Do my walls need insulation, and what does it take?
Wall insulation in Lakeville fills the empty spaces inside your exterior walls so the house holds its heat better, and with some methods it seals air leaks at the same time.
Most people call because one room never warms up, the outside walls feel cold to the touch, or the power bill climbs every winter. If the cold seems to come from above, attic insulation may be the better place to start, and I'll tell you that. The price mostly turns on how much wall we're filling, whether the walls are closed or already open, and what's on the outside, since patching siding takes more care than patching drywall. The schedule turns on whether anything needs fixing before we insulate and whether you've got a remodel coming, and your estimate lists each step on its own line so you can see where the money goes.
How we handle wall insulation
I start by looking at the walls you're worried about, inside and out, and checking what's already in them, because some walls are empty and some just hold a thin layer that's settled over the years. For closed walls, we talk through whether to drill from inside or outside and how the holes get patched to match your siding or plaster, since that patch is the part you'll be looking at for a long time. Then our installers fill the cavities, finish the holes and clean up after themselves. If you've got a remodel coming on those walls, I'll tell you to wait and do it then, because open walls are the cheapest time to add insulation.
Walls are only part of why a room feels drafty, so air sealing services often go along with filling them, closing the gaps where cold air slips in around trim, outlets and the spot where the house meets the foundation. If the cold rooms are downstairs, basement insulation on the foundation walls may do more for you than anything above ground.
Wall insulation in Lakeville: permits and hiring
Lakeville's rules don't say outright whether adding wall insulation needs a permit. The city's Building Inspections office handles permits to alter or repair a house, and its list of work that needs no permit names things like wallpaper, paneling and redecorating that doesn't touch the structure, and insulation isn't on it. The city asks anyone who isn't sure to call that office before work starts, so I check with them before we begin, and if your job needs a permit, we pull it, sign for it and set up the inspections. Hiring matters here too, because Minnesota requires a license for contractors who take on home improvement work for a homeowner that calls for more than one skilled trade.
Most wall calls we get around Lakeville start with one room that won't warm up, often a corner bedroom or the room over the garage. Older houses tend to have plaster inside and wood siding or brick outside, while newer ones have drywall and vinyl, and that mix decides how we drill and patch. We see the same kinds of houses on jobs in Apple Valley and Farmington, and if your city isn't on our list, call and ask.

I look at your walls
I check the walls inside and out and answer whatever you want to ask, as many times as you want to ask it. You get a written estimate with each step on its own line, so you know what every part costs before you decide.
Fix what has to come first
If I find something that has to be fixed first, like a roof leak or water getting into a wall, I tell you before we put you on the schedule. That way you're not paying to insulate a wall that has to be opened again.

Why Lakeville homeowners call Quality Lakeville Insulation Services about their walls
Licensed and insured for your job
We're licensed and insured for the work we do in your house. Lakeville checks the contractor's license on every permit application, so if a contractor asks you to apply for the permit yourself, they likely aren't licensed.
A former salesman who won't upsell
I sold insulation before I installed it, then learned the trade in attics, basements and crawl spaces and started this business in 2017. Having sold it, I know how easy it is to push the bigger job, so I'll tell you when your house needs less than you expected.
Questions answered, early or late
We pick up from 7 AM to 10 PM on weekdays and 6 AM to 11 PM on weekends, so you can call after work or before the kids are up. I'll stay on the line until you're out of questions, even if it's the same one twice.
If one room in your house never warms up, the walls are worth a look before you spend anything. Send us a message or call (651) 268-6023, and I'll come out and take a look.

Questions about wall insulation in Lakeville
How do I tell if my older home has insulated walls?
Often they aren't, since houses built before 1960 usually have no wall insulation or an older product that falls short of today's, and some newer homes were never fully filled either. For a quick look, turn off the power, take the cover off an outlet or switch on an outside wall and shine a flashlight beside the electrical box, though that only shows whether anything is in there. Only an energy assessment with infrared imaging shows how well the insulation was put in, and adding more is usually worth it when the walls hold less than an inch or the imaging shows big gaps.
What is the best way to insulate existing walls without tearing them open?
For closed walls, the usual method is to drill small holes from inside or outside and blow in dense-pack cellulose, loose fiber packed tight into each cavity, which insulates well and seals a lot of air leaks. The holes then have to be patched and finished, and that's harder on siding than on drywall, so ask any contractor exactly how they'll do it.
How much does wall insulation cost in Lakeville?
Blown-in insulation in the Minneapolis area usually runs about $2 to $8.50 per square foot, and that's the going range for blown-in work, not our price. Where your house lands depends on how much wall we're filling, how much work the patching takes, and whether any repairs come first. Your estimate shows your own number, one step at a time.
Who should sign the building permit for insulation work in Lakeville?
Your contractor should sign it, because in Lakeville the contractor who signs agrees to do the work to code, while a homeowner who signs becomes liable for correcting the contractor's work. That's why we sign for ours whenever a job needs one.
Do walls need to be dry before you add insulation?
Yes, any moisture problem has to be found and fixed first. Federal guidance for existing homes says to check walls for moisture or other damage and hold off on insulating until problems in the siding, the sheathing boards behind it, the window and door framing or the inside finish are repaired. A damp wall moves repair work ahead of insulation on the schedule.
Can I use fiberglass batts if my walls are already open?
Yes, batts work well in open walls as long as they're cut carefully around wires, electrical boxes, pipes and vents. A batt that gets squeezed or bunched up loses insulating value and leaves gaps. With batts, a vapor retarder goes over the insulation to slow moisture moving into the wall, and every seam gets sealed with sheathing tape.
