Is air sealing what my drafty house needs?
Air sealing services in Lakeville close the gaps where outside air gets into your house, mostly through the attic floor, so the heat you pay for stays in your rooms. Insulation is like a sweater, warm but not windproof, and sealing is the windbreaker that goes over it.
If your upstairs runs hot, the floors stay cold or the power bill keeps climbing, the air is usually slipping through gaps in the attic floor that you can't see under the insulation. What moves the price is how many of those gaps there are and how much insulation has to be moved to reach them, and the schedule mostly turns on whether something like a roof leak has to be fixed first. If you're planning to add attic insulation, the openings in the attic floor should be sealed first, so we make sealing the first step of that same job, and the estimate shows each step on its own line.
What our air sealing service covers
Before we seal anything, we test the house, because if your furnace or water heater has trouble getting its exhaust out, a tighter house makes that worse, so any venting problem gets fixed before sealing starts. Then our installers pull back or scoop out the attic insulation where they need to and seal what's underneath, which means the joints where your walls meet the attic floor, the chases where ducts and plumbing run up through the house, dropped ceilings like the boxed-in space over kitchen cabinets, and the gaps around kneewalls, the short walls in rooms with sloped ceilings, plus can lights, flue pipes and the hatch. Once those are closed, the insulation goes back or gets topped up, with the eave vents kept clear so the attic can still breathe and the edges filled as deep as the middle.
Foam costs more because it seals and insulates in one pass, and in most attics sealing the gaps and topping up loose fill does the job for less, so that's usually what I'll recommend. When your ductwork runs through the attic, closed-cell foam insulation, a dense foam that also blocks moisture, can be worth the extra cost. Leaks don't stop at the attic either, and if we're sealing where the house sits on the foundation, it often makes sense to do the basement insulation at the same visit.
What changes air sealing work in Lakeville
The city requires a permit to alter or repair a building and wants questions taken to Lakeville Building Inspections before work starts. Whether a given sealing job needs one isn't always clear, so when I'm not sure about yours, I check with them before we begin, and when a job does need a permit, we pull it, sign for it and set up the inspections.
We're based in Lakeville and work in many of the cities around it, and the attics look a lot alike from one to the next, with a room over the garage, can lights in the top-floor ceilings and a hatch in a closet or hallway. We see the same leaks on jobs in Farmington and Apple Valley, and a long Minnesota winter is what turns them into cold floors and a high power bill. If your city isn't on our list, call and ask.

I look and write it up
I go up into the attic, look at the hatch, the lights and the vents, and answer your questions as we go. You get a written estimate with each step on its own line, and if something like a roof leak or water coming in has to be fixed first, I tell you before we schedule.
Our installers seal the attic
Our installers move the insulation aside where they need to, seal the gaps underneath and put it back or top it up. You're welcome to ask them anything while they're there.
We walk through it together

Why Lakeville homeowners call Quality Lakeville Insulation Services for air sealing
The owner writes your estimate
I come out myself to look at the attic, answer your questions and write the estimate, and our installers do the work after that. When they're finished, I check it with you, so the person who explained the job is the one who looks it over.
Told straight when foam isn't needed
I sold insulation for a few years before I learned the trade and started this business in Lakeville in 2017, so I know how easy it is to push the bigger job. If your attic needs sealing more than it needs foam, that's what I'll tell you.
A licence worth asking about
Minnesota requires a residential building contractor or residential remodeler license from any company you hire directly for work that covers more than one special skill on a house with one to four units, so it's fair to ask anyone who bids. We're licensed and insured.
What matters most here is finding the leaks under the insulation, not just piling more on top. Set up a visit and I'll show you where yours are.

Questions about air sealing in Lakeville
How do I seal air leaks in my house myself?
You can caulk the obvious ones yourself, like gaps around door frames and where pipes, vents, wires, ducts and fans pass through outside walls. The small, hard-to-find leaks are another story, especially in the attic under the insulation, and that's where hiring help pays off. When I'm out for the estimate, I'll show you which ones you can handle.
How much does attic air sealing cost in Lakeville, MN?
Attic insulation and air sealing together in Minnesota usually costs about $1,000 to $4,500 per project, and most quotes Minnesota energy advisors review land in the middle of that range. Where your house falls depends on how much work it needs, mostly how many gaps there are and how much insulation has to come up and go back. That's the usual price for the combined job across the state, not our price, and your estimate breaks out the figure for your house.
Is there help paying for air sealing in Dakota County?
Yes, if your household qualifies, the Dakota County Community Development Agency's Weatherization Assistance Program uses grant money to reduce air leakage and insulate attics or walls at no cost to you. Their energy specialist does an audit, and the agency picks a qualified contractor and inspects the work, so it may not be us who does the job.
Will air sealing help with ice dams on my roof?
Yes, sealing and insulating the attic is the best way to prevent ice dams and the damage they do to a house. Warm air leaking up through the attic floor warms the roof, so the snow melts and then refreezes at the cold edge.
Do I need to remove old insulation before air sealing my attic?
Only if it's wet or full of droppings, because fresh material on top of it leaves the problem in place. Dry, clean insulation can usually be moved aside, sealed under and put back. If yours has to come out, that's insulation removal, and it shows up as its own line on the estimate.
How do I know if air sealing worked?
The surest way is a blower door test after the work, where a big fan in a doorway measures how much leakage is left and shows whether the house needs mechanical ventilation. Ask whoever seals your house whether it will be retested, and I'll go over that with you at the estimate.
Other work that pairs with air sealing
Basement insulation
Helps with cold floors and a chilly lower level once the gaps where the house meets the foundation are closed.
Closed-cell foam insulation
Worth a look when ducts run through the attic or a spot needs insulation and a moisture block in one layer.
