When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. If you have frame sealant that has cracked, shrunk or pulled away and untidy joints in a reception, shop floor or lobby, we can put it right, on washrooms and tea points, floor and threshold joints and movement joints in walls and floors alike. A specialist sealant contractor works differently from a general builder: on jobs in Barnes, preparation and product choice get the time they need.
If you look after more than one building near Barnes, the work can be planned as one programme, with one quote format and one point of contact.
For managing agents and FMs looking after premises in Barnes, access is usually the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Common problems we fix in Barnes
The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.
If one of these sounds familiar, it’s time for a closer look:
- Sanitary sealant that has gone black and patchy
- Layers of sealant, all of them failing
- Smeared sealant across finishes from a rushed job
- Window and door perimeter joints that have cracked open
Barnes is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details.

What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- A dripping trap, valve or pipe behind a fitting
- Faulty windows rather than failed perimeter sealant
- Roof leaks that only look like a joint problem
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.
What we seal
- Kitchen worktops and splashbacks
- External facade joints
- Window and door perimeters
- Washrooms and tea points
- Floor and threshold joints
- Movement joints in walls and floors
Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. In Barnes, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Getting the site ready
- Flag any permit to work we will need
- Agree which areas must stay open
- Warn occupants and staff about the work
Getting a fixed quote

Advice
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Put external and wet-area joints on a regular inspection round
- Log reseals in the O&M or maintenance records
- Look at the sealant around anything that has been moved or replaced
- Make sure contractors see the asbestos survey before cutting out old mastic
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth, and we confirm it when each area is handed back. Leaving the area closed until then keeps the bead neat.
Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We can assess the lot and suggest what to do now and later.
What Barnes’s businesses ask us to seal
The 3 miles around Barnes take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal. In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We work within them, one zone at a time.
For a retailer at a site such as Kew Retail Park, which lies west of Barnes, the joints clients see are as much part of the fit-out as the shelving. A business with units at Kew Retail Park and Berghem Mews Business Village needn’t use two contractors for its sealant.
Barnes is about 2 miles west of Fulham, in Greater London. Barnes sits inside our coverage and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Greater London coverage takes in 764 places. Our London page has more on work in that area.
Business premises anywhere in SW13, SW15 and SW14 are within our area. For a building on Church Road, Station Road and Barnes High Street or nearby, send details and we will quote for sealant joints. Barnes sits on or close to the A306 and B349, useful when we plan access and materials. If your building is just outside Barnes, we cover Old Chiswick (1 mile north), Turnham Green (1 mile north-west), Mortlake (1 mile south-west), East Sheen (1 mile south-west) and Putney (1 mile south-east). Nearby towns on our patch include London (7 miles east), City of Westminster (5 miles north-east), Marylebone (5 miles north-east), Kensington (3 miles north-east), St Pancras (7 miles north-east) and Shoreditch (8 miles north-east).
Around Barnes
Locally, jobs take us to sites close to Chiswick School, Sun Inn and Barn Elms, among other places. Nearby too are Polish Library POSK in London (1.4 miles north) and The Harrodian School (0.6 miles north). There’s a railway station in Barnes itself: Barnes Bridge station. Nearby you’ll also find Barnes Hospital (0.7 miles south-west) and Putney Exchange (1.4 miles south-east). Green spaces nearby include Richmond Hill and Kew Gardens Lake.
Different surfaces, different methods
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
Window and door perimeters
The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.

Questions about Barnes
Does your area include sites such as Kew Retail Park, near Barnes?
Yes. We cover Barnes and the area around it, including industrial estates, business parks and retail parks such as Kew Retail Park. 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 you take on jobs in Barnes where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we’ll work to them.
Do you seal on top of existing 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.
Can you supply RAMS and insurance details?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you check for asbestos before removing sealant?
Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.
Can areas stay open during the work?
Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.
