"Exactly as the same as the first time I air sealed my attic in my previous house. Last year when we decided to sell our house I was inspecting my house as I would have if I was purchasing it. I noticed a small (1/4") gap between the master bathroom vent fan grill and the ceiling. I could not adjust it. Upon further inspection I realize it was because the foam that was installed when my attic was air sealed had expanded creating the 1/4" gap. I had that work done two years prior by Houle Insulation. I contacted Arne and inquired if he had any suggestions. His only suggestion was that he would correct the problem. Two days later he had two workers in my attic correcting the issue. Just like the first time, they were prompt and cleaned up after the work. I offered to pay, he would not have it. He said he should have noticed when the job was originally completed two years prior. There was no discussion or haggling, he simply said he would correct it. As impressed as I was with the lower energy bill, I was more impressed with how he and his team comported themselves. Also my house was more comfortable because the temperature was more uniform within my house. This year when we moved into our new house, built in 1992, the first thing I did was call Arne to air seal the attic. My choice of whom to hire for air sealing my attic was a no brainer, Houle Insulation. They also performed a blower door test. They also sent in all the information required for me to receive an energy rebate from my utility company. The best recommendation I can make is that when I decided to air seal our new home the first person I called was Arne. He made a wise decision to correct what needed with correcting without any questions. He did what should have been done, and therefore he got my repeat business and I was happy to give my business to him!"

"One of the most enjoyable interactions I've had with a contractor. Mike and Maurice where professional and personable. On time with quality workmanship during the project. Really appreciate my first encounter with Mike during his first visit for a quote as there was no high-pressure sales tactics (i.e. quote only good for today). Project was weatherization and re-insulation of the attic. They told me exactly what they were doing and why and answered any question I had. I'd had friends tell me when they had this done it was messy...not so with MnM as they cleaned up very nicely when the job was finished. I'd have no problem recommending them to family/friends who were looking for the same type of project."

"I was really impressed with the whole team at Guevara Insulation. They worked efficiently, the quality, and attention to detail was top notch. As a builder, and remodeler I've worked with many tradesmen over the years. So I can tell when guys really care about what they do, and it shows in their work. I had them work on my personal home build. They spray foamed all the exterior walls, and joist pockets, installed fiberglass batts, poly'd and caulked all framing seams. Then came back to finish the blow in once the drywall was up. I'll definitely be using them on my future projects, and will be recommending them to anyone needing insulation work done."

Insulation questions, answered by experts

Upgrading insulation in Plymouth can make your home more attractive to buyers by improving energy efficiency and comfort. Documented improvements, such as an energy audit or upgraded attic insulation, often lead to faster sales and higher offers. Features like reduced utility bills and better indoor air quality are highly valued in the local market, helping your home stand out among other listings.

Helpful?

Insulation upgrades in Plymouth deliver immediate comfort with fewer drafts and more consistent indoor temperatures. Over time, you’ll notice lower energy bills, improved indoor air quality, and less strain on your HVAC system. Enhanced attic insulation also helps prevent ice dams and moisture issues common in the area, supporting a healthier home and contributing to Plymouth’s sustainability efforts for years to come.

Helpful?

Before starting insulation work in Plymouth, check if a permit is needed and confirm your plans align with MN energy code standards. Schedule an energy audit to identify problem areas, and test for asbestos in older homes. Clear out storage from attics or crawl spaces, protect valuables, and document current conditions. Planning around weather and applying early for utility rebates can help your project stay on track.

Helpful?

When hiring insulation pros in MN, prioritize those with strong insurance, local experience, and positive reviews from nearby homeowners. Ensure they are familiar with state energy codes and rebate programs, and ask about their approach to attic insulation and moisture control. Request detailed quotes, check for manufacturer certifications, and look for a transparent process—avoid anyone unwilling to provide local references or who pressures you to decide quickly.

Helpful?

In Plymouth, start by sealing small gaps around windows and doors with weather-resistant caulk and adding foam gaskets behind outlet covers to reduce drafts. Always wear gloves and an N95 mask, especially in older homes, and work in well-ventilated areas. If you notice signs of moisture, electrical wiring, or possible asbestos, stop and contact a local insulation pro for safe attic insulation or air sealing solutions.
