Leave it or put it right?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Older cottages and farmhouses around Littleton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Sand mastic for homes and businesses in Littleton
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. We work on timber door frames, period & listed homes and brick reveals, and common reasons people get in touch are draughts and rain around sash boxes and patchy fillers round a sash window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Littleton is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, whatever its size.

What we are called out for in Littleton
Rain on the window surround works into any crack and loosens it further. Exposed elevations generally fail first.
Look out for these signs:
- Draughty sash windows at the surround
- Gaps where the frame meets the masonry
- Window mastic to renew ahead of painting
- Mastic dropping out of the joint
If you live in an older home near Church of St Catherine, the joint between an old wall and a newer frame is normally the first place rain gets in.

Sand mastic in Littleton: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Harestock Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Winchester station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Can I do it myself?
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Questions from Littleton
Is Littleton in your area for sand mastic?
Yes. Our work covers London and the South East, and Littleton is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Will you come out to Littleton?
Yes, Littleton is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you guarantee sand mastic work?
You get our 12-month guarantee to all our work.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Is consent needed for window work on a listed home?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Littleton, 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 the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- 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.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
