Expansion joint sealing in Tottenham
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. Most enquiries involve torn sealant in brick or block movement joints and arrises breaking up along floor joints, across car park decks and ramps, cladding panel joints and precast concrete panel joints. Searching for sealant specialists in Tottenham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around Tottenham, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Tottenham
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach, and we’ll say so before quoting. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Pricing movement joints depends on quantities, condition and access. Call for a quote.

Read our cost guide and how we’re accredited.
What sets the cost
Before we quote, we look at:
- Location, for remote and island sites
- The total length or number of joints
- Any access equipment needed
- Whether old sealant has to be cut out first
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- The type of building and who uses it
- How the joints are reached, and at what height
- Whether an asbestos survey exists
- Any specification or named product
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email us.
Questions we are asked in Tottenham
Would you work within a site like North Middlesex University Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Rosebery Industrial Park, near Tottenham?
Yes. Our area takes in Tottenham and its surroundings, with estates and business parks such as Rosebery Industrial Park included. Send details of the unit and the work through our quote form for a quick quote.
Do you use silicone or polyurethane in movement joints?
Movement capability matters most. Where two different materials meet, a hybrid sealant can be the better choice.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Include photos or drawings if you have them.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Expansion joint sealing in Tottenham: the local picture
Basement car parks and service yards in London tend to be in use all working day, so joints are sealed in sections with each area handed back once cured. Less than 3 miles from Tottenham there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Large sites such as North Middlesex University Hospital, 1.1 miles to the north of Tottenham, have car parks, service roads and long elevations with movement joints in brick and panels. For a centre such as Tottenham Hale Retail Park, 0.8 miles to the south of Tottenham, the service yard and car park joints normally need attention first.

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. 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.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
Request a quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Related advice
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Look over external and deck joints after a hard winter
- Act on the first tear or lifting edge rather than waiting
- Leave barriers in place until fresh joint sealant has cured
- Avoid parking heavy plant or pallets on joint lines
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. A routine sweep is the simplest protection.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
