe Basements without talking to other companies. I don't regret that decision. The wall anchor/stabilization crew called me before leaving Litchfield. Their ETA was pretty close to the actual time of arrival. When they arrived, we discussed the work being done. They did the work. They cleaned up. They gave me information about the anchor system and what I needed to do to correct the bowing and cracks. Everything was done as expected. The drain tile/sump crew was stuck at a previous job. They called me the day before (Tuesday) my job was expected to start to let me know there would be a delay starting my job. He then called in the middle of the start day (Wednesday) to let me know, they wouldn't be to my house until the next day. I was expecting a call between 7 and 8 on Thursday to let me know they were leaving Litchfield. Instead, I got a call at about 7:15 to let me know they were 15 minutes from my house. When they arrived, we talked about the work to be done, they cocooned my stuff in plastic, and they went to work. I think they worked until about 7 that day. They returned on Friday at about 8:30, having stopped to dump my concrete and dirt and to pick up gravel and concrete. They worked until about 10:30pm on Friday. I appreciated that they finished on Friday even though it was later than I expected. They cleaned up everything thoroughly, and walked me through the details of the sump pump and battery backup systems. Even though they'd driven a long distance, worked two very long days, and it was very late Friday, I didn't feel they rushed through. The job was complete. I think they would have stayed later if I'd had anymore questions. Unfortunately, one of the workers left his very nice tape measure, and I have not been able to get it back to him."

"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 questions, answered by experts

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
