Facade sealing near Bromley
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Different surfaces, different methods
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
How we handle facade sealing in Bromley
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. If you have failed seals around shopfront and entrance frames and staining on stone next to old sealant, we can put it right. For commercial sealant work in Bromley, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Construction in a London area such as Bromley means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
How a job runs
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 the sealant is tooled off neatly. Planning a London job such as one in Bromley starts with access. Send the building rules and access times with your enquiry.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open
- Have the specification and drawings to hand

Advice
Contractors’ notes for Bromley
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Bromley. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. The area within 2 miles of Bromley holds several hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
When a college such as Bromley College (1.4 miles south-east of Bromley) builds or refurbishes, the mastic package typically has to fit around students and staff. New wings at hospitals like Sloane Hospital, 0.9 miles to the north-west of Bromley, bring long runs of window and panel joints to seal.
Bromley is about 8 miles south-east of London, in Greater London. Bromley sits inside our coverage and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Our Greater London coverage takes in 764 places, from busy centres to rural villages. There’s a separate page for London, about 8 miles away.
Work on facade joints is covered throughout BR2, BR1, BR6 and BR5. Buildings on High Street, Church Road and St Paul's Square are within our area for facade joints. Main routes into Bromley include the A222 and A223, which helps when planning parking and deliveries for the job. Sites close to Bromley are covered too, including Sundridge (1 mile north-east), Plaistow (1 mile north), Bickley (1 mile east), Widmore (1 mile east) and Downham (2 miles north). Nearby towns on our patch include London (8 miles north-west), City of Westminster (11 miles north-west), Marylebone (11 miles north-west), Kensington (12 miles north-west), St Pancras (10 miles north-west) and Shoreditch (9 miles north-west).
Landmarks near Bromley
Locally, jobs take us to sites close to Bullers Wood School for Boys, The Richmal Crompton pub and Church House Gardens and the streets around them. Bromley has its own railway station: Bromley South station. Nearby you will also find The Mall (less than half a mile east) and Bromley Hospital (under half a mile south-east). The countryside around Bromley includes Downham Woodland Walk and Summer Hill.
Why deal with it now?
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What else we do in Bromley
Common questions from Bromley clients
Is hospital work, at somewhere like Sloane Hospital, something you do?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you take on jobs in Bromley where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Damaged frames that need replacing
- Providing access systems for the work
- Joints too narrow for the movement they take, which need redesign
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly.
Joints and surfaces we work on
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Coping and flashing joints
- Stone and brick facade joints
- Cladding panel joints
- Shopfront frames
When to call us in Bromley
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.
Typical triggers for a call:
- Leaks at window and door perimeters
- Weathered facade joints that have lost their grip
- Weathered joints at frame-to-structure perimeters
- Previous reseals run over old sealant
Hotels like Royal Bell Hotel, less than half a mile north of Bromley, rarely close for long, so refurbishment mastic is phased floor by floor.
