Facade sealing for Shepherd's Bush sites

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

Common questions from Shepherd's Bush clients

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Can you work at a site such as Berghem Mews Business Village, by Shepherd's Bush?

Yes. Estates, retail parks and business parks around Shepherd's Bush, Berghem Mews Business Village among them, are all within reach. A few photographs and the unit address let us price the work.

Do you use silicone for external joints?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can you work while the building is occupied?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How we handle facade sealing in Shepherd's Bush

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. If you have perimeter joints where frames meet the structure and discoloured or dirty facade joints, we can help. For commercial sealant work in Shepherd's Bush, you deal with one contact from quote to sign-off, whether it’s one building or several.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email the details over and we’ll arrange a return visit.

Leave it or put it right?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Commercial clients in Shepherd's Bush

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

How the job changes by surface

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Facade sealing around Shepherd's Bush: what changes locally

There are a good number of hotels within about 2 miles of Shepherd's Bush. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Site traffic in Shepherd's Bush falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

Units on estates such as Berghem Mews Business Village (to the south of Shepherd's Bush) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For contractors at a college like St Charles Catholic Sixth Form College (1.1 miles north of Shepherd's Bush), perimeters and internal sealant are timed for the holidays. Building work at universities like BPP University (less than half a mile north-west of Shepherd's Bush) is often timed for the summer, mastic included.

Shepherd's Bush is about 1 mile west of Kensington, in Greater London. We cover Shepherd's Bush and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Across Greater London, 764 places are covered, Shepherd's Bush among them.

If you need facade sealing in W12, W11 and W14, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include Bard Road, Stowe Road and Wells Road. You will find Shepherd's Bush on or near the A402, so getting applicators and materials to site is simple. Nearby places we also cover include White City (1 mile north), Holland Park (1 mile east), Notting Hill (1 mile north-east), Kensington (1 mile east) and Notting Dale (1 mile north-east). A short drive away, we cover London (5 miles east), City of Westminster (3 miles east), Marylebone (3 miles east), St Pancras (5 miles east), Shoreditch (6 miles east) and Walthamstow (10 miles north-east).

Diagnose, treat, sign off

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a job in Shepherd's Bush, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements
  • Share your working hours and any access restrictions

After the work

For the best life from the joints:

  • Keep pressure washers away from fresh sealant
  • Insist on a full cut-out when joints are renewed
  • Note when each elevation was last resealed
  • Don’t wait for a second leak before calling

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, so brief your window cleaners.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
