Expansion joint sealing in Kennington
Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. If you have sealant peeling off one face of the joint and leaks through car park deck joints onto the level below, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Kennington tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Rural business units around smaller places such as Kennington often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Common problems we fix in Kennington
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.
It’s worth sending us details if you spot any of the following:
- Debris jammed in movement joints
- Car park joints leaking onto vehicles below
- Arrises breaking up along floor joints
- Water getting into the wall through a failed joint
Hospital campuses such as The One Ashford Hospital, 2 miles south-east of Kennington, grow in stages, leaving movement joints wherever new blocks meet old.
Questions to ask before you book
- Their pre-qualification and accreditations
- Do they follow the manufacturer’s priming guidance?
- Whether old or failed sealant will be cut out, not overlaid
- Who will actually carry out the work
What the job involves on each surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.
How a job runs
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a job in Kennington, the main thing is a clear picture of the work. You will then get a fixed price for the work.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- 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.
Preparing the site
- Tell us which areas need to stay in use
- Have the specification and drawings to hand
- Arrange parking or a loading space

Kennington: questions and answers
Is Kennington too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on work at healthcare sites like The One Ashford Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Why do our movement joints keep failing?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing since each needs a different fix.
Can you work while the building is occupied?
Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
How do I request a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Looking after the joints
A few simple habits keep the new joints working:
- Report split or peeling joint sealant early
- Reopen bays and walkways only after the stated cure time
- Inspect exposed joints once the cold weather has passed
- Keep racking legs and heavy point loads off floor joints
Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.
Expansion joint sealing in Kennington: the local picture
The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. Kennington is about 48 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.
On a site such as Eurogate Business Park, 0.8 miles to the west of Kennington, the movement joints are in car park slabs, paving and building elevations. In a school such as Kennington Church of England Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.
