The one opening
that has to hold
and look like this.

Not the glass alone. It is an assembly — leaf, frame, glazing, anchors and anchor spacing — tested together and approved as a unit for particular sizes and substrates. Install the same door with the wrong anchors and it is no longer the assembly that was approved. That is why we treat the installation detail as the product rather than the door.

For replacing an exterior door in this region, generally yes, and the approval documentation for the specific product goes in with the application. We submit, track and answer corrections, and we attend the inspection. Review durations are set by each municipality.

Almost always. The frame is part of the rated assembly, so reusing an old frame and hanging a new leaf in it does not give you a rated door. The buck behind it often needs replacing as well, and that is only visible once the old frame is out.

The product approval for what was installed, the permit and the signed-off inspection. Keep all three: they are what an insurer or a buyer's inspector will ask for, and reconstructing them years later is difficult.

The physical work on a straightforward opening is short. What sets the overall timeline is product lead time and permit review, neither of which we control. We will give you a realistic sequence rather than a single number.

Generally no, if you want a rated assembly. The glazing is part of what was tested. What we can usually do is match the pattern in a laminated impact unit, which is what several of the doors in the portfolio above are.

They solve the same problem differently. Impact doors are permanent, need nothing done before a storm and look like the house; shutters cost less up front and have to be deployed. Most people who have deployed shutters once in the rain at 6am reach a view about this quickly.

Usually noticeably, yes — laminated glass damps sound well, and that is often the benefit people comment on first. It is a side effect rather than a rating, so we would not put a number on it.

They can be done and several in the portfolio above are. Expect longer lead times and a higher price: the frame is fabricated to the curve and the buck and sealing detail have to follow it continuously.

Very little, but not none. Rinse the sill and clear the weep holes, fresh-water rinse the frame if you are near the coast, and check the weatherstrip compresses evenly once a year. Blocked weeps are the most common cause of a door that appears to leak.

Usually. Matching the frame finish and the glazing across doors and windows is what makes an elevation read as designed rather than as replaced piecemeal — the portico frame in the portfolio above is an example.
