Sealant specialists in Sidcup
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. Anything suspect is left alone until it has been tested. Site teams most often ask us about untidy joints in a reception, shop floor or lobby and hardened, chalky sealant on south-facing or exposed elevations, across washrooms and tea points, window and door perimeters and floor and threshold joints. One point of contact handles commercial sealant work in Sidcup from the first photos to the final walk-round, whether it’s one building or several.
In an occupied building in Sidcup, 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What we’re called out for in Sidcup
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into. Getting back to a clean joint then means removing every layer.
Site and facilities staff are often the first to spot these:
- A top-up bead over failed sealant, now lifting
- Leaks that seem to come through a sealant line
- Movement joints packed with grit and debris
- Frame mastic that has hardened and come away from the wall
If you run an office at a site such as Green Lane Business Park, which lies west of Sidcup, the sealant at reception desks, tea points and frames ages with each fit-out.

What Sidcup’s businesses ask us to seal
The 3 miles around Sidcup take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. The 2 miles around Sidcup include 15 care or nursing homes. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean, often in colours that suit the décor.
Sidcup 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. In a retail centre such as Broadway Shopping Centre, which lies north-east of Sidcup, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- A failed roof covering or waterproofing membrane
- Leaks from pipework, wastes or valves (that’s plumbing)
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.
What we seal
- Floor and threshold joints
- Kitchen worktops and splashbacks

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. All of Greater London is in the ULEZ, and kerbside space in Sidcup can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First, details reach us through the quote form or 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.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
Preparing the site
- Tell staff and tenants when we’ll be in
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Advice
Questions we are asked in Sidcup
Do hotels near Sidcup have to close for sealant work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Do you check for asbestos before removing sealant?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
What the job involves on each surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in.
Facade and cladding joints
Facade joints move every day as panels warm and cool. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
