How we handle expansion joint sealing in Poplar
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on brickwork movement joints, blockwork control joints and podiums and floor movement joints, and the failures we are asked to look at most are damp inside where a wall movement joint has failed and car park joints leaking onto vehicles below. Facilities teams, main contractors and managing agents in Poplar tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around Poplar, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we will come back to it.

Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Poplar can sit alongside others in a wider programme across Greater London.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
When to call us in Poplar
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.
Most enquiries start with something like this:
- Torn sealant in brick or block movement joints
- Brittle, chalky sealant on external joints
- Damp inside where a wall movement joint has failed
- Chipped joint edges on forklift routes
On a site such as Poplar Business Park, less than half a mile east of Poplar, the movement joints are in car park slabs, paving and building elevations.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- How they’ll work around occupants
- What the guarantee covers, and for how long
- Will CSCS-carded applicators be on site?
Why it’s worth doing now in Poplar
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open, compared with a full closure. We agree phasing with you before work starts. Getting scaffold, permits or access booked in Poplar takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.

On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself typically taking a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. In Poplar, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
- Agree which areas must stay open

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Crumbling edges that would give a new bead nothing sound to grip
- Changing the joint layout or spacing of a structure
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Surfaces we seal
- Cladding panel joints
- Precast concrete panel joints
- Podiums and floor movement joints
- Car park decks and ramps
- Brickwork movement joints
- Blockwork control joints
What affects the price in Poplar
These are the things that shape the price:
- How much there is to seal
- How much existing material needs removing
- Location, for remote and island sites
- Which sealant the job calls for
A quote for movement joints depends on quantities, condition and access. Ask us for a fixed quote.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Your programme or deadline
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
- The type of building and who uses it
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Common questions from Poplar clients
Do you take on work at healthcare sites like The London Independent Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Will you take on work at estates like Poplar Business Park, close to Poplar?
Yes. Estates, retail parks and business parks around Poplar, Poplar Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can the sealant be colour-matched?
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.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Warehouse floors and decks around Poplar
In London, decks, bays and service yards usually have to keep running, so the work is broken into short sections agreed with the building manager. The 3 miles around Poplar take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
At a retail site such as Manor Road Retail Park (1.3 miles north-east of Poplar), trolleys, cages and cars run over floor and slab joints all day. For an estate such as The London Independent Hospital, which lies north-west of Poplar, the joints in ramps, decks and long building elevations all need attention over time.
