Gresham’s Go-To Dry Rot Repair Contractor — Source Fixed First, Surface Fixed Second
Every Gresham contractor who patches dry rot with Bondo or epoxy filler creates a delay, not a repair. The rot continues behind the patch.
The moisture source that created it is still there. VResh identifies the moisture pathway first — missing head flashing, absent kickout, failed deck ledger flashing, grade clearance violation — removes all compromised material back to sound wood, corrects the moisture entry point, and reinstalls with the technique that prevents recurrence. EPA Lead-Safe Certified. Licensed OR #241979. Free written estimates. (503) 272–6436.
VResh is owner-operated. Vlad personally oversees every dry rot assessment and repair in Gresham — you get one accountable person from inspection through reinstallation.
Why Gresham Entry Doors Are Being Replaced Now
Gresham's west and southwest-facing entries face the prevailing Pacific storm track — a direct rain exposure path that is compounded by Johnson Creek Valley humidity during Gresham's long wet season. Most of Gresham's original entry doors from the 1960s–1980s are now 40–60 years old. They were designed to a different building code standard, offer minimal energy performance by current measures, and many are showing structural failure at the threshold and frame. Three problems bring Gresham homeowners to VResh for door replacement.
Threshold Rot — What Happens Without a Sill Pan Over 40 Years
A sill pan is a formed tray at the bottom of the door rough opening that captures any water that gets past the threshold and directs it to the exterior. Most original entry door installations from the 1960s–80s did not include a sill pan. Over 40 years in Gresham's wet climate, water that worked past the threshold saturated the rough sill plate, rotted the framing below the door, and in many cases softened the subfloor at the entry. VResh finds compromised sill framing at the entry on the majority of original-door removal projects on Gresham's older homes.
Settling and Drafts — When the Door No Longer Seals
Entry doors in Gresham's older homes have often settled slightly as the house has moved over decades. A door that no longer closes squarely against its weatherstripping creates persistent drafts and energy loss. In many cases, the weatherstripping itself has long since failed — original foam or brush weatherstripping from the 1970s has no remaining seal. VResh assesses whether a settling door can be repaired (new weatherstripping, hardware adjustment, threshold seal) or whether full replacement is the right recommendation.
Wood Door Maintenance Failure on West-Facing Gresham Entries
West and southwest-facing entry doors in Gresham face the prevailing Pacific storm track directly — sustained driving rain exposure during Gresham's long wet season. Original solid wood doors on these entries that have not been refinished on schedule have typically experienced significant UV and moisture damage. Paint failure at the bottom of the door allows moisture absorption into the end grain, which swells and cracks the door stile. Fiberglass is the practical replacement choice for these exposures.
What VResh Actually Does on a Gresham Entry Door Replacement
Entry door installation done correctly involves more than setting a new door in the existing opening. Here is what happens on every VResh installation in Gresham.
Full Removal and Rough Opening Inspection
Complete removal of the existing door unit, frame, threshold, interior casing, and exterior trim to expose the full rough opening. Inspect all four sides of the rough opening — sill, header, and jambs — for moisture damage, rot, and deteriorated flashing.
What VResh Finds When Removing Gresham Entry Doors
- Sill plate rot — the most common finding. Absent sill pan over 30–40 years means water has been pooling in the rough sill at every rain event. The rough sill plate below the threshold is typically soft to compromised on the majority of original-door removal projects on Gresham homes built before 1985.
- Missing head flashing — original door installation without any kickout piece above the rough opening. Water has been running into the rough framing from above the door for decades.
- Rotted jack studs — on doors with the most extensive moisture exposure, the framing on both sides of the rough opening is compromised from sustained saturation.
- Lead-painted surfaces on surrounding trim, siding, and rough opening framing — on pre-1978 Gresham homes, EPA RRP protocols apply from the first day of door removal.
Structural Repair and Lead Protocols
Replace compromised sill plate, sister or replace damaged jack studs, and ensure the structural rough opening is sound before the new door unit goes in. For pre-1978 Gresham homes: follow full EPA RRP protocols throughout — containment, wet work practices, thorough cleanup, and written documentation at project completion.
Sill Pan and Head Flashing
Install a formed sill pan at the threshold — the step that prevents the threshold rot we described above. Install head flashing above the door opening, integrated into the wall drainage plane — the step that prevents water from running into the rough framing from above.
The Two Steps That Prevent the Next Entry Door from Rotting at the Frame
- Sill pan flashing: a formed tray at the base of the rough opening that captures any water that gets past the threshold and directs it to the exterior. Without a sill pan, every door — regardless of how good it is — will eventually allow water into the rough sill. This is the most commonly skipped step on budget entry door installations.
- Head flashing: a kickout piece above the door opening — integrated into the WRB — that directs water from the wall surface away from the door opening rather than into the rough framing. Absent head flashing is the source of the water entry above the door that homeowners eventually see as staining or soft drywall on the interior.
Door Installation, Air Sealing, and Trim
Install the prehung door unit plumb, level, and square. Test operation before any trim is installed. Fill the gap between the door frame and rough framing with low-expansion window-and-door foam — proper air sealing makes a measurable difference in drafts and energy performance. Install exterior casing back-primed and caulked. Install interior casing, threshold, and all hardware. Test all locks and operation. Walk through with the homeowner.
Entry Door Materials for Gresham Homes
VResh installs steel, fiberglass, and wood entry doors. Here is the honest assessment of which is right for specific Gresham applications:
Fiberglass — Best Choice for Most Gresham Entries (especially west/southwest-facing)
Fiberglass doors do not dent, do not rust, do not swell from moisture, and hold their finish significantly longer than wood. Therma-Tru's fiber-classic line provides a wood-grain texture that is visually convincing — the practical choice for Gresham Craftsman and traditional homes where wood character matters but maintenance commitment is a concern. For west and southwest-facing Gresham entries with direct rain exposure, fiberglass is the right specification. Cost range: $1,800–$5,000+ installed.
Steel — Best Value, Best Security
Steel doors provide excellent security and strong energy performance from a foam-insulated core. The most cost-effective option in the mid-range price category. Steel is susceptible to denting and, if the finish coat is breached, surface rust — proper paint maintenance prevents this. A good choice for Gresham rental properties, north and east-facing entries with less direct rain exposure, and applications where security and cost are the primary drivers. Cost range: $1,200–$3,500 installed.
Wood — For Gresham's Craftsman and Historic Downtown Homes
Real wood entry doors provide the most authentic character for Gresham's historic downtown Craftsman homes and older bungalows. Available in mahogany, fir, and oak. Require refinishing every 2–5 years on south and west-facing entries. For Gresham homeowners who value architectural authenticity and are willing to commit to maintenance, a properly installed and maintained wood door is the right choice. Cost range: $3,000–$8,000+ installed.
Entry Door 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 Entry Door 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 the 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.
