External mastic in Aldborough Hatch
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you’re dealing with moss and dirt in joints with no sealant left and joints with sealant missing in places, we can help, whatever the surface.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
Whatever the size of the job, you get the same one-year guarantee in Aldborough Hatch and across Greater London.

Aldborough Hatch buildings and the weather
With historic houses such as Valentines Mansion (about 1.6 miles west) nearby, there’s older building stock in the area around Aldborough Hatch as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
As a London address, Aldborough Hatch can be tricky for parking: let us know about parking bays, permits or a driveway. Rented homes near Goodmayes station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Do you need external mastic in Aldborough Hatch?
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The problems people usually mention when they call are:
- Cracked joints where brick meets render or frames
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
- Rigid filler in a joint that should flex
If you live in an older home near Church of St Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why it’s worth doing now in Aldborough Hatch
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Aldborough Hatch, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- One-year guarantee on every job
- Sealant colour chosen to suit
- Fully insured
- White, clear, grey or coloured to suit, where the product allows

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Questions from Aldborough Hatch
Can you help a landlord with a rental near Goodmayes station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is parking a problem for a job in Aldborough Hatch?
Parking in Aldborough Hatch, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Do you cover Aldborough Hatch?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Aldborough Hatch.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Honest limits
We will not take on work that will not last, so these are the limits:
- Walls that need new movement joints cut into them
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
What we seal
- Copings & trims
- Concrete & block
- Façade panels
- Brickwork movement joints

- Joints between brick and frames
What we do, step by step
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. In Aldborough Hatch, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
