Sand mastic in Scaynes Hill, 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 have mastic round period door frames that has failed and old cement repairs round a window that have failed, we can put it right, whatever the surface.
Around Scaynes Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Scaynes Hill and everywhere else we cover.

Signs you need sand mastic in Scaynes Hill
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
Any of these means the joints need attention:
- Crumbling sand mastic round a window
- Modern sealant on a period surround
- Open joints round the window box
- Cracked mastic round a front door frame
For landlords with property near Haywards Heath station, any sash windows need sound mastic to keep draughts and rain out.
What to look for in a quote

- Who does the work, and how experienced they are
Why it’s worth doing now in Scaynes Hill
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In a small place like Scaynes Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why us?
- A 12-month guarantee on all work
- 180+ five-star Google reviews
- Trusted Arbo and Everbuild sealants
- An ARBOMaster approved applicator

The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. In a small place like Scaynes Hill, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed

Sand mastic in Scaynes Hill: local notes
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. With historic houses such as Ockenden Manor (about 4.1 miles west) nearby, there’s older building stock in the area around Scaynes Hill as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like St Augustine's CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Augustine of Canterbury, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
Looking after new joints is easy:
- Take care around the mastic when scraping paint
- Renew mastic before redecorating the windows
- Clear gutters so water doesn’t pour onto the windows
- Check the mastic when you check the paintwork
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
