"We called Home Seal to consult on weatherization and insulation for our 1920s bungalow. The advice was great and we hired them to insulate the rim joists between our basement and first floor as well as adding cellulose insulation to our attic space. The communication throughout this project went well and the work was completed as scheduled. We would highly recommend Home Seal for weatherization and insulation projects."

"Their guys were on time, professional, and communicated exactly what they were going to do as well as how long it would take them They finished what I was sure would be a 2 day job in a single day which was very convenient,. The foam applicator explained the technical aspects of the requirements for it's application, as well as making it very cosmetically appealing and consisent. They beat several other companies on price and exceeded the service you'd expect from the cheapest bid by a mile. Would hire or recommend them to anybody for any and all insulation needs."

"Mark was very prompt with the inspection and bid, and was able to get right to work.  He sized up my situation expertly and suggested details that I would have overlooked.  His crew of two were very efficient and finished the job in five hours.  Mark was present for the start and finish of the job.  He had excellent advice for a future phase of my project, and was open to doing those parts of it that are beyond my expertise.  (In other words, he can work small and not insist on taking the whole job).  Affable guy too, with an enthusiasm for insulation.  Recommended.

"The project went very well. Work started as soon as the city inspector signed off on the permit, and was completed on time. At the end of each day Five Star left the site clean and orderly. They encountered some unexpected hidden problems which they resolved without adding any extra costs to our bill. Paul and Kelly were pleasant to deal with at all times, and we will gladly recommend them. They did quality work, on schedule, and on budget."

FAQs for spray foam insulation projects in Winthrop, MN

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
