About our sand mastic in Tyler's Green
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on tenement windows, timber door frames and brick reveals, and common reasons people get in touch are crumbling sand mastic round a window and old cement repairs round a window that have failed.
Outdoor sealant needs dry, clean surfaces, so work on frames around Tyler's Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What we’re called out for in Tyler's Green
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
These are the problems we are asked about most:
- Weathered mastic on the most exposed windows
- Mastic that needs renewing before redecorating
- Open joints round the window box
- Cement or filler used on old window joints that has cracked
Managing a site like Godstone Village School? Then the mastic around its windows and doors needs looking after like any other building’s.

Why act early in Tyler's Green
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like Tyler's Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Tyler's Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

What affects the cost of sand mastic
There’s no set price list, because no two jobs are the same. What we look at:

- The number of rooms or windows
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Windows and doors in Tyler's Green
With historic houses such as Titsey Place (about 3.9 miles north-east) nearby, there’s older building stock in the area around Tyler's Green 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

If you live in an older home near Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
