Burmarsh Window Mastic
We cover Burmarsh for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
- Hard, cracked sealant around windows
Why deal with it now?
The work is quick compared with the damage it prevents: it takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Around Burmarsh, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Window mastic in Burmarsh
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before any work starts. To get one, phone 0345 464 0079 or email us with the number of frames and any access details for window mastic in Burmarsh. Typical jobs include gaps where the sill meets the wall and water coming in at the bottom corners of a door, on composite doors, uPVC windows and aluminium frames.
In a village or hamlet like Burmarsh, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Windows and doors in Burmarsh
Burmarsh is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
If you let a flat or house near Westenhanger station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we cannot put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- A sash or casement that won’t close properly
- Penetrating damp from a failed cavity tray or render
- Worn gaskets, brush seals or a door that has dropped
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take most of a day for a typical house, less for a few frames. In a small place like Burmarsh, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in

Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
When to call us in Burmarsh
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Common reasons people contact us include:
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the cost of window mastic
We quote each job individually. These are the things that affect it:
- Which sealant suits the joint
- Any mould that needs treating
- Whether the work is at height
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
You do not need to know the technical terms. Just tell us:
- If someone has resealed it before
- A few photos by email, if you can
- Any access issues, like height or stairs
- Where the property is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or send us an email.
Keeping the joints in good condition
So the new joints stay in good condition:
- Air rooms to keep condensation down around windows
- Repaint timber before it’s bare
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots are not blocked
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Questions from Burmarsh
Is Burmarsh within the area you cover?
Yes, Burmarsh is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is window mastic in a coastal place like Burmarsh any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
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 do one or both.
Is it OK to seal over old sealant?
No. The old sealant always comes out first.
Does the work come with a guarantee?
Yes. Every job comes with our one-year guarantee, and we’re fully insured.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
