How we handle sand mastic in Rooksdown
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on sash and case windows, stone surrounds and period & listed homes, and common reasons people get in touch are gaps where the frame meets the masonry and gaps round a timber door in stone or brick.
In a smaller place like Rooksdown, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Common problems we fix in Rooksdown
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Signs it’s time to call us include:
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- Mastic that needs renewing before redecorating

Looking after it afterwards
To keep the joints looking good and working properly:
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
- Have rotten timber repaired before new mastic goes in
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Putty and glazing repairs
- Decisions on consent for listed homes
- Damaged stone surrounds
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

Frames and glazing around Rooksdown
Historic houses like The Vyne (about 2.2 miles north-east) are a reminder that the area around Rooksdown has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
The Vyne, about 2.2 miles north-east, is one of the historic houses in the wider area around Rooksdown, and older homes nearby need a sealant that suits their walls. Schools such as Fort Hill Community School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How it works

- 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.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
