Weather Sealing & Weatherstripping
Drafts, driven rain, bugs and energy bills leaking through the door. New seals, interlocks and sill work that make the door tight again.

A sliding door seals differently from every other door in the house: its panels meet on interlocking stiles, slide past brush seals and felt fins, and sit in a sill that wind-driven rain attacks horizontally. When the weatherstripping is worn — and sun, heat and freeze-thaw wear it steadily — the symptoms stack up: drafts you can feel, a room that will not hold its temperature, rain driven under the door in a real storm, bugs treating the gap as a driveway, and the whistle on a windy night.
We replace worn pile weatherstripping and fin seals, renew the interlock and meeting-stile seals, re-seal the frame perimeter, and address the sill — the channel where most water intrusion actually begins. The result is a door that closes with a soft, definite seal instead of a rattle.
What's included
- Pile weatherstripping and fin-seal replacement
- Meeting-stile and interlock seal renewal
- Frame perimeter re-sealing (interior and exterior)
- Sill and track drainage inspection and clearing
- Panel alignment so the seals compress evenly
- Water test at the end of the job, hose in hand

How it works
Our Process
Find the leaks
Daylight, drafts and water paths are traced around the whole perimeter — seals, interlock, sill and frame joints.
Renew the seals
Worn pile, fins and meeting-stile seals are replaced with the correct profiles for your door.
Fix the sill story
Drainage paths are cleared and the sill checked — sealing a drainage problem shut would make it worse, so order matters.
Water test
We hose the door down from outside. No water inside, no whistle, no daylight — that is the standard.
Questions
Weather Sealing & Weatherstripping — FAQs
Usually a combination: worn bottom seals, a sill whose drainage weep holes are blocked with years of debris, and wind-driven rain pushing against seals that no longer compress. Each has a fix, and the first job is identifying which combination your door has.
A sliding door is one of the largest openings in the house, and a worn seal leaks conditioned air around its entire perimeter, all day. A tight door is measurable — and the room beside the door simply feels better, which most owners notice before the bill does.
Pile seals typically give five to ten years, less on sun-blasted south and west doors. Sun and heat are the killers — the pile flattens, the fin cracks. It is inexpensive material; the skill is fitting it correctly so the door still slides freely.
Correctly fitted seals add a slight, definite resistance right at the closed position — that is the seal compressing, and it should feel like quality, not effort. If a door needs a shove to latch after sealing, the seals are wrong or the panel needs adjustment, and we do not leave it that way.
