"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."

"Very good - other than when we asked for the fans to be removed, they left all the electric cords connecting them to the outlet outside of the crawl space."

"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."

"We needed to replace the siding on our home, had four companies come to our house (three of which were initially found through Angi), and are glad that we used Hoffman Weber to do the job. Their sales associate (Al Lien) was knowledgeable and helpful, but no pressure, which I personally appreciate very much. They had a range of options, and in the end we chose to use HardiPlank which was less expensive than LP at the time of our project. The Hoffman Weber price was very competitive (and significantly lower than the high-pressure company that came out). The installation went well--the crew was hard working and pleasant, and communication with the project manager (Pete) was easy (the installation was done in February, so, weather affected the days of installation). The finished project looks great."

"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.

FAQs for insulation service 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.
