Our Home Insulation Services
Home Insulation Services in Chicago That Save You Energy Costs
A home that will not stay comfortable is often losing energy through more than one area. Poor attic insulation, unsealed gaps, exposed rim joists, and under-insulated crawl spaces can all contribute to drafts, cold floors, hot upstairs rooms, and heating or cooling systems that seem to run constantly.
We help homeowners throughout Chicago and the surrounding suburbs find those weak points and correct them with the insulation system that fits the area of the home. Our services include blown-in fiberglass attic insulation, air sealing, spray foam rim joist insulation, rigid foam crawl-space insulation, and blower door testing.
Find Out Where Your Home Is Losing Comfort
A More Comfortable Home Starts With the Right Diagnosis
Adding insulation without understanding the problem can leave important gaps untreated. A home may have thin attic insulation, air leaks below the existing insulation, an exposed rim joist, or poorly insulated crawl-space walls. In many homes, more than one of these conditions is contributing to the comfort problem.
We start by looking at the areas connected to what you are experiencing in your home. From there, we can recommend the insulation and air-sealing work that fits the problem instead of applying the same material everywhere.
Where Is Your Home Losing Comfort?
Insulation problems do not always look the same from one house to another. One homeowner may notice a second floor that becomes difficult to cool every summer, while another may have cold first-floor rooms because of conditions around the basement or crawl space.
Some of the common reasons homeowners contact us include:
- Hot or cold rooms that never seem to match the thermostat
- Cold floors during Chicago winters
- Drafts around floors, walls, or other areas of the home
- An upstairs that becomes noticeably hotter in summer
- Old, thin, uneven, or deteriorated attic insulation
- Heating and cooling costs that seem high for the home
- Concerns about how much air is leaking through the house
An inspection helps us connect those symptoms to the areas that actually need attention
Benefits of Upgrading Your insulation
Improved Home Comfort:
Upgraded insulation ensures a consistent indoor temperature, eliminating winter cold drafts and summer excess heat. Enjoy a more comfortable living space year-round.
Energy Efficiency and Cost Savings:
Proper insulation reduces the strain on your heating and cooling systems, leading to lower energy consumption and significant cost savings on utility bills.
Ice Dam Prevention:
Proper attic insulation is one of the most effective ways to prevent ice dams from forming on your roof.
Better HVAC Performance:
In most cases, the reason your home does not stay at the temperature you set is not because of a faulty HVAC system. Poor insulation is the primary cause of conditioned air loss and can lead to temperature fluctuations throughout your home.

Dave S. went above and beyond when
we had called Permaseal out for an attic insulation inquiry. Out by of the 5
companies we called, he was the most
thorough in explaining the process. David B. Came out after the job to redo the efficiency test and compare it to what our reading was prior to new insulation. Our efficiency reading significantly increased. The insulation install team was awesome too! They contained the surrounding area prior to removing old insulation..
Emily G.
Fantastic experience from start to finish! Oren was a terrific resource and made everything easy to follow and transparent! We knew we made the right decision after his thorough observation of our attics and crawl space. The team came out and were efficient, clean, friendly, and did all work as promised. We highly recommend working with Permaseal especially for your insulation needs!

Oren came to give me a free estimate on attic insulation. He arrived around 1 which worked out perfectly. He explained what their insulation entailed and how they seal all air gaps. He was very knowledgeable, personable and engaging. I decided to have them do the job and it was scheduled for the very next day. Oren also made 3 calls to ensure the financing was secured before he left. I’m looking forward to lower energy costs. Thanks Oren.

We Remove Old Attic Insulation Before Starting Over
Our attic insulation process does not involve simply adding another layer over what is already there. We remove the existing insulation first so we can expose the attic floor and reach accessible air leaks that may have been covered for years.
Once the old insulation is removed, we seal accessible gaps and penetrations with spray or expanding foam. New blown-in fiberglass insulation is then installed across the attic. Fiberglass batts may occasionally be used where they make sense for the structure, but blown-in fiberglass is our primary attic insulation system.
This process allows us to address air leakage and insulation as two parts of the same attic project instead of covering existing problems with more insulation.
Why Upgrade Your Insulation?
A well-insulated home stays comfortable through Chicago’s hottest summers and coldest winters. Perma-Seal’s insulation experts make it easy to improve efficiency fast with solutions tailored to your attic, crawl space, or basement, starting with a free, no-pressure estimate.
Lower Energy Bills
Upgraded insulation reduces heat loss in winter and heat gain in summer, so your HVAC system doesn’t have to work overtime. The result is steadier indoor temps and noticeable savings on monthly utility costs.
Quieter & Cleaner Spaces
Insulation helps dampen outside noise and seals the gaps that let drafts and pests sneak in. It’s a simple upgrade that makes your home feel calmer, tighter, and more protected.
Healthier Indoor Air
Proper insulation and air sealing limit the flow of outdoor dust, allergens, and pollutants into your home. It also helps control humidity levels, reducing the conditions that can lead to musty mells or mold growth.
