Your attic insulation is patchy with bare spots showing between the ceiling joists. The energy bills keep climbing and some rooms never stay comfortable no matter how you adjust the thermostat. Central Insulation Systems Inc. handles blown attic insulation across Ohio, Kentucky, and Indiana.

Blown insulation works in attics built from the 1970s forward where you have open joist bays between the ceiling and roof. You'll see it as loose-fill material that looks like shredded paper or cotton batting spread between the wooden beams. If your house was built before 1980, the original insulation may have settled to half its thickness or blown into corners leaving bare patches.

Thin insulation means your HVAC system runs constantly trying to keep up. Hot air rises through gaps in summer and cold air sinks through in winter. Your energy bills stay high year-round and upstairs rooms are always too hot or too cold compared to the main floor.

Central Insulation Systems Inc. clears pathways through your stored items and seals air leaks around pipes and electrical fixtures first. The crew then blows cellulose or fiberglass insulation to the R-value required by your local building code. New insulation covers every joist bay including the edges where old insulation typically pulls away from exterior walls. Attic access restoration and cleanup are included in the work.

Your house will hold temperature better once the attic has proper insulation coverage. The HVAC system won't cycle as often and upstairs rooms will stay comfortable. You'll see the difference on your next utility bill.

THEY DID A GOOD JOB AND I THOUGHT THE PRICE WAS REASONABLE.

I worked with Kevin Con, their field specialist. Kevin talked to me over the phone for quite awhile to make sure that I had a good estimate and knowledge of the procedure. The team came out early and they were efficient in the processes. I would highly recommend them especially because they worked so closely with our roofing team to get the job done in one day.

I am just so happy. They came out on a Tuesday (the owner Steve and his son) and took a look and had a crew of 2 out for me the next day! They got there at 8:30 am and all was completed by 2:00. The follow up was excellent. I could just go on and on. I am very impressed and want to insulate everything NOW because they were so excellent!

Common questions

high energy bills need more insulation

Your heating and cooling bills keep going up. Your house feels drafty in winter and hot in summer. You think you need more insulation but don't know where to start.

Start with your attic. Most heat loss happens through the roof. Check if your attic insulation meets current R-value requirements for your climate zone. Add blown-in fiberglass insulation to reach R-38 to R-60 depending on your location.

attic insulation contaminated with rodent droppings

Your attic insulation is contaminated with mouse or rat droppings. It smells terrible and you're worried about disease. You don't know if you can clean it or need to replace it all.

Don't try to clean contaminated insulation yourself. Rodent waste carries serious diseases like hantavirus. The safest approach is complete removal, sanitization of the attic space, and fresh insulation installation to current R-value codes.

blown in attic insulation cost

Your attic has no insulation or very little. You got quotes for blown-in insulation but the prices vary a lot. You want to know what's reasonable.

Blown-in fiberglass costs $1.50-3.00 per square foot installed. Price depends on R-value needed and attic access. For a 1200 sq ft attic, expect $1800-3600 total. Cheaper quotes often mean lower R-value.

house cold high energy bills insulation

Your heating bill doubled this winter. Some rooms are always cold. You can feel drafts but don't know where they're coming from.

Check your attic insulation first. Most heat loss happens through the roof. If you can see floor joists through the insulation, you need more. R-38 to R-60 blown insulation typically pays for itself in 2-3 years.

when to remove old insulation before adding new

Your house has old insulation that might be from the 1970s or 1980s. You don't know if you should remove it before adding new insulation or just add more on top.

Remove old insulation if it's damaged by water, contaminated by pests, or contains asbestos. If it's clean and dry, you can usually add new insulation on top. Get the old material tested first if your house was built before 1980.

attic insulation removal cost

Your attic insulation has been damaged — whether from pests, fire, water, or mold — and you need it removed and replaced. You want to know what it's going to cost before calling someone.

Costs vary depending on the cause and how much insulation is affected, but most jobs require full removal and sanitation before re-insulation. Removal runs $1–2 per sq ft, and replacement adds another $1.50–4 per sq ft depending on insulation type. For a typical 1,000–1,500 sq ft attic, expect to pay $3,000–$10,000 or more when sanitation is involved. Pest or fire damage usually means the most thorough cleanup.

adding insulation to old house worth it

Your house is 20+ years old with little insulation. You're wondering if it's worth upgrading now or if you should have done it when the house was built.

It's never too late to add insulation. Older houses often have the most to gain from upgrades. You can blow insulation into existing walls and add attic insulation anytime. Most projects pay for themselves within 3-5 years.
