Ditton Hill questions
Is parking an issue for sand mastic in Ditton Hill?
Parking in Ditton Hill, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you cover Ditton Hill for sand mastic?
Yes, Ditton Hill is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we will advise.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
How we handle sand mastic in Ditton Hill
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you are dealing with cement or filler used on old window joints that has cracked and mastic dropping out of the joint, we can put it right.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Ditton Hill is something to talk through when you book.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Looking after it afterwards
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Leave the new mastic unpainted
- Go gently near the mastic when preparing windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Different surfaces, different methods
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.

Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to a full day, depending on how many windows.

Signs you need sand mastic in Ditton Hill
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
For site and facilities teams at buildings such as Long Ditton Infant and Nursery School, the mastic around its windows and doors needs looking after like any other building’s.

Frames and glazing around Ditton Hill
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Ditton Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
