Windows Built for Conway's River-Delta Climate
Conway sits low in the Skagit River delta, close enough to Skagit Bay that salt-laden marine air is a daily fact of life, and close enough to farmland and river flats that humidity lingers long after a storm passes. That combination is hard on windows in ways that homeowners further inland rarely deal with. Salt air accelerates corrosion on hardware and metal components. Driving rain, pushed sideways by wind off the water, tests seals and flashing in a way that a light, straight-down rain never does. And the long, wet moss season that defines a Skagit County winter keeps wood and vinyl surfaces damp for weeks at a stretch, which is exactly the environment failing seals and soft frames need to turn into real problems.
None of this means Conway homes need exotic materials or gimmicks. It means the basics — frame material, glass package, and especially installation and flashing detail — matter more here than they would in a drier climate. A window that's a perfectly fine choice in eastern Washington can be the wrong choice fifteen miles from open water.

What We Mean by "Custom" Windows
"Custom" doesn't mean unusual shapes or high-end finishes, though we do those too. Most of the custom window work we do in Conway is custom in the sense that matters most: built to the exact opening in your specific house, not the nearest stock size with shims and foam filling the gap.
Where custom sizing matters most
Older Conway homes — farmhouses, mid-century ranches, and older rebuilds near the flats — often have openings that have shifted slightly over decades of settling, or were framed to dimensions that don't match anything on a big-box shelf. Trying to force a stock window into an opening that's an inch off in either direction usually means more gap to seal, which means more places for wind-driven rain to find a way in. A properly sized custom unit closes that gap at the manufacturing stage instead of asking caulk and trim to cover for it later.
New construction vs. retrofit/replacement
We install both. New-construction windows have a nailing fin and get integrated with the house wrap and flashing during framing — the right approach for additions or full re-siding projects. Retrofit (or "insert") windows fit inside the existing frame and are common for straight replacements where the surrounding wall and siding are staying put. Both can be done correctly or poorly; the difference is almost always in the flashing and sealing detail, not the window itself.
Signs Your Current Windows Are Past Due
Window failure in a marine climate rarely announces itself with a dramatic leak. It shows up gradually, and homeowners often adjust to it without realizing how much it's costing them in comfort and energy.
- Fogging or a permanent haze between panes — the seal has failed and the gas fill (or plain air) has been compromised
- Visible condensation on the inside of the glass during cold, damp weeks
- Soft or discolored wood on the interior sill or exterior trim around the frame
- Windows that are noticeably harder to open, close, or lock than they used to be
- A draft you can feel with your hand near the frame on a windy day
- Chalky, pitted, or corroded hardware — common on older aluminum-framed windows near the water
- Rooms near exterior windows that feel colder or damper than the rest of the house
Any one of these on its own might just mean a resealing job. Several at once, especially combined with soft trim, usually means the window and the flashing behind it need to come out.
Frame Material Comparison for a Marine, Wet Climate
There's no single "best" window material — there's a best material for this house, this exposure, and this budget. Here's how the common options actually hold up in Conway's conditions.
| Material | How it handles salt air & moisture | Maintenance | Typical lifespan |
|---|---|---|---|
| Vinyl | Won't corrode or rot; good baseline performance | Low — occasional cleaning | 20–30 years |
| Fiberglass | Very stable in wet/humid swings, resists warping | Low | 30–40 years |
| Wood-clad | Exterior clad face resists weather; interior wood needs protection from moisture intrusion | Moderate — watch seals and joints | 20–30 years with upkeep |
| Aluminum | Prone to corrosion and pitting in salt air over time; conducts cold, prone to interior condensation | Moderate to high | Varies widely |
Our default recommendation for most Conway homes is vinyl or fiberglass, simply because they don't give salt air or standing moisture anything to work with over the long run. Wood-clad is a fine choice when the look matters and the exposure is moderate — a covered porch or a wall that isn't taking direct weather — but it's not our first pick for a wall that catches driving rain straight on. We'll walk your specific exposures with you rather than recommend one material blanket-wide.
Glass packages worth discussing
Double-pane, low-E glass with argon fill is the standard for good reason — it balances cost and performance well for this region. Triple-pane adds meaningful sound dampening and a small efficiency bump, which some homeowners near busier roads or with west-facing exposure to weather find worth the extra cost. We'll give you the honest trade-off for your specific situation rather than upsell triple-pane across the board.
How Our Installation Process Works
The window itself is maybe a third of the job. The rest is what happens around it.
- On-site assessment. We look at the existing frame, sill condition, siding type, and exposure — a wall that takes direct wind-driven rain gets treated differently than a sheltered one.
- Precise measurement. Custom units are ordered to the actual opening, accounting for any out-of-square settling common in older homes.
- Removal and inspection. Once the old window is out, we check the framing and sheathing behind it for hidden rot or moisture damage before anything new goes in. This is often the point where a "just replace the window" job turns into a "we found something worth fixing first" conversation — and we'll always tell you before proceeding.
- Flashing and moisture barrier work. Proper sill pan flashing, integration with the house wrap or building paper, and correctly lapped flashing tape — done in the right order, not just caulked over.
- Setting, shimming, and fastening the window plumb, level, and square, per manufacturer spec.
- Insulating the gap between frame and rough opening — low-expansion foam or backer rod, not stuffed fiberglass that leaves voids.
- Exterior and interior trim, sealant, and cleanup. We test operation and check the seal before we consider the job done.
Flashing and Moisture Management: The Part Nobody Sees
This deserves its own section because it's the single most common source of window-related problems we find in this area — and it's almost never the window's fault. A quality window with sloppy flashing will leak. A mid-grade window with correct flashing usually won't.
In a climate where rain regularly comes in sideways off the bay, water management at the window opening has to assume wind-driven moisture will reach the flashing plane, and give it a way out. That means a sloped sill pan so water drains outward instead of pooling, flashing tape lapped shingle-style (upper pieces overlapping lower ones, never the reverse), and a clean tie-in to the house's water-resistive barrier. Skip any one of these steps and the failure might not show up for a year or two — by which point it's showing up as rot in the framing, not just a drafty window.
Choosing a Window Contractor Who Actually Works Conway
A crew that mostly works drier inland areas can do a technically fine window install and still get the flashing detail wrong for a marine-exposed wall, simply because it's not the failure mode they see day to day. A crew that regularly works Skagit County's low-lying, weather-exposed communities has already seen what happens when that detail gets skipped, and builds the job around avoiding it from the start.
What that experience actually looks like on the job
- Recognizing which walls on a Conway property take the worst of the wind-driven rain and treating those openings with extra care
- Knowing which frame materials hold up and which ones create ongoing maintenance headaches near open water
- Catching hidden rot or moisture damage during removal instead of covering it up with a new window
- Being straightforward when a window doesn't need full replacement — sometimes a reseal or hardware repair is the honest answer
- Standing behind the installation, not just the manufacturer's product warranty
Living With Moss Season: An Upkeep Checklist
Good installation buys you decades of trouble-free performance, but a little seasonal attention — especially heading into and coming out of the wettest months — keeps it that way.
- Wipe down frames and sills periodically to clear salt residue and organic buildup before it holds moisture against the surface
- Check and clear weep holes on the exterior frame so water can drain instead of pooling
- Inspect exterior caulk lines each fall for cracking or separation and touch up before the wet season sets in
- Look for moss or algae starting to establish on sills or trim and remove it early — it holds moisture against the surface once it takes hold
- Test locks and operation once or twice a year; stiff hardware is often the first sign of corrosion starting
- Keep gutters and downspouts clear so runoff isn't sheeting directly across window openings
What Affects the Cost of a Window Project
We don't post fixed prices because every house and opening is different, but the main cost drivers are consistent across almost every job we quote in this area.
| Factor | Why it moves the price |
|---|---|
| Frame material | Vinyl is typically the most affordable; fiberglass and wood-clad cost more up front |
| Glass package | Double-pane low-E is standard; triple-pane and specialty coatings add cost |
| New construction vs. retrofit | New-construction installs involve more siding and trim work around the opening |
| Hidden repairs | Rot or moisture damage found behind an old window adds framing repair before the new one goes in |
| Number and size of openings | Larger or unusually shaped windows require more custom fabrication |
| Access and site conditions | Second-story or hard-to-reach openings take more time and equipment |
The only way to get an honest number is to have someone look at the actual openings — quotes based on square footage guesses alone tend to be wrong in one direction or the other.
