About our sand mastic in Stoke
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We’re often asked to deal with silicone on a period window that looks wrong and cement or filler used on old window joints that has cracked, across stone surrounds, brick reveals and timber door frames.
Around Stoke, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, it’s backed by our one-year guarantee in Stoke and across Hampshire.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
When it isn’t the sealant
It helps to know what we cannot do too:
- Putty and glazing repairs
- Decisions on consent for listed homes
- Timber that has rotted
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. In a small place like Stoke, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Tell us about any water getting in
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

What we are called out for in Stoke
Water gets into small cracks in the mastic and pushes it out. Exposed elevations usually fail first.
Keep an eye out for these signs:
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
- Failed mastic on an exposed elevation
Rented homes near Whitchurch (Hampshire) station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- What product goes in the joint
- Who turns up on the day
- Whether all the old sealant comes out first
- Whether they’re fully insured
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Avoid heavy scraping on the mastic joint
- Clear gutters so water does not pour onto the windows
- Keep modern sealant off the mastic
- Ask the planning authority about consent for listed or conservation-area homes
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Why it’s worth doing now in Stoke
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. In a small place like Stoke, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Stoke homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as St Mary Bourne Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
