About our window mastic in Weedon
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. Typical jobs include mastic that’s falling out in pieces and whistling draughts around closed windows, on composite doors, window sills and aluminium frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Weedon is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house in most cases. Somewhere as small as Weedon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit

Common questions in Weedon
Do you work for landlords with property near Aylesbury Vale Parkway station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Is Weedon within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
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.
Can you match the sealant to my frames?
Usually, yes. Tell us the frame colour when you get in touch and we’ll use the nearest match.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
What we’re called out for in Weedon
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Common reasons people contact us include:
- Mastic that has split away from the wall
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
If you look after a building such as Old School Room Chapel, the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep paint off silicone joints
- Keep timber frames painted
- Air rooms to keep condensation down around windows
- Keep solvents and bleach off the sealant
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
What window mastic looks like in Weedon
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Aylesbury Vale Parkway station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Old School Room Chapel include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
