Facade sealing in Shortlands

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle facade sealing in Shortlands

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. We work on window and door perimeters, perimeter joints where frames meet the structure and cladding panel joints, and the failures we’re asked to look at most are draughts around frames and panels and failed seals around shopfront and entrance frames. Facilities teams, main contractors and managing agents in Shortlands tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Every London site, Shortlands 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

We work for building owners and managing agents on everything from one building to a spread of sites around Shortlands. One quote can cover more than one site, which keeps the paperwork simple.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Providing access systems for the work
  • Cracked or spalling substrates that need repair before sealing
  • Replacing glass or failed glazing units

If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer.

Surfaces we seal

  • Shopfront frames
  • Window and door perimeters
  • Stone and brick facade joints
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Cladding panel joints

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. 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.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements

Quoting for work in Shortlands

These are the things that shape the price:

  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Which sealant the job calls for
  • Whether the work must be split into stages

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email us.

Contractors’ notes for Shortlands

Shortlands has a number of hotels close by, all within 2 miles. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Shortlands. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

For a contractor at a hotel such as Royal Bell Hotel, 0.7 miles north-east of Shortlands, the mastic often has to be finished before a reopening date. New units and refits on sites such as Chartwell Business Centre (to the east of Shortlands) need their panel and perimeter joints sealed to the specification.

Shortlands is about 1 mile south-west of Bromley, in Greater London. Across the BR2 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Greater London, 764 places are covered, Shortlands among them. Sites around London have their own page, roughly 8 miles from Shortlands.

Work on facade joints is covered throughout BR2, BR1 and BR3. For a building on Hayes Lane, Stone Road and Hayes Road or nearby, send details and we’ll quote for facade joints.

FAQs: Shortlands

Would you work within a site like Sloane Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Chartwell Business Centre, near Shortlands?

Yes. Our area takes in Shortlands and its surroundings, with estates and business parks such as Chartwell Business Centre included. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do you use silicone for external joints?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Do we need an asbestos check before resealing?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

How much does the work cost?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

When to call us in Shortlands

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

It’s worth sending us details if you spot any of the following:

  • Staining on stone next to old sealant
  • Facade joints cracked through the middle
  • Draughts around frames and panels
  • Hard, chalky sealant that no longer flexes

Further education sites such as Bromley College (1.6 miles south-east of Shortlands) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants
  • Who will actually carry out the work
  • What level of public liability insurance do they hold?
