What the job involves on each surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.
Sand mastic in Puddledock
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. Typical jobs include gaps round a timber door in stone or brick and window mastic to renew ahead of painting, on period & listed homes, tenement windows and sash and case windows.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Puddledock as anywhere.
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.

- Open joints round the window box
- Draughty sash windows at the surround
- Tired mastic found when preparing windows for paint

Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a single window, longer for several. In a London area like Puddledock, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Puddledock homes and the weather
Historic houses like Chartwell (about 0.6 miles north-west) are a reminder that the area around Puddledock has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
For landlords with property near Edenbridge station, any sash windows need sound mastic to keep draughts and rain out. Homes close to Holy Trinity Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

How we quote for sand mastic
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Asking for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
Want a quote for sand mastic? Please ring 0345 464 0079 or send us an email and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Where we work in Puddledock
- Sash and case windows
- Timber door frames
- Stone surrounds
- Period & listed homes
- Brick reveals
- Tenement windows
Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
