How we handle external mastic in Tottenham Hale
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on concrete & block, copings & trims and joints between brick and frames, and common reasons people get in touch are sealant that has lost its bond to the brick or render and water getting into walls through failed joints.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Signs you need external mastic in Tottenham Hale
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Look out for any of the following:
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
- Rigid filler in a joint that should flex
Rented homes near Tottenham Hale station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- Who does the work, and how experienced they are
- The length of the guarantee
- Is the old sealant removed completely?
- What insurance they hold
How we quote for external mastic
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Helping us quote
When you contact us, it’s useful to know:
- How we’d reach the joints
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
External mastic in Tottenham Hale: local notes
With historic houses such as Bruce Castle (about 1 mile north-west) nearby, there’s older building stock in the area around Tottenham Hale as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Ferry Lane Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Tottenham Hale is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a flat in Tottenham Hale, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
