Why it’s worth doing now in Smeeth
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In a small place like Smeeth, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Why us?
- Quality sealants from Arbo and Everbuild
- Tidy, careful work
- Approved under the ARBOMaster scheme
- A 12-month guarantee on all work

What else we do in Smeeth
Windows and doors in Smeeth
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Westenhanger Castle (about 3.4 miles south-east) are a reminder that the area around Smeeth has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Westenhanger station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Decisions on consent for listed homes
- Putty and glazing repairs
- Timber that has rotted
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on
- Period & listed homes
- Brick reveals
- Sash and case windows
- Tenement windows
- Timber door frames
- Stone surrounds
Common problems we fix in Smeeth
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they usually need raking out.
Any of these means the joints need attention:
- Old cement repairs round a window that have failed
- Weathered mastic on the most exposed windows
- Window mastic to renew ahead of painting
- Old sand mastic that has cracked, crumbled or fallen out
For site and facilities teams at buildings such as Smeeth Community Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a single window, longer for several from start to finish.

- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
