What does attic air sealing do for a drafty Lakeville house?
Attic air sealing in Lakeville closes the gaps in your attic floor around wires, pipes, ducts and vents, and along the tops of the walls below, so warm air stops leaking out of your rooms and the drafts ease up.
Most people call us about a cold upstairs bedroom, a heating bill that keeps climbing or ice along the roof edge, and when they peek through the hatch the insulation looks fine. The trouble is usually warm air slipping past it through holes in the ceiling, so piling on more attic insulation won't fix it until those holes are closed. The price moves with how many gaps there are, how tight the attic is to crawl around in and whether old insulation that got wet or full of droppings has to come out first, and the schedule moves with anything that needs fixing before we can start, like a roof leak. Your estimate gives you the number for your own house.
How our crew does attic air sealing
Before we seal anything, I check that your attic is ready for it, which means no roof leak, no bath fan blowing into the attic and no old knob and tube wiring that's still live, because sealing over any of those locks a problem in. Once it's ready, our installers pull back the insulation where the gaps are, around wires, pipes, ducts, can lights and the hatch, and along the tops of the walls below. Small cracks get caulk and bigger holes get expanding foam, and we keep the vents at the eaves clear so the attic can still breathe. Then the insulation goes back down evenly, full at the edges instead of piled up in the middle, and we clean up before we leave.
Sealing is often the first half of a bigger job. If your house is older and never had much insulation, retrofit insulation adds to it once the gaps are closed. Spray foam insulation seals and insulates in one pass, but it costs more, and in most attics sealing the gaps and topping up the loose fill does the job for less. Foam starts to make sense when your ductwork runs through the attic.
Attic air sealing in Lakeville, permits and ice dams
We don't guess about permits. The state building code and the city both require a permit to alter or repair a building, and Lakeville's Building Inspections office answers permit questions before work starts, so if we're not sure about your job, we ask them first. When a permit is needed, we pull it, sign for it and set up the inspections.
Ice dams are how a lot of Lakeville homeowners first hear about air sealing. Warm, moist air leaking into the attic melts the snow on the roof from underneath, and the water refreezes when it runs down to the cold eaves, so the gaps we close are the same ones feeding that ice. We see the same thing on jobs in Apple Valley and Farmington, since we're based in Lakeville and work in many of the cities around it. If your city isn't on our list, call and ask.

Questions about attic air sealing in Lakeville
How much does attic air sealing cost in Minnesota?
Attic insulation and air sealing projects in Minnesota usually cost about $1,000 to $4,500 per job, and that range covers the two pieces of work together. Where yours lands depends on how much work the attic needs, and most quotes reviewed by Minnesota energy advisors fall in the middle of that range. Your line-by-line estimate shows where your house falls.
How do I know if my attic is ready for air sealing?
Your attic is ready when nothing up there needs fixing first, and a national attic sealing guide says to hold off if you have active knob and tube wiring, vermiculite insulation, the pebbly gray-brown kind, or bath fans venting into the attic. The same goes for a leaking roof or an unvented kerosene heater or gas fireplace in the house. If any of those turn up when I look, I'll tell you and we'll sort it out before sealing.
Will air sealing stop ice dams on my house?
It usually cuts them down a lot, because it keeps the warm air that melts roof snow out of the attic, but it may not end them on every house. Story-and-a-half homes are the hard case since the ceiling sits so close to the roof, and sealing and insulating where we can helps a great deal there without promising an ice-free roof. If yours is one of those, I'll say so up front.
Should I seal my attic before adding insulation?
Yes, seal first, and Minnesota's Commerce Department says sealing air leaks has to be part of any insulation job. The department also says pairing the two can cut your heating and cooling costs, so it makes sense to plan them as one project.
How do I find out where my attic is leaking?
The state recommends an energy assessment with a blower-door test, which pulls air out of the house to measure how leaky it is, and infrared scans that show where the leaks are. That kind of assessment also checks that your furnace and other gas appliances are working safely. Home Energy Squad visits are open to any Minnesota resident with a CenterPoint Energy or Xcel Energy account.
Can I get an Xcel Energy rebate for attic air sealing?
Xcel Energy's rebate requires that a participating contractor complete all of the insulation and air sealing work. Check that with any contractor before you sign, and mention your utility when you call so we can talk it through.
