About our sand mastic in Sutton
We work across Sutton renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on period & listed homes, sash and case windows and timber door frames, and people most often call us about tired mastic found when preparing windows for paint and old cement repairs round a window that have failed.
Mastic can only go onto a dry, clean joint, so window work in Sutton is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Questions from Sutton
Do you cover smaller places like Sutton?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Sutton affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
How long does sand mastic take to go off?
Not straight away. The skin forms first, and the full set comes later and we will give you an idea for your job.
How do I get a quote for sand mastic in Sutton?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a single window, longer for several. In a small place like Sutton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

Advice
Other services in Sutton
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
For landlords and businesses
Landlords and letting agents in Sutton can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
- Look over the window mastic once a year
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
Common problems we fix in Sutton
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
These are the problems we are asked about most:
- Draughty sash windows at the surround
- Mastic round period door frames that has failed
- Modern sealant on a period surround
- Crumbling sand mastic round a window
For landlords with property near Southend Airport station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before booking
- Are they insured?
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
- How the colour is chosen
Different surfaces, different methods
Timber door frames
Round a period front door, sand mastic gives the right look.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Sand mastic in Sutton: local notes
Sutton is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
In the older streets around Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Stambridge Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Sutton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.
