Sand mastic in Elmstead Market, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you’re dealing with weathered mastic on the most exposed windows and tired mastic found when preparing windows for paint, we can help, whatever the surface.
Around Elmstead Market, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Every job comes with a 12-month guarantee.

Windows and doors in Elmstead Market
Elmstead Market is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Castle House (about 4.8 miles north) are a reminder that the area around Elmstead Market 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’s traditional sand mastic.
For an older house near a landmark such as Church of St Anne and St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Alresford station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Elmstead Market questions
Do you cover smaller places like Elmstead Market?
Yes, Elmstead Market is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Elmstead Market any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
What guarantee comes with the work?
Our 12-month guarantee applies to all our work.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before work begins.
How much does sand mastic cost in Elmstead Market?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Common problems we fix in Elmstead Market
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they normally need raking out.
These are the problems we are asked about most:
- A silicone bead on a sash window that spoils the look
- Gaps between timber frames and stone or brick
- Cracked mastic round a front door frame
- Window mastic to renew ahead of painting
Managing a site like Elmstead Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
Comparing quotes

- How the surfaces are prepared before sealing

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
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.
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a single window, longer for several, depending on how much there is to do. For a job in Elmstead Market, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.

What else we do in Elmstead Market
What we cannot put right

- Whether work needs listed building consent

- Cracked or broken glass
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Brick reveals
- Stone surrounds
- Sash and case windows
- Timber door frames
- Period & listed homes
- Tenement windows
Different surfaces, different methods
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we will confirm what’s needed.
Aftercare tips
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
- Look over the window mastic once a year
- Take care around the mastic when scraping paint
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
