These two answer the questions most people arrive with. The topic guides below go deeper on specific symptoms and on how this climate actually behaves. Nothing is listed here before it exists.

What should I diagnose before scoping a project?
Symptoms have causes. Before paying for a quote, learn what ice dams, pebbly attic fill, and condensation patterns are actually telling you about the house.
Ice Dams on Greeley Roofs: What They Actually Tell You
A ridge of ice at the eaves is a heat-loss symptom, not a weather event. What causes it here and what actually fixes it.
Is Your Greeley Attic Insulation Failing?
Six symptoms worth acting on, three that mean nothing, and the one measurement that settles it.
Upstairs Hot in Summer, Cold in Winter — Why?
The most common comfort complaint in Greeley homes, and why it usually is not a thermostat problem.
Vermiculite Insulation in Greeley Attics
Pebbly gray-brown flakes in an older attic. How to identify it, and why the right first move is to stop.
Rodent-Contaminated Attic Insulation and Hantavirus Risk in Greeley
Droppings or nesting material in the attic insulation? What the CDC says about hantavirus risk, safe cleanup, and why this is a removal case.
Can I Insulate Over Knob-and-Tube Wiring in My Greeley Home?
Pre-1940 homes across Weld County commonly carry knob-and-tube wiring — and code prohibits insulating over it. What it looks like and the right sequence to handle it.
Why Do Pipes Freeze in Greeley Homes — and What Actually Fixes It?
A frozen pipe usually means the space around it — not the pipe — is losing heat to the outside. What actually stops it, and when to call a plumber instead.
Attic Mold in Greeley: What's Actually Causing It, and What Cleanup Alone Won't Fix
Dark staining on the sheathing, an inspector's flag, or a remediation quote you want a second opinion on — what actually causes attic mold here, and why cleanup alone often doesn't hold.
How does the high-plains climate change the math?
Greeley sits on open plains east of the foothills, at roughly 4,675 feet. The wind, the swing between day and night, and the city's own published design criteria all change what an envelope has to do here.
Does Altitude Change R-Value in Greeley?
Greeley sits around 4,675 feet. The honest answer about what that does to insulation is: less than you have been told.
Freeze-Thaw Cycles and the Greeley Building Envelope
A wide daily temperature swing works the envelope harder than a cold climate does. What that means for sealing and materials.
How should I use these guides?
Start with whichever question is actually blocking you. If you do not know whether your house needs work, go to your town's page — the housing profile there usually settles it faster than a general article would. If you know you want the work and are trying to figure out what it will cost, start with the rebate breakdown, because in this market the rebate is a large enough share of the total to change the decision.
One thing worth reading even if you think you know it: the rebate page explains which utility pays here. It is the single most commonly wrong assumption about this market, and getting it wrong costs real money.

What the data says
According to Atmos Energy, Atmos Energy rebates residential attic insulation at 75% of total cost where the starting R-value is less than R-20, and publishes the amount that rebate currently pays on its own rebate page.
According to the International Energy Conservation Code, the 2021 IECC sets a minimum ceiling insulation R-value of R-60 in Climate Zone 5 under Table R402.1.3, and Section R402.2.1 allows R-49 to satisfy that requirement only where the full height of uncompressed R-49 insulation extends over the wall top plate at the eaves.
According to the Colorado Energy Office's Weatherization Assistance Program, the Weatherization Assistance Program provides no-cost weatherization services for qualified residents and homes, and lists insulation in attic, floors, and walls among the services a household may receive based on the results of its required free home energy audit.
Take the next step
Want this applied to your actual house?
The free in-home assessment does what no guide can: measures what is in your attic, finds where the envelope leaks, and prices the work with the rebate applied. If the answer is that you do not need anything yet, that is what you will be told.

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 — Greeley builds to the 2021 IECC, which puts attics at R-60, and accepts R-49 only where the insulation carries its full uncompressed depth over the wall top plate at the eaves; anything less is under-spec. (2) Air sealing scope — insulation alone does nothing if air leaks aren't sealed first, so it belongs on the quote as its own line with its own scope, and a blower door test is what documents the before-and-after. (3) Rebate handling — ask who files the rebate paperwork with your gas utility, and confirm what that utility's filing deadline is and that the application will go in inside it. (The federal IRA Section 25C tax credit ended December 31, 2025, and Colorado's HEAR program is closed. Which utility to ask about an insulation rebate depends on your town: Atmos Energy's residential rebates are the primary insulation rebate programs in Greeley, Evans and Eaton, while the natural gas utility is Xcel Energy in Johnstown, for most of Milliken, and for most locations in Severance — Xcel sets out its own insulation and air sealing rebate terms on its rebate page. Income-qualified households can get insulation work done at no cost through the state Weatherization Assistance Program.) (4) Removal scope — older homes often need old insulation removed before new install. If a quote skips all four, get another quote.
Frequently asked
Questions about these guides
Why is the guide list not longer?
Because these are written rather than generated. Each one re-derives its facts for this market — the rebate that actually applies, the code edition the city actually adopted, the housing profile of the specific town — and that takes longer than reskinning a generic article. More follow. Listing unwritten pages as 'coming soon' would pad the site without helping anyone, so nothing appears here until it exists.
Are these guides written for Greeley specifically?
Yes, and that is the point of them. Rebate figures come from the utility that actually serves this area, code references come from the ordinance Greeley itself adopted, housing figures come from Census data for each individual town, and the climate framing is derived for this elevation and this distance from the foothills rather than borrowed from a higher-altitude market.
How current is the rebate information?
Verified August 5, 2026 against primary sources, with a scheduled re-verification in September 2026 and quarterly thereafter. The rebate page carries its verification date visibly, along with the utility's own statements that amounts are subject to change and available only while funding lasts. Where something could not be verified, the page says so instead of guessing.
Do you cover new construction?
No, and the rebate program does not either — Atmos explicitly excludes residential new construction from its rebates. This site is about retrofit work on existing homes. New construction is a different process, usually handled through the builder and their subcontractors.
My home is nearly new — is there anything here for me?
Possibly less than you would hope, and the town pages say so plainly where the data supports it. Several towns here are overwhelmingly recent construction, and for those homes the honest answer is usually that no insulation work is warranted yet. The useful reading for you is the air sealing guide above, since that is the one measure that often helps on newer housing — and it carries a rebate with no starting-R-value threshold.
Can I get help paying for this work?
If your household is income-qualified, the state weatherization program does the work at no cost, and the income limits are higher than most people assume. The rebate guide covers who administers it locally and what the thresholds are in this county. It is worth checking before you scope a paid project.
