Why deal with it now?
Replacing sash windows is a big decision for a period home 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. Older cottages and farmhouses around Shortgate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

Different surfaces, different methods
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Windows and doors in Shortgate
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Glyndebourne (about 3.5 miles south-west) are a reminder that the area around Shortgate has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Is it possible to paint over sand mastic?

Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
What guarantee comes with the work?
You get our one-year guarantee to all our work.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How long does sand mastic take?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several, and the area is left clean. In a small place like Shortgate, access is normally 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.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Advice
What we’re called out for in Shortgate
Shallow joints are a common cause. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
Look out for these signs:
- Gaps where the frame meets the masonry
- A silicone bead on a sash window that spoils the look
- Cracked mastic round a front door frame
- Failed mastic on an exposed elevation
Glyndebourne, about 3.5 miles south-west, is one of the historic houses in the wider area around Shortgate, and older homes nearby need a sealant that suits their walls.
Questions to ask before booking
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- What guarantee comes with the work
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Sashes that rattle, stick or will not open
- Decayed frames that need repair
- Decisions on consent for listed homes
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
