About our window mastic in Bullsmoor
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on composite doors, uPVC windows and timber windows & doors, and common reasons people get in touch are damp patches on the reveal after heavy rain and draughty joints inside around the window.
Homes around Bullsmoor range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Whatever the size of the job, it’s backed by our one-year guarantee.

What window mastic looks like in Bullsmoor
Historic houses like Forty Hall (about 1 mile south-west) are a reminder that the area around Bullsmoor 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. 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.
For landlords with property near Turkey Street station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Honilands Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Do you need window mastic in Bullsmoor?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
For an older house near a landmark such as St George's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

How the job changes by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
How the visit works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames in most cases. A visit to Bullsmoor is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

What happens if it’s left?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In a smaller place like Bullsmoor, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.
