About our facade sealing in Yeading

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. The enquiries we see most involve air leaks through failed facade joints and failed sealant on precast panel joints, on cladding panel joints, window and door perimeters and coping and flashing joints. Whoever orders the work in Yeading, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

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.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What the job involves on each surface

Precast concrete panels

Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod.

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 as the frame moves.

Quoting for work in Yeading

The price varies from site to site. Expect it to depend on:

  • Distance, for remote addresses
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Joint width, depth and condition

Access can matter as much as the joints themselves: 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

Diagnosis starts before we arrive. Tell us:

  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available
  • The site address and postcode
  • Clear photos of the problem areas

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or use the quote form.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Specialist high-level access methods
  • Water getting in through cracked render or porous masonry
  • Installing or repairing glazing systems

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Joints and surfaces we work on

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

New build and refits around Yeading

Site traffic in Yeading falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. A number of hotels sit less than 2 miles from Yeading. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

For a contractor working at a hospital such as Ealing Hospital, 2.5 miles south-east of Yeading, perimeter and facade sealing is planned around patients and deliveries. School extensions, at buildings such as Brookside Primary School, usually run to the summer holidays, mastic included.

Yeading is about 2 miles north-east of Hayes, in Greater London. Yeading sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 764 places across Greater London fall within our area, Yeading among them. Sites around London have their own page, about 13 miles away.

Work on facade joints is covered throughout UB5, UB4 and UB1. Buildings on Owen Road, Friar Road and Maple Road are within our area for facade joints. Just outside Yeading, we also work in Yiewsley (1 mile north), Dormers Wells (2 miles south-east), Northolt (2 miles north-east), Southall (2 miles south) and South Ruislip (2 miles north). Further afield, our area takes in London (13 miles east), City of Westminster (10 miles east), Marylebone (11 miles east), Kensington (8 miles east), St Pancras (12 miles east) and Shoreditch (13 miles east).

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. For a job in Yeading, access comes first. Send the building rules and access times with your enquiry.

  1. Access, site rules and timing are settled with the client up front.
  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. Faces are cleaned, primed where needed and backed.
  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.

What we need from you

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

Your questions answered

Is hospital work, at somewhere like Ealing Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Can you find out why a window is leaking?

Yes. Photos help, and you can call 01277 525 020 or send details through our quote form to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will tell you which.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically 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 will set out a timescale with the quote.

When to call us in Yeading

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

Look out for the following:

  • Previous reseals run over old sealant
  • Weathered joints at frame-to-structure perimeters
  • Draughts around frames and panels
  • Discoloured or dirty facade joints

Building work at universities like Brunel University of London, 3.5 miles west of Yeading, is often timed for the summer, mastic included.

What to look for in a quote

  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Brief window cleaners about newly sealed joints
  • Walk the elevations once or twice a year
  • Plan facade sealing alongside redecoration
  • Don’t wait for a second leak before calling

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
