Sand mastic for homes and businesses in Little Laver
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on sash and case windows, timber door frames and period & listed homes, and the jobs we see most are wind and rain getting in round a sash window and window mastic to renew ahead of painting.
Outdoor sealant needs dry, clean surfaces, so work on frames around Little Laver is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common questions in Little Laver
What guarantee comes with sand mastic in Little Laver?
All our work, in Little Laver and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is Little Laver within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll advise.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several, and the area is left clean. Somewhere as small as Little Laver, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
How to get a quote

Related advice
Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Little Laver can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Why choose Mr Mastic in Little Laver
- ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over
- Experience in homes, commercial sites and hotels
- A 12-month guarantee on all work
Take a look at our cost guide or what customers say.
Do you need sand mastic in Little Laver?
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
The problems people generally mention when they call are:
- Open joints round the window box
- Mastic dropping out of the joint
- Modern sealant on a period surround
- Mastic that needs renewing before redecorating
In the older streets around Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before you book anyone
- What product goes in the joint
- What the cure time is
- Whether all the old sealant comes out first
- How the surfaces are prepared before sealing
Aftercare tips
After the cure time, these simple habits help:
- Avoid patching sand mastic with silicone
- Don’t paint over the new mastic
- Clear gutters so water does not pour onto the windows
- Find out about consent before window work on a listed home
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Honest limits
Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:
- Whether work needs listed building consent
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
