How we handle floor joint sealing in Coulsdon
We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Pricing depends on the length of joint, how worn the edges are and when we can get in, and the quote is fixed before we mobilise. The enquiries we see most involve broken arrises where pallet trucks cross and old filler gone hard, cracked or loose, on joints along racking aisles, saw-cut induced joints and construction joints. Looking for mastic applicators who cover Coulsdon? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
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.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

How the job changes by surface
Flexible floor sealants
A flexible sealant suits perimeter and movement joints away from the heaviest traffic. Backing rod limits how deep the bead goes and keeps it off the joint bottom.
Isolation joints at walls and columns
Perimeter and column joints get forgotten, and they collect dust and debris. We include them in the survey.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Wide or random cracking that suggests a structural issue
- Worn screed or surface finishes
- Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly before you book.
What we seal
- Joints along racking aisles
- Loading bays
- Construction joints
- Forklift and pallet-truck routes
- Saw-cut induced joints
- Retail and showroom floors
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Photograph any joint that starts to chip
- Walk the main routes and inspect joint lines on a regular cycle
- Plan for a top-up on newer floors
- Keep grit out of unfilled joints in the meantime
We’ll give you a time before trucks can run over the new joints and it pays to stick to it. In a busy building, barriers keep early traffic away.
Every day an open joint stays full of grit, the edges take more punishment. Getting it filled stops the damage before it becomes a repair.
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Common questions from Coulsdon clients
Do you take on work at healthcare sites like Purley War Memorial Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you take on jobs in Coulsdon where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How long before trucks can use the joints?
Cure times vary with the product and how cold the slab is. We’ll give you a time for each zone when we agree the phasing.
Do you repair broken joint edges?
Filling against broken edges doesn’t last. If the arrises have spalled, we will say they need repair before filling and set out how that affects the job.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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.
Why has the filler pulled away from one side?
Separation usually comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.

What else we do in Coulsdon
How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Planning a London job such as one in Coulsdon starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- You get a fixed quote with the product and the phasing set out.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- The area is handed back once it has cured enough to take traffic.
Preparing the site
- Send any specification or drawings in advance
- Make sure the joints can be reached
- Point out any areas we must not close

Advice
Leave it or put it right?
A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints, whether or not the floor is coated. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
