About our sand mastic in Loughton
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on period & listed homes, stone surrounds and timber door frames, and the jobs we see most are draughty sash windows at the surround and gaps between timber frames and stone or brick.
Around Loughton, many houses have gained conservatories, French doors or replacement windows over time. Each one adds more joints to look after, and those joints age at different rates. Sills, frame heads and glazing joints are where leaks normally start.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. A visit in Loughton needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive

Advice
Frames and glazing around Loughton
Historic houses like Hill Hall (about 4.1 miles north-east) are a reminder that the area around Loughton has older buildings as well as new. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St. John's Church, 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 Chingford station, any sash windows need sound mastic to keep draughts and rain out.

What we’re called out for in Loughton
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
If you can see any of these, it’s time to have the joints looked at:
- Window mastic to renew ahead of painting
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
Managing a site like The Alderton Infant School? Then the mastic around its windows and doors needs looking after like any other building’s.

Questions from Loughton
Can you help a landlord with a rental near Chingford station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
What guarantee comes with sand mastic in Loughton?
All our work, in Loughton and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Are you fully insured?
Yes, we’re fully insured for every job we do.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes and newer frames suit modern sealant.
What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Black mould and gaps in sealant don’t fix themselves, and in a busy home in Loughton they get worse with every use. Now is the easy time to put it right.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What affects the cost of sand mastic
We quote each job individually. These are the things that affect it:
- Working hours on commercial sites
- Whether the work is at height
- How many rooms, windows or areas are involved
- The size of the job
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
To help us quote quickly, let us know:
- If someone has resealed it before
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Roughly how big the job is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
