About our external mastic in Saffron Walden
On houses, flats and commercial buildings across Saffron Walden, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Common call-outs are for rain getting behind render or cladding at a joint and old sealant gone brittle and cracked, across façade panels, copings & trims and render & cladding joints.
Extensions are a common sight on houses around Saffron Walden, and the line where an extension meets the original house is a common leak point. Getting the joint depth right matters as much as the sealant itself.
Whatever the size of the job, you get the same 12-month guarantee.

When to call us in Saffron Walden
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint.
Common reasons people contact us include:
- Moss and dirt in joints with no sealant left
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
- Failed seals between different materials
In the older streets around Saffron Walden Baptist Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How it works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building in most cases. Parking in a town like Saffron Walden is normally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Loose or hollow render, which needs re-rendering
- Damp that is not coming from the joint
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Copings & trims

Your questions about external mastic in Saffron Walden
Is there a guarantee on external mastic in Saffron Walden?
All our work, in Saffron Walden and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you do external mastic in Saffron Walden?
Yes. Our work covers London and the South East, and Saffron Walden is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
What do you need from me for a quote?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before we start.
How do I get a quote for external mastic in Saffron Walden?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can I do it myself?
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, and the work is guaranteed for a year.
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.
Saffron Walden buildings and the weather
Historic houses like Audley End House (about 1.1 miles west) are a reminder that the area around Saffron Walden 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as R A Butler Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Audley End station? Then split movement joints are easy to miss on a rental until damp shows inside.

How the job changes by surface
Joints between dissimilar materials

Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
