"We really needed some insulation since we could tell we didnâ t have much protection. Now we have plenty of protection and we are happy. The crew came in, set up, and worked quite well together. They did an excellent job. We highly recommend Northstar for their work and their pricing."

"I recently had the pleasure of working with Wichita Spray Foam Solutions, and I couldn’t be more impressed with the results. From start to finish, the team at Wichita Spray Foam Solutions was incredibly professional and knowledgeable. They took the time to explain the differences between closed cell spray foam, fiberglass, and cellulose, and helped me choose the best option for my specific needs. We had spray foam insulation installed in our attic insulation space as well as in a warehouse and a barndominium, and the quality of the work was outstanding. You can immediately tell they focus on high quality materials and craftsmanship. Their expertise in both residential insulation and commercial insulation really shows. The closed cell spray foam they installed has already made a noticeable difference in how energy efficient our buildings feel. We are expecting a lower utility bill thanks to the improved sealing and insulation performance. Everything was completed at a fair price, and"

"First off the job I was wanting done was a small job. I installed a window in the mud room and when I removed the paneling in the wall to cut the hole for the window, I found unexpected voids in the wall from the previous work. I also put up a stud wall in the west of the mud room. My original plan was to fully insulate with foam the mud room because it was the only room in the house left exposed to outside temperature changes. I expected to pay fully for the work.
Chris, owner and president of Air Tight, came over to give me a proper estimate for the work I wanted done. I showed Chris all that I wanted done from the garage end first and then I showed him the wall with the newly installed window. He noticed the voids in the wall and was surprised because his company "does not do substandard work," as Chris put it. I was prepared to pay for the new work I wanted done, but he told me Air Tight of Kansas would do it for free.
Air Tight of Kansas stands behind their work more than a 100%. I could not be happier with the insulation. The house stays  warmer in the winter and cooler in the summer with the new heating and cooling system without sky high bills. There is no more creaking or popping with the change in temperature any longer. As an added bonus to the foam insulation, there is less movement do to strong winds, one can hardly hear the wind or rain for that matter.
The employees are excited about their product and that excitement I picked up on at the Home Show, where I was introduced to foam installation as a retrofit option. The cost was reasonable and I expect to pay less in gas and electricity for heating and cooling over the next few years.
I highly recommend Air Tight of Kansas for new construction and remodeling for your insulation needs.

Insulation FAQs, answered by experts

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.
