"I highly recommend Insulation Inc. They provided a timely and thorough quote for insulating my garage attic. Their team arrived on time and upon completion walked me through their work and provided pictures of areas I could not see. The crew cleaned up after completing the job. The Insulation Inc. crew was professional and delivered quality work."

"These guys are the best. My 100-year old house never had much insulation in the attic and after a problem with ice dams in 2019 I decided to get the attic insulated. Houle was on the list of CenterPoint-approved contractors. They came when they said they would, did the work quickly, explained what they had done and cleaned up. They processed my rebate application for me too. My heating bills noticeably dropped last winter, and now that it is warm my house has stayed cooler longer. This summer, I had some water damage on a bedroom ceiling and wondered if the insulation work had somehow disconnected a pump for the AC unit in the attic. Houle sent techs out the same day to check. It turned out the pump had died on its own. The two techs took the time to do their own investigation of what the problem was, and did so cheerfully. Houle stands by their work and takes customer service seriously. I am impressed."

"Ours was a bathroom remodel. There was a minimum for spray foam, understandably, but because of that they removed some loose insulation that we didn't have the energy to remove! Shaun in particular was super. Troy was a great sales rep and answered any questions I had right away."

"Professional and courteous. The folks on site took time to answer any question, wore masks and cleaned up well. They did great job painting the stucco after insulation and patching - house looks great. The insulation is already making huge difference in my 1911 house in Minneapolis- not sure the boiler will kick in till December."

"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!"

Insulation questions, answered by experts

If your St Paul home has cold spots, drafty rooms, or noticeably uneven temperatures between floors, it may need better insulation. Signs like persistent ice dams, frost buildup in the attic, or chilly floors above basements are common in older St Paul homes. If your heating system runs frequently or your energy bills seem unusually high, it’s a strong indicator to consider insulation service projects.

Helpful?

In St Paul, you’ll find several types of contractors for insulation service projects: full-service insulation specialists, HVAC companies that offer insulation upgrades, general contractors who include insulation in remodels, and energy efficiency consultants who focus on whole-home performance. Many provide energy audits and air sealing. Choosing a contractor with local experience and relevant certifications ensures quality results and access to area-specific rebates.

Helpful?

In St Paul, most attic insulation service projects are completed within 4-8 hours, while wall insulation retrofits usually take 2-3 days for an average home. Insulating basements or crawl spaces typically requires 1-2 days. Whole-house insulation may take 3-5 days. Project length can vary due to weather, home size, or if your property is historic and needs special care.

Helpful?

Insulation in St Paul benefits from regular maintenance, especially after harsh winters. Each spring and fall, check for moisture, gaps, or signs of pest activity in attics and crawl spaces. Blown-in insulation may need to be topped off after several years, while batt insulation should be inspected for shifting or settling. Scheduling periodic energy audits helps identify areas needing attention and keeps your home performing efficiently.

Helpful?

Upgrading insulation in St Paul can make your home more attractive to buyers, especially given the area’s cold winters. Enhanced insulation improves comfort, reduces drafts, and can lower utility bills, which appeals to energy-conscious buyers. Many local buyers look for homes with recent energy efficiency upgrades, so insulation service projects can help your property stand out in the St Paul real estate market.
