About our external mastic in Hatton
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you have movement joints filled with mortar instead of sealant and gaps where render, brick and frames meet, we can put it right.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Hatton, check the lease for who looks after the outside.
Each job carries a 12-month guarantee.

Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Tell us what the building has when you get in touch.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Common questions in Hatton
Do you work for landlords with property near Heathrow Terminal 4 Rail station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is parking a problem for a job in Hatton?
Parking in Hatton, 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.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you come to Hatton?
We do. Hatton is part of the area we cover.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
DIY sealant or a professional job?
If you are set on DIY, put the effort into 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Looking after it afterwards
To keep the joints looking good and working properly:
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
- Show decorators and builders where the movement joints are
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the building. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Hatton. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Keep children and pets away from the work area

What affects the cost of external mastic
There’s no set price list, because no two jobs are the same. What we look at:
- How many rooms, windows or areas are involved
- The product the joint needs
- The size of the job
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit normally makes better use of the time than several visits. We’ll send you a clear quote for the lot.

Hatton buildings and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
As a London address, Hatton can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Cranford Primary School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to The Parish Church of the Good Shepherd include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
