"I had a wonderful experience with MidAmerica Basement Systems & highly recommend them if your having any waterproofing needs. My project: I purchased my home 3.5 years ago & it started getting water in the basement last year after the outside drainage & tiling system put in my previous owners failed miserably. It would literally be full days of pumping water out of multiple locations in my basement. There were issues of moisture even with two dehumidifiers running & subfloors the crew took out & cleaned up after as well. Scheduling: They will schedule a ways out for appointments but only because it's a high demand working system. Others may be able to offer services quicker but there is likely a reason they are not busy. I got several bids in the time I waited for my MidAmerica Basement Systems appointment & encourage you to as well but definitely wait until after your appointment to make a decision. They were not the cheapest but had the best guarantee (100%), best working system, and a few things I've learned in my 20 years of homeownership is if you go cheap & need to redo it your typically spending more than if you did it right the first time & your home is not something to skimp on or take chances. MidAmerica Basement Systems will send you detailed emails as to what you can expect for each appointment. They will mail you a packet of information regarding different systems that work vs fail & throughly explain the dangers & hazards water/moisture in your home will cause. Our basement got so bad from the Derecho the only dry place was in our basement was the shower & my celing developed black mold quickly from the moisture. Not only did they offer a system to waterproof my basement but a whole house dehumidifier & air purifier which would have saved my ceiling if I had earlier. Sales: I had Justin A for sales & he was very thorough in listening to my problems & needs as well as took his time in explaining & showing me how they could fix my issues, how the system works, as well as answering all of my questions with detail & no hurry. He was absolutely great about changes I made in adding work later on (before my appointment) as well. He doesn't make it feel like a sales pitch, is not pushy at all, & really works to get you the most work in your budget (prep & finish work offered), as well as taking his time with you through the entire process. The office crew: The office staff was very polite & helpful. I mostly worked with Desiree S & Kim B who are extremely responsive in working with me. The Crew: My crew consisted of Brandon T, Sam G, & Ethan T who I highly recommend! These young men are the exact type you want on your project! They are polite, respectful, hard working, efficient, trust worthy & have a great work ethic! They not only got the job done in the time allotted but left my basement incredibly clean which I didn't expect. They thoroughly go over the work before & after as well as answer any questions you have along the way & explain in detail any changes if something isn't to plan before just doing something differently. They called before heading to my house as well which I thought was very courteous. I imagine they have a lot of great workers but anyone I know that I send their way, I'll have them ask for these men as the crew on their home. Overall: Overall I give them 5 stars & they earned it all the way. I will say it's winter so not when one typically gets water in their basement so I am unable to review how the system works fairly. I do, however, plan to leave another review after we get some lovely wet Iowa spring weather or melting of our snow mountains to test it out. I don't expect my review to change & feel confident in the upcoming months & years. Thank you MidAmerica Basement Systems!"

Northern Duct Seal seals duct work from the inside by use of computerized tools and equipment. The process takes one day and our technicians will provide pre-seal and post-seal duct leakage reports on the spot. The basic steps to do a duct seal are: 1) Pre-seal Test is done to measure duct leakage, 2) Registers, returns, and air handler coil are blocked off with foam plugs, 3) A UL-tested and approved aerosol is injected into the pressurized duct system, 4) A Post-Seal Test is performed to measure improvements and 5) A complete Report and Certificate are printed to provide the customer with a record of improvement. Duct sealing provides a solution to high energy bills, air flow/air balance issues, uneven temperatures, hot and cold rooms, excessive humidity, musty odors and fume smells from stored paints, solvents, pesticides, and radon gases. Northern Duct Seal will reduce duct leakage by up to 90%, saving customers an average of $600 - $850 a year, with a 2-3 year return investment, depending on variables such as weather, system usage, energy prices, and home design. Northern Duct Seal offers a 10- year warranty on the seals created by our technicians. The sealant itself has been UL tested and approved and is considered non toxic by OSHA. For a demonstration video of the duct sealing process please see the 'Ask This Old House' Video located under the Media tab on this page.

"So disappointed with this company. I own a house for my daughter to live in while she is in college. The house is 5 hours from my residence. The house has been having water in the basement. I turned to Angi to get a reliable list of waterproofing companies. When MidAmerica Basement Systems called me to set up a time to give me a free quote, I was instructed I would need to be at the house. I let them know my situation of living 5 hours away and that my 21 year old daughter would be at the house and could FaceTime me during the appointment. This was not good enough as it is "company policy" to have the owner at the house. I spoke with the initial employee who wasn't willing or even tried to figure out a solution. Her solution was to send my call to the manager, who when answered acted like she had no idea why she was getting the call. I explained to her again that I lived 5 hours away and would not be able to be at the house, but we could use technology and I could FaceTime. This again was denied and a viable solution was not even talked about. Never did I feel they wanted my business or in any way were willing to work with me. I can't imagine I am the only one who does not live close and has had issues. It is 2021 and in the middle of a pandemic. Why FaceTime isn't an option is extremely frustrating and confusing. The customer service I received during this call by various levels of employees was also disheartening. I would never use them after this experience."

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.
