You can also call the office on 01277 525 020 or send photos by email to talk the joints through. Site teams most often ask us about expansion joints split through the centre of the bead and previous reseals laid over old sealant, on cladding panel joints, podiums and floor movement joints and blockwork control joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Heronden it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller community and commercial buildings around Heronden have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Joints that move: notes for Heronden
Heronden lies roughly 62 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Rainfall across the South East, Heronden included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.
On a site such as Birnham Farm Business Centre, 1.4 miles north of Heronden, the movement joints are in car park slabs, paving and building elevations. Another example is Pike Road Industrial Estate, 2.4 miles south of Heronden, where floors and yards would be done in stages around the occupiers. In a school such as Eastry Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Heronden is about 5 miles west of Deal, in Kent. If you are looking for expansion joint sealing in Heronden, we can help, as we do across Kent. Heronden is one of 931 places we cover in Kent. For work in that direction, see our London page (62 miles or so).

Your questions answered
Is Birnham Farm Business Centre, near Heronden, within your area?
Yes. We cover Heronden and the area around it, including industrial estates, business parks and retail parks such as Birnham Farm Business Centre. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do we have to stop operations in Heronden while the joints are sealed?
Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Why has the sealant in our expansion joints split?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first.
Can a joint be sealed if the edges are broken?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we will say so when we quote.
Surface by surface
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, typically low-modulus laid over backing rod at the correct depth.
Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Heronden, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- 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.
Getting the site ready
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Confirm the product named in the specification
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Record the sealant used and the date in the O&M file
- Check joints after long freezing spells
- Act on the first tear or lifting edge rather than waiting
- Keep racking legs and heavy point loads off floor joints
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, call the office on 01277 525 020 or send details through our quote form with photographs.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.
Why act early in Heronden
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly. Full removal and preparation is in every quote. One visit to deal with every failing joint makes more sense than several trips to a place like Heronden, rather than one at a time. Photos of every joint help us quote for the whole job.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
