Epwell Sand Mastic
Our applicators work in Epwell on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- A silicone bead on a sash window that spoils the look
- Mastic dropping out of the joint
- Open joints round the window box
Sand mastic for homes and businesses in Epwell
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. If you have mastic dropping out of the joint and a silicone bead on a sash window that spoils the look, we can help, whatever the surface.
Somewhere as small as Epwell, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Windows and doors in Epwell
London and the South East are among 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 Upton House (about 3.3 miles north) are a reminder that the area around Epwell has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St Anne, the joint between an old wall and a newer frame is generally the first place rain gets in.

What affects the quote in Epwell
Call for a quick quote. The main things that affect it are:
- The product the joint needs
- Any mould that needs treating
- How many rooms, windows or areas are involved
- When we can work, for business premises
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
Asking for a quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- The rough size of the job
- Whether it has been sealed before

We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details.
What we are called out for in Epwell
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Window mastic to renew ahead of painting
- Crumbling sand mastic round a window
Around Epwell, as everywhere, sand mastic is only as good as the preparation behind it.
Questions to ask before you book
- How much experience the applicator has
- What happens if the job turns out different
- Is the old sealant removed completely?
- Which colour the sealant will be
Questions from Epwell
Is Epwell in your area for sand mastic?
Yes. We work across London and the South East, and Epwell is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is there a guarantee on sand mastic in Epwell?
All our work, in Epwell and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before we start.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
How the job changes by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
