Photos, a specification or a quick description of the joints is enough to start a fixed quote.
On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work 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. Planning a London job such as one in Mill Hill starts with access. Send the building rules and access times with your enquiry.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Getting the site ready

Advice
How we handle expansion joint sealing in Mill Hill
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. If you are dealing with rain penetration at brick or block movement joints and spalled or broken joint edges in floors and decks, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Mill Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Mill Hill, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What sets the cost
Before we quote, we look at:
- Working within restricted access windows
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
- Which sealant the job calls for
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- Clear photos of the problem areas
- Where the site is, with the postcode
- Whether an asbestos survey exists
- Anything awkward about access or site hours
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Traffic, movement and joints around Mill Hill
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. The 3 miles around Mill Hill take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
For estates staff at a university like Middlesex University, 1.7 miles to the south of Mill Hill, building and paving joints are part of the planned maintenance list.

Different surfaces, different methods
Podium joints
Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.
Cladding panel joints
We confirm what access is in place before pricing. Close-up photos help us judge the joints, or we visit if they don’t show enough.
After the work
For the best life from the joints:
- Avoid parking heavy plant or pallets on joint lines
- Brief car park operatives to protect joint lines during winter clearance
- Keep product details with the building records for the next reseal
- Include every elevation and deck joint in periodic inspections
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We’ll tell you which movement joints need doing now and which can wait.
Your questions answered
Can you cope with the access rules in a London building?
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 will plan accordingly. We allow for the ULEZ, which covers every borough
Does your area include sites such as Mill Hill Industrial Estate, near Mill Hill?
Yes. Our area takes in Mill Hill and its surroundings, with estates and business parks such as Mill Hill Industrial Estate included. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Which product is best for expansion joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Can you seal car park deck joints?
Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
