Commercial sealant contractors in St Ann's, done properly
On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. If you’re dealing with gaps behind commercial kitchen worktops and sinks and smeared sealant across finishes from a rushed job, we can help, whatever the surface. Facilities teams, main contractors and managing agents in St Ann's tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In an occupied building in St Ann's, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Questions about St Ann's
Is Crusader Industrial Park, near St Ann's, within your area?
Yes, sites like Crusader Industrial Park are within our area, along with the rest of St Ann's. Send details of the unit and the work through our quote form for a quick quote.
Do you take on jobs in St Ann's where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do we get a quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.
Does commercial sealant work come with a guarantee?
The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Common problems we fix in St Ann's
Washrooms and kitchens wear sealant out in their own way. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant, and once established it rarely cleans out. The fix is a new bead of anti-mould sanitary silicone.
Things that normally lead to an enquiry:
- Weathered facade sealant that no longer flexes
- Water staining near frames, panels or ceilings
- Greasy, split joints in a kitchen or tea point
- Messy, uneven beads from earlier work that let the building down
On estates like Crusader Industrial Park, under half a mile to the south-west of St Ann's, the office and welfare end of each unit has its own sealant to maintain.
What your quote should include
- Health and safety accreditation such as CHAS
- Do they follow the manufacturer’s priming guidance?
- Is the sealant right for the movement and the substrate?
- Whether their applicators hold CSCS cards
Looking after the joints
After handover, these steps help:
- Report cracked or peeling sealant early
- Put external and wet-area joints on a regular inspection round
- Check the asbestos register before anyone disturbs old sealant in an older building
- Keep washroom and kitchen extraction working
Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records.
Sealant installed at the same time normally fails in sequence. A few splits this year usually mean more next year, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Old mastic that tests positive for asbestos
- Broken glass or blown double-glazed units
If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Kitchen worktops and splashbacks
- Movement joints in walls and floors
- Washrooms and tea points
- Window and door perimeters
- Floor and threshold joints
- External facade joints
What affects the price in St Ann's
The price varies from site to site. It mainly depends on:
- The total length or number of joints
- Backing rod, priming and other preparation
- The site’s rules and procedures
- Access and working height
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Any specification or named product
- Approximate linear metres or a joint schedule
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, call the office on 01277 525 020 or email a schedule or drawings.

Other services in St Ann's
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in St Ann's can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- We hand back each area with its cure time and our 12-month guarantee.
Getting the site ready
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Move anything stored against the joints

Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We fit into those systems and phase the work so the building keeps operating. Less than 3 miles from St Ann's there are at least three named estates and business parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies.
Occupiers with premises at both Crusader Industrial Park and Arena Shopping Park could have the sealant at each handled under one quote. With St Ann's inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site.
