Commercial clients in Kensington
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Kensington can form part of a wider programme.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
How we handle floor joint sealing in Kensington
Some joints reach us with their edges already broken. Filling against a crumbled arris won’t hold for long, so if the edges need repair before any filling, we’ll say so and leave that decision with you. The enquiries we see most involve drivers complaining about joints on a route and joint fill separating from the concrete, on forklift and pallet-truck routes, retail and showroom floors and construction joints. A specialist sealant contractor works differently from a general builder: in Kensington, that means joint design, primers and backing rod as standard.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Kensington means thinking about access, loading times and the ULEZ as well as the joints.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What else we do in Kensington
Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We look at joint widths, edge condition and the traffic on each route.
- A fixed quote follows, listing the treatment for each area and the order of work.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- We vacuum each run and prime it if the chosen product requires a primer.
- Filler or sealant goes in to the right depth and is finished flush with the slab.
- The area is handed back once it has cured enough to take traffic.
What we need from you
- Move anything stored against the joints
- Flag any permit to work we’ll need
- Explain the parking and delivery arrangements

Advice
Common questions from Kensington clients
Do you take on jobs in Kensington where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Can you work at a site such as Berghem Mews Business Village, by Kensington?
Yes, sites like Berghem Mews Business Village are within our area, along with the rest of Kensington. Send details of the unit and the work through our quote form for a quick quote.
Do you cover Kensington?
Yes. Sites across Kensington are covered.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Do you need floor joint sealing in Kensington?
Small, hard wheels put a lot of load through a very small area. Where a joint is open, the wheel dips and strikes the far edge and those knocks chip the edge apart bit by bit.
Any of the following is a good reason to get the joints checked over:
- Trucks and loads jolting over damaged joints
- Grimy joint lines spoiling a showroom floor
- Old filler gone hard, cracked or loose
- Loading bay joints breaking down
Campuses like University of Westminster, under half a mile south-west of Kensington, mix old and new buildings, with movement joints wherever they meet.
Comparing quotes
- The named product and why it was chosen
- Whether old or failed sealant will be cut out, not overlaid
- Their pre-qualification and accreditations
- How the joint faces will be prepared and primed
Surface by surface
Loading bays and dock areas
At loading bays, product choice has to suit the loads, the temperature and the wet. Curing times also have to fit around deliveries.
Isolation joints at walls and columns
We plan column and wall joints around racking and fixed plant so nothing has to move unexpectedly.
Quoting for work in Kensington
Your fixed quote is built from the real scope. It allows for:
- Access and working height
- The product specified
- Site requirements such as inductions and permits
- Working within restricted access windows
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Anything awkward about access or site hours
- The site address and postcode
- Any specification or named product
- The type of building and who uses it
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Joints that move: notes for Kensington
Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured. At least three named trading, business or retail sites lie within about 3 miles of Kensington. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Office parks like Berghem Mews Business Village, 0.7 miles to the west of Kensington, have decks, ramps and clad elevations whose joints take movement every day. At places like Stable Way Industrial Estate, 1.3 miles to the north-west of Kensington, joints are sealed a section at a time so operations carry on.
Kensington is about 5 miles west of London, in Greater London. We send applicators to Kensington for floor joints. We work across 764 places in Greater London.
Business premises anywhere in W11, W8, W14 and SW7 are within our area for floor joints. For a building on Kensington High Street, Edwardes Square and Somerset Square or nearby, we can quote for floor joints. You will find Kensington on or near the A402 and B316.
