Traffic, movement and joints around Bell Green
Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time. Bell Green has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Hospitals like University Hospital Lewisham (1.7 miles north-east of Bell Green) have multi-storey or surface car parks whose joints carry vehicles round the clock. Phasing is what makes joint work possible on busy sites such as Clyde Vale Industrial Estate (1 mile west of Bell Green): one bay, aisle or car park row at a time. Schools such as Haseltine Primary School have movement joints in their walls and floors that are easy to overlook.

Expansion joint sealing for commercial buildings in Bell Green
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Bell Green. We work on cladding panel joints, brickwork movement joints and precast concrete panel joints, and the failures we are asked to look at most are sealant peeling off one face of the joint and brittle, chalky sealant on external joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Bell Green, preparation and product choice get the time they need.
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.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. 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 assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Agree which areas must stay open
- Have the specification and drawings to hand
- Warn occupants and staff about the work

What the job involves on each surface
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit.
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

What sets the cost
The price varies from site to site. It mainly depends on:
- Removal of failed or old sealant
- Location, for remote and island sites
- Joint width, depth and condition
- Access and working height
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- The asbestos register, for older buildings
- Whether the building will be occupied during the work
- Specification clauses that apply
- Anything awkward about access or site hours
For a fixed quote, ring 01277 525 020 or send details through our quote form. You can also send details through our quote form.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Leaks coming from the membrane rather than the joint seal
- Changing the joint layout or spacing of a structure
- Movement on a scale no sealant is meant to absorb
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Car park decks and ramps
- Precast concrete panel joints
- Cladding panel joints
- Blockwork control joints
- Podiums and floor movement joints
- Brickwork movement joints
Leave it or put it right?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too, and a second visit means paying for access again. We can price a patch and a full reseal side by side. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Bell Green: questions and answers
Can you work on a hospital site such as University Hospital Lewisham?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.
Can the sealant be colour-matched?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
How long will the joint resealing take?
It typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote along with the phasing plan.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
