Why is the floor over my crawl space so cold?
Crawl space insulation in Lakeville keeps the cold under your house from pulling heat out of the floors above. When we seal the crawl space, the insulation goes on its outside walls instead of under the floor, so the space stays closer to the temperature of the rest of your house.
Most people call us because the floor over the crawl space is cold enough to notice in socks, or because a pipe down there froze once and they don't want it to happen again. The price mostly comes down to how big the space is, whether we seal it or leave it vented, what has to be fixed before any insulation goes in and whether a furnace or water heater sits down there. The schedule usually turns on those repairs and on whether the job needs a permit, and the estimate lists each step on its own line so you can see where your money goes.
How we handle crawl space insulation
The first thing I go over with you is whether to seal the crawl space and insulate its walls or keep it vented and insulate under the floor, because that choice decides how warm your floors get and whether your pipes sit in warm air or cold. When pipes or ductwork run down there, I usually lean toward sealing, since that's where the warmth does the most good. On a sealed job, our crew lays heavy plastic over the dirt and seals it to the walls so ground moisture stays below, then insulates the walls and closes the vents. A sealed space still needs a way to dry out, and a little air from your heating system is often one of the best ways to give it one, so we talk through how yours will. Where foam goes in, codes usually call for a covering such as drywall over it, because some foam can give off harmful gases if it gets hot. If your furnace or water heater is down there, we plan a safety check once the sealing is done to make sure the exhaust goes up and out instead of spilling back into the space.
Cold floors don't always start in the crawl space, so I'll also tell you if wall insulation or air sealing services for the gaps around the rest of the house would do more for your comfort than another layer down below.
Crawl space insulation in Lakeville: permits and what we find
Whether your crawl space job needs a permit is up to Lakeville Building Inspections, which issues permits for building, changing or repairing a house and posts a list of work that's exempt. When a job calls for a permit, we pull it, sign for it and set up the inspections, and if we're unsure whether yours does, we check with the city before we start.
Minnesota's energy code lists R-15, the rating for how well insulation slows heat, for crawl space walls, so it's fair to ask me how our plan for your house compares. We're based in Lakeville and work in many of the cities around it, and a lot of the houses we see have pipes or ductwork running through a crawl space that gets cold enough in a hard winter to worry about. We run into the same setup on jobs in Farmington and Prior Lake, and if your city isn't on our list, call and ask.

Call or send a message
Call (651) 268-6023 or use the form and tell us what you're noticing upstairs, like cold floors or a pipe that froze. We'll set a time for me to come out.
I check the crawl space first
I go down into the crawl space to look for water coming in, damp spots or pest damage, and I answer whatever you want to ask. You get a written estimate with each step on its own line, and if something like a leak has to be fixed first, I tell you before we schedule.
Our installers do the work
Our installers work in the order the estimate lists, so nothing gets covered up before it's fixed. They clean up the crawl space and the path in and out when they're done.
We walk through it together
Once the work is done, I go over it with you, down in the crawl space if you want to see it for yourself. It's a good time to ask anything you didn't think of at the estimate.

I come out and explain it
I come out myself to look at your crawl space and write the estimate, and our installers do the work from that same plan. I sold insulation for years before I installed it, so I know how easy it is to push the bigger job, and I'd rather tell you when keeping it vented is enough.
We're licensed and insured
Minnesota requires a license for residential contractors who improve a house using more than one kind of skill, so it's worth asking anyone you're thinking of hiring. We're licensed and insured, and I'm glad to talk it through before you decide.

We've been doing this work since 2017, and we're best known for explaining what's going on in a house before we touch it. If something I said at the estimate didn't make sense, ask again, and I'll keep at it until it does.
If you'd like someone to go down there and tell you plainly what your crawl space needs, request an estimate or call (651) 268-6023.

Questions about crawl space insulation in Lakeville
Is a sealed crawl space better than a vented one in Minnesota?
Compared with a vented crawl space, a sealed and insulated one usually stays drier, because closing the vents cuts down on humid outside air condensing on the cold floor joists. A sealed space is also less likely to harbor pests. If yours is fine vented, I'll say so at the estimate.
How much does crawl space insulation cost in Lakeville?
Insulating a crawl space in the Minneapolis area usually costs about $1,700 to $7,700 per job. That's the going range around here, not our quote, and your own estimate shows each step on its own line so you can see where your job falls.
Who handles the permit for crawl space insulation in Lakeville?
We do. If your job needs a permit from the city, we pull it and set up the inspections, so the paperwork isn't something you have to chase.
What happens before insulation goes in a crawl space?
The crawl space gets checked first for water coming in, damp spots and pest damage, so those get fixed instead of covered up. National guidance also suggests testing your home for radon before an insulating project, and if a radon system turns out to be needed, its vent pipe goes in before the crawl space floor is insulated.
How do I keep pipes in my crawl space from freezing?
Insulating the crawl space helps, because it keeps the space and the floors above warmer, which helps protect pipes and heating equipment down there from freezing temperatures. That matters most when the pipes or furnace run through the crawl space, and heating equipment in a sealed space also tends to last longer and run more efficiently.
What causes cold floors over a crawl space?
Usually it's cold outside air getting into the crawl space through vents and gaps and drawing heat out of the floor above. Bare framing where the house sits on the foundation and open gaps around pipes make it worse, which is why sealing those gaps matters as much as the insulation.
Other work that helps a cold house
Wall insulation
If a room still feels chilly once the floor is warm, the outside walls are often the next place heat slips out.
Air sealing services
Closing drafts around outlets, pipes and the attic hatch can do more for a cold house than adding material.
