How we handle sand mastic in Stoke
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. If you have gaps round a timber door in stone or brick and cement or filler used on old window joints that has cracked, we can help, on period & listed homes, tenement windows and timber door frames alike.
In a village or hamlet like Stoke, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Signs you need sand mastic in Stoke
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Signs it’s time to call us include:
- Mastic worn away on windows facing the weather
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
Schools such as Stoke Primary Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

- What happens if the job turns out different
- Who does the work, and how experienced they are

Questions from Stoke
Do you cover Stoke for sand mastic?
Yes, Stoke is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is sand mastic in a coastal place like Stoke any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll talk you through it.
How long does the job take?
Most jobs take a few hours for a single window, longer for several. Your quote will say how long we expect yours to take.
Should I use sand mastic or silicone?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Why act early in Stoke
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. 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.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
What you get with us
- Anti-fungal silicone where joints get wet
- We are fully insured
- A 12-month guarantee on all work
- Neat joints and a tidy finish
The process
At the end, we look at the finished work together. The visit itself normally takes a few hours for a single window, longer for several, depending on the amount of work. In a small place like Stoke, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Before we arrive
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in

Stoke homes and the weather
Stoke is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Peter and St Paul include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Landmarks near Stoke

Aftercare tips
A little care helps the new joints last. We recommend:
- Get any rot dealt with first
- Leave the new mastic unpainted
- Avoid heavy scraping on the mastic joint
- Look over the window mastic once a year
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
