Screen & Storm Door Installation on San Juan Island

Repairing a torn screen in an existing frame belongs on the door, window, and trim page. This page is the bigger version: a complete screen door or storm door unit, chosen for the opening and the exposure, cut to fit, and hung so it closes by itself and stays closed in a wind.

Fit is the whole difficulty, because island door openings are rarely square. A house on post-and-pier that has been settling since 1972 will commonly show a quarter to a half inch of difference across an opening’s diagonals, and older town houses on stone or brick foundations can be worse. A storm door sold as a 36-inch unit assumes a plumb, square, flat opening. So I measure both diagonals and the width at top, middle, and bottom, then fit the door to what is actually there: hinge rail set plumb rather than parallel to a leaning casing, the mounting flange shimmed and packed out, the latch-side expander and sill sweep adjusted last so the closed gap is even top to bottom. Done properly, an out-of-square opening still gets a door with a consistent shadow line. Done by the instructions, you get a door that binds at the top and gaps at the bottom.

Material and hardware selection is a coastal decision, and it is where most of the money is wasted out here. Mill-finish aluminum storm frames chalk and pit within a few seasons on a water-facing wall. Plain steel hinge screws driven into an aluminum frame set up galvanic corrosion in salt air and seize in place, so the door that needs adjusting in year three cannot be adjusted at all without drilling out fasteners. Stainless fasteners, anodized or well-coated frames, and closers with corrosion-resistant hardware cost more up front and are simply cheaper over ten years. On the most exposed doors, a well-built wood screen door in cedar or fir, finished on all six sides including the top and bottom rails, often outlives the aluminum options and looks like it belongs on the house.

Wind is the other thing storm door instructions do not account for. A south or southwest-facing door catching a December southerly will tear a single closer arm out of its bracket, and after that the door will rack itself out of square hanging on one hinge. Exposed doors get two closers, top and bottom, plus a wind chain sized to stop the door before it reaches the wall. Pneumatic closers also collect grit and salt on a beach-side door and stiffen up, so they get cleaned and adjusted rather than replaced on an annual basis.

There is a real thermal argument for a storm door in a lot of island houses, particularly the older ones with an original wood entry door that nobody wants to replace. A storm door adds an air gap and takes the driven rain off the primary door, which is often what is destroying the paint on the bottom rail. One warning that catches people: a full-glass storm over a dark-painted door on a south or west wall creates an oven between the two, and the heat will blister the finish on the door you were trying to protect. On those walls I use a vented storm, a screen-over-glass combination that can be left in the screen position through the summer, or a lighter finish on the primary door.

Screen choice is worth thirty seconds of conversation. Standard fiberglass mesh is fine on most openings. Aluminum mesh holds its shape better on a big door. Pet mesh is the answer where a dog leans on the lower panel, which is most doors here. Tighter no-see-um mesh helps in a shaded low-lying yard near standing water where the biting insects are worst in late spring. Deer are the other consideration on a garden-side door, since a deer investigating a screen at nose height will put a hole in ordinary mesh, and a kick plate or lower panel guard saves the door.

Retractable screens are the right product on sliders and on wide French or patio openings where a swinging screen door has nowhere to go. They roll away out of the weather, which matters here, and they suit a house that sits empty half the year. They need a straighter, cleaner opening than a hinged door does, so I check the track and jamb before I recommend one.

For second homes and rentals, the practical detail is timing. Screens go on in the spring before the season and can come down in October, and if the house is on a property care plan that swap is just part of the visit. A screen door left hanging through a winter of southerlies on an unoccupied house is how a good door becomes a bent door.
