"Semi competent unbelievably unreliable and totally inconsiderate of your time I contracted them to do waterproofing in my basement and install an egress window. The waterproofing was done in June and it did great keeping up with the +10" of rainfall we got a few weeks ago, so for that I am pleased and couldn't be happier with that part However, I was supposed to have the egress window installed Monday 9/17 and 9/18. On Thursday 9/13 I noticed the underground lines had not been marked yet so I called them to see if I needed to do that, they told me the foreman that does the egress windows had a medical emergency and they didn't know when he would be back but were getting someone else trained. She also told me she tried calling my home phone on the 11th but no one answered and she could not leave a voicemail, this I believe but she said she had my cell phone as a backup number why not call that? isn't that why they had the backup number? Now I see there was a guy that was getting concrete leveled 2 weeks ago but they had to back out because they claim the foreman for PolyLevel was injured and will be out 6-8 weeks. Either their stories reek of B.S. or this is a poorly ran company to have one guy cover egress windows and/or concrete leveling with absolutely no backups in as big of a service area as they advertise. The scheduler for egress offered to call me once a week to give me an update but judging by the other posts I shouldn't hold my breath. What's worse for them is I have 2 other services that could be done to my house, but as of now I won't even consider them. It's a shame how one bad experience can completely destroy a great one. I actually went with these guys over a lower bid for the same work because these people seemed more professional, I guess I was wrong. I hope I never have problems with my waterproofing systems because I can only imagine the nightmare these people are to work with"

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.

MidAmerica Basement Systems is your premier locally owned and operated company that specializes in foundation repair, basement waterproofing, crawl space repair, concrete leveling, and radon mitigation.

"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."

FAQs for radon detection and reduction projects in Keystone, IA

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.
