When to call us in River
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Things that typically lead to an enquiry:
- Damp inside where a wall movement joint has failed
- Joints packed with grit and debris
- Car park joints leaking onto vehicles below
- Sealant peeling off one face of the joint
Another example is Colhook Industrial Park., 2.5 miles to the north-east of River, where floors and yards would be done in stages around the occupiers.
Questions to ask before you book
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their public liability cover
Expansion joint sealing for commercial buildings in River
We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. Most enquiries involve sealant peeling off one face of the joint and water dripping through deck or ramp joints, across podiums and floor movement joints, brickwork movement joints and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in River it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Jobs around smaller places like River are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Where floor joints take the most wear near River
River sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. At about 42 miles from central London, River is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.
For an estate such as Midhurst Community Hospital, 3.2 miles to the west of River, the joints in ramps, decks and long building elevations all need attention over time. If you manage units on an estate such as Hampers Common Industrial Estate, which lies east of River, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.
River is about 12 miles east of Petersfield, in West Sussex. Anywhere in GU28, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. River is one of 373 places in West Sussex on our list. There’s a separate page for Portsmouth, about 22 miles away.

Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near River need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you
- Move anything stored against the joints
- Warn occupants and staff about the work
- Send any specification or drawings in advance
Ask for a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or use the quote form with what you know.

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Changing the joint layout or spacing of a structure
- Proprietary pre-formed expansion joint systems
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

River: questions and answers
Is River off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is a hospital such as Midhurst Community Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How long will the joint resealing take?
Expect anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Cure time before reopening is confirmed on the day.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you guarantee expansion joint work?
The workmanship is guaranteed for 12 months from sign-off. Keeping joints clear of debris helps them last.
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.
Maintenance after handover
Once the work is signed off, these steps help:
- Raise snow-clearing blades over deck joints where possible
- Keep product details with the building records for the next reseal
- Look over external and deck joints after a hard winter
- Clear dirt from joint lines during routine cleaning
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it. A routine sweep is the simplest protection.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Catching it early keeps the water outside.
What the job involves on each surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
