Cold floors, a hot upstairs or a drafty room over the garage? We seal the gaps, then insulate where it actually pays off.
Home insulation in West Lafayette means adding insulation to the attic, floors, crawl space and basement rim joists of your house and sealing the air leaks around them, so you spend less heating and cooling it. At D&T West Lafayette Spray Foam Insulation, we look at the whole house before we recommend where any of it goes.
Most calls start with a cold room, a hot upstairs in summer, a drafty older house or a power bill that doesn't add up. The price moves with how many areas need work, how much is already up there, whether old material has to come out, how many gaps need sealing and whether foam makes sense anywhere. The schedule mostly turns on whether a roof leak or old wiring has to be fixed first and whether your job needs a permit. When I come out for the estimate, I look at your house and give you the figure for it.
I'm the one who comes out to look at your house and give the estimate, and I work alongside our crew when we install. What I found in your attic with a flashlight is what we fix, and you don't have to explain your house twice.
We've been doing this since 2023, and attics and air sealing are what we're known for. It's the unglamorous part, closing the gaps around lights, pipes and the hatch, but it's what makes the insulation you pay for actually count.
We're fully licensed and insured, so the crew working in your attic, under your floors and in your crawl space is covered while we're in your house. It's a fair question to ask any contractor before they climb into your attic, and you should ask it.
If your attic already has plenty and the real trouble is a leak under the house, I'll say so rather than sell you more. Call (765) 250-8264 or use the form on this page, and I'll come out and take a look.
Call (765) 250-8264 or fill out the form with your address, and mention any roof leaks, vermiculite or old wiring you know about. We reply within one business day to set a time, and then I come out, look at the attic, floors and crawl space, and give you a free estimate with no obligation.
Inside West Lafayette city limits, the city's Building Department issues permits for residential projects, and the city says alterations, repairs and changes to existing buildings need one. Its permit list names new construction, structural changes and electrical work and asks anyone who's unsure about a project to contact its office, so whether your insulation job needs a permit is a question for them, not a guess. In the New Chauncey Historical District, plans go first to the Department of Development and the Historic Preservation Committee reviews them before the Building Department issues the permit, which adds a step to the schedule. Outside city limits, the city points you to the City of Lafayette or the Tippecanoe County Building Commission. We check which office covers your address and handle the permit side with that office when your job calls for one.
We're based in West Lafayette and work across the cities around it, including Lafayette, Crawfordsville, Frankfort and Monticello. A lot of what we see here is older houses with a few inches of settled insulation in the attic, open gaps around chimneys and plumbing, and crawl spaces nobody has looked at in years. We also get calls from landlords with drafty rentals and tenants complaining about the cold.
There's no flat price, because the cost comes down to how many parts of the house need work, how much insulation is already there and how many gaps need sealing first. Old material that has to come out, repairs like a roof leak, and foam instead of loose fill all push it up. I'll give you the number for your house once I've looked at it.
Yes. Money spent on insulation can be wasted if the holes and gaps in ceilings, walls and the foundation aren't sealed first, because air moving through them carries heat right past the new material. You get the most from the job when sealing is in the plan and comes first, which is how we lay it out.
Match the type to the space. Blankets, sold as rolls or pre-cut batts, are the most common type in US homes and suit open framing, while loose fill can fill any space. Loose fill also goes in without disturbing the structure or finishes, so it fits finished areas you want left the way they are.
Look for damp insulation under a roof leak, moldy or rotted rafters, and vents blowing moist air into the attic, since those should be fixed before new insulation goes in. Old knob and tube wiring can be a fire hazard when insulation touches it, and lots of unsealed recessed can lights need special care. It's also worth asking how your attic vents today, because little or no ventilation is a problem of its own.
Leave it alone. The EPA advises assuming vermiculite may be contaminated with asbestos and leaving it undisturbed. If you think you have it, tell me before the estimate, and we'll plan the insulation job around leaving it undisturbed.
It can, if a gas furnace, water heater or dryer isn't venting properly, because a tighter house lets carbon monoxide build up. ENERGY STAR advises having a heating and cooling technician check those appliances for proper venting, so plan that in when you plan the sealing.
