Cold floors and drafts from below? We insulate your crawl space in the right order, so the floors warm up and it stays dry.
Crawl space insulation in West Lafayette seals and insulates either the crawl space walls or the floor above it. That sets the line that keeps your house's heat inside and stops the rooms over it from running cold.
Most people call because the floors over the crawl space are cold, a room feels drafty or the power bill doesn't make sense, and underneath I usually find loose batts, open vents and gaps around the pipes. The price moves with how big the space is, whether we're doing the walls or the floor, what equipment sits down there and whether old insulation has to come out first through insulation removal. The schedule turns on the same things, plus how much room there is to crawl and whether your heating and cooling setup is part of the plan, so your own number comes from the estimate once I've seen the space.
I'm the one who comes out, gets under the house with a flashlight and gives you the estimate. I also work alongside our crew on the install, so the person who planned your crawl space is there when the work gets done.
If the crawl space is wet or the old insulation is soaked, I'll say so before we talk about new material, because insulation over a moisture problem is money thrown away. I'd rather tell you a job isn't worth doing than sell it to you.
I left an office job for work I could see at the end of the day, learned insulation on another contractor's crew and started this business in 2023. We're best known for attics and air sealing, the part that makes the insulation count.
We're fully licensed and insured. Satisfaction guaranteed on every job. When you're ready, call (765) 250-8264 or use the form on this page with your address and what's in your crawl space, and I'll come out and take a look.
Tell us your address, about how big the crawl space is, whether it has vents and what equipment sits down there. We reply within one business day, and then I come out to look at the space and give you a free estimate on site, with no obligation.
Inside city limits, the city Building Department issues permits for alterations, repairs and changes. Its permits page names work like structural changes and electrical, not crawl space insulation, so whether your job needs a permit isn't settled there and the department is the place to ask. Outside West Lafayette and Lafayette, most of the county goes through the Tippecanoe County Building Commission, so your address decides which office you deal with. We check which office covers your address and handle the permit side with that office when your job calls for one. If you'd rather act as your own general contractor on a West Lafayette permit, the city asks you for your subcontractor and bond information.
Around here we see a lot of older houses with vented crawl spaces, fiberglass batts sagging out of the joists, and ductwork or a furnace running under the floor. We do the same work in Lafayette and Crawfordsville, and it starts the same way, with a look at what's down there.
For most houses, sealing and insulating the crawl space walls is the better choice, and building science guidance calls it a best practice in every climate. Some houses still do better with the floor above as the boundary. Which one fits yours is what I look for on site.
No, closing the vents isn't enough to turn a vented crawl space into a sealed one. Closing them by themselves can raise the moisture down there. If a furnace or water heater that draws its air naturally sits in the crawl space, it can create a deadly situation. That's why the vents are one of the last steps, after the moisture plan and the equipment are sorted out.
A sealed crawl space always needs a way to dry out, and one of the most effective is sending a small amount of conditioned air from your heating and cooling system into the space. So the plan for a sealed crawl space can involve your furnace and air conditioner. We work that out before the vents get closed, not after.
Crawl space insulation usually costs about $1 to $6 per square foot across the US. Where your job lands depends on walls or floor, the material, whether old insulation has to come out and how hard the space is to work in. I'll give you the number for your house after I've looked at it.
In a vented crawl space, fiberglass batts come loose over time and soak up moisture, which cuts how well they insulate and can lead to mold and damage to the framing. One cost guide calls them the most common choice down there and the most problematic. When we find wet or sagging batts, they come out before anything new goes in, because fresh insulation over a soaked mess keeps the problem.
Usually, yes. Most codes require a covering of gypsum board, the same stuff as drywall, over foam insulation, because some foams can give off toxic or flammable gases when heated. Some foam products are made and tested to lower that risk, but whether one meets code at your address is the local office's call, so we check before we spray.
