Window mastic in Seale
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. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you’re dealing with hard, cracked sealant around windows and untidy mastic left by window fitters, we can help, whatever the surface.
Around Seale, 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.
All our work is covered by a 12-month guarantee, wherever you are in Surrey.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Questions from Seale
Will you come out to Seale?

Do you cover Seale for window mastic?
Yes, Seale is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Is the new sealant paintable?
Not normally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.
When to call us in Seale
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Signs it’s time to call us include:
- Cracked or shrunken mastic around the frame
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
If you live in an older home near Church of St Laurence, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- Who turns up on the day
- Is VAT in the price?
- What preparation is included
- How the colour is chosen
What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a morning for a couple of windows and a door. Somewhere like Seale needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
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 they get particular care.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Check the mastic once a year
- Keep paint and stain on wooden frames in good order
- Keep paint off silicone joints
- Ventilate rooms so frames do not stay wet inside
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Frames and glazing around Seale
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. Historic houses like Wanborough Manor (about 2.4 miles east) are a reminder that the area around Seale 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 is traditional sand mastic.
If you look after a building such as St Paul's CofE Infant School & Nursery, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Ash station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
