Facade sealing near Kenley

Facade sealing in Kenley

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about perimeter joints where frames meet the structure and failed sealant on precast panel joints, on cladding panel joints, coping and flashing joints and window and door perimeters. Facilities teams, main contractors and managing agents in Kenley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around Kenley, 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How the job changes by surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported first.

Why deal with it now?

Topping up a failed joint normally buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why us?

  • Failed material removed, not covered up
  • Fixed quotes based on photographs, drawings or a visit
  • Specification-led, product-correct work
  • Workmanship guaranteed for 12 months

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Clear debris that holds water against joints
  • Report water ingress at frames as soon as it shows
  • Avoid patch repairs on failed facade joints
  • Brief window cleaners about newly sealed joints

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

How the quote is worked out

What shapes the price:

  • The product specified
  • Whether old sealant has to be cut out first
  • Access and working height
  • Distance, for remote addresses

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

Good information means a firmer quote. Helpful details to send:

  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

New build and refits around Kenley

Site traffic in Kenley 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. The area within 2 miles of Kenley holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

New units and refits on sites such as Ullswater Industrial Estate, 1.6 miles west of Kenley, need their panel and perimeter joints sealed to the specification. With historic properties like Addington Palace, 3.3 miles north-east of Kenley, in the area, refurbishment work often meets old masonry that needs compatible sealants. When a college such as Purley Language College (to the north-west of Kenley) builds or refurbishes, the mastic package normally has to fit around students and staff.

Kenley is about 1 mile south-east of Purley, in Greater London. Businesses, contractors and managing agents in Kenley can call on us for facade joints. 764 places across Greater London fall within our area, including Kenley. Our London page has more on work in that area.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a job in Kenley, access comes first. Give us the hours we can be on site and we will schedule to suit.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements

Questions about Kenley

Can you take on a job at a hospital such as Purley War Memorial Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Could you schedule work at a campus like Purley Language College for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Do you replace failed glazing units?

No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.

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.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
