About our expansion joint sealing in Kennington
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. We work on podiums and floor movement joints, blockwork control joints and car park decks and ramps, and the usual reasons a site gets in touch are sealant pulling off the joint face and rain penetration at brick or block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kennington it comes down to the same thing: the right product in a properly prepared joint.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Joints that move: notes for Kennington
London car parks, loading bays and podium decks often can’t close for long, so joints are sealed in sections with each area handed back once cured. The 3 miles around Kennington take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
For a centre such as Southernwood Retail Park (2 miles east of Kennington), the service yard and car park joints normally need attention first. Sites like Gordon Hospital (to the north-west of Kennington) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Kennington is about 2 miles south-west of London, in Greater London. Our applicators travel to Kennington for work on movement joints. Kennington is one of 764 places in Greater London on our list for movement joints.

Questions about Kennington
Can you take on a job at a hospital such as Gordon Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Handel Business Centre, near Kennington, within your area?
Yes. Estates, retail parks and business parks around Kennington, Handel Business Centre among them, are all within reach. A few photographs and the unit address let us price the work.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you seal joints in cold or wet weather?
Weather matters for any external joint: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What sets the cost
Quotes vary with the job. Expect it to depend on:
- Quantities, in metres or numbers
- The site’s rules and procedures
- Working within restricted access windows
- How much existing material needs removing
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- Anything awkward about access or site hours
- Whether an asbestos survey exists
- The site address and postcode
- Drawings or a marked-up plan, if available
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email us.
Leave it or put it right?
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme because damage continues. We can split the scope into urgent and planned. Failed sealant in a building in Kennington can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Signs you need expansion joint sealing in Kennington
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.
Most enquiries start with something like this:
- Water dripping through deck or ramp joints
- New sealant over old, now failing
- Water getting into the wall through a failed joint
- Expansion joints split through the centre of the bead
A campus such as University of the Arts London (1.4 miles west of Kennington) has long runs of movement joint in its buildings, decks and paving.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
- What the guarantee covers, and for how long
- Do they follow the manufacturer’s priming guidance?
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Movement on a scale no sealant is meant to absorb
- Joints too narrow for the movement, which need redesigning by the engineer
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
Surfaces we seal

- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.

Before we start on site
