Sand mastic in The Village
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we will explain which is best for yours. If you have window mastic to renew ahead of painting and patchy fillers round a sash window, we can put it right.
Homes in small places like The Village often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Can I do it myself?
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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like The Village, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- 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 finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on

Aftercare tips
Looking after new joints is easy:
- Go gently near the mastic when preparing windows
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
- Check the mastic when you check the paintwork
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
What affects the cost of sand mastic
The quote reflects the job in front of us. We look at:
- How easy the joints are to reach
- Which sealant suits the joint
- When we can work, for business premises
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
When you call or email, these details help:
- Whether it’s a home or a business

The Village homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as St Leonard's Hill (about 1.7 miles north) nearby, there’s older building stock in the area around The Village as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Windsor & Eton Central station, any sash windows need sound mastic to keep draughts and rain out. Historic houses such as St Leonard's Hill, about 1.7 miles north, show how far back building around The Village goes. Schools such as Windsor Girls' School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Questions from The Village
I let a flat near Windsor & Eton Central station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is The Village in your area for sand mastic?
Yes, The Village is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long does sand mastic take to go off?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint, then point it with sand mastic.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around The Village can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.
