About our sand mastic in Bocking's Elm
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you have patchy fillers round a sash window and mastic that needs renewing before redecorating, we can put it right, whatever the surface.
Many houses in smaller places like Bocking's Elm have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Don’t run silicone over sand mastic
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
- Ask a joiner to look at soft timber first
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
Sand mastic in Bocking's Elm: local notes
Bocking's Elm is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Thorpe Hall (about 3.8 miles north-east) are a reminder that the area around Bocking's Elm 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.
For landlords with property near Clacton-On-Sea station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as St Clare's Catholic Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Landlord and commercial work in Bocking's Elm
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In an older home around Bocking's Elm, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

A typical job takes a few hours per window, depending on the condition of the joints, including the preparation. Your quote will say how long we expect yours to take.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
