Facade sealing in Pitshanger, done properly

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. We work on cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are weathered facade joints that have lost their grip and leaks at window and door perimeters. A single leaking joint is often how a building in Pitshanger first comes to us: we look at the rest while we are there and tell you what we find.

Around Pitshanger, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, 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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Surface by surface

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch without tearing.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Planning a London job such as one in Pitshanger starts with access. Send the building rules and access times with your enquiry.

  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. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

Advice

Owners, agents and contractors

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Pitshanger. Several sites can go on one quote, so there’s one set of paperwork to deal with.

FAQs: Pitshanger

Would you work within a site like Cygnet Hospital Ealing?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work around term dates at a campus such as University of West London?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can staff carry on working while you’re here?

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

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Maintenance after handover

After handover, these steps help:

  • Keep the sealant details on the building file
  • Inspect facade joints on a regular cycle
  • Clear debris that holds water against joints
  • Share access with other external trades

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Facade sealing in Pitshanger: the local picture

Pitshanger has a good number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Site traffic in Pitshanger falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.

University estates such as University of West London, 1 mile south of Pitshanger, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Hotel extensions and refits, at places such as The Drayton Court Hotel, which lies south of Pitshanger, normally run between busy periods, so the sealing is squeezed into short windows. Hospital estates such as Cygnet Hospital Ealing (to the south-east of Pitshanger) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Pitshanger is about 1 mile north of Ealing, in Greater London. Commercial clients in Pitshanger use us for work on facade joints. Pitshanger is one of 764 places in Greater London on our list for facade joints. We also cover London, around 10 miles from Pitshanger.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first
  • How much there is to seal
  • Joint width, depth and condition

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • How the joints are reached, and at what height
  • Your programme or deadline
