Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. In Kevington, 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.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints

Expansion joint sealing in Kevington
We’ve been sealing expansion and movement joints for over 20 years. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. Most enquiries involve brittle, chalky sealant on external joints and water getting into the wall through a failed joint, across precast concrete panel joints, brickwork movement joints and blockwork control joints. One point of contact handles commercial sealant work in Kevington from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up, so it pays to act early.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Joints that move: notes for Kevington
Kevington has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager.
At places like Brook Industrial Estate (1.2 miles north-west of Kevington), joints are sealed a section at a time so operations carry on. University campuses such as University of Greenwich Avery Hill Campus, 4.8 miles north-west of Kevington, have car parks, paved walkways and building elevations with movement joints.
Kevington is about 1 mile east of Orpington, in Greater London. Across the BR5 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places, from busy centres to rural villages. There’s a separate page for London, about 13 miles away.
Postcode districts covered here: BR5 for movement joints. For a building on Crockenhill Road and Sheepcote Lane or nearby, send details and we will quote for movement joints. We also cover Derry Downs (1 mile west), Crockenhill (1 mile east), St Mary Cray (1 mile west), Orpington (1 mile west) and Poverest (2 miles west) for movement joints. Nearby towns on our patch include London (13 miles north-west), City of Westminster (15 miles north-west), Marylebone (15 miles north-west), St Pancras (15 miles north-west), Shoreditch (13 miles north-west) and Walthamstow (15 miles north-west).
Local landmarks in Kevington
Locally, jobs take us to sites close to The Priory School and Harris Academy Orpington and the streets around them. For rail, the closest station is St Mary Cray station, roughly 1.4 miles north-west. Other landmarks nearby include Lullingstone Castle (3.2 miles south-east) and London Borough of Bromley Museum (1.5 miles west). Not far away are Summer Hill and The Warren.
What sets the cost
These are the things that shape the price:
- The total length or number of joints
- The product specified
- Any access equipment needed
- Joint width, depth and condition
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What we need to price the job
However big the job, these details speed things up:
- Whether an asbestos survey exists
- When you need the work done
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email us.
What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. We agree phasing with you before work starts. Failed sealant in a building in Kevington can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

How the job changes by surface
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal.
