How we handle window mastic in Church Norton
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. Common call-outs are for cracked sealant at the sill ends and black, perished sealant on frames, across uPVC windows, composite doors and window sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Church Norton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Church Norton homes and the weather
Church Norton is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as The Academy, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Bognor Regis station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Local landmarks in Church Norton
Church Norton’s nearest station is Bognor Regis station, roughly 4.9 miles north-east of the centre. A little further out are Selsey Lifeboat Museum (1.5 miles south) and Bognor Regis War Memorial Hospital (5.1 miles north-east).
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. Somewhere as small as Church Norton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.

Church Norton questions
Do you work for landlords with property near Bognor Regis station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Church Norton within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Is the work guaranteed?
Yes. Our 12-month guarantee covers every job.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Can you do the inside joint as well?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Signs you need window mastic in Church Norton
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.
People generally contact us when they notice something like this:
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
If you live in an older home near St Wilfrid's Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
