How we handle external mastic in Thorington Street
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you’re dealing with movement joints with cracked, split or missing sealant and weathered mastic that no longer stretches, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Thorington Street is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What we are called out for in Thorington Street
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Keep an eye out for any of the following:
- Panel joints letting water in
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
Historic houses such as Castle House, about 3.7 miles south-east, show how far back building around Thorington Street goes.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are

What external mastic looks like in Thorington Street
With historic houses such as Castle House (about 3.7 miles south-east) nearby, there’s older building stock in the area around Thorington Street as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
In and around Thorington Street, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

FAQs for Thorington Street
Do you cover Thorington Street for external mastic?
Yes. Our work covers London and the South East, and Thorington Street is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Will you come out to Thorington Street?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Can landlords and businesses book you?
Yes, regularly. Several properties can go on one quote.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Thorington Street and the rest of Essex, along with the rest of our area.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Do you work at height?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Honest limits
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Brickwork movement joints

How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Thorington Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- 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.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
