About our facade sealing in Tulse Hill

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on cladding panel joints, stone and brick facade joints and window and door perimeters, and the usual reasons a site gets in touch are patch repairs that keep failing and perimeter joints where frames meet the structure. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Tulse Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Construction in a London area such as Tulse Hill means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.

Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or use the quote form and we will arrange a return visit.

Surface by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

FAQs: Tulse Hill

Can work at a site such as King's College London fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work in a London building with booked loading and goods-lift slots?

Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

Do you seal facades in winter?

Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Can you find out why a window is leaking?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Can you fit around our working hours?

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

Maintenance after handover

For the best life from the joints:

  • Check that rainwater leaves the facade the way it was designed to
  • Inspect facade joints on a regular cycle
  • Insist on a full cut-out when joints are renewed
  • Avoid harsh cleaners on facade sealant

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade rather than sitting against the joints.

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.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Travel to remote or island sites
  • The site’s rules and procedures
  • The total length or number of joints
  • Phasing around occupants

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • The asbestos register, for older buildings
  • The site address and postcode
  • Photos of the joints, close up and from further back
  • Access details, including height

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Getting scaffold, permits or access booked in Tulse Hill takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why us?

  • Specification-led, product-correct work
  • RAL and finish matching where the product range allows
  • One contact handling all your sites
  • CHAS accredited contractor

Facade sealing around Tulse Hill: points for this area

A 2-mile radius around Tulse Hill takes in plenty of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Site traffic in Tulse Hill 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.

For contractors at a college like William Booth College, 1.8 miles to the north-east of Tulse Hill, perimeters and internal sealant are timed for the holidays. Hotel extensions and refits, at places such as Leigham Court Hotel, which lies south-west of Tulse Hill, normally run between busy periods, so the sealing is squeezed into short windows. Units on estates such as Bessemer Park Industrial Estate (1 mile north of Tulse Hill) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Tulse Hill is about 1 mile north-east of Streatham, in Greater London. We cover commercial sites throughout Tulse Hill, for single jobs and planned programmes alike. 764 places across Greater London fall within our area, including Tulse Hill.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  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. 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.

Before we start on site
