Why it’s worth doing now in Earls Colne
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Homes in smaller places like Earls Colne can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

How the job changes by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

How long does the job take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including the preparation. We’ll confirm how long when we quote.
How much does external mastic cost in Earls Colne?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do the sealants smell?

Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Earls Colne and the rest of Essex.
Do you need external mastic in Earls Colne?
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Common reasons people contact us include:
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
Rented homes near Chappel & Wakes Colne station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Make sure movement joints are not pointed over
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes anything from a few hours to several days, depending on the building, depending on the size of the job. In a smaller place like Earls Colne, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

Outside joints around Earls Colne
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Earls Colne Primary School and Nursery, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Parish Church of St Andrew, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
