Sand mastic in Lower Farringdon, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. Typical jobs include patchy fillers round a sash window and draughty sash windows at the surround, on sash and case windows, timber door frames and brick reveals.
Homes in small places like Lower Farringdon often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, large or small.

What happens if it’s left?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Where a wall is exposed, as many are in small places like Lower Farringdon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before we start.

Timber door frames
Round a period front door, sand mastic gives the right look.
Do you need sand mastic in Lower Farringdon?
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
If you can see any of these, it’s time to have the joints looked at:
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
- Gaps where the frame meets the masonry
If you let a flat or house near Alton station, any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before booking
- Which sealant they’ll use, and why

Common questions in Lower Farringdon
Do you cover Lower Farringdon for sand mastic?
Yes, Lower Farringdon is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Do you cover smaller places like Lower Farringdon?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They’ll tell you if consent is needed.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee, and we’re fully insured.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What sand mastic looks like in Lower Farringdon
With historic houses such as Bentworth Hall (about 3.5 miles north-west) nearby, there’s older building stock in the area around Lower Farringdon as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a single window, longer for several, depending on the size of the job.

- First we agree which joints need doing.
- We remove the old, loose mastic.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Move anything stored near the joints

Related advice
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
