Homes and office buildings across Greenwood Village
Greenwood Village is mostly quiet residential streets with roomy lots, plus a business side of office buildings along the main roads. We're an insulation contractor based in Castle Rock, and we come up here for homeowners and property managers alike, doing the same work we do next door in Centennial and down in Meridian.
The houses run from older ranches that have been added onto over the years to big newer homes with vaulted ceilings and more than one furnace. That spread is why no two attics here get the same plan from me.
Our services in Greenwood Village, CO
- Attic insulation
A lot of the older ranches here still have thin, settled insulation from when they were built, and that's usually what's behind the cold rooms and the high power bill. We measure how many inches are up there and top it up with blown-in, which is loose fill blown through a hose, until the whole attic sits at one even depth.
- Attic air sealing
Can lights, plumbing pipes and the attic hatch in older houses leave gaps that let house air slip into the attic, so new insulation ends up fighting a draft. We do the air sealing first, closing those gaps with foam and caulk, before anything goes on top.
- Closed-cell foam insulation
On the larger homes here, the furnace and ductwork often sit in the attic, and that's when I'd choose foam over loose fill even though it costs more. We spray closed-cell foam insulation, a dense foam that blocks air and moisture, under the roof deck so the ducts end up inside the insulated part of the house.
- Insulation removal
When old insulation has been soaked by a past roof leak or filled with droppings, laying more over it just keeps the problem. We bag it out, clean the attic floor and find what caused it before anything new goes in.
- Retrofit insulation
The room over the garage is a common complaint in the bigger homes here, because its floor and the short walls under the roof slope usually got the least insulation when the house went up. We fill those spaces and seal the edges so that room stays closer to the temperature of the rest of the house.
- Commercial insulation
Greenwood Village has plenty of office buildings, and property managers call us when one needs insulation done to commercial standards. I spent my first years with a big commercial insulation company working on offices and metal buildings, so we plan the work around tenants and the building's schedule.
What Greenwood Village houses ask of the attic
In the older houses here, the attic usually holds whatever went in when the house was built plus a layer someone added later, and it's often deep in the middle and thin at the edges, which is backward because the edges sit right over your outside walls. Just as often the eave vents are buried under loose fill, so the attic can't breathe and moisture starts showing in the framing. We work in order, sealing the gaps, setting baffles, short chutes that hold insulation back from the vents, and then bringing the depth up evenly from edge to edge.
The bigger homes bring different questions, like ducts running through the attic or vaulted ceilings with little room above them. Price mostly turns on attic size and access, whether old material has to come out, how much sealing there is and whether foam makes sense, and the schedule turns on removal and on whether your job needs a permit and inspections. I'll walk you through all of it in the attic and put it in the estimate I write.

Insulation work up close
Greenwood Village insulation questions answered
What is the best way to find out if my insulation job needs a permit in Greenwood Village?
Ask the city's Community Development department before work starts, because its staff decide whether a permit is needed. The city generally requires permits for alterations and repairs but not for finish work like painting, and insulation isn't on its list of examples either way, though a basement finish is. We check this for your address before we start, and when a permit is needed we apply for it and set up the inspections.
How do I know if my Englewood address is actually in Greenwood Village?
An Englewood mailing address doesn't settle it, because many homes inside Greenwood Village use Englewood on their mail. That matters for insulation work, since the city your house actually sits in is the one whose permit and contractor rules apply. We look up which city or county office covers your address before we start, so you don't have to sort it out.
Do insulation subcontractors need their own Greenwood Village contractor license?
No, not when they work under a licensed contractor's supervision, but the contractor running the job needs a city license before work starts. The city ties that license to the contractor's insurance, including $2 million in general aggregate coverage, and suspends it the moment coverage drops or is cancelled. On our jobs it's our own installers in your attic, not a string of subs.
What hours can an insulation crew work in Greenwood Village?
The city allows construction from 7 a.m. to 7 p.m. Monday through Friday, 8 a.m. to 7 p.m. on Saturday, and 10 a.m. to 7 p.m. on Sundays and observed holidays. We schedule inside those hours, which matters most on foam jobs, since you'll be out of the house for the re-entry time, the wait the foam maker sets before people and pets go back in.
Who needs to be home for an insulation inspection in Greenwood Village?
An adult, 18 or older, has to be there for any interior inspection. The city also wants the permit card posted, ideally where it can be seen from the street, and a hard copy of the approved drawings on hand for the inspector. When your job has a permit, we set up the inspections and give you the time ahead so someone can be home.
How much does insulation cost in Greenwood Village?
Insulation cost here comes down to the size and access of your attic or walls, what's already up there and whether foam or loose fill is the right call, so I give you the number after I've looked. Wet or dirty old material that has to come out adds to the job, and so does a lot of sealing around lights and pipes. If topping up is the better spend than foam for your house, I'll tell you plainly.
