How we handle sand mastic in Brewer Street
Across Brewer Street, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on brick reveals, stone surrounds and timber door frames, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and cement or filler used on old window joints that has cracked.
Around Brewer Street, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, you get the same one-year guarantee in Brewer Street and across Surrey.

How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. Somewhere like Brewer Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive

- Mention any sign-in or site rules at work premises

Advice
Sand mastic in Brewer Street: local notes
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.
Managing a site like Bletchingley Village Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Merstham station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

What we are called out for in Brewer Street
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
People usually contact us when they notice one of these:
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
- Silicone on a period window that looks wrong
Homes close to Church of St Mary the Virgin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

- Whether all the old sealant comes out first
Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Brewer Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
How long does sand mastic take?
That depends on how much there is to do, but as a guide it takes a few hours for a single window, longer for several. We will tell you when we quote.
What information do you need?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Find out about consent before window work on a listed home
- Inspect the joints round the windows every year or so
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
