Shoreline Window Pros provides professional french and hinged patio doors in Shoreline, WA for residential and commercial properties across north King County. A pair of hinged glass doors is the most attractive way out of a house and the hardest to weatherproof. Two leaves meeting with no fixed frame between them make a joint that has to seal against driven rain using a moving part.
That joint is the astragal: a vertical member mounted on one leaf, which the second leaf shuts against. On good units it carries a full-height weatherstrip, shoot bolts top and bottom that pin the inactive leaf into the frame and sill, and an adjustable strike so the seal can be tuned after the house moves. On cheap units it is a screwed-on strip with a magnet. Ask which you are buying.
The swing direction question has a real answer here, and it is not the usual one. Outswing doors seal better against driven rain because the wind pushes the leaves harder into their stops, and their sills shed water away from the house. Inswing doors are more common, easier to screen, and put the hinges inside where they cannot be attacked. On an exposed elevation with little overhang, we argue for outswing and we say why.
Overhang decides a lot of it. The postwar ramblers across Shoreline were generally built with deep eaves, and a door tucked under three feet of soffit is protected in a way that a door in a gable end or under a shallow modern roofline simply is not. We look up before we quote. Where there is real shelter, an inswing pair with a good sill is fine.
The sill is the component to spend on. Ask for an adjustable composite sill with a cap that raises and lowers on screws, because that adjustment is what lets us re-seat the seal a year later when the framing has settled. Under it goes the same pan detail we use everywhere: sloped bed, back dam, end dams and a drainage path onto the barrier, since our walls have no cavity behind the siding to do that work.
Glass and grille choices change the look completely. True divided lites with individual sealed units are expensive and thermally worse. Simulated divided lites, with a spacer bar inside the unit and bars applied to both faces, read correctly from a distance and keep one sealed unit per leaf. Flat grilles floating between panes look flat, because they are.
Interior french doors are a different, easier job with none of this water detail, and we fit those too. The only real considerations are the swing clearance, whether the opening needs safety glazing under the hazardous-location rules, and whether the header can carry a wider opening if you are enlarging it.
If you have existing french doors that drag, leak or will not latch, get them assessed before replacing. Hinge screws into a rotted jamb, a sagging leaf and a mis-set strike are all repairable, and the doors themselves are often the best part of the assembly.
Our licensed and insured team brings the right materials and equipment to every job — sill pan, back dam, head flashing, flush fin, nail fin, turned end dam — and backs the work with a written workmanship warranty. We serve Shoreline and nearby communities including Seattle, Edmonds, Lynnwood, Mountlake Terrace.

Materials, equipment and how we do french and hinged patio doors
The difference between french and hinged patio doors that lasts and french and hinged patio doors that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with sill pan, back dam, head flashing, flush fin, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Shoreline job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in north King County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Shoreline Chooses Shoreline Window Pros
- ✓We open one representative wall before quoting. Finding rusted drip caps or bare sheathing costs an hour up front and prevents the change order that otherwise lands halfway through the job.
- ✓Every opening gets a pan that slopes outward, dams at its interior edge and turns up at both jambs, in flexible flashing or formed metal. In a wall with no drainage cavity, that pan is the last line of defense and we do not skip it to hit a number.
- ✓Our quotes name the NFRC certified numbers, not marketing terms. Heat loss, solar gain, light transmission and air leakage are all printed on the sticker, and those four figures are what one bid should be compared against another on.
- ✓We stock and fit both flush-fin and full nail-fin units. That choice is made by what the wall can survive, not by which one our supplier is running a promotion on this month.
