Floor joint sealing across North Cheam
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. 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.
- A floor survey records every joint, its edges and what crosses it.
- You receive a fixed quote showing products and phasing.
- Old fill and packed debris come out until both faces are sound.
- Dust is vacuumed out and primer applied where specified.
- Filler or sealant is placed to depth and finished flush.
- We hand each phase back when it can take traffic.
Getting the site ready
- Tell staff and tenants when we will be in
- Flag any permit to work we’ll need
- Share the asbestos register for older buildings

Floor joint sealing for commercial buildings in North Cheam
Mastic Doctor has worked on joints in commercial buildings for over 20 years. Applicators carry CSCS cards and work to your site rules, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. We work on retail and showroom floors, saw-cut induced joints and forklift and pallet-truck routes, and the usual reasons a site gets in touch are open saw cuts full of debris and failing joints at loading bays and dock doors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in North Cheam it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What else we do in North Cheam
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in North Cheam can sit alongside others in a wider programme.
Signs you need floor joint sealing in North Cheam
A slab keeps shrinking for a long time after it is cast, and the saw cuts are there so it cracks in straight, controlled lines. As the panels contract, the joints widen, and a filler placed early can part company with one face.
It’s worth sending us details if you spot any of the following:
- Untidy open joints in a retail unit
- Loading bay joints breaking down
- Flexible sealant torn out by wheels
- Saw-cut joints left open and packed with grit
Across sites such as Beverley Trading Estate (1 mile north of North Cheam), floor and movement joints can be sealed in phases so units keep working.
What to look for in a quote
- Their approach to joint depth and backing
- Their public liability cover
- Whether their applicators hold CSCS cards
- Whether primer will be used where the manufacturer specifies it
FAQs: North Cheam
Is hospital work, at somewhere like Queen Mary's Childrens' Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you work in London buildings with loading restrictions?
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.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you repair broken joint edges?
We check the edges as part of the survey. Damaged edges are flagged up front, so nothing is filled that won’t hold.
Will we need to close the floor?
Normally only the zone we are working in has to close. Each zone reopens when the product can take traffic and the next zone follows.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Floor joint sealing in North Cheam: the local picture
London car parks, loading bays and podium decks often can’t close for long, 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 North Cheam. Their warehouses, yards and car parks are exactly where joints take the most punishment.
A campus such as University for the Creative Arts (to the south-west of North Cheam) has long runs of movement joint in its buildings, decks and paving. Hospitals like Queen Mary's Childrens' Hospital (1.6 miles east of North Cheam) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Structural cracking in the slab
- A floor that is out of level for the racking or trucks
- Spalled arrises, which need an edge repair first
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Surfaces we seal
- Forklift and pallet-truck routes
- Saw-cut induced joints
- Loading bays
- Joints along racking aisles
- Retail and showroom floors
- Construction joints
Why it’s worth doing now in North Cheam
Tape, or whatever sealant is in the stores cupboard, may look like a fix for a while. None of it is designed for wheel loads and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
