How we quote for external mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- How many areas need sealing
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Access and height
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- The address or postcode of the job
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
External mastic for homes and businesses in Upper Burgate
On houses, flats and commercial buildings across Upper Burgate, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have joints pointed up with cement by mistake and hard, crazed mastic that has stopped moving, we can put it right, whatever the surface.
Somewhere as small as Upper Burgate, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Questions from Upper Burgate
Will you come out to Upper Burgate?
Yes. Upper Burgate is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Upper Burgate in your area for external mastic?
Yes. Our work covers London and the South East, and Upper Burgate is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Are you insured?
Yes, we’re fully insured.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why it’s worth doing now in Upper Burgate
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way. In a small place like Upper Burgate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. For a village or hamlet like Upper Burgate, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

Related advice
Walls and rooflines in Upper Burgate
Historic houses like Breamore House (about 1.6 miles north) are a reminder that the area around Upper Burgate has older buildings as well as new. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Woodgreen Methodist Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Leave the joints unpainted unless we’ve said otherwise
- Keep water from gutters off the wall
- Tell anyone working on the walls about the movement joints
- Keep soil, plants and ivy away from the joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.

Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant is not too deep.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
What we’re called out for in Upper Burgate
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
People generally contact us when they notice something like this:
- Rain getting behind render or cladding at a joint
- Panel joints letting water in
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
For site and facilities teams at buildings such as The Burgate School and Sixth Form, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before you book
- Is VAT in the price?
- What product goes in the joint
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
When something else is needed
In fairness, some problems need a different trade:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
