Facade sealing for Brompton sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Facade sealing in Brompton, done properly
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. If you are dealing with perimeter sealant that has split or peeled away and previous reseals run over old sealant, we can put it right. A single leaking joint is often how a building in Brompton first comes to us: we look at the rest while we’re there and tell you what we find.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Contractors’ notes for Brompton
Brompton has plenty of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. As part of Greater London, Brompton is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
On a healthcare site such as The Royal Marsden Hospital, 0.5 miles south-west of Brompton, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Recladding or extending a unit at a site like Brompton Cross District Shopping Centre. (less than half a mile west of Brompton) brings panel joints and frame perimeters into the programme.
Brompton is about 1 mile south of City of Westminster, in Greater London. Businesses, contractors and managing agents in Brompton use us for work on facade joints, as part of our coverage of Greater London. Across Greater London, 764 places are covered, including Brompton.

Maintenance after handover
After handover, a little attention goes a long way:
- Avoid patch repairs on failed facade joints
- Don’t wait for a second leak before calling
- Combine resealing with other works that need access
- Ask about asbestos in pre-2000 mastic
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.
Questions about Brompton
Do you cover business parks and estates near Brompton, such as Brompton Cross District Shopping Centre.?
Yes. Estates, retail parks and business parks around Brompton, Brompton Cross District Shopping Centre. Among them, are all within reach. A few photographs and the unit address let us price the work.
Could you schedule work at a campus like Faculty of Medicine (Imperial College London) for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Should we check old sealant for asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
For managing agents and facilities managers
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Quoting for work in Brompton
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The total length or number of joints
- Whether the work must be split into stages
- How accessible the joints are
- Site requirements such as inductions and permits
What a job costs comes down to 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.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- How the joints are reached, and at what height
- When you need the work done
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or use the quote form.
Do you need facade sealing in Brompton?
When the sealant tears down its centre, it has typically been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
It’s worth sending us details if you spot any of the following:
- Leaks at window and door perimeters
- Failed sealant on precast panel joints
- Weathered facade joints that have lost their grip
- Discoloured or dirty facade joints
Work at a hotel such as The Beaufort Hotel (under half a mile north of Brompton) tends to be programmed around bookings, mastic included.
What your quote should include
- Their public liability cover
- What the guarantee covers, and for how long
- How they’ll work around occupants
- How joint depth will be controlled
What else we do in Brompton
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
