Signs you need external mastic in Chignall St James
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Look out for these signs:
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
- Failed sealant between panels on a façade
If you look after a building such as Newlands Spring Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How we handle external mastic in Chignall St James
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you are dealing with failed seals between different materials and movement joints with cracked, split or missing sealant, we can put it right, whatever the surface.
Somewhere as small as Chignall St James, 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.
Big or small, you get the same one-year guarantee in Chignall St James and across Essex.

Questions from Chignall St James
Will you come out to Chignall St James?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Chelmsford station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
How do I get a quote for external mastic in Chignall St James?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you have insurance?
Yes. We are fully insured.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
- Have failed joints looked at early
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
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
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Chignall St James, access is usually 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.
- Every bit of old sealant and any mortar or debris is cut out.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children

What external mastic looks like in Chignall St James
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Hylands (about 3.5 miles south) nearby, there’s older building stock in the area around Chignall St James as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Chelmsford station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Former Church of St James, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
How we quote for external mastic
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Working hours on commercial sites
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
Before you ask for a quote, have a think about:
- Where the property is
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- A few pictures by email, if you can
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.

Why it’s worth doing now in Chignall St James
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Where a wall is exposed, as many are in small places like Chignall St James, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
