Insulation work in Junction Citydone by our Manhattan crew
We're based in Manhattan and come over to Junction City for hot upstairs rooms, cold floors over crawl spaces and the room over the garage. We do the same work in Fort Riley and Abilene.
What you pay depends on what's already up there, whether old insulation has to come out first, how many gaps need sealing, and foam versus loose fill blown through a hose. Those same things set the schedule, and your estimate gives you the numbers.
Call (785) 236-2032 or send us a message, and I'll come out to look at your attic myself.
What we do in Junction Cityfrom attic to crawl space
Here's every service we bring to Junction City homes, rentals and businesses, from sealing the attic floor to clearing out old insulation.
- Spray foam insulation Spray foam insulation fills odd framing and tight spots in one pass, sealing air as it insulates, which is why it costs more.
- Attic insulation Most hot upstairs rooms start overhead, so our attic insulation work begins by measuring the inches already up there.
- Blown-in insulation Blown-in insulation tops up an open attic floor without disturbing what's sound underneath, once the gaps below it are sealed.
- Home insulation When a whole house feels drafty room to room, home insulation starts with working out the order, sealing first and insulating second.
- Insulation removal Old insulation soaked by a roof leak or full of droppings needs insulation removal before anything new is worth adding.
- Crawl space insulation Cold floors usually point down, and crawl space insulation covers the underside and closes the gaps around pipes.
- Wall insulation Older walls that feel cold to the touch can take wall insulation, usually through small holes rather than opening the whole wall.
- Air sealing services Air sealing, closing gaps before insulating, is often what fixes a drafty room that more insulation alone never did.
- Basement insulation A basement loses heat through its walls, and basement insulation helps the floor above it stay warmer.
- Closed-cell foam insulation Closed-cell foam is dense foam that blocks moisture, a good fit for rim joists and damp crawl space walls.
- Open-cell foam insulation Lighter and softer, open-cell foam goes under roof decks and into walls where moisture isn't the worry.
- Commercial insulation Offices, shops and rental buildings get the same look under the old material with our commercial insulation work.
- Crawl space vapor barrier A crawl space vapor barrier covers the dirt so ground moisture doesn't soak the insulation and framing above it.
- Vapor barrier installation In basements and walls, vapor barrier installation puts the barrier on the right side so moisture doesn't collect inside.
- Attic air sealing With attic air sealing, warm air from the rooms below stays out of the insulation, so it does its job.
- Retrofit insulation For older houses, retrofit insulation adds to what's there instead of starting over when the old material is still sound.
Why Junction City calls usfor the parts nobody sees
We're a small Manhattan crew that's been insulating homes since 2023, and we work slowly enough to show you what we found and why each step comes when it does.
I look at every job myself
The person who climbs into your attic for the estimate is me, and I'm back on site with our own installers when the work happens.
We check under the old insulation
Before adding anything, we pull back the old material to look for leaks, droppings and buried vents, because new insulation over a problem just hides it.
Crawl spaces and corners count
I care most about the places nobody looks, so crawl spaces, attic corners and the hatch get the same care as the open attic floor.
Trained where work got inspected
I learned this trade on a municipal crew in public buildings, where every job was checked before sign-off, and we still work to that standard.
Licensed and insured, with our guarantee
We're licensed and insured for the work we do in Junction City homes and buildings, and our work is backed by our satisfaction guarantee.
From first call to walkthroughwith me there start to finish
You deal with me from the first visit to the last walkthrough, so you're never explaining your house twice, and you know the order of the work before anything starts.
You call or send a message
Call (785) 236-2032 or use the form and tell us what you're noticing, a hot room or cold floors, and we'll set up a visit.
I come out and look
I go through the attic, walls, crawl space or basement myself, then walk you through what I found and the order I'd do it in, with your estimate.
Permits, then the work
We handle any permit the job needs with the city, then our installers and I do the work. With foam, I'll tell you the re-entry time, when the kids and pets can come back in.
We walk through it together
When we're done, I walk through the finished job with you, corners and edges included, so you see the sealed gaps and not just the top layer.
What Junction City attics needbefore new insulation goes in
These are the things we find most often when we open up attics and crawl spaces around Junction City.
Thin, settled insulation
Older attics have often settled to a few inches, thinnest at the eaves, so we measure first and build the edges up.
Gaps nobody sealed
Can lights, plumbing pipes and the attic hatch leak warm air, so we seal them before any insulation goes over the top.
Buried eave vents
Insulation pushed into the eaves stops the attic from breathing, so we hold it back and keep air moving to protect the framing.
Ductwork up in the attic
Most attics do fine with sealed gaps and topped-up loose fill, but when ducts run up there, foam usually earns its higher cost.

Our work in Junction Citystarts with the city's rules
Junction City's Building and Code Enforcement Division issues permits for work like roofs, siding, additions and basement remodels, and the city says that's only a few of them. Insulation isn't on that list, so whether your job needs one is a question for the division, and we ask it before we start.
The city charges a penalty when a permit is taken out after work starts, double the permit fee up to $500, which is why we don't wait to ask. It also requires anyone doing contracting work in Junction City or Geary County to hold a city license, which is worth asking any contractor about.
