How we handle external mastic in Brick End
For buildings in Brick End, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Typical jobs include movement joints filled with mortar instead of sealant and water getting into walls through failed joints, on render & cladding joints, concrete & block and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Brick End is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
Why act early in Brick End
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Older cottages and farmhouses around Brick End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: 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.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What sealant work can’t fix
Before booking, it’s worth knowing the limits too:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Brick End buildings and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Horham Hall (about 2.4 miles north-east) are a reminder that the area around Brick End 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.
Letting a property close to Stansted Airport station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Brick End
Can you help a landlord with a rental near Stansted Airport station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Can you do external mastic in Brick End?
Yes. We work across London and the South East, and Brick End is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
How it works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Brick End, access is often the only tricky part. 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.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
