Gresham’s Trusted Window Replacement Contractor — Licensed, Owner-Supervised & Installed to Code
Drafty Gresham windows are rarely a window problem — they're an installation problem. Missing head flashing lets water run into your wall every time it rains.
No sill pan means water pools in the rough opening for years before you see the interior staining. Inadequate air sealing makes the gap between the frame and framing a direct cold-air channel. VResh installs every window with all three — and as a Milgard Warranty Service Provider, we perform warranty repairs that most Gresham contractors cannot. EPA Lead-Safe Certified. Licensed OR #241979 | WA #VRESHCL776ND. Free written estimates. (503) 272–6436.

Why Gresham Windows Are Failing Now
Gresham's housing stock is dominated by homes built between the 1960s and 1980s — and the windows installed in that era were built to standards far below today's energy and moisture performance expectations. Many are now reaching the end of their service life, with failure patterns that are consistent across the region.
Original Aluminum Windows — The Hidden Moisture Problem
Aluminum single-track sliders were standard in many Gresham homes built in the 1960s and 1970s. These windows have no thermal break, meaning they transfer cold directly into the interior. During Gresham’s damp winters, condensation forms on the frame and drains downward into the sill.
Over decades, this repeated moisture exposure saturates the rough sill plate and surrounding framing. On removal, VResh frequently finds structural rot below aluminum window units — even when the interior shows no visible damage.
Failed Seals — Foggy Glass Means Lost Performance
Condensation or haze between glass panes indicates a failed seal in double-pane windows. This is common in windows installed 15–25 years ago — placing many Gresham homes directly in the failure window today.
Once the seal fails, the insulating gas is gone and replaced by moisture. The window loses thermal performance, and interior comfort drops. VResh evaluates whether glass replacement or full window replacement is the correct solution.
Poor "Pocket" Replacements — Problems Hidden Behind New Windows
Pocket replacements install a new window into an existing frame without full removal. When done incorrectly, they leave old flashing failures, missing sill pans, and hidden rot inside the wall.
VResh performs full rough opening inspection on every window project. If previous installations left unresolved moisture issues, we identify and correct them before installing the new unit — preventing repeat failure.
What VResh Actually Does on a Gresham Window Project
Window installation technique determines whether the project performs for 30 years or starts leaking within the first few. Here is exactly what happens on every VResh window installation in Gresham.
Full Removal and Rough Opening Inspection
Full removal of the existing window unit, interior stops, exterior trim, and all casing to expose the complete rough opening. No pocket replacements — full removal is required to install a proper drainage plane and inspect the structural condition of the opening.
What VResh Finds in Gresham Window Rough Openings
- Sill plate rot — caused by decades of condensation from aluminum frames with no thermal break.
- No sill pan — water has been pooling in the rough opening instead of draining outward.
- Missing head flashing — no protection directing water away from the window opening.
- Degraded or absent WRB — original building paper often no longer provides moisture protection.
Rough Opening Repair
If structural damage is found, all compromised material is removed and replaced before installation. This includes sill plate repair, jack stud replacement, and integration with the surrounding wall system. A new window installed into damaged framing will fail — this step ensures long-term performance.
Flashing System Installation
The flashing system is what prevents water intrusion and future rot. VResh installs a complete drainage system integrated into the wall assembly.
The Three Steps Most Window Installers Skip
- Sill pan flashing — directs any water at the base of the opening outward instead of into framing.
- Head flashing — prevents water from entering above the window opening.
- Jamb flashing tape — applied in correct sequence to ensure proper drainage path.
Installation, Air Sealing, and Trim
The window is installed level, plumb, and square, then fastened per manufacturer specifications. Low-expansion foam is used to air seal the perimeter, improving energy efficiency and eliminating drafts.
- Exterior casing installed and sealed
- Interior trim fully completed (no unfinished work)
- Hardware installed and tested
- Final inspection and walkthrough
Window Brands VResh Installs in Gresham
VResh is not a single-brand window dealer. We help Gresham homeowners select the right product for their specific situation and budget. Here are the brands we install most frequently and why.
Milgard — Most-Installed Brand, and VResh Is a Milgard Warranty Service Provider
Milgard is the most-installed window brand in the Pacific Northwest. Their vinyl and fiberglass lines carry a Full Lifetime Warranty for the original purchaser. As a Milgard Warranty Service Provider, VResh can perform warranty-covered repairs on Milgard windows — a designation most Gresham contractors do not hold. If your Milgard windows were improperly installed by an unauthorized contractor, only a Warranty Service Provider can perform the covered repair.
Marvin — For Gresham's Craftsman and Historic Homes
Marvin's Ultimate and Elevate lines offer real wood interiors with fiberglass exteriors — the performance and character of wood windows without the maintenance burden. For older Gresham homes near the historic downtown core where wood window character is important, Marvin is the right recommendation. Marvin carries a 20-year limited warranty on most products.
Jeld-Wen and Others
Jeld-Wen offers solid mid-range vinyl and wood options at competitive pricing — a good choice for Gresham rental properties and larger projects where budget is a constraint without sacrificing correct installation. VResh also installs Pella and Simonton.
Andersen — Wide Selection, Strong Brand Recognition
Andersen's 200 Series (Fibrex composite) and 400 Series (wood interior / Fibrex exterior) cover a wide price range. The 400 Series is particularly popular for Gresham's older bungalows where wood interior character is desired without full custom costs.
Window Replacement Requirements for Gresham Homes
Lead Paint — What Gresham Homeowners Need to Know
With a median construction year of 1981, approximately 43% of Gresham's housing stock was built before 1978 — the federal threshold for lead-based paint regulation. Federal law — the EPA's Lead Renovation, Repair, and Painting (RRP) Rule — requires contractors who disturb painted surfaces on pre-1978 homes to hold EPA Lead-Safe Certification, follow specific containment and work practice protocols, and provide written documentation. Violations reach $37,500 per day per violation.
⚠️ Before Hiring Any Window Replacement Contractor in Gresham for a Pre-1978 Home
Ask directly: "Are you currently EPA Lead-Safe Certified under the RRP Rule?" Then ask to see the certificate.
A contractor without current certification cannot legally disturb painted surfaces on a pre-1978 home, cannot provide required compliance documentation, and exposes your family to lead dust contamination.
VResh Construction holds current EPA Lead-Safe Certification and provides written documentation at project completion.
