Commercial sealant contractors for commercial buildings in Cannon Hill
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). If you are dealing with movement joints packed with grit and debris and greasy, split joints in a kitchen or tea point, we can put it right. Most enquiries from Cannon Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Occupied buildings in Cannon Hill need the work phased: washrooms in turn, floors in sections and entrances kept open.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Do you need commercial sealant contractors in Cannon Hill?
If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
Things that usually lead to an enquiry:
- Earlier reseals applied straight onto the failed bead
- Smeared sealant across finishes from a rushed job
- Shrunken sealant along kitchen worktops and splashbacks
- Mouldy silicone around WCs, urinals and vanity tops
For premises near South Merton station, 0.5 miles to the north-east of Cannon Hill, footfall is part of the plan: work is phased so shops and offices keep trading.

Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Log reseals in the O&M or maintenance records
- Keep abrasive pads and scrapers off resealed joints
- Respect the cure time before reopening an area
- Check the asbestos register before anyone disturbs old sealant in an older building
In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. Your maintenance team can look at extract fans at the same time.
Sealant rarely fails all at once across a building. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We will tell you which sealant joints need doing first and which can wait.

Questions we’re asked in Cannon Hill
Is Rainbow Industrial Estate, near Cannon Hill, within your area?
Yes, sites like Rainbow Industrial Estate are within our area, along with the rest of Cannon Hill. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
Does a hotel in Cannon Hill need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.
Can you supply RAMS and insurance details?
We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes a few hours to several days on most single sites, depending on joint lengths and access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What sets the cost
These are the things that shape the price:
- Travel to remote or island sites
- Which sealant the job calls for
- Working within restricted access windows
- Any access equipment needed
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.
Details that help us quote
However big the job, these details speed things up:
- Any specification or named product
- A wide shot and a close-up of the area
- The postcode of the building
- Any dates the work must fit around
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or send photos by email.

Our process
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Point out any areas we must not close
- Arrange parking or a loading space
- Share the asbestos register for older buildings
Ask for a quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
Doing it in-house
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 easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
