Condensation between the panes, an aluminum frame that sweats every January morning, a slider that takes two hands — those are the everyday complaints in Gresham's older housing. New units fix the drafts and the noise. Tell us how many openings and what you have now, and local installers will quote it.
Require opening measurements, frame and water-damage findings, installation method, flashing and air-sealing details, product performance, interior and exterior finish scope, permits when applicable, cleanup and warranty responsibility. Compare bids using the same openings and installation assumptions.
Inserts fit inside the existing frame: faster, cheaper, no exterior trim disturbed, but you lose a bit of glass area and you keep whatever is behind that frame. Full-frame removal takes it back to the rough opening, which lets the installer inspect for rot and flash the opening properly. If there is any moisture history around a window, full-frame is the right choice.
U-factor measures heat loss and lower is better; for our mixed heating climate look for a low U-factor first. Solar heat gain coefficient matters more on west and south glass, where summer heat is now a real consideration. Argon fill and a low-e coating are standard on decent units. Do not pay a premium for triple glazing without a clear reason.
Homes near Powell, Division, Burnside, and the MAX line hear more traffic than the rest of Gresham. Laminated glass or differing pane thicknesses cut sound noticeably better than simply going to triple pane. If quiet is the actual goal rather than energy savings, say so up front, because it changes which product a bidder should specify.
Original sliders and steel entry doors from the 70s and 80s leak air around worn weatherstripping and warped thresholds. Replacing them alongside windows shares the crew's mobilization and often the same flashing details. An insulated fiberglass entry door with a good sweep is a small project with an outsized comfort payoff.
Window performance depends on how the unit connects to the wall, not only the glass label. Ask the installer to describe removal, sill and framing inspection, flashing integration, drainage path, perimeter air seal and exterior sealant. If siding or trim limits access, identify what will be removed and restored. Photograph concealed damage and flashing before finishes cover it. This creates a record of the assembly and prevents an insert-window price from being compared as if it included full-frame water-management work.
Test every sash, lock, screen and egress opening after installation. Confirm the unit is square, operates without binding and has the specified safety glazing where required. Review interior casing, stool, drywall and paint as well as exterior trim, sealant and siding transitions. Ask how labels needed for warranty or inspection will be preserved. Clean tracks and glass, remove protective film on schedule and record product identifiers. If an opening was altered, keep approved plans and final inspection evidence with the window warranty and installation photographs.

Homes built here through the late 70s often have single-pane aluminum sliders that conduct cold straight through the frame and puddle water on the sill every winter morning. Early 80s and 90s double-pane units are now failing at the seals, which is what causes that permanent haze between panes. Both are prime replacement candidates.
Window replacement generally requires a permit through City of Gresham Development Services, or Multnomah County outside the city, and bedroom windows must meet egress size requirements. If you are enlarging an opening or finishing a basement bedroom, egress becomes the governing detail. A licensed installer handles the permit and the sizing.
East wind events push rain against Gresham windows at pressures that reveal any weakness in installation. Proper sill pan flashing, a sloped sill, and sealed head flashing are what keep water out of the wall. Ask installers how they flash the sill — the answer separates careful crews from fast ones.
| Scope | Works when | Confirm in writing |
|---|---|---|
| Insert replacement | Existing frame is sound, square and dry | Remaining glass area and frame preparation |
| Full-frame replacement | Frame, flashing or water control needs renewal | Exterior opening and interior finish restoration |
| Opening alteration | Size or location changes | Structure, permit and exterior-cladding details |
| Targeted repair | Hardware or one bounded component failed | Part compatibility and weather seal |
Installed vinyl replacement windows commonly run $650 to $1,200 per standard opening, with fiberglass and clad-wood units often $1,200 to $2,200 each. A whole-house project of 12 to 16 windows frequently lands between $10,000 and $25,000 depending on material and whether you go insert or full-frame. Large picture units, bays, and enlarged egress openings cost considerably more. Be cautious with high-pressure same-day discounts, and get at least two bids specifying the same product line.
Eleven windows in three days, every opening closed up the same day it opened. The morning condensation on the sills is completely gone.
We live near a busy street and asked for sound over savings. He specified laminated glass on the front rooms and the difference is dramatic.
Two bedroom windows had rot in the frames, so he recommended full-frame instead of inserts and re-flashed both openings. He also checked the sizes against egress before anything was ordered.
The seal has failed, and while some companies offer defogging services, results vary and the insulating gas is gone regardless. In most cases replacing the sash or the whole unit is the durable fix. If several windows in the house are the same age, expect the rest to follow.
They help, but rarely dramatically. Attic insulation and air sealing usually deliver more per dollar. Where windows win is comfort — no cold draft along the sofa, no condensation on the sill, and noticeably less street noise. Buy them for that and treat savings as a bonus.
A typical Gresham home is often two to four days for inserts and longer for full-frame work with exterior trim. Installers usually complete each opening the same day it is removed, so you are not left with a hole overnight. Confirm that in the contract.
No. Many homeowners start with the worst elevation or the rooms they use most and phase the rest. You lose a little volume pricing that way but it spreads the cost. Ask whether the installer will hold pricing on a second phase.
Some older Gresham-area farmhouses have solid old-growth wood sash that outlasts modern replacements. Restoration plus good storm windows can perform close to a new unit while keeping the character. It is craft work, so ask specifically for someone who does it.
An insert generally retains a serviceable existing frame; full-frame work removes more of the opening so frame, flashing and water-control conditions can be corrected. Ask which components remain.
Known damage should be scoped, while concealed work needs a documented allowance, unit price or written change process. Require photographs before additional removal is authorized.
Keep product labels, approved permit records when applicable, installation and flashing photographs, care instructions, warranty contacts and the final paid contract.
