"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!"

"We have worked with James twice. He's friendly, professional, and knowledgeable about a variety of engineering concerns. His inspections have been systematic and thorough. On the inspection he did several years ago for us, he identified several items of concern and mechanical systems that were nearing the end of their service life; pretty much everything he predicted would fail soon has, and everything he identified as being totally fine has been in fact totally fine. What more could you ask for?"

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.

Radon Detection and Reduction questions, answered by experts

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

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.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.
