External mastic in Baker Street
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. Typical jobs include joints where the bead has come unstuck and rain getting behind render or cladding at a joint, on façade panels, joints between brick and frames and brickwork movement joints.
Outside joints can only be sealed when they’re dry, so work in Baker Street is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Our work is backed for twelve months.

Questions from Baker Street
Do you work for landlords with property near Grays station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Is Baker Street in your area for external mastic?
Yes. We work across London and the South East, and Baker Street is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
How much does external mastic cost in Baker Street?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it doesn’t stand out.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Outside joints around Baker Street
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Orsett Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near St Giles & All Saints Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Grays station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Baker Street, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
Before we arrive
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Honest limits
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:
- Damp that isn’t coming from the joint
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Copings & trims
- Façade panels
- Joints between brick and frames
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we have said otherwise
- Have failed joints looked at early
- Make sure movement joints are not pointed over
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

What affects the quote in Baker Street
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- The number of rooms or windows
- Mould in or behind the old joints
- Access and height
Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Asking for a quote
When you contact us, these details help:
- The address or postcode of the job
- Photos by email, if that’s easy
- Whether it has been sealed before
- Roughly how big the job is
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or send us an email.
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a small place like Baker Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
