Frames and glazing around Anmore
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.
Schools such as Denmead Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How we handle window mastic in Anmore
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on timber windows & doors, patio & French doors and aluminium frames, and common reasons people get in touch are draughty joints inside around the window and untidy mastic left by window fitters.
Somewhere as small as Anmore, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months.

When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
- Rotten timber, which needs a joiner first
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
What we seal
- Window sills
- Aluminium frames
- Composite doors
- uPVC windows
- Patio & French doors
- Timber windows & doors
Surface by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Landlords, agents and businesses in Anmore
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Do you need window mastic in Anmore?
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Keep an eye out for any of the following:
- A bead that does not match the frame
- Mastic that has split away from the wall
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
Letting a property close to Bedhampton station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

What happens if it’s left?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Around Anmore, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Why us?
- A sealant colour to suit the surroundings
- Anti-fungal sanitary silicone in wet areas
- Over 20 years’ experience

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Anmore, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- 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.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
