Little Sandhurst homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as New Scotland Hill Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Michael, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our sand mastic in Little Sandhurst
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. Typical jobs include mastic round period door frames that has failed and mastic worn away on windows facing the weather, on brick reveals, sash and case windows and tenement windows.
Houses in smaller places like Little Sandhurst can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
All our work comes with our one-year guarantee.

Questions from Little Sandhurst
Is Little Sandhurst within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Sandhurst station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What should I tell you?
Let us know what needs doing and where, plus pictures if you have them. If we need more, we’ll ask.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
Do you need sand mastic in Little Sandhurst?
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
It’s worth asking for a quote if you see:
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Patchy fillers round a sash window
- Cracked mastic round a front door frame
Rented homes near Sandhurst station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What else we do in Little Sandhurst
Why deal with it now?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a smaller place like Little Sandhurst, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Sashes that rattle, stick or will not open
- Putty and glazing repairs
- Timber that has rotted
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

How it works
We keep the work tidy and contained to the joints we are treating. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. A visit to Little Sandhurst is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
