The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. In a small place like Afton Park, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Move anything stored near the joints

Advice
How we handle sand mastic in Afton Park
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you are dealing with open joints round the window box and mastic round period door frames that has failed, we can put it right, on brick reveals, period & listed homes and tenement windows alike.
Homes in small places like Afton Park 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.
A 12-month guarantee comes as standard.

Your questions about sand mastic in Afton Park
Do you cover Afton Park for sand mastic?
Yes. Our work covers London and the South East, and Afton Park is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Afton Park?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you fully insured?
Yes. We are fully insured for every job we do.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
What affects the cost of sand mastic
We do not publish a price list. The quote depends on:
- How easy the joints are to reach
- The old material and how stubborn it is
- The size of the job
- Mould in or behind the old joints
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Asking for a quote
To make quoting easier, let us know:
- How we’d reach the joints
- The rough size of the job
- What’s wrong with the joints now
- A few photos by email, if you can
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll take it from there.
Can I do it myself?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Different surfaces, different methods
Period and listed homes
A traditional finish suits a period property.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
Signs you need sand mastic in Afton Park
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they normally need raking out.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Open joints round the window box
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
Homes close to St. Agnes' Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What to look for in a quote
- What insurance they hold
- How much experience the applicator has
- Is the old sealant removed completely?
- How long to leave it before use
When it isn’t the sealant
In fairness, some problems need a different trade:
- Decisions on consent for listed homes
- Crumbling stone or brickwork round the window
- Sashes that rattle, stick or won’t open
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.

Afton Park homes and the weather
Afton Park 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. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like All Saints Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
