We've Got It. Here's What Happens Next.
We've got your info and are routing it to a local pro. When they call, here's what to look for in the quote you receive: (1) R-value target — the Colorado Low Energy and Carbon Code sets a ceiling minimum of R-49 in Climate Zone 5 (Table R402.1.3); R-38 qualifies only where uncompressed insulation extends full-height over the top plate at the eaves. (2) Air sealing scope — insulation and air sealing work together; sealing the leaks first is what lets the insulation do its job. If a quote skips both, get another quote. The federal IRA Section 25C tax credit ended December 31, 2025, and Colorado's HEAR single-family program is now closed for both Region 1 (the Front Range) and Region 2. Xcel Energy programs are the ones still paying on Denver-area insulation projects in 2026.
Quick reality check: If your home was built before 1990 and your bills keep climbing, you probably need this. If it was built after 2010 and your bills are normal, there is usually still a gap, but the payback is slow enough that it can wait. Either way, we'll tell you straight.

Why insulate
Why do Broomfield homes need insulation attention?
Broomfield is one of the metro's newest suburbs — most homes were built between 1995 and 2015, under codes that asked for less ceiling insulation than the R-49 minimum in force today. So the angle here runs two ways: closing that gap, and extracting comfort and efficiency gains from homes that look fine on paper but underperform in practice.
Broomfield's utility picture is the unusual element among Denver-metro suburbs. Most of the city is served by Xcel Energy, but parts of northern Broomfield (including some of Anthem and adjacent neighborhoods) are in United Power's service territory. The rebate programs differ — Xcel's 2026 Insulation and Air Sealing Rebate plus Whole Home Efficiency Bonus applies in Xcel territory; United Power offers its own Member Energy Efficiency rebate program. Knowing which utility serves your address is the first step in maximizing rebates.
Builder-grade fiberglass batts settle, sag, and gap within ten to fifteen years. A 2008 Broomfield home that started at R-38 in the attic is commonly sitting at an effective R-25 to R-32 today. Topping up with blown-in cellulose plus targeted air sealing typically delivers a noticeable comfort improvement and meaningful HVAC runtime reduction. The 2026 Xcel Whole Home Efficiency Bonus adds a bonus rebate of 25% of the standard rebates you received for each measure when three or more measures are completed within two years of enrolling — insulation and air sealing together are two of the three; a third measure within that window completes it. Xcel requires you to enter the program first, through a Home Energy Squad Plus visit or a Blower Door or Infrared Home Energy Audit by a qualified participating contractor.
According to Xcel Energy, to receive a rebate, all insulation and air sealing upgrades must be completed by a participating contractor.

Common projects
What insulation projects are most common in Broomfield?
The right material and scope depends on your home's age, current insulation, and where comfort or efficiency is falling short.
Attic Insulation
Broomfield homes typically need 6-10 inch top-ups over settled batts — how far that closes the gap to R-49 depends on what is actually up there now.
Wall Insulation
Walls in Broomfield homes are generally insulated to code; dense-pack retrofits are usually needed only in specific cold-spot areas.
Crawl Space
Most Broomfield homes are slab-on-grade or full-conditioned-basement; crawl space work is rare here.
Blown-In Insulation
Blown-in cellulose top-ups are the standard Broomfield retrofit — fast, clean, and rebate-eligible at recommended depth.
Spray Foam
Closed-cell spray foam at the rim joist of a finished basement seals a full-perimeter seam in most Broomfield homes.
Energy Audit
Worth it on any Broomfield home over ten years old — finds settled batts and air-leak penetrations before scoping rebate-eligible work.
Cost & the cost of waiting
How much does insulation cost for Broomfield homes — and what does waiting cost?
Broomfield homes average around 2,400 square feet, and no primary source publishes a Denver-specific installed cost, so this page doesn't print a figure. Larger Anthem and Wildgrass custom homes (3,000+ sq ft) need proportionally more material. The free in-home estimate prices your specific home. Cost drivers specific to Broomfield are simpler than older suburbs: clean attic access, no asbestos concerns, no knob-and-tube workarounds. Where Broomfield costs can rise: vaulted ceilings with limited attic space, knee-wall sealing in 1.5-story bonus rooms, and tray ceilings requiring different approaches than flat attics.
Every winter you don't upgrade a pre-1990 attic, you're heating the attic through the ceiling.
According to ENERGY STAR, recommended insulation levels for retrofitting existing wood-framed buildings in Zones 6, 5, and 4C are R-60 added to the attic if your attic is uninsulated, or R-49 if you already have 3-4 inches of insulation.
According to Xcel Energy's Whole Home Efficiency program page, customers who install three qualifying measures within two years of enrolling receive an additional bonus rebate of 25% of the standard rebates they received for each measure, and to be eligible for the program a customer must schedule a Home Energy Squad Plus visit, or have a qualified, participating contractor complete a Blower Door or Infrared Home Energy Audit.
According to Xcel Energy's Colorado demand-side management filing for insulation and air sealing, filed January 2020, pre- and post-improvement blower door results in CFM 50 are required for these projects, and where air sealing is required a minimum 20% reduction in air leakage must be achieved to qualify.

Frequently asked
What do Broomfield homeowners ask most about insulation?
Should I do this if my Broomfield home was built after 2010?
Not urgently — but 'built after 2010' is not the same as 'done.' Post-2010 Broomfield homes typically went up with R-30 to R-38 in the attic, under the R-49 ceiling minimum the Colorado Low Energy and Carbon Code sets for Climate Zone 5B. If your bills are normal and your comfort is fine, the return is slower than on a pre-1990 attic. Where these homes pay back: settled batts and unsealed attic-plane penetrations show up in the 10-15 year window. We'll tell you straight when we look at it.
Does my Broomfield home qualify for Xcel rebates?
Most Broomfield addresses are in Xcel Energy service territory and qualify for the 2026 Xcel Energy Insulation and Air Sealing Rebate, plus the Whole Home Efficiency Bonus when three or more efficiency measures are completed within two years of enrolling. Most of Broomfield is in Xcel Energy service territory; some northern Broomfield neighborhoods are in United Power service territory and qualify for that utility's separate Member Energy Efficiency rebate program. The pro on your job confirms eligibility against your specific address before scoping work.
How much does attic insulation typically cost for a Broomfield home?
Broomfield homes average around 2,400 square feet, and no primary source publishes a Denver-specific installed cost, so this page doesn't print a figure. The full quote depends on home size, current insulation level, and required pre-work — the free in-home estimate gives exact numbers, not a range.
Do you serve all of Broomfield?
Yes — every Broomfield ZIP and neighborhood, plus the surrounding Denver metro. Service areas listed at the bottom of this page show the neighborhoods the contractor works in regularly.
What R-value should I aim for at Denver's altitude?
Denver sits in IECC Climate Zone 5B. Table R402.1.3 of Denver's energy code (the 2021 IECC as amended) sets the ceiling insulation minimum at R-60; R-49 satisfies that requirement only under Section R402.2.1, where the full height of uncompressed R-49 insulation extends over the wall top plate at the eaves. Walls are R-30 cavity, R-20 cavity plus R-5 continuous, R-13 cavity plus R-10 continuous, or R-20 continuous. ENERGY STAR separately recommends adding R-60 if your attic is uninsulated, or R-49 if you already have three to four inches.
Is my Broomfield home in Xcel or United Power territory?
Most of Broomfield is served by Xcel Energy and qualifies for the standard 2026 Xcel rebate programs. Parts of northern Broomfield (sections of Anthem and adjacent neighborhoods) are in United Power territory, which has its own Member Energy Efficiency rebate program. Your most recent electric bill names the utility. We confirm rebate eligibility against your specific address before scoping work.
