Sand mastic in Kingston Lisle, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you have draughts and rain around sash boxes and cracked mastic round a front door frame, we can put it right.
Around Kingston Lisle, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Questions from Kingston Lisle
Do you cover Kingston Lisle for sand mastic?
Yes. Our work covers London and the South East, and Kingston Lisle is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Is there a guarantee on sand mastic in Kingston Lisle?
All our work, in Kingston Lisle and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Why it’s worth doing now in Kingston Lisle
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Where a wall is exposed, as many are in small places like Kingston Lisle, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us and we’ll talk you through it.

Do you need sand mastic in Kingston Lisle?
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
People usually contact us after spotting one of these:
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
- Patchy fillers round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
In and around Kingston Lisle, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What sand mastic looks like in Kingston Lisle
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. With historic houses such as Ashdown House (about 4.7 miles south-west) nearby, there’s older building stock in the area around Kingston Lisle as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Check with your local planning authority if your home is listed
- Sort the mastic before the decorators arrive
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints from start to finish. For a village or hamlet like Kingston Lisle, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- 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 if parking is tricky
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules

DIY versus a professional finish
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 fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
