Sand mastic in Enton Green, done properly
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We work on tenement windows, period & listed homes and timber door frames, and common reasons people get in touch are gaps between timber frames and stone or brick and crumbling sand mastic round a window.
Mastic can only go onto a dry, clean joint, so window work in Enton Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows. In a small place like Enton Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- 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.
Preparing for the visit

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
We also work for property managers and facilities teams. Several sites can be quoted together.
Different surfaces, different methods
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Common questions in Enton Green
Will you come out to Enton Green?
Yes, Enton Green is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Milford (Surrey) station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

Signs you need sand mastic in Enton Green
Timber frames move with the seasons. The movement cracks the mastic over time.
If you can see any of these, it’s time to have the joints looked at:
- Cracked mastic round a front door frame
- Silicone on a period window that looks wrong
- Wind and rain getting in round a sash window
- Failed mastic on an exposed elevation
Schools such as The Chandler CofE Aided Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Which colour the sealant will be
- What insurance they hold
- What guarantee comes with the work
- Who turns up on the day
How to look after the new joints
Aftercare is simple:
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What sand mastic looks like in Enton Green
With historic houses such as Loseley Park (about 4.1 miles north) nearby, there’s older building stock in the area around Enton 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Milford (Surrey) station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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.
