Stroude Window Mastic
Our applicators work in Stroude on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
Window mastic in Stroude
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Typical jobs include mastic that has split away from the wall and cracked internal joints between frame and plaster, across uPVC windows, window sills and composite doors.
In a village or hamlet like Stroude, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, you get the same one-year guarantee.

Common questions in Stroude
Do you cover Stroude for window mastic?
Yes. Our work covers London and the South East, and Stroude is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Stroude?
Yes, Stroude is covered. 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.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
What information do you need?
Let us know what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Are you fully insured?
Yes. Full insurance covers our work.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Stroude.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Older cottages and farmhouses around Stroude can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

What we are called out for in Stroude
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
The most common problems we see are:
- Cracked sealant at the sill ends
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
In the older streets around Christ Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- Is VAT in the price?
- Whether all the old sealant comes out first
- How long the guarantee is
- How hidden problems are handled
How to look after the new joints
So the new joints stay in good condition:
- Keep drainage slots and sill grooves clear
- Ventilate rooms so frames don’t stay wet inside
- Avoid blasting the frames with a pressure washer
- Keep paint off silicone joints
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.

Windows and doors in Stroude
Historic houses like Botleys Mansion (about 2.7 miles south) are a reminder that the area around Stroude has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as St Ann's Heath Junior School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Virginia Water station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
