Expansion joint sealing for commercial buildings in Pratt's Bottom
Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. If you have sealant peeling off one face of the joint and layers of sealant in a movement joint, we can help. Most enquiries from Pratt's Bottom start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Areas such as a loading bay or car park deck in Pratt's Bottom typically have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we’ll arrange a return visit.

General trades versus a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep traffic off new joints until the cure time is up
- Keep scrapers and ploughs from dragging across joint sealant
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Inspect movement joints alongside other routine building checks
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.
From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a job in Pratt's Bottom, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- 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.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Confirm the product named in the specification
- Share the asbestos register for older buildings

Questions we’re asked in Pratt's Bottom
Is hospital work, at somewhere like Chelsfield Park Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you take on jobs in Pratt's Bottom where loading and access are tightly controlled?
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’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you offer coloured sealant?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.
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.

Why act early in Pratt's Bottom
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. We cut out the old seal and prepare the faces every time. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
