External mastic in Thaxted
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. If you are dealing with moss and dirt in joints with no sealant left and sealant that has lost its bond to the brick or render, we can put it right, whatever the surface.
In a smaller place like Thaxted, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
You get a 12-month guarantee, the same in Thaxted as everywhere else we work.

What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Thaxted questions
Do you cover smaller places like Thaxted?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Thaxted for external mastic?
Yes. Our work covers London and the South East, and Thaxted is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Are you insured?
Yes, we are fully insured for every job we do.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it does not stand out.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
What affects the quote in Thaxted
We quote each job individually. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- Working hours on commercial sites
- Mould in or behind the old joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- Where the job is, and your postcode
- Whether it has been sealed before
- The type of property
If you’re in Thaxted and need external mastic, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we will agree the price before any work begins.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Check the sealant is paintable before painting near it
- Check external joints each spring
- Act on the first splits you see
- Clear growth from the base of walls and joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
External mastic in Thaxted: local notes
Historic houses like Horham Hall (about 1.8 miles south-west) are a reminder that the area around Thaxted has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St John the Baptist include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
Thaxted is about 6 miles south-east of Saffron Walden, in Essex. From the centre of Thaxted to the outskirts, external mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Our area takes in 644 places across Essex, large and small. There’s also a page for Chelmsford, about 16 miles away.

Leave it or put it right?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. In a smaller place like Thaxted, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. A visit to Thaxted is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

What we’re called out for in Thaxted
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
These are the problems we are asked about most:
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
Schools such as Thaxted Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
