"Ryan, Miguel, Luis and staff did a great job removing old insulation, inspect, clean & disinfect, spray foam, and blow in new insulation. They were efficient, kept me informed, cleaned up well, and addressed minor issues after the completion was complete. I had planned to also spray foam the basement, but we could not vacate the house (fumes) with a member in hospice. This will be done as soon as we are able. Highly recommended!"

"Ryan did our estimate, and was very efficient. Andrew and Evan did the insultation work and did a fantastic job! It was a large area to get prepped and then to insulate and they did a great job every step of the way! Our entire home is now at a R50+ insulation level, as opposed to the R25-30 and 0 values we had before. It will be interesting to see what sort of impact the newly insulated garage and 3 season porch has on the comfort level in the main house. The team did a great job for us and I would recommend them to anyone considering insulation!"

"We've had Home Pro America provide service with several projects. After this last one we agreed to share our experience in this review of their work. We had an issue with ice dams, and had Home Pro out, their recommendations for air sealing, insulation and ventilation were a little more than we were planning to spend. We had another contractor out and for the attic air sealing, they recommended all the existing insulation be removed to seal the attic. We ended up hiring Home Pro and saved more than $1,000. We've since had our roof done and gutter covers installed. We would highly recommend Home Pro America."

"Carl was very prompt with calling me back and actually arranged to fit me in a day earlier than planned. The work was all completed within a couple hours. I guess I expected the spackling to be all set to repaint over, but that will require some touch-ups before painting. Overall, great experience and we will use Specialty Insulators again when we require this type of project."

FAQs for insulation service projects in Lonsdale, 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.
