Expansion joint sealing for businesses in Keymer
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Why deal with it now?
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. Full removal and preparation is in every quote. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
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.
Why appoint us
- Fully insured, including public liability cover
- CSCS-carded applicators

Expansion joint sealing for commercial buildings in Keymer
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing. The enquiries we see most involve leaks through car park deck joints onto the level below and torn sealant in brick or block movement joints, on precast concrete panel joints, blockwork control joints and car park decks and ramps. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Keymer it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Work in a smaller place like Keymer is normally one building at a time, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
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.

What else we do in Keymer
Joints that move: notes for Keymer
At about 40 miles from central London, Keymer is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Keymer 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, while winter salting gets into any joint left open.
Parks like Victoria Business Park (to the north of Keymer) combine paved areas, car parks and building elevations, each with joints that move. In a school such as The Windmills Junior School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Keymer is about 2 miles south of Burgess Hill, in West Sussex. We cover Keymer and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 373 places in West Sussex. Brighton is covered too, around 6 miles from Keymer.

Surface by surface
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.
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

FAQs: Keymer
Do you cover business parks and estates near Keymer, such as Victoria Business Park?
Yes. Our area takes in Keymer and its surroundings, with estates and business parks such as Victoria Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Do you take on work at healthcare sites like The Dene Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Why has the sealant in our expansion joints split?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing, rather than replacing like for like.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How do I request a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Building owners, agents and FMs in Keymer
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Keymer can form part of a wider programme across West Sussex.
When to call us in Keymer
Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises. The product has to be suited to the traffic.
Clients normally get in touch after noticing something like this:
- Damp inside where a wall movement joint has failed
- Movement joints with split or torn sealant
- Joints where the bead has lost adhesion
- Expansion joints filled with dirt and stones
