Every door type. Properly installed.
From a single entry door to a full patio door system — we install all exterior door types, sized to your opening, finished to match your home.
Entry Doors
Single and double entry door systems in fiberglass, steel, and solid wood. The entry door is the most visible exterior element on your home and the primary weatherproofing barrier at grade level — threshold condition, weatherstripping quality, and frame integrity all directly affect how well the house seals against Oregon rain and cold. We assess all three at the estimate.
Sliding Glass Doors
Two or three-panel sliding patio door systems for deck and backyard access. Track condition, roller quality, and glass seal integrity all degrade over time — original 1980s–90s sliding glass doors in Tigard, Beaverton, and Gresham ranches are commonly past their useful life. We replace the full door unit including the frame, track, and threshold for a clean operating system that seals properly.
French Doors
Double door sets with glass panels — hinged outward or inward for deck, patio, and garden access. Adds architectural character to rear and side entries. Available in fiberglass and wood-clad styles. Proper weatherstripping on both active and passive panels is critical — we spec door sweeps and compression seals that hold through Oregon's prolonged wet seasons.
Storm Doors
A secondary door installed in front of your primary entry door for additional weatherproofing, ventilation, and energy performance. Storm doors add an air buffer that meaningfully reduces heat loss in winter — particularly valuable on north-facing or wind-exposed entries. Available in full-view glass and retractable screen options. Installation includes proper frame alignment with the existing entry door unit.
Bi-Fold & Multi-Slide
Folding door systems that open wide to create seamless indoor-outdoor connections — increasingly popular in newer West Linn, Happy Valley, and Lake Oswego remodels. Multi-slide systems stack multiple panels to one or both sides. These are complex installations that require precise rough opening preparation, level threshold installation, and properly sized structural headers. We assess structural requirements at the estimate.
Door with Sidelites
Entry door flanked by one or two narrow fixed glass panels — adds light to dark entryways and architectural presence to formal fronts. Common in craftsman, colonial, and contemporary homes across Lake Oswego, Beaverton, and the older Portland neighborhoods. The sidelite frames are part of the door unit and require the same flashing attention as the door itself — we treat them as a single weatherproofing system.
The Hidden Problem
Frame rot — the most common door problem that nobody talks about.
The door itself is rarely the only problem. In Oregon's climate, the most common failure pattern on exterior doors isn't the door — it's the wood frame and threshold around it. Water pools at the threshold. The door sweep fails. Moisture enters the bottom of the jamb. Over months and years, the wood at the base of the door frame softens, and eventually the door unit starts to rack, stick, and lose its seal.
Installing a new door into a rotted frame is a waste of money. Within a few years the same moisture problems return, the new door starts to operate poorly, and you're back to square one. We inspect the frame and threshold on every door estimate — probing the sill, checking the bottom jamb, and assessing how much of the frame is compromised. If there's rot, we scope it into the written estimate and repair it before the new door goes in.
This is more work and it adds to the cost. But it's the right way to do a door replacement, and it's the only way the new installation holds up for the 20+ years it should.

Door Materials
Choosing the right door material for Oregon.
Each door material handles Oregon's moisture, temperature cycles, and UV exposure differently. Here's an honest comparison.
Fiberglass
Therma-Tru, Masonite, ProVia
The best all-around door material for Oregon homes. Fiberglass won't rot, warp, or rust — the three main failure modes for exterior doors in our climate. Can be textured to look like wood grain and stained or painted. Excellent insulating value. Our recommendation for most entry door replacements across the Portland metro.
Steel
Therma-Tru, Stanley, JELD-WEN
The most affordable option with excellent security performance. Good insulating value. Vulnerable to surface rust if the finish is compromised — a scratch or dent that breaks the coating allows moisture to get under the skin in Oregon's climate. Best suited for protected entry locations not directly exposed to rain. Paintable but not stainable.
Wood
Douglas fir, mahogany, oak
The premium option for homes where architectural authenticity matters — historic Oregon City Victorians, Craftsman homes in Portland's Irvington neighborhood, and period-correct restorations. Genuine wood can be custom-milled to match any profile. Requires painting or sealing every 5–7 years and is vulnerable to rot at the threshold if not properly maintained. We recommend wood only where the aesthetic value justifies the maintenance commitment.
Our Process
How a door project works with OJB.
From first call to finished install — here's exactly what to expect.
Free on-site estimate
We measure the opening, probe the frame and threshold for rot, check how the existing door operates, and discuss style and material preferences. Frame rot repair is scoped into the written price upfront — no additions mid-project when we open the frame.
Door selection & order
We specify a door unit sized to your opening and matched to your home's architecture. Standard pre-hung door units typically arrive within 1–2 weeks. Custom sizes, glass configurations, or specialty materials take longer — we confirm the timeline at the estimate.
Frame prep & rot repair
Old door and frame removed. Rough opening inspected — any rot in the sill, jambs, or structural framing repaired before the new unit goes in. Threshold flashing installed. House wrap lapped correctly over the opening. The rough opening is right before the new door touches it.
Install, weatherstrip & test
Door set plumb and level, fastened to manufacturer specs, shimmed correctly in the opening. Weatherstripping, door sweep, and threshold adjusted for a complete seal. Hardware and deadbolt installed. Full operation test before we call it done — opens smoothly, latches firmly, seals tight.

Why OJB for Doors
Built on trust. Sealed against Oregon winters.
We fix the frame before the door goes in
Installing a new door into a rotted frame is the most common door replacement mistake in Oregon. The new door looks fine for a year or two — then it starts sticking, the seal degrades, and you're dealing with the same moisture problems again. We probe the frame and threshold at every estimate, scope any rot repair into the written price, and fix the problem completely before the new unit goes in.
Frame-first approachWeatherstripping spec'd for Oregon's rain season
Not all weatherstripping is equal. We specify compression seals and door sweeps rated for sustained moisture exposure — the kind that hold up through Oregon's October–May wet season, not just a dry summer installation. Threshold seals, head weatherstrip, and side jamb compression seals are all part of a complete installation. We test the seal before we leave every job.
Complete weatherproofingWritten price — no surprises when we open the frame
Opening a door frame can reveal more rot than was visible from outside. We look carefully at the estimate, probe suspect areas, and include frame repair in the written price before we start. The number you approve is the number on your final invoice — even if the rot goes deeper than it looked. We plan for what we find, not what we hope to find.

FAQ
Common door questions.
Not necessarily. A door that sticks or won't latch easily usually indicates one of three things: the frame has shifted from moisture absorption at the threshold, the hinges have settled and need adjustment, or the house has experienced minor settling that's racked the door frame. We diagnose the specific cause at the estimate — in some cases a hinge adjustment or threshold repair fixes the problem without replacing the full unit. If the frame has significant rot, replacement is the right call and we'll tell you that clearly.
Fiberglass is our consistent recommendation for the Portland metro. It doesn't rot, warp, or rust — the three main failure modes for exterior doors in Oregon's climate. It can be textured to look like wood grain and either stained or painted. It insulates significantly better than steel and requires almost no maintenance. Steel is a sound second choice where budget is the primary driver and the door location is protected from direct rain exposure. Wood is appropriate for period-correct restoration where architectural authenticity matters more than long-term maintenance cost.
The most reliable test is to press firmly on the wood at the bottom of the door frame with a screwdriver or your thumb. Sound wood resists; rotted wood will dent or feel spongy. Other signs include paint that peels repeatedly at the threshold area despite repainting, visible discoloration or staining at the frame base, and any soft spots when you run your hand along the bottom of the jamb. We do this check on every door estimate — it takes two minutes and it's the difference between a door replacement that lasts 20 years and one that has problems in three.
Like-for-like door replacement in the same opening generally doesn't require a permit in most Portland metro jurisdictions. Permits are typically required when you're changing the size of the opening, adding a door where there wasn't one before, or making structural changes to the wall. We determine permit requirements at the estimate and handle any necessary applications.
Yes — if the existing frame is in good condition, we can install a new door slab into the existing frame (called a door slab replacement). This is less expensive and less disruptive than a full pre-hung unit replacement. However, we'll only recommend this approach if the frame is genuinely sound — no rot, plumb and level, with good weatherstripping grooves. If the frame has any compromise, full pre-hung replacement is the better investment. We'll assess honestly at the estimate.
Sliding glass doors that operate stiffly usually have worn rollers — the wheels the door rides on in the bottom track. In many cases roller replacement resolves the problem without replacing the full unit. However, if the door is also showing failed glass seals (foggy between panes), significant track damage, or is original to a 1980s–90s ranch home where everything else is aging out, full replacement is often more cost-effective than roller repair on a unit that's already near end of life. We'll give you an honest assessment and both options at the estimate.
