Window & door mastic in East Burnham, Slough
Window and door frames in East Burnham need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

About our window mastic in East Burnham
Around East Burnham we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you’re dealing with black, perished sealant on frames and cracked sealant at the sill ends, we can put it right, whatever the surface.
Homes in small places like East Burnham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Window mastic in East Burnham: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Cliveden (about 2.8 miles west) are a reminder that the area around East Burnham has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near St John the Evangelist, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Caldicott School, the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep timber frames painted
- Clear any debris from frame drain holes
- Wash the frames with mild soapy water
- Avoid harsh chemicals near the mastic
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

When to call us in East Burnham
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.
The problems people usually mention when they call are:
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
If you let a flat or house near Burnham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Why act early in East Burnham
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Older cottages and farmhouses around East Burnham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
