About our external mastic in Norwood End
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on concrete & block, copings & trims and render & cladding joints, and the jobs we see most are joints pointed up with cement by mistake and hard, crazed mastic that has stopped moving.
Outside joints can only be sealed when they’re dry, so work in Norwood End is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What external mastic looks like in Norwood End
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Leave the joints unpainted unless we’ve said otherwise
- Act on the first splits you see
- Keep water from gutters off the wall
- Check external joints each spring
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Questions from Norwood End
What guarantee comes with external mastic in Norwood End?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do external mastic in Norwood End?
Yes, Norwood End is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Norwood End.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. In a small place like Norwood End, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- 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.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. Around Norwood End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Take a look at what affects the cost or what customers say.
Do you need external mastic in Norwood End?
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
The problems people normally mention when they call include:
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
- Weathered mastic that no longer stretches
Managing a site like The Ongar Academy? Then larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- Are they insured?
- What happens if the job turns out different
- Whether you can choose the colour
- How much experience the applicator has
What affects the quote in Norwood End
Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating
- The old material and how stubborn it is
- How many areas need sealing
- Access and height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:

- If it’s domestic, commercial or a hotel
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or email us.
