Your questions about sand mastic in Wapping
Is parking a problem for a job in Wapping?
Parking in Wapping, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Wapping station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover Wapping?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we’ll advise.
Can you replace silicone on a period window with sand mastic?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Sand mastic in Wapping, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on period & listed homes, tenement windows and stone surrounds, and people most often call us about draughts and rain around sash boxes and gaps between timber frames and stone or brick.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Common problems we fix in Wapping
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Most people get in touch after spotting one of these:
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
- Draughts and rain around sash boxes
- Gaps where the frame meets the masonry
Homes close to St Peter's include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Is VAT in the price?
- How the colour is chosen
- What insurance they hold
- Whether the sealant suits the joint
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Putty and glazing repairs
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

- We remove the old, loose mastic.
- We pack any deep voids first.

Advice
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Combining jobs into one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

Wapping homes and the weather
With historic houses such as Mansion House (about 1.3 miles west) nearby, there’s older building stock in the area around Wapping as well as newer homes. 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 it’s worth checking before booking.
Letting a property close to Wapping station? Then any sash windows need sound mastic to keep draughts and rain out. Wapping is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
