Sand Mastic in Sandway
Our applicators work in Sandway on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Failed mastic on an exposed elevation
- Gaps between timber frames and stone or brick
- Draughts and rain around sash boxes
Different surfaces, different methods
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Timber door frames
Round a period front door, sand mastic gives the right look.
Sand mastic in Sandway, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. If you’re dealing with draughty sash windows at the surround and a silicone bead on a sash window that spoils the look, we can put it right, on timber door frames, brick reveals and sash and case windows alike.
Homes in small places like Sandway 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.
Your job is guaranteed for a year, as with all our work.

How the visit works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a single window, longer for several from start to finish. For a village or hamlet like Sandway, 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.
- 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
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
FAQs for Sandway
Do you cover smaller places like Sandway?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Sandway in your area for sand mastic?
Yes. We work across London and the South East, and Sandway is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around Sandway can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What affects the quote in Sandway
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
Photos help, but a description is a good start. Please mention:
- The type of property
- Where the job is, and your postcode
- The rough size of the job

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work.
What we’re called out for in Sandway
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Common reasons people contact us are:
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
If you live in an older home near St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic in Sandway: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Leeds Castle (about 3.3 miles north-west) are a reminder that the area around Sandway has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Lenham station? Then any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Platts Heath Primary School, its window and door frames need their mastic kept sound, just like a home’s.
