About our floor joint sealing in Chelsea Harbour
Concrete floors in warehouses and factories are cut into bays with saw cuts and day joints, and each joint line is a weak edge that wheels run over all day. Our job is to put the right filler or sealant into them for the loads and the movement they see so the edges are held up and debris can’t pack in. If you’re dealing with filler that has parted from one face and broken arrises where pallet trucks cross, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Chelsea Harbour tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Areas such as a loading bay or car park deck in Chelsea Harbour normally have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

How a job runs
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We walk the floor and mark up joint widths, edge damage and traffic routes.
- You receive a fixed quote showing products and phasing.
- Old fill and packed debris come out until both faces are sound.
- We extract the dust and prime the faces if the product needs it.
- The joint is filled to its specified depth and trimmed level.
- We hand each phase back when it can take traffic.
Before we start on site
- Tell staff and tenants when we’ll be in
- Let us know about inductions and permits
- Tell us your opening times and when work is allowed

Common problems we fix in Chelsea Harbour
Floor joints collect dust, oil, curing compound and cleaning residue. Without cutting back to sound, clean concrete the new filler can’t stay bonded.
Typical triggers for a call:
- Flexible sealant torn out by wheels
- A gap opening alongside old joint filler
- Unfilled floor joints collecting dirt and grit
- Joint edges breaking up under truck wheels
Business parks such as Town Mead Business Centre (to the south of Chelsea Harbour) have car parks, paved areas and long brick and panel elevations, all with movement joints.
What your quote should include
- The terms of the workmanship guarantee
- How joint depth will be controlled
- How they handle RAMS and site documents
- Do they follow the manufacturer’s priming guidance?
FAQs: Chelsea Harbour
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Is a hospital such as Chelsea and Westminster Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How soon can traffic go back on the floor?
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 if there’s asbestos in the old mastic?
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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What do you need from us to quote?
A rough joint length, a few photographs and a site plan are typically enough for a quick quote. We can visit where that helps so call 01277 525 020 or email a schedule or drawings to set one up.
Why act early in Chelsea Harbour
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 which means more downtime in that zone. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Structural cracking in the slab
- Spalled arrises, which need an edge repair first
- A floor that is out of level for the racking or trucks
If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think.
What we seal
- Joints along racking aisles
- Construction joints
- Loading bays
- Retail and showroom floors
- Saw-cut induced joints
- Forklift and pallet-truck routes
Site staff or a sealant specialist?
Certain joints really need a specialist: 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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What affects the price in Chelsea Harbour
Each job is priced on its own details. The things that drive the figure:
- How accessible the joints are
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- The size and state of each joint
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Photos of the joints, close up and from further back
- The product your specification calls for
- When you need the work done
- Whether the building will be occupied during the work
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
