Why it’s worth doing now in Lower Nazeing
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. In an older home around Lower Nazeing, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

Sand mastic in Lower Nazeing
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. If you have window mastic to renew ahead of painting and modern sealant on a period surround, we can put it right, whatever the surface.
In a smaller place like Lower Nazeing, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
What affects the cost of sand mastic
Jobs vary more than people expect. What affects the quote:

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

You don’t need to know the technical terms. Just tell us:
- Roughly how big the job is
- Any previous sealing or DIY work

Common questions in Lower Nazeing
Do you cover smaller places like Lower Nazeing?
Yes. Lower Nazeing is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Broxbourne station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, 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.
How long will you be here?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Bigger jobs take longer.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before we start.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant, and we will explain why.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
How it works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a single window, longer for several. Parking around Lower Nazeing is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.

Sand mastic in Lower Nazeing: 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.
Homes close to St Giles include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Broxbourne station, any sash windows need sound mastic to keep draughts and rain out.

Aftercare tips
Aftercare is simple:
- Go gently near the mastic when preparing windows
- Make sure water runs off the sill
- Keep modern sealant off the mastic
- Do not paint over the new mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
