Sand mastic in Abbey Wood
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. If you’re dealing with silicone on a period window that looks wrong and window mastic to renew ahead of painting, we can help.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Abbey Wood.
All our work is covered by a 12-month guarantee.

Leave it or put it right?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a flat in Abbey Wood, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Clear gutters so water doesn’t pour onto the windows
- Inspect the joints round the windows every year or so
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Signs you need sand mastic in Abbey Wood
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Look out for these signs:
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
For landlords with property near Abbey Wood station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. In Abbey Wood, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on

Sand mastic in Abbey Wood: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
In the older streets around Saint Michael and All Angels, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Abbey Wood is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, 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.
