Why deal with it now?
Gaps round a sash window let in rain and draughts. 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 Westenhanger, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Why book with us
- Homes, businesses and hotels
- We are fully insured
- An ARBOMaster approved applicator

About our sand mastic in Westenhanger
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We’re often asked to deal with silicone on a period window that looks wrong and old cement repairs round a window that have failed, on brick reveals, timber door frames and sash and case windows.
Homes in small places like Westenhanger often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee in Westenhanger and across Kent.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- Sort the mastic before the decorators arrive
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

What we’re called out for in Westenhanger
Shallow joints are a common cause. 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’re asked about most:
- Gaps where the frame meets the masonry
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
- Old cement repairs round a window that have failed
If you let a flat or house near Westenhanger station, older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- What insurance they hold
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
- How long the guarantee is
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several. Somewhere like Westenhanger needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear the area around the work
- Let us know about stairs, lifts or work at height

Advice
Sand mastic in Westenhanger: local notes
Westenhanger is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to All Saints Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Lympne Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
