Facade sealing for commercial buildings in White City
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Site teams most often ask us about air leaks through failed facade joints and damp patches beside frames after rain, on shopfront frames, coping and flashing joints and window and door perimeters. Facilities teams, main contractors and managing agents in White City tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around White City, as across London, much of the work is refurbishing existing buildings as well as building new ones. 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.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: White City
Can you work in a London building with booked loading and goods-lift slots?
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. All of Greater London is inside the ULEZ, and our planning allows for it
Can you take on a job at a hospital such as Hammersmith Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
What happens if it’s left?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Getting scaffold, permits or access booked in White City takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Do you need facade sealing in White City?
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.
It’s worth sending us details if you spot any of the following:
- Old perimeter mastic that has dried out
- Damp patches beside frames after rain
- Draughts around frames and panels
- Previous reseals run over old sealant
Projects at colleges like St Charles Catholic Sixth Form College (0.6 miles north-east of White City) tend to run to term dates, so the mastic is planned tightly.
What to look for in a quote
- Whether their applicators hold CSCS cards
- Do they follow the manufacturer’s priming guidance?
- Which product they’ll use, and why it suits the joint
- Will failed sealant be removed rather than covered?
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Don’t wait for a second leak before calling
- Check that rainwater leaves the facade the way it was designed to
- Avoid patch repairs on failed facade joints
- Walk the elevations once or twice a year
Following storms, look inside for damp or staining near frames. An early report normally means a small reseal rather than a bigger repair.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down and limits disruption.
Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in White City can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Send any specification or drawings in advance
- Share the asbestos register for older buildings
- Make sure the joints can be reached
