Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Mention any aggressive cleaning regime at quote stage
- Walk the main routes and inspect joint lines on a regular cycle
- Clear packed debris from open joints regularly
- Plan for a top-up on newer floors
Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it.
Joints are easiest to look after when someone checks them regularly. We can quote a programme that starts with the busiest areas so nothing is left to fail.

Mastic Doctor has worked on joints in commercial buildings for over 20 years.

One point of contact handles commercial sealant work in Selsdon from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around Selsdon, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Why deal with it now?
An open joint is a modest filling job while its edges are sound. Left until they break, it needs an edge repair before any filling can start, with longer closures to match. In Selsdon, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

FAQs: Selsdon
Do you take on jobs in Selsdon where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Does your area include sites such as Capital Business Centre, near Selsdon?
Yes. Our area takes in Selsdon and its surroundings, with estates and business parks such as Capital Business Centre included. A few photos and the unit address let us price the work.
Why has the filler pulled away from one side?
On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. A top-up normally puts it right.
How long before trucks can use the joints?
Cure times vary with the product and how cold the slab is. You will get a reopening time for each area before we start.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Do you repair broken joint edges?
A filler needs sound edges to grip. If the arrises have spalled, we will say they need repair before filling, so you can decide how to proceed.
Should floor joints be filled or sealed?
There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is usually right and perimeter or movement joints need flexibility. You will see the choice for each area in the quote.

Where floor joints take the most wear near Selsdon
Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures. The 3 miles around Selsdon take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Another example is Twin Bridges Business Park (1.8 miles west of Selsdon), where floors and yards would be done in stages around the occupiers. At a retail site such as Whitgift Centre, which lies north-west of Selsdon, trolleys, cages and cars run over floor and slab joints all day. Sites like Shirley Oaks Hospital, 2.6 miles north of Selsdon, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Surface by surface
Semi-rigid joint fillers
A semi-rigid filler is stiff enough to hold the arrises up when wheels cross. They allow only small movement so timing matters on newer slabs.
Retail and showroom floors
We plan shop-floor work so trading can continue. Tell us your site hours and access windows and we’ll plan around them.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We look at joint widths, edge condition and the traffic on each route.
- You get a fixed quote with the product and the phasing set out.
- We remove failed material and packed debris until sound concrete is exposed on both faces.
- We vacuum each run and prime it if the chosen product requires a primer.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- We tell you when each zone can carry trucks again and move on to the next.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
