Window mastic in Elsted Marsh
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on window sills, composite doors and aluminium frames, and common reasons people get in touch are cracked or shrunken mastic around the frame and sealant in the wrong colour for the frame.
Around Elsted Marsh, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Elsted Marsh needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Frames and glazing around Elsted Marsh
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Cowdray House (about 3.5 miles east) are a reminder that the area around Elsted Marsh 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.
In and around Elsted Marsh, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

What happens if it’s left?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Elsted Marsh, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Keeping the joints in good condition
Aftercare is simple:
- Wash the frames with mild soapy water
- Look round the frames every year or so
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
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. Any of these is worth a call.
How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- Working hours on commercial sites
- Whether the work is at height
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Do you need window mastic in Elsted Marsh?
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Mastic that’s falling out in pieces
- Draughty joints inside around the window
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
If you live in an older home near St George's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Whether VAT is included
- What product goes in the joint
- What insurance they hold
