Expansion joint sealing in Hazelwood
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1, and the bead is tooled so it grips the two faces alone. We work on blockwork control joints, podiums and floor movement joints and brickwork movement joints, and the usual reasons a site gets in touch are car park joints leaking onto vehicles below and damp inside where a wall movement joint has failed. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hazelwood is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Hazelwood, as everywhere in London, access, loading and the ULEZ all come into the plan.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Floors, slabs and movement joints in Hazelwood
Two named trading, business or retail sites lie within about 3 miles of Hazelwood. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. 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.
Like every part of Greater London, Hazelwood is covered by the ULEZ, so vehicle access, loading and parking are planned before the first visit. Schools like Downe Primary School often have long brick elevations with movement joints that age quietly.
Hazelwood is about 4 miles south of Orpington, in Greater London. We cover Hazelwood, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 764 places across Greater London fall within our area, Hazelwood among them. Our London page has more on work in that area, about 14 miles away.
Commercial sites across TN14 are covered for movement joints. Streets here include Hazelwood Road, Cudham Lane North and Spinney Way. Just outside Hazelwood, we also work in Downe (1 mile west), Luxted (1 mile south-west), Cudham (1 mile south), Single Street (1 mile south-west) and Green Street Green (1 mile north-east). A short drive away, we cover London (14 miles north-west), Shoreditch (15 miles north-west), Hoxton (15 miles north-west), Whitechapel (14 miles north-west), Brompton (15 miles north-west) and Stockwell (13 miles north-west).
Near you in Hazelwood
Locally, jobs take us to sites close to George and Dragon pub and Green Street Green Primary School. The closest station to Hazelwood is Chelsfield station, roughly 2.1 miles north-east of the centre. Well-known places in the area include Crofton Roman Villa (2.7 miles north) and Orpington Hospital (2.1 miles north-east). Not far away are Betsom's Hill and Downe Bank Nature Reserve.
What we’re called out for in Hazelwood
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.
Look out for the following:
- Damp inside where a wall movement joint has failed
- Water dripping through deck or ramp joints
- Joints where the bead has lost adhesion
- Spalled or broken joint edges in floors and decks
Another example is Biggin Hill Airport Trading Estate, 2.1 miles south-west of Hazelwood, where floors and yards would be done in stages around the occupiers.
Questions to ask before you book
- Will CSCS-carded applicators be on site?
- Will failed sealant be removed rather than covered?
- How long is the guarantee, and what does it include?
- The named product and why it was chosen
How the quote is worked out
To price the job, we consider:
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
- How much there is to seal
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- The postcode of the building
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email us to discuss it first.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Redoing a failed joint typically 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.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Damaged metal nosings or cover plates over a joint
- Cracking or settlement that calls for an engineer’s assessment
- Joints too narrow for the movement, which need redesigning by the engineer
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.

Your questions answered
Is Glebe Farm Business Park, near Hazelwood, within your area?
Yes, sites like Glebe Farm Business Park are within our area, along with the rest of Hazelwood. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
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
Do the joint edges need to be sound before sealing?
Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first, so the new seal has something to grip.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What happens if old sealant might contain asbestos?
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. Removing asbestos is a job for asbestos specialists, not us.

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Planning a London job such as one in Hazelwood starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Make sure the joints can be reached
- Let building users know which areas are affected
- Share the asbestos register for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Why act early in Hazelwood
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
