Facade sealing near Widmore
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Getting the site ready
- Make sure the joints can be reached
- Confirm the product named in the specification
- Let building users know which areas are affected

Facade sealing in Widmore, done properly
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on window and door perimeters, perimeter joints where frames meet the structure and coping and flashing joints, and the failures we’re asked to look at most are leaks at window and door perimeters and facade joints cracked through the middle. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Widmore, preparation and product choice get the time they need.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What happens if it’s left?
Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.

Widmore: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Can you work around term dates at a campus such as University of Greenwich - Avery Hill?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you just add new sealant on top?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Can you look at water coming in around a frame?
Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
How the quote is worked out
To price the job, we consider:
- Whether old sealant has to be cut out first
- How much there is to seal
- Any access equipment needed
- Working within restricted access windows
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Facade sealing around Widmore: how the place shapes the job
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Widmore. Deliveries are booked and storage is tight, so mastic materials come in as needed. Several hotels sit less than 2 miles from Widmore. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
University estates such as University of Greenwich - Avery Hill (to the north of Widmore) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. For contractors at a college like Bromley College, 1.1 miles south-west of Widmore, perimeters and internal sealant are timed for the holidays. Hotel extensions and refits, at places such as Bickley Manor Hotel and Restaurant, which lies south-east of Widmore, normally run between busy periods, so the sealing is squeezed into short windows.
Widmore is about 1 mile east of Bromley, in Greater London. Anywhere in BR1, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

When to bring in a specialist
Certain joints really need a specialist: 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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Surface by surface
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.
