How long does a typical custom window replacement take per window?

A single insert replacement can often be done in a few hours, while full-frame replacement with rot repair or flashing work can take the better part of a day per window. Whole-house jobs are usually scheduled over several days to keep openings weather-protected overnight.

What should I ask a contractor to prove they're licensed and insured before hiring them for window work?

Ask for their Washington state contractor license number and confirm it's active on the L&I website, and ask to see proof of liability insurance directly rather than taking their word for it. A legitimate contractor will provide both without hesitation.

Does it matter if my new windows are vinyl versus fiberglass versus wood-clad?

It matters mainly for long-term maintenance and how the frame handles moisture and temperature swings near the water — vinyl and fiberglass generally resist salt air and moisture better with less upkeep than wood-clad options. The right choice depends on your budget, your home's style, and how exposed that particular wall is.

What's the difference between a window's U-factor and its SHGC rating, and does it matter here?

U-factor measures how well the window resists heat loss, and lower is better for our cooler, wet climate. SHGC (solar heat gain coefficient) matters less here than in sunnier climates, but a moderate rating still helps balance winter warmth against summer glare on south- and west-facing walls.

Since Point Roberts is only reachable by land through Canada, does that affect scheduling or material delivery for a window project?

Yes — material orders and any follow-up trips need to be planned around that crossing, which is why a crew already familiar with working in Point Roberts can avoid the delays a less-experienced outside contractor might run into. We factor that into scheduling from the start rather than after a delay happens.

Custom Windows for Point Roberts Homes: Built for Salt Air & Rain

Why Point Roberts Windows Wear Out Faster Than You'd Expect

Point Roberts sits on open water on three sides, which means homes here take a different kind of weathering than a house ten miles inland in Whatcom County. Salt-laden air moves through screens, settles on frames, and works into hardware year-round — not just during storms. Add the Pacific Northwest's long wet season, where driving rain comes in sideways off the water, and you've got two forces working against a window at the same time: corrosion from the outside in, and moisture intrusion from the inside out.

Then there's moss season, which in this part of Whatcom County can run most of the year on shaded or north-facing walls. Moss and mildew hold moisture against trim and sills far longer than open sun-exposed siding would, which accelerates rot around window openings that aren't detailed correctly. None of this means Point Roberts homes need exotic materials — it means the ordinary parts of a window installation (flashing, sealant, frame material, hardware) have to be done right, every time, because there's less margin for a shortcut here than in a drier climate.

What a Correct Custom Window Job Actually Involves

"Custom" windows just means the unit is built to fit your actual opening rather than pulled off a shelf in a stock size — common on older Point Roberts homes where openings have settled or were never standard sizes to begin with. A correct job is more than ordering the right dimensions. It includes:

Accurate field measurement of each opening, accounting for out-of-square or out-of-level conditions common in older framing
Frame material and glass package selected for the specific wall's sun, wind, and moisture exposure
Removal of the old unit down to sound framing, with any rot or water damage repaired before the new window goes in
Proper flashing and sill pan work integrated with the existing water-resistive barrier and siding
Correct shimming, fastening, and insulation of the gap between frame and rough opening
Interior and exterior trim and sealant work that sheds water rather than trapping it

Skip any one of these and you can end up with a window that looks fine for a year or two, then starts fogging between panes, sticking on its track, or letting water into the wall cavity where you can't see it.

Choosing the Right Frame Material for a Waterfront Exposure

There's no single "best" window material for every home — the right choice depends on exposure, budget, and how the rest of the house is finished. For Point Roberts specifically, salt air and moisture resistance matter more than they would for the same house set back from the water.

Material	Salt air / corrosion behavior	Maintenance	Typical cost position
Vinyl	Won't corrode; UV can chalk over many years	Low — occasional cleaning	Lowest to mid-range
Fiberglass	Very stable in salt and moisture; dimensionally matches glass expansion	Low	Mid to upper-mid
Aluminum-clad wood	Exterior clad resists weather well; any exposed fasteners or seams need attention near salt air	Moderate	Upper
Solid wood (interior or fully protected only)	Poor in direct salt/moisture exposure without heavy protection	High	Varies

Hardware matters as much as frame material. Locks, hinges, and cranks that aren't rated for coastal exposure will corrode and bind well before the window itself fails — ask specifically what hardware finish is being used, not just what the frame is made of.

Full-Frame Replacement vs. Insert Windows

Custom window work on an older home usually comes down to one of two approaches, and the right one depends on the condition of what's already there, not just preference.

Insert (pocket) replacement

The new window goes inside the existing frame, which is faster and less disruptive to siding and trim. This works well when the existing frame is still solid, square, and dry. It's not the right call if there's hidden rot, since it seals moisture problems in rather than addressing them.

Full-frame replacement

The old window and its frame come out entirely, exposing the rough opening for inspection and repair. This is slower and costs more but is the honest choice whenever there's any sign of water damage, soft wood, or an opening that's shifted out of square — all of which show up more often on Point Roberts homes with direct rain exposure than on more sheltered inland properties.

A contractor who tells you every window needs full-frame replacement, or that inserts are always fine, isn't looking closely enough at your specific openings. It should be assessed window by window.

Water Management: The Part You Never See Again

Once trim goes back on, the flashing and sill pan underneath are invisible — which is exactly why they're the most important part of the job. In a driving-rain climate, water will find any gap in the water-resistive barrier around a window opening. Correct water management means:

A sloped sill pan that directs any water that gets past the glass back outside, not into the wall
Flashing tape or membrane integrated in the right shingle-lap order with the house wrap so water flows down and out, not behind the barrier
Head flashing above the window that sheds water clear of the top of the frame
Sealant used only where it belongs — sealant is not a substitute for proper flashing, and over-sealing a window can trap moisture instead of keeping it out

This is the step that separates a window that lasts fifteen-plus years from one that causes a rot repair behind the trim five years in. It's also impossible to verify from the street after the job is done, which is why it matters who's doing the work, not just what brand of window they're installing.

Moss, Mildew, and North-Facing Walls

On shaded elevations — north walls, areas under tree cover, spots that don't get much direct sun — moss and mildew growth can start on trim and siding around windows within a season or two if the surfaces stay damp. This doesn't damage the window glass or frame directly in most cases, but it does hold moisture against wood trim and caulk lines longer, which shortens the life of both. Where we're installing or trimming out windows on these exposures, we pay attention to drainage paths and trim details that let surfaces dry out between rain events, rather than assuming the same detailing that works on a sun-exposed south wall will hold up the same way here.

Our Process

On-site assessment — we look at each opening individually, not just count windows from a photo or a general estimate
Honest recommendation — insert vs. full-frame, material options, and what we'd do on our own house, explained in plain terms
Written estimate — clear line items, no vague allowances
Scheduling around weather — window replacement means an open wall for a period of time, so we plan installs for dry stretches where possible
Installation with opened-up inspection — any rot or water damage found once the old unit is out gets addressed before the new window goes in, and we tell you what we found
Final walk-through — operation, sealing, and trim checked with you before we call it done

Why It Matters That We Already Work in Point Roberts

Point Roberts is a geographic exclave — the only way in by land is through Canada, and that has real, practical effects on a construction project that a lot of contractors from elsewhere don't plan for. Material deliveries, extra trips for a forgotten part, and crew scheduling all have to account for that crossing, and a crew unfamiliar with it can turn a one-day fix into a multi-day delay. A crew that regularly works in Point Roberts plans material orders and scheduling around that reality up front, so your project isn't the one that stalls because someone has to make an unplanned run.

Beyond logistics, familiarity with local exposure conditions — which walls take the worst of the wind and rain, where moss builds up fastest, how salt air has already treated the hardware on similar homes nearby — means fewer surprises once we open up your window openings. Whatcom County permitting and inspection still apply here the same as anywhere else in the county, and we handle that as part of the job.

Before You Sign a Window Contract

Is the quote based on an in-person measurement of each opening, or an estimate from a phone call?
Does the proposal specify insert vs. full-frame replacement for each window, and why?
What frame material and hardware finish is actually being installed — get it in writing, not just a brand name
Does the contractor describe how flashing and sill pans will be handled, or only mention caulking?
What happens if rot or water damage is found once the old window comes out — is that priced separately, and how?
What's covered under warranty, and for how long — on both the window unit and the installation labor?

If a contractor can't answer these clearly before the contract is signed, that's worth noticing.
