Sand mastic in Stoke Lyne
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on tenement windows, timber door frames and sash and case windows, and common reasons people get in touch are gaps where the frame meets the masonry and old sand mastic that has cracked, crumbled or fallen out.
Homes in small places like Stoke Lyne 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.
Big or small, it’s backed by our 12-month guarantee in Stoke Lyne and across Oxfordshire.

Sand mastic in Stoke Lyne: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What else we do in Stoke Lyne
The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours per window, depending on the condition of the joints. In a small place like Stoke Lyne, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Decayed frames that need repair
- Cracked or broken glass
- Crumbling stone or brickwork round the window

Different surfaces, different methods
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Quotes for sand mastic in Stoke Lyne
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any mould that needs treating
- How many areas need sealing
- The number and length of the joints
- The old material and how stubborn it is
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Roughly how big the job is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Letting agents and landlords in Stoke Lyne can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Don’t run silicone over sand mastic
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
- Look over the window mastic once a year
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
