About our sand mastic in Abbotswood
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on sash and case windows, tenement windows and stone surrounds, and the jobs we see most are open joints round the window box and cement or filler used on old window joints that has cracked.
Homes around Abbotswood range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Find out about consent before window work on a listed home
- Ask a joiner to look at soft timber first
- Look over the window mastic once a year
- Leave the new mastic unpainted
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It normally takes anything from a few hours to a full day, depending on how many windows. For a job in Abbotswood, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- 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
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In an older home around Abbotswood, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Frames and glazing around Abbotswood
London and the South East are among the drier parts 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 Guildford Castle (about 0.7 miles south-west) nearby, there’s older building stock in the area around Abbotswood as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near London Road (Guildford) station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Lanesborough School, its window and door frames need their mastic kept sound, just like a home’s.
