Honest limits
We’ll always be straight with you, so here’s what new sealant will not do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that is more than a sealant joint can take
- Loose or hollow render, which needs re-rendering

External mastic for homes and businesses in Rayne
For buildings in Rayne, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We are often asked to deal with failed sealant between panels on a façade and joints where the bead has come unstuck, across brickwork movement joints, concrete & block and copings & trims.
In a village or hamlet like Rayne, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, you get the same 12-month guarantee.

How we quote for external mastic
We do not publish a price list, because jobs vary so much. What we look at:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The size of the job
- The product the joint needs
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Whether it has been sealed before
For a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.
How to look after the new joints
After the cure time, these simple habits help:
- Tell anyone working on the walls about the movement joints
- Make sure movement joints aren’t pointed over
- Act on the first splits you see
- Keep water from gutters off the wall
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.
What happens on the day
At the end, we look at the finished work together. The visit itself generally takes anything from a few hours to several days, depending on the building, depending on the amount of work. In a small place like Rayne, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Move anything stored near the joints

Rayne questions
Is Rayne within the area you cover?
Yes. Rayne is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do external mastic in Rayne?
Yes. We work across London and the South East, and Rayne is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you have insurance?
Yes. We’re fully insured for every job we do.
What does external mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Signs you need external mastic in Rayne
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Look out for any of the following:
- Cracked joints where brick meets render or frames
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
In the older streets around Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before booking
- What preparation is included
- What insurance they hold

- Which sealant they’ll use, and why

Outside joints around Rayne
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Braintree station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Rayne Primary and Nursery School, its movement joints, gutters and trims need looking after like any other building’s.
