Sand mastic for sash & case windows in Friday Street, Surrey
Window and door surrounds in Friday Street need attention? We cut out the old, prepare the joints and apply the right sealant.
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Draughty sash windows at the surround
What we cannot put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Planning or listed building consent (your local planning authority decides)
- Putty and glazing repairs
- Sashes that rattle, stick or won’t open
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

Sand mastic in Friday Street
Across Friday Street, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on brick reveals, stone surrounds and tenement windows, and the jobs we see most are mastic dropping out of the joint and gaps between timber frames and stone or brick.
In a village or hamlet like Friday Street, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, in Friday Street and everywhere else we cover.

How the visit works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints in most cases. Somewhere like Friday 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.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises

Related advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Windows and doors in Friday Street
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Polesden Lacey (about 4.2 miles north) nearby, there’s older building stock in the area around Friday Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Belmont Prep School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Friday Street questions
Is Friday Street within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Gomshall station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Where a wall is exposed, as many are in small places like Friday Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
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.
