San Dimas Windows & Doors, Sills Checked First
Before quoting an older San Dimas house, a level goes on every outside sill and threshold, since a sill that tips back toward the room sends water inward.
Before we quote an older San Dimas house, a short level goes on every outside sill and door threshold. A sill should pitch outward so rain runs off its nose. One that reads flat, or tips back toward the room, has either sunk with the framing under it or swelled from water it has held, and either way the opening needs work at the sill and below. That reading decides what each line of the quote covers.
Reading a flat or back-tipped sill
A flat sill lets water pool under the lower sash and at the joint on each end, where it soaks into end grain. A sill that tips inward sends water toward the wall, where it can wet the framing below. We probe the sill and the stud ends under it, and look inside for stains on the plaster under the window. Where only the sill has failed, a new one is milled with the right pitch and a drip groove. Where the framing has dropped, it is repaired before any new sill is set.
Thresholds and doors
A threshold that tips inward is how water reaches the floor framing under an exterior door. Where the level shows trouble, the old threshold comes up, the subfloor is checked, and a sill pan goes down that slopes to the outside with a raised back edge. The new threshold sits on that pan, and the landing outside is checked so it falls away from the house. Each door is then hung so its bottom seal meets the threshold evenly along its width, and the sweep clears the floor inside.

Windows & Doors in San Dimas: common questions
Sill pitch often settles it. A sash in a frame whose sill still sheds water can usually be restored with new putty, paint and cords. Where the sill has rotted or holds water, a new sill can be let into the old frame, and only a frame that has failed throughout calls for a new unit.
Where two windows sit side by side under one head casing, the post between them is part of the look. Ordering them as a factory-joined pair keeps that post slim. Sash proportions and pane layout are taken from the originals, and the shared head casing goes back up whole.
Permits in San Dimas come through the city, whose building staff review new windows, new exterior doors and changed openings. Repairs found by the sill check, such as new framing under a threshold, are inspected before they are covered, and energy labels and safety glass are checked on new units. Drawings and forms for the permit are prepared by us.
