About our external mastic in Brookstreet
For buildings in Brookstreet, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Typical jobs include brick movement joints where the sealant has split and water getting into walls through failed joints, across render & cladding joints, copings & trims and joints between brick and frames.
External sealant needs dry, clean surfaces, so work around Brookstreet is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Whatever the size of the job, it’s backed by our 12-month guarantee in Brookstreet and across Essex.

When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Movement that is more than a sealant joint can take
- Adding movement joints to masonry that has none
- Render that’s blown, hollow or coming away

What the job involves on each surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Brookstreet: your questions answered
Is Brookstreet within the area you cover?
Yes. Brookstreet is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is external mastic in Brookstreet guaranteed?

Do you have insurance?
Yes. We are fully insured.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What is a movement joint?
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 do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Why deal with it now?
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. In a small place like Brookstreet, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.
Why book with us
- Experience in homes, commercial sites and hotels
- Any old sealant cut out fully, not covered over
- White, clear, grey or coloured to suit, where the product allows
- Sealant colour chosen to suit

What happens on the day
At the end, we look at the finished work together. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. Somewhere like Brookstreet needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Let us know about parking restrictions
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

When to call us in Brookstreet
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we’re asked about most:
- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
Managing a site like The Flitch Green Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- Whether they seal over old material or remove it
- What guarantee comes with the work
- Whether the sealant suits the joint

External mastic in Brookstreet: local notes
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.
In the older streets around Church of St Mary the Virgin, an extension built onto an older house moves differently, and the joint between them takes the strain.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Look over the joints every year, ideally after winter
- Wash walls gently around the sealant
- Keep soil, plants and ivy away from the joints
- Keep water from gutters off the wall
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
