Why Door Seals Matter
UPVC and composite doors are designed to create a tight seal when closed. The seals compress against the frame, blocking out draughts, noise, moisture, and dust. When they wear down, crack, or lose flexibility, you’ll often notice:
-
Cold air entering the room even with the door shut
-
Higher energy bills due to lost heat
-
Increased noise from outside
-
Condensation, leaks, or damp patches near the door
-
Doors that rattle or feel loose in windy conditions
A door without a working seal isn’t just uncomfortable — it’s also less secure and less efficient.
Our Door Seal Repair Service
At Repair UPVC, we don’t believe in one-size-fits-all solutions. Every door, frame, and seal type is slightly different, which is why we carry a wide range of replacement seals and tools to match the original as closely as possible. Our service includes:
-
Inspection & Diagnosis – We carefully check your existing seals to identify wear, damage, or incorrect fitting.
-
Seal Replacement – We supply and fit new, high-quality seals that restore proper compression and insulation.
-
Frame & Hinge Adjustment – Many seal issues are caused by misaligned doors. We adjust hinges and frames to ensure the seal makes full, even contact.
-
Draughtproofing & Weatherproofing – We test the door thoroughly after repair to ensure it shuts firmly, with no gaps for air or water to pass through.
-
Maintenance Advice – We’ll show you how to keep seals in good condition, extending their lifespan.
Common Door Seal Problems We Fix
-
Flattened Seals – Over time, seals lose their spring and fail to press tightly against the frame.
-
Cracked or Split Seals – Exposure to weather and use can cause seals to break down.
-
Shrinking Seals – Some rubber seals shrink with age, leaving gaps at the corners.
-
Incorrect Seal Types – We often find seals that were poorly matched to the door and never sealed properly.
-
Misaligned Frames – Even a good seal won’t work if the door is out of alignment.
