Retrofit insulation in Manhattan KS - an older house that stays comfortable
Drafty rooms and a hot upstairs usually mean your older house is short on insulation. We add it where it helps most.

When retrofit insulation makes sensefor older Manhattan homes


Retrofit insulation in Manhattan, KS usually starts with a complaint we hear a lot: a drafty room, a hot upstairs, the room over the garage or a power bill that keeps climbing. In an older house, that usually means the attic floor or the walls are short on insulation, and a retrofit adds to what's already there.
We start by checking the attic insulation you already have and how many inches are up there. Then we look at the walls and tell you where adding more will help most. We'd rather spend that time up front than put material where it won't do much for your house.
Price turns on how much area needs filling, how much is already there and whether old material has to come out first. The schedule turns on what we find, because a roof leak or suspect insulation gets handled before anything goes on the calendar. Your estimate shows the order we'd work in and what it costs.
You'll hear what we found and what we'd do first, so call (785) 236-2032 when you want someone to look up there.
Where retrofit insulation goes in your house
Every older house is short in different places, so we match the method to what we find. For most of them, sealing the gaps and topping up loose fill beats foam.
Attic floor top-up
Most older houses are short up top, so we add blown-in insulation, loose fill blown through a hose, over what's already there once it checks out.
Older walls
Older walls often have little or nothing in the hollow spaces. We check a few cavities before we recommend filling them, so you only pay for walls that need it.
Attics with ductwork
When ductwork runs through the attic, spray foam insulation is usually worth its higher cost, because it seals air and insulates in one pass.

Why homeowners call Sterling in Manhattanfor the corners nobody checks
I started this business in Manhattan in 2023 after learning the trade on a municipal crew, where every job got checked before sign-off, and we run our jobs the same way.
I look at every job myself
I come out to every estimate myself, and I'm on site with our own installers while they work, so the person who planned your job sees it done.
We check under the old layer
Before adding anything, we look at what's already up there, because fresh insulation over a soaked or droppings-filled layer just leaves the problem in place.
Full corners, clear vents
We keep coverage full at the attic edges and the eave vents open, because thin corners and buried vents are where these jobs usually go wrong.
Licensed and insured
We're licensed and insured, and you can ask to see proof at the estimate, the same as you would with anyone working on your house.
Backed by our satisfaction guarantee
We explain what each step costs and why it comes when it does, so you know what you're paying for before any work starts.

Questions about retrofit insulation
What does attic insulation cost in Kansas?
A blown cellulose upgrade for a typical 1,500 sq ft attic in Kansas usually costs about $1,500 to $5,400 per job. That's the usual price across the state, not our quote, and where your house falls comes down to the things covered up top, like how much is already there. Your own figure comes from the estimate after I've looked at your attic.
Should air sealing come before insulation in an older house?
Yes, because money spent on insulation can be wasted if the holes and gaps in ceilings, walls and the foundation aren't sealed first. Air sealing, closing those gaps, keeps outside air from moving straight through the new material, which is why it's the first thing our crew does.
Can walls be insulated without opening them up?
Usually, yes. The dense-pack method fills the hollow spaces inside the wall frame through small holes cut from the outside or inside, and it suits houses that are short on insulation where you want as little tearing up as possible. We'll tell you at the estimate whether your walls are a good fit.
What should I do if my attic has vermiculite insulation?
Get it tested before any insulation work goes on the calendar, because federal building guidance says vermiculite may contain asbestos. It's the pebbly, gray-brown loose fill some older attics have, and we leave it alone and add nothing over it until the test comes back.
How do I choose between blown cellulose and fiberglass for my attic?
If your attic is vented, open to outside air, you can go with either one, since both can be blown across the attic floor to help it hold back heat. I'll look at what's up there now and talk through which fits your house.
How do I check an insulation contractor's license in Manhattan, KS?
Ask which license they hold, because the city accepts Commercial A, Combination B and Residential C licenses. License applicants also have to show liability insurance of at least $500,000 per occurrence, so it's fair to ask for proof of that too.
