How we handle sand mastic in Peaslake
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on timber door frames, stone surrounds and tenement windows, and common reasons people get in touch are tired mastic found when preparing windows for paint and crumbling sand mastic round a window.
Somewhere as small as Peaslake, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Common questions in Peaslake
Do you cover Peaslake for sand mastic?
Yes. We work across London and the South East, and Peaslake is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Do you work for landlords with property near Gomshall station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
How long does sand mastic take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including the preparation. We will confirm how long when we quote.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will advise.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the job changes by surface
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
Common problems we fix in Peaslake
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Look out for these signs:
- Draughts and rain around sash boxes
- Gaps round a timber door in stone or brick
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
Letting a property close to Gomshall station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a single window, longer for several. Somewhere like Peaslake needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

What affects the quote in Peaslake
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The amount of work
- The type of sealant required
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What we need to know
To help us quote quickly, let us know:
- How we’d reach the joints
- The type of property
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Windows and doors in Peaslake
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Chilworth Manor (about 4.2 miles north-west) nearby, there’s older building stock in the area around Peaslake as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to Church of St Mark include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Peaslake, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
