External & façade joints in Church End, Essex
We cover Church End for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
External mastic in Church End, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on concrete & block, façade panels and brickwork movement joints, and people most often call us about movement joints filled with mortar instead of sealant and hard, crazed mastic that has stopped moving.
External sealant needs dry, clean surfaces, so work around Church End is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Church End questions
Will you come out to Church End?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Braintree station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
How much does external mastic cost in Church End?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Can you reach joints on upper floors?
Each building is different. Send us pictures and a rough idea of the height and we’ll confirm how they can be reached safely.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
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. The colour is chosen to suit.
Do you need external mastic in Church End?
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
The problems people normally mention when they call are:
- Sealant pulling away from one side of the joint
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
- Joints pointed up with cement by mistake
For an older house near a landmark such as Parish Church of St Andrew, an extension built onto an older house moves differently, and the joint between them takes the strain.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Point out the joints to other trades
- Wash walls gently around the sealant
- Keep soil, plants and ivy away from the joints
- Look over the joints every year, ideally after winter
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
What external mastic looks like in Church End
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Braintree station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Shalford Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Why deal with it now?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way and it means sorting access once. Older cottages and farmhouses around Church End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Church End, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on

Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
