Sand mastic for homes and businesses in Gordon Hill
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you have open joints round the window box and wind and rain getting in round a sash window, we can put it right, whatever the surface.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking, and access in Gordon Hill is something to talk through when you book.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions

When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Sashes that need overhauling
- Putty and glazing repairs
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
What we seal
- Stone surrounds
- Period & listed homes
- Sash and case windows
- Timber door frames
- Tenement windows
- Brick reveals
Why deal with it now?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Gordon Hill.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Windows and doors in Gordon Hill
With historic houses such as Forty Hall (about 0.9 miles north-east) nearby, there’s older building stock in the area around Gordon Hill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
If you live in an older home near St Michael & All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Gordon Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

DIY sealant or a professional job?
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 fails, we can still redo it.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Common problems we fix in Gordon Hill
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
People usually contact us after spotting one of these:
- Mastic worn away on windows facing the weather
- Cement or filler used on old window joints that has cracked
- Draughty sash windows at the surround
- Open joints round the window box
Schools such as St Michael's CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
