How we handle expansion joint sealing in Shoreditch
Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. The enquiries we see most involve weathered movement joint sealant that no longer flexes and car park joints leaking onto vehicles below, across brickwork movement joints, car park decks and ramps and cladding panel joints. Searching for sealant specialists in Shoreditch? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Shoreditch, as everywhere in London, access, loading and the ULEZ all come into the plan.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
What sets the cost
Each job is priced on its own details. The main factors are:
- Which sealant the job calls for
- The size and state of each joint
- Whether old sealant has to be cut out first
- Access and working height
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
We can often quote from photographs and a few details. Please tell us:
- Anything awkward about access or site hours
- The postcode of the building
- Any specification or named product
- The asbestos register, for older buildings
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email the details over.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Include every elevation and deck joint in periodic inspections
- Note which joints were done, when, and with what
- Keep scrapers and ploughs from dragging across joint sealant
- Keep traffic off new joints until the cure time is up
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.
How the job changes by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed.
Your questions answered
Is Anchor Retail Park, near Shoreditch, within your area?
Yes. We cover Shoreditch and the area around it, including industrial estates, business parks and retail parks such as Anchor Retail Park. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you work on a hospital site such as Mildmay Mission Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
What will the job cost?
Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or use the quote form with a description of the work.
Leave it or put it right?
A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Floors, slabs and movement joints in Shoreditch
The 3 miles around Shoreditch 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. Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured.
For a school such as Virginia Primary School, playground and building joints can be done in the holidays. For a store at a site such as Anchor Retail Park (1.2 miles east of Shoreditch), the service yard and goods-in area are where joints break down first. Hospitals like Mildmay Mission Hospital (to the north-east of Shoreditch) have multi-storey or surface car parks whose joints carry vehicles round the clock.
Shoreditch is about 2 miles north of London, in Greater London. We cover Shoreditch, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Shoreditch is one of 764 places in Greater London on our list.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in Shoreditch can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Send any specification or drawings in advance
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
