Sand mastic in Addlestone, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes, across brick reveals, sash and case windows and tenement windows.
Houses in smaller places like Addlestone can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Frames and glazing around Addlestone
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Botleys Mansion (about 1.8 miles west) nearby, there’s older building stock in the area around Addlestone as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Darley Dene Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Addlestone station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near St Paul's, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the job changes by surface
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Crumbling stone or brickwork round the window
- Cracked or broken glass
- Whether work needs listed building consent
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Timber door frames
- Tenement windows
- Sash and case windows
- Stone surrounds
- Period & listed homes
- Brick reveals
Why act early in Addlestone
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Homes in smaller places like Addlestone can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How it works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. For a job in Addlestone, 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 check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
