External & façade joints in Cowey Green, Essex
Movement joints in Cowey Green need attention? We remove the old material, prepare the joints and seal them properly.
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Failed sealant between panels on a façade
How we handle external mastic in Cowey Green
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. Common call-outs are for hard, crazed mastic that has stopped moving and movement joints with cracked, split or missing sealant, on render & cladding joints, copings & trims and concrete & block.
Somewhere as small as Cowey Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a 12-month guarantee.

How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- When we can work, for business premises
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Helping us quote
When you contact us, these details help:
- If someone has resealed it before
- Any access issues, like height or stairs
- The rough size of the job
- Whether it’s a home or a business
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
- Damp that is not coming from the joint
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Façade panels
- Concrete & block

Cowey Green buildings and the weather
With historic houses such as Castle House (about 4.5 miles north-west) nearby, there’s older building stock in the area around Cowey Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Schools such as St George's Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St George, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Great Bentley station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

How it works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building in most cases. Somewhere as small as Cowey Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- 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.
Before we arrive

- Try not to wet indoor joints just before the visit
- Clear the area around the work

Why act early in Cowey Green
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Cowey Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.

What the job involves on each surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Cowey Green questions
Will you come out to Cowey Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Cowey Green in your area for external mastic?
Yes. We work across London and the South East, and Cowey Green is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
How much does external mastic cost in Cowey Green?
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.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
How long does the job take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including the preparation. We will confirm how long when we quote.
Can new sealant go over the old?
No. The old sealant always comes out first.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
