Floor joint sealing in Catford
Mastic Doctor has worked on joints in commercial buildings for over 20 years. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member holding public liability insurance. Completed joints come with a 12-month guarantee on our workmanship. Site teams most often ask us about old filler gone hard, cracked or loose and scruffy, dirty joint lines on a shop or showroom floor, on loading bays, joints along racking aisles and saw-cut induced joints. Searching for sealant specialists in Catford? We’ve been sealing commercial buildings since 2005.
Areas such as a loading bay or car park deck in Catford typically have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Common questions from Catford clients
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Is a hospital such as University Hospital Lewisham somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How long before trucks can use the joints?
Each product has its own cure time, and cold floors slow it down. Phasing is planned with that in mind.
Should floor joints be filled or sealed?
We decide joint by joint. Where hard wheels cross, a semi-rigid filler is usually right, and movement joints or perimeters need something flexible. The quote sets out what goes where.
How the quote is worked out
To price the job, we consider:
- Whether the work must be split into stages
- The size and state of each joint
- Location, for remote and island sites
- Quantities, in metres or numbers
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Sending details for a quote
A few photographs plus some basic facts will normally do. It helps to include:
- What the building is and how it’s used
- When you need the work done
- Specification clauses that apply
- Photos of the joints, close up and from further back
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or send details through our quote form.
Common problems we fix in Catford
Left open, joints fill with grit, wrap and wood fragments. Packed debris acts like a wedge every time a wheel crosses, speeding up the damage.
Look out for the following:
- Brittle joint filler breaking up
- Open saw cuts full of debris
- Chipped and spalling edges along forklift routes
- A rough ride across broken joints
Schools like Holy Cross Catholic Primary School often have long brick elevations with movement joints that age quietly.

Why act early in Catford
Tape, or whatever sealant is in the stores cupboard, may look like a fix for a while. Neither is made to carry wheels and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. In Catford, 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.
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’ll have a fixed figure to work with.

Doing it in-house
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.
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 where general trades tend to cut corners.
Traffic, movement and joints around Catford
Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures. Catford has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Another example is Chiltonian Industrial Estate, 1.2 miles north-east of Catford, where floors and yards would be done in stages around the occupiers. University campuses such as University of Greenwich - Greenwich Campus (to the north of Catford) have car parks, paved walkways and building elevations with movement joints.
