Commercial sealant contractors in North Kensington
A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. We work on floor and threshold joints, movement joints in walls and floors and window and door perimeters, and what we are called in for most is greasy, split joints in a kitchen or tea point and window and door perimeter joints that have cracked open. Facilities teams, main contractors and managing agents in North Kensington tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In an occupied building in North Kensington, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.
Buildings in a London area such as North Kensington rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us, and where a brand finish matters, the sealant colour is agreed first.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Faulty windows rather than failed perimeter sealant
- Cracking that needs a structural engineer to look at it
- Water from a services leak rather than a joint
If you are not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer.

Commercial premises in North Kensington
Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We plan around them and agree phasing so tenants and clients aren’t disrupted. There are plenty of hotels within about 2 miles of North Kensington. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter; work is planned so the hotel keeps trading.
Refits at hotels like Samarkand Hotel, 0.9 miles south-east of North Kensington, bring joints at vanity tops, bars and reception desks that guests see every day. Shopping centres and retail parks such as Kensington Arcade (to the south-east of North Kensington) see a steady turnover of shop fits, each leaving joints where colour and finish matter. Shops and cafés around stations like Kensal Green station (0.5 miles north of North Kensington) trade from early, so work is timed around them.

Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
What we need from you

Your questions answered
Does a hotel in North Kensington need to shut while its sealant is renewed?
In most cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we will plan around them.
Can you work at a site such as Latimer Industrial Estate, by North Kensington?
Yes. Estates, retail parks and business parks around North Kensington, Latimer Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What about asbestos in old mastic?
Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Does commercial sealant work come with a guarantee?
Our workmanship is guaranteed for 12 months. We are fully insured for public liability as well.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
For managing agents and facilities managers
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Surface by surface
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.
Shop fronts and retail fit-outs
Retail work typically has to fit around trading. We plan around the access windows the store gives us, working in sections where that helps.
What affects the price in North Kensington
The price varies from site to site. Expect it to depend on:
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
- Distance, for remote addresses
- Any access equipment needed
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- What the building is and how it’s used
- Specification clauses that apply
- Access details, including height
- Drawings or a marked-up plan, if available
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
Maintenance after handover
After handover, these steps help:
- Make sure ventilation in wet areas is switched on and working
- Log reseals in the O&M or maintenance records
- Check sealant as part of routine building inspections
- Look at the sealant around anything that has been moved or replaced
Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks, especially on exposed elevations and in washrooms. If anything looks wrong, phone 01277 525 020 or send photos by email with a photo.
Sealant installed at the same time normally fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.
