Expansion joint sealing for Dancers Hill sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Distance, for remote addresses
- Phasing around occupants
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- Where the site is, with the postcode
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older

Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Dancers Hill, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- 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 flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- 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.
Getting the site ready
- Tell us which areas need to stay in use
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space

Building owners, agents and FMs in Dancers Hill
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Joints too narrow for the movement, which need redesigning by the engineer
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.
What we seal
- Brickwork movement joints
- Podiums and floor movement joints
- Precast concrete panel joints
- Cladding panel joints
- Blockwork control joints
- Car park decks and ramps
What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we’ll plan around it. Around Dancers Hill, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
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.
What you get with us
- Joints cleaned back to sound surfaces
- RAL and finish matching where the product range allows
- CHAS accredited
- Over 20 years of commercial sealing

Different surfaces, different methods
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond, so the new seal holds.
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, normally low-modulus, with backing rod setting the depth.
Dancers Hill: questions and answers
Is Wrotham Business Park, near Dancers Hill, within your area?
Yes, sites like Wrotham Business Park are within our area, along with the rest of Dancers Hill. To start, just give us a call on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Do you take on work at healthcare sites like Potters Bar Community Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
What’s the difference between an expansion joint and a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint, and either way it needs a sound seal.
Is movement joint sealing guaranteed?
Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
What sealant do you use in movement joints?
Movement capability matters most. Hybrid or MS polymer products suit some mixed-material joints.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting, rather than replacing like for like.
Where floor joints take the most wear near Dancers Hill
Dancers Hill lies roughly 14 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Dancers Hill is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.
For a school such as Dame Alice Owen's School, playground and building joints can be done in the holidays.

Retail centres such as Spires Shopping Centre (1.8 miles south of Dancers Hill) have floors, service yards and car parks with joints under constant traffic.
