Burlington Building New in Conway? The Windows Have to Be Right the First Time
Conway sits low in the Skagit River delta, close enough to Puget Sound and the tidal flats that salt-laden air is a daily fact of life, not an occasional nuisance. If you're framing a new home or an addition here, the window installation is one of the few construction steps you genuinely cannot fix cheaply after the siding and trim go on. A new-construction window sets into a rough opening before the weather-resistive barrier and cladding close around it — get the flashing sequence or the product selection wrong, and the mistake gets buried for years until it shows up as rot, mold, or a stuck sash.
This page covers what we do specifically for new-construction window installs in the Conway area: the product choices that hold up to this climate, the flashing details that actually keep water out, and the process we follow on a framed opening before anyone touches paint or siding.
What Conway's Climate Actually Demands From a Window
Three things define window performance out here, and they're all working against the building at the same time for much of the year:
- Salt air corrosion. Metal window components — screws, cladding fasteners, weep hardware, balance systems — corrode faster this close to saltwater. Cheap or mismatched hardware finishes are usually the first thing to fail.
- Driving rain. Skagit County storms often come with wind-driven rain that hits windows at an angle, not straight down. That means the flashing and sill pan have to handle water pushed sideways and upward under wind pressure, not just water running off a sill.
- A long moss season. Cool, damp conditions for much of the year mean anything that traps moisture — poorly sloped sills, clogged weep holes, wood trim in constant shade — grows moss and organic buildup that holds water against the window and the wall assembly behind it.
None of this is exotic. It's ordinary Pacific Northwest weather, concentrated by Conway's proximity to open water and low elevation. A window that would be perfectly fine in a drier inland climate can underperform here if it's not detailed correctly.
Choosing Window Materials and Types for New Construction
On a new build, you get to pick the product and the opening size from scratch — there's no old frame dictating your options. That's an advantage worth using well. We steer new-construction Conway clients toward materials that handle sustained moisture and salt exposure without high maintenance demands.
| Frame Material | How It Handles This Climate | Maintenance |
|---|---|---|
| Vinyl | Won't corrode or rot; performs well against salt air and rain; seams and welds matter for long-term water tightness | Low — occasional cleaning |
| Fiberglass | Very stable in wet, temperature-swinging conditions; strong resistance to warping; holds paint well if color changes later | Low |
| Wood or wood-clad | Good appearance and insulation, but exposed wood needs consistent maintenance in a damp, moss-prone climate | Moderate to high |
| Aluminum | Strong and slim sightlines, but conducts cold and is more prone to condensation and corrosion near saltwater without thermal breaks | Moderate |
We're not telling clients a given material is bad — every one of these has legitimate uses. What we do is match the product to the exposure. A north-facing wall that stays shaded and damp most of the year is a different problem than a sheltered, sun-exposed elevation, and we'll say so plainly rather than push a single product on every opening.
Glass and Gas Fill
Double-pane, low-E, argon-filled glass is the baseline we install on new construction here — it meets Washington's energy code requirements and performs well in our cool, wet climate. For homes with more exposed elevations or larger window walls, triple-pane is worth discussing on a case-by-case basis, mainly for comfort and condensation resistance rather than dramatic energy savings.
Flashing and Water Management: Where New Windows Actually Fail
Almost every window failure we're called to repair on newer homes traces back to the same root cause: the flashing sequence, not the window itself. New construction gives you the chance to do this correctly from bare framing, and it's the part of the job that matters most in a climate like Conway's.
A correct install includes, in order:
- A sloped sill pan at the rough opening so any water that gets past the window drains back out, not into the wall cavity.
- Self-adhered flashing tape integrated with the weather-resistive barrier in the correct shingle-lap order — bottom, sides, then top — so water always drains over the next layer down.
- Proper sealant placement at the window flange, leaving the bottom flange unsealed or weeped per manufacturer instructions so incidental water can escape rather than pool.
- Head flashing or a drip cap above the unit to break the path of water running down the wall before it reaches the window.
- Backer rod and exterior sealant at the trim, sized and tooled correctly so it flexes with the building instead of cracking.
Skip or shortcut any one of these steps and the window can look fine for a year or two while water quietly works into the sheathing. We've opened up walls on newer Skagit County builds where the window itself was a good product — the flashing just wasn't done right.
Our New-Construction Window Installation Process
On framed openings, we work directly with the builder's schedule so windows go in at the right point in the sequence — after the weather-resistive barrier is up, before siding starts.
- Verify rough opening sizes against ordered window dimensions before delivery, catching framing errors while they're still cheap to fix.
- Install sloped sill pans and flashing tape in the correct order for the specific WRB system on the job.
- Set and shim each window plumb, level, and square, then fasten per manufacturer specs — this affects how smoothly sashes operate for the life of the window.
- Insulate the gap between the frame and rough opening with low-expansion foam or backer rod, avoiding over-filling that can bow the frame.
- Complete exterior flashing, head flashing, and sealant details before trim or siding closes around the opening.
- Walk every unit for operation, seal integrity, and hardware function before we consider the opening finished.
Cost Factors on a New-Construction Window Package
Every new build is different, so we quote against your actual window schedule rather than a flat per-opening price. The variables that move the number most are:
| Factor | Why It Matters |
|---|---|
| Frame material | Vinyl is typically the most economical; fiberglass and wood-clad cost more upfront |
| Number and size of openings | Large window walls or oversized units need heavier framing support and cost more per square foot of glass |
| Glass package | Standard low-E double-pane vs. triple-pane or specialty coatings |
| Elevation exposure | Openings facing prevailing wind and rain may warrant upgraded flashing details or products |
| Site access and scheduling | Coordinating with a build timeline still under construction is different from a retrofit on a finished home |
We'll walk your plans and give you a straightforward range once we know the window schedule — no inflated numbers to negotiate down from, and no lowball quote that leaves out flashing labor.
Energy Code and Performance Requirements
Washington's energy code sets minimum U-factor and performance requirements for new-construction windows, and your building department will check this at inspection. We spec products that meet or beat code minimums as a matter of course, and we can supply the NFRC labels and documentation your builder or permit file needs. In a climate with as many gray, damp days as Skagit County gets, a properly performing low-E glass package also makes a real difference in comfort and condensation control inside the home, not just on the utility bill.
Why a Crew That Already Works Conway Is Worth It
Conway isn't a big market, and that's exactly why local experience matters here. We know which elevations on a typical Conway lot take the worst of the wind-driven rain off the flats, how fast moss and algae build up on north-facing trim in this microclimate, and which flashing details hold up over a full wet season versus which ones we've had to go back and fix on someone else's work. That's knowledge you don't get from a crew that installs windows in a dozen different climates and treats every job the same.
We also coordinate directly with builders and framers on new construction, so window openings, flashing, and trim details are planned before drywall or siding makes changes expensive.
Keeping New Windows Performing Through Moss Season
A correctly installed window is close to maintenance-free, but a little seasonal attention extends its life in this climate:
- Clear weep holes and sill tracks of debris and moss buildup, especially on shaded elevations, before the wet season sets in.
- Check exterior sealant joints annually for cracking or separation and touch up as needed.
- Rinse salt residue off exterior frames and hardware periodically, particularly on sides of the house facing open water.
- Watch for slow-draining sills, which usually signal a clogged weep path rather than a failed window.
