Sand mastic in Staplefield, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We work on timber door frames, stone surrounds and brick reveals, and common reasons people get in touch are failed mastic on an exposed elevation and draughts and rain around sash boxes.
Somewhere as small as Staplefield, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months.

When it isn’t the sealant
In fairness, some problems need a different trade:
- Cracked or broken glass
- Timber that has rotted
- Whether work needs listed building consent

Staplefield questions
Do you cover Staplefield for sand mastic?
Yes. We work across London and the South East, and Staplefield is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Balcombe station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
How the visit works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. For a village or hamlet like Staplefield, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Staplefield homes and the weather
Historic houses like Tyes Place (about 0.4 miles east) are a reminder that the area around Staplefield 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Mark, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Balcombe station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as St Mark's CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Avoid patching sand mastic with silicone
- Ask the planning authority about consent for listed or conservation-area homes
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
What happens if it’s left?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Staplefield, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
