Drayton St Leonard Window Mastic
We cover Drayton St Leonard for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- A bead that does not match the frame
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
Why deal with it now?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a small place like Drayton St Leonard, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- You choose the colour before work begins
- 12-month guarantee on every job
- Approved under the ARBOMaster scheme
- Any old sealant cut out fully, not covered over
Window mastic for homes and businesses in Drayton St Leonard
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on aluminium frames, composite doors and window sills, and common reasons people get in touch are hard, cracked sealant around windows and gaps left after new windows were fitted.
Mastic can only go onto a dry, clean joint, so window work in Drayton St Leonard is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A one-year guarantee comes as standard.

Signs you need window mastic in Drayton St Leonard
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
Most people get in touch after spotting something like this:
- Draughty joints inside around the window
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
Rented homes near Culham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book
- Whether the sealant suits the joint
- How hidden problems are handled

Different surfaces, different methods
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as that’s a job for a joiner.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Common questions in Drayton St Leonard
Do you work for landlords with property near Culham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Drayton St Leonard?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we’re fully insured.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Will new mastic stop draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Leonard, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
