About our expansion joint sealing in Leafield
Mastic Doctor has sealed movement joints since 2005. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you are dealing with sealant peeling off one face of the joint and arrises breaking up along floor joints, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Leafield, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Leafield have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Jobs in and around smaller places like Leafield are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Let building users know which areas are affected
- Explain the parking and delivery arrangements

What sets the cost
The price varies from site to site. It mainly depends on:
- Working within restricted access windows
- Access and working height
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
A quote for movement joints depends on quantities, condition and access. Ask us for a fixed quote.
What we need to price the job
However big the job, these details speed things up:
- A wide shot and a close-up of the area
- Your programme or deadline
- Whether an asbestos survey exists
- Anything awkward about access or site hours
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Surface by surface
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal.
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What we are called out for in Leafield
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.
If one of these sounds familiar, it’s time for a closer look:
- Debris jammed in movement joints
- Movement joints with split or torn sealant
- Joints where the bead has lost adhesion
- Layers of sealant in a movement joint
Schools such as Leafield Church of England Primary School have movement joints in their walls and floors that are easy to overlook.
Questions to ask before you book
- How joint depth will be controlled
- Which product they’ll use, and why it suits the joint

FAQs: Leafield
Will our site in Leafield have to close for joint sealing?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.
Is Leafield off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Do the joint edges need to be sound before sealing?
Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Leave it or put it right?
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. Older rural buildings around Leafield move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Joints that move: notes for Leafield
Leafield lies roughly 66 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Rainfall across the South East, Leafield included, is lower than in many parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
For an occupier at a site such as Crawley Mill Industrial Estate (2.5 miles south-east of Leafield), the joints at loading doors and dock levellers normally see the hardest wear. Phasing is what makes joint work possible on busy sites such as Manor Barns Business Park (2.8 miles east of Leafield): one bay, aisle or car park row at a time.
