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."

FAQs for radon detection and reduction projects in Janesville, MN

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.

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.

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.
