"We hired USA Insulation of Madison to spray foam insulation in our exterior walls.  Boy what a difference  it made.  Not only did it sound proof our home from outside noises but our home seems more balanced as far as being cool.  I can only imagine how it will be this winter.  I dealt with Emily and she was just a sweetheart.  She worked with us to coordinate a perfect time for their guys to come out.  She was always available to answer any questions that I had.  A few days after the job was done, she called to make sure that we were satisfied with the work, and we were.  Jeff, too, was very personal and professional.  There were three young men that did the foam spraying.  They were very courteous and worked hard to get the job done in just 1 day.  They put all the siding back in place and cleaned up around my landscaping.  I would definitely recommend this business due to the great product and friendly, polite and professional people."

FAQs for spray foam insulation projects in Platteville, WI

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.
