Coxhill Green Sand Mastic
Problem with your window and door surrounds in Coxhill Green? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
- A silicone bead on a sash window that spoils the look
Sand mastic in Coxhill Green, done properly
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you are dealing with old cement repairs round a window that have failed and gaps round a timber door in stone or brick, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Coxhill Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job comes with our 12-month guarantee, wherever you are in Surrey.

How it works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for a single window, longer for several. For a village or hamlet like Coxhill Green, the journey is planned in advance: 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 check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

Questions from Coxhill Green
Do you cover smaller places like Coxhill Green?
Yes. Coxhill Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Longcross station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames normally get a flexible sealant.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

How the job changes by surface
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Stone surrounds
The stone is treated with care while raking out the old mastic.
DIY versus a professional finish
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Coxhill Green homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Botleys Mansion (about 3.5 miles north-east) are a reminder that the area around Coxhill Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as St Lawrence CofE (Aided) Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Lawrence include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Do you need sand mastic in Coxhill Green?
Timber frames move with the seasons. That movement opens up the mastic joint over time.
The most common problems we see are:
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
- Modern sealant on a period surround
- Mastic dropping out of the joint
If you let a flat or house near Longcross station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Leave it or put it right?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Coxhill Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before work begins.
