How we handle expansion joint sealing in Heron Quays
Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. We work on podiums and floor movement joints, cladding panel joints and precast concrete panel joints, and the usual reasons a site gets in touch are spalled or broken joint edges in floors and decks and leaks through car park deck joints onto the level below. Searching for sealant specialists in Heron Quays? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Heron Quays, as everywhere in London, access, loading and the ULEZ all come into the plan.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Looking after the joints
For the best life from the joints:
- Plan racking layouts so feet don’t land on a joint
- Include every elevation and deck joint in periodic inspections
- Reopen bays and walkways only after the stated cure time
- Note which joints were done, when, and with what
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.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
From enquiry to sign-off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Share the asbestos register for older buildings
- Warn occupants and staff about the work
- Explain the parking and delivery arrangements

Advice
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Leaks coming from the membrane rather than the joint seal
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Changing the joint layout or spacing of a structure
Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly.
Joints and surfaces we work on

Signs you need expansion joint sealing in Heron Quays
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.
Typical triggers for a call:
- Expansion joints split through the centre of the bead
- New sealant over old, now failing
- Sealant peeling off one face of the joint
- Water getting into the wall through a failed joint
For a centre such as Surrey Quays Shopping Centre, 1.2 miles south-west of Heron Quays, the service yard and car park joints normally need attention first.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?

Does the weather affect joint sealing?
Weather matters for any external joint: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How much does the work cost?
There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.
What exactly is a movement joint?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading.
