Construction mastic near Bickley
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Work for main contractors and building owners
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Construction mastic for commercial buildings in Bickley
On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers on schemes in Bickley, sealing plot by plot or floor by floor as areas are released. We work on floor and skirting junctions, internal decorators’ caulk and sanitary and kitchen joints, and the failures we’re asked to look at most are frame perimeters left unsealed or poorly sealed and new external sealant already peeling away. Whoever orders the work in Bickley, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Every London site, Bickley included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
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 spell out the cover before we begin.

Mastic packages on Bickley sites
A 2-mile radius around Bickley takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Bickley. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For contractors on a campus like University of Greenwich - Avery Hill, 3.4 miles to the north of Bickley, facade and perimeter sealing has to fit around students and term dates. For a contractor working at a hospital such as Sloane Hospital, 2.3 miles to the west of Bickley, perimeter and facade sealing is planned around patients and deliveries. For a contractor at a hotel such as Bickley Manor Hotel and Restaurant (0.6 miles south-east of Bickley), the mastic often has to be finished before a reopening date.
Bickley is about 1 mile east of Bromley, in Greater London. We cover commercial sites throughout Bickley, whether it’s a single job or part of a planned programme. Across Greater London, 764 places are covered, Bickley among them. Sites around London have their own page, about 9 miles away.
Anyone looking for construction mastic in BR1, BR2 and BR7 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Golf Road, The Avenue and Canon Road are within our area for mastic packages. Nearby places we also cover include Widmore (1 mile north), Elmstead (1 mile north), Chislehurst (1 mile north-east), Bromley (1 mile west) and Sundridge (1 mile north-west) for mastic packages. Further afield, our area takes in London (9 miles north-west), City of Westminster (12 miles north-west), Marylebone (12 miles north-west), Kensington (13 miles north-west), St Pancras (11 miles north-west) and Shoreditch (10 miles north-west).
Landmarks near Bickley
Recent enquiries here include premises near Bird In Hand Public House, Holy Trinity College Bromley and Jubilee Country Park, among other places.

The countryside around Bickley includes Summer Hill and The Tarn.
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Get the mastic subcontractor involved early in the programme
- Brief following trades on areas that have been sealed
- Keep scrapers and abrasive pads off new beads
- Allow flexibility for external sealing in damp or cold weather
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover as agreed in the quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We flag them as soon as we see them.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
- Quantities, in metres or numbers
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
The more we know, the firmer the quote. Helpful details to send:
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
- The postcode of the building
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send photos by email.
What else we do in Bickley
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Common questions from Bickley clients
Is a hospital such as Sloane Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can work at a site such as University of Greenwich - Avery Hill fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Is colour matching possible?
That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Can you work while the building is occupied?
Normally, yes. We phase the work so most of the building stays in use.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Bickley can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in
- Send any specification or drawings in advance
- For older buildings, check the asbestos register before work
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Joints damaged after sign-off by following trades
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
