Winnersh Window Mastic
Our applicators work in Winnersh on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps where the sill meets the wall
- Untidy mastic left by window fitters
- White mastic on grey or black frames
Keeping the joints in good condition
After the cure time, these simple habits help:
- Wipe condensation off the frames
- Avoid blasting the frames with a pressure washer
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Window mastic in Winnersh
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you’re dealing with hard, cracked sealant around windows and damp patches on the reveal after heavy rain, we can help, whatever the surface.
Around Winnersh, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
Our work is backed for twelve months.

Different surfaces, different methods
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Questions from Winnersh
Do you cover smaller places like Winnersh?
Yes, Winnersh is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Winnersh for window mastic?
Yes. Our work covers London and the South East, and Winnersh is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Work for landlords, hotels and businesses
For anyone letting property in or around Winnersh, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured.
Why deal with it now?
The work is quick compared with the damage it prevents: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In a smaller place like Winnersh, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Advice
Do you need window mastic in Winnersh?
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Look out for any of the following:
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
- Black, perished sealant on frames
- Draughts coming in around windows and doors
If you let a flat or house near Winnersh station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What else we do in Winnersh
Frames and glazing around Winnersh
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Mary the Virgin include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as The Forest School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
