"They had a great group of people to work with, The crew was there at the appointment time. Nick and his team worked together well to get the job done, including adding insulation to the attic, adding foam to all exterior walls, and insulating in the basement. This was all done in 1 day and they cleaned up after themselves. I would highly recommend them."

"My attic had many issues. Most guys that bid the job were only interested in blowing the insulation. Great Lakes wanted to correct all the issues first before blowing the insulation. Great group of guys. Very respectful about wearing masks in my home. I would recommend them to anybody!"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

A major mistake during insulation service is ignoring vapor barrier requirements, which leads to severe condensation in Manitowoc’s humid climate. Homeowners also frequently underestimate the high R-values required for harsh WI winters or skip crucial air sealing steps, resulting in damaging ice dams. Additionally, never insulate over active knob-and-tube wiring in historic homes, and always secure the proper local building permits before starting structural work to protect your property.

Helpful?

Address insulation service immediately if you notice moisture, recurring ice dams, or spiking heating bills during harsh WI winters. Homes built before 1980 with older materials or exposed pipes in freezing crawl spaces also require urgent attention. If your current setup functions adequately and you just want an upgrade, schedule the work for late summer or early fall. This timing avoids summer humidity and winter installation complications in Manitowoc.

Helpful?

When hiring for insulation service, you must verify that your contractor holds a valid state license. Look for professionals experienced with Manitowoc’s humid, lake-effect climate and freeze-thaw cycles, as they understand how to manage moisture vapor barriers. Ask about their familiarity with state energy rebate programs, which offer incentives for qualifying upgrades. Finally, check local references to ensure they have a proven track record working on older homes in your area.

Helpful?

You should absolutely combine insulation service with air sealing to meet Wisconsin energy standards and maximize efficiency. If you plan to replace your HVAC system, insulate first so your contractor sizes the new furnace correctly for your improved home envelope. In older Manitowoc homes, you must also remediate active knob-and-tube wiring before adding insulation to prevent fire hazards. Finally, always pair crawl space insulation with a new vapor barrier.

Helpful?

After completing insulation service, perform an annual visual inspection of your attic and crawl space. Look for moisture intrusion, compression, or water damage, especially after heavy Manitowoc snowstorms or ice dam events. Check for rodent activity, as pests frequently nest in blown-in materials. Inspect your crawl space vapor barrier every two to three years for tears or standing water. Finally, monitor state energy programs for updated standards and future rebate opportunities.
