About our window mastic in Church Hanborough
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you’re dealing with hard, cracked sealant around windows and mastic that’s falling out in pieces, we can help, whatever the surface.
Around Church Hanborough, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

What the job involves on each surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Surfaces we seal

Why act early in Church Hanborough
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a small place like Church Hanborough, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Common problems we fix in Church Hanborough
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
These are the problems we’re asked about most:
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
- Gaps left after new windows were fitted
For landlords with property near Hanborough station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Frames and glazing around Church Hanborough
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Blenheim Palace (about 2 miles north-east) are a reminder that the area around Church Hanborough has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Hanborough Manor CofE School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How much does window mastic cost in Church Hanborough?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you guarantee window mastic?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Is the new sealant paintable?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
