About our expansion joint sealing in Broadwater Farm
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. We work on brickwork movement joints, car park decks and ramps and cladding panel joints, and what we are called in for most is car park joints leaking onto vehicles below and rain penetration at brick or block movement joints. Searching for sealant specialists in Broadwater Farm? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Broadwater Farm, as everywhere in London, access, loading and the ULEZ all come into the plan.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Joints that move: notes for Broadwater Farm
Broadwater Farm has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures.
Hospital campuses such as St Ann's Hospital, 1 mile to the south of Broadwater Farm, grow in stages, leaving movement joints wherever new blocks meet old. Places like Tottenham Hale Retail Park (to the south-east of Broadwater Farm) put trolleys over floor joints inside and cars over slab joints outside.

Do you need expansion joint sealing in Broadwater Farm?
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.
These are often picked up first by site or facilities staff:
- Expansion joints split through the centre of the bead
- Damp inside where a wall movement joint has failed
- New sealant over old, now failing
- Chipped joint edges on forklift routes
Schools like The Willow Primary School often have long brick elevations with movement joints that age quietly.
What your quote should include
- What level of public liability insurance do they hold?
- The terms of the workmanship guarantee
- Whether their applicators hold CSCS cards
- Whether old or failed sealant will be cut out, not overlaid
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we will need
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

What sets the cost
We price every job individually. The main factors are:
- The total length or number of joints
- Backing rod, priming and other preparation
- Distance, for remote addresses
- Site requirements such as inductions and permits
A quote for movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- Where the site is, with the postcode
- Photos of the joints, close up and from further back
- Your programme or deadline
- The type of building and who uses it

What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. In Broadwater Farm, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why us?

Maintenance after handover
For the best life from the joints:
- Keep stones and debris out of open joint lines
- Keep traffic off new joints until the cure time is up
- Put movement joints on the planned maintenance inspection round
- Record the sealant used and the date in the O&M file
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.
FAQs: Broadwater Farm
Can you work at a site such as Tottenham Hale Retail Park, by Broadwater Farm?
Yes. We cover Broadwater Farm and the area around it, including industrial estates, business parks and retail parks such as Tottenham Hale Retail Park. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can staff carry on working while you are here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting.
Can you work on car park ramps and decks?
Yes. Tell us how the car park is used and which areas must stay open.
