Need facade sealing in Whyteleafe?

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

Your questions answered

Can you take on a job at a hospital such as North Downs Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is a smaller place like Whyteleafe outside your area?

No. Places such as Whyteleafe are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Do you run new sealant over the existing bead?

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

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

Facade sealing in Whyteleafe

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. If you’re dealing with draughts around frames and panels and water coming in around window frames, we can put it right, whatever the surface. Searching for sealant specialists in Whyteleafe? We’ve been sealing commercial buildings since 2005.

Around smaller places like Whyteleafe, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Share access with other external trades
  • Clear debris that holds water against joints
  • Keep the sealant details on the building file
  • Confirm the survey covers external sealants in older buildings

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Do you need facade sealing in Whyteleafe?

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and rips when the facade moves.

Most enquiries start with something like this:

  • Facade joints cracked through the middle
  • Air leaks through failed facade joints
  • Failed seals around shopfront and entrance frames
  • Weathered facade joints that have lost their grip

Older buildings in the area around Whyteleafe, such as Addington Palace, which lies north-east of Whyteleafe, need care when sealed: the product has to suit soft or historic materials.

What your quote should include

  • Health and safety accreditation such as CHAS
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will CSCS-carded applicators be on site?
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

How the job changes by surface

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

Precast concrete panels

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

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Whyteleafe can form part of a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Why act early in Whyteleafe

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice. One visit to deal with every failing joint makes more sense than several trips to a place like Whyteleafe. Photos of every joint help us quote for the whole job.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Sites and facades in and around Whyteleafe

Whyteleafe is about 13 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Whyteleafe included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

When a college such as Coulsdon Sixth Form College, 1.8 miles to the west of Whyteleafe, builds or refurbishes, the mastic package usually has to fit around students and staff. Units on estates such as Church Walk Shopping Centre, 1.8 miles south of Whyteleafe, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Whyteleafe is about 1 mile north of Caterham, in Surrey. If you are looking for facade sealing in Whyteleafe, we can help, as we do across Surrey. Our Surrey coverage takes in 379 places, from busy centres to rural villages. London is covered too, some 13 miles away.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Whyteleafe are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  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.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected
  • Send any specification or drawings in advance
