Quick answer
If only the glass has fogged, ask about replacing the sealed unit before buying a whole window. If your main goal is lower heating bills, get the attic and air leaks looked at too. In a home built before 1978, window replacement counts as renovation under lead-paint rules, so hire accordingly.

Bend window companies to compare
These companies sell, install or repair residential windows in the area. They are listed alphabetically. Two appear on Milgard’s dealer locator for Bend, but we couldn’t read a company website for them, so they have fewer details here and it’s especially important to confirm their license and services directly.
Company details were reviewed in October and November 2026. License numbers are shown as the company publishes them or as they appeared in state records at that time. Services, staff and license status change, so confirm what matters directly and in writing.

Repair, new glass or a new window?
- Fogged glass in a sound frame: the seal has failed. A new sealed glass unit may solve it.
- Sticky sash or a window that won’t stay up: ask about balancers and hardware first.
- Drafts around the frame: this may be an air-sealing or trim issue, not the glass.
- Rot, water stains or soft sills: find the water source before ordering anything. Flashing, gutters or roof problems can be the true cause, so talk to a gutter company or roofer if needed.
- Old single-pane or aluminum frames: this is the strongest case for full replacement.
Retrofit versus full-frame installation
A retrofit or insert fits a new unit into the existing frame. It’s less disruptive and usually costs less, but it keeps any hidden problems around the old frame and can reduce the visible glass.
A full-frame install removes the old window down to the rough opening. It lets the installer inspect for damage and redo the flashing, but costs more and may disturb siding and trim. That makes it a better fit for leaks, rot or a planned siding project.
Ask which method each company is quoting. Two bids can look far apart simply because they aren’t the same job.
What to specify for Bend
- U-factor and solar heat gain: compare the ratings on the NFRC label, not brand claims. Bend’s long heating season and strong summer sun mean west-facing rooms may need different thinking than north-facing ones.
- Bedroom egress: a replacement must not leave a bedroom without a compliant exit. Ask before changing styles or sizes.
- Permits: ask the City of Bend Building Safety Division whether your project needs a permit, especially when you’re changing an opening’s size. Don’t rely on a general rule from a national website.
- Wildfire code: Bend’s R327 wildfire code took effect in May 2026 for new homes and new accessory structures, not renovations of existing homes. You may still want to discuss glazing and screens if you’re on a high-risk lot.
- HOA rules: many Bend communities review window colors and grid patterns. Get approval before ordering, because custom units are often non-returnable.
Homes built before 1978
Oregon’s Construction Contractors Board says only contractors with a Lead-Based Paint Renovation license can bid on or perform covered renovation work on homes built before 1978, unless testing shows there’s no lead paint. Window replacement is treated as renovation. Ask for the license, and how the crew will contain dust and clean up.
Energy Trust incentives
Energy Trust of Oregon’s single-family fact sheet effective January 2025 listed up to $1.50 per square foot for qualifying windows, based on the efficiency rating. Check the current amount and rules, and your eligibility by utility, before relying on it. Then compare the payoff against insulation and air sealing, which may do more for your heating bill at a lower cost.
How to get comparable quotes
Ask each company to quote the same set of windows and write down:
- Window count, sizes and locations
- Brand, series, frame material and color
- U-factor and solar heat gain for each type
- Retrofit or full-frame method
- Flashing, trim and siding repair
- Lead-safe practices for older homes
- Permit responsibility
- Disposal of the old windows
- Lead time and install duration
- Product and labor warranties, including transferability
Our contractor bid comparison checklist gives you a simple way to line those details up side by side.
Red flags
- A one-day-only price
- A bid that doesn’t state the install method
- No NFRC ratings on the proposal
- Rot or leak signs waved away
- A dismissive answer to lead questions on a pre-1978 home
- A large deposit with no order or delivery terms
- Energy savings promised without any details about your home
Common questions
Can I replace only fogged glass?
Often, yes. If the frame and sash are sound, a glass shop may be able to replace the sealed unit. Ask for a price on both the glass and a full window so you can compare them, and check any remaining warranty first.
Do I need a permit to replace windows in Bend?
It depends on the work, especially if an opening changes size. Confirm with the City of Bend Building Safety Division, or Deschutes County if you are outside city limits, and state who is responsible in your contract.
Does window replacement in an older home trigger lead rules?
For homes built before 1978, Oregon treats window replacement as renovation, and the contractor needs the appropriate lead-based paint renovation license unless testing shows no lead paint.
Are new windows the best way to lower my heating bill?
Not always. Attic insulation and air sealing often cost less for the savings. New windows are easier to justify when existing ones are failed, leaking, unsafe or uncomfortable.
What is the difference between retrofit and full-frame?
A retrofit fits inside the old frame. A full-frame install removes it, which allows flashing and damage to be addressed but usually costs more and may involve siding and trim work.
