Facade sealing for Steeple Barton sites

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

What sets the cost

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

  • Site requirements such as inductions and permits
  • The product specified
  • How accessible the joints are
  • Phasing around occupants

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • What the building is and how it’s used
  • The asbestos register, for older buildings
  • The site address and postcode
  • The product your specification calls for

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email drawings and photos.

About our facade sealing in Steeple Barton

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. Most enquiries involve failed seals around shopfront and entrance frames and weathered facade joints that have lost their grip, on stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters. Whoever orders the work in Steeple Barton, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Sites around smaller places like Steeple Barton can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we’ll quote to suit.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. If others near Steeple Barton need work, visits can be combined. You’ll have a fixed quote before work starts.

  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. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use

Advice

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Joints whose design needs changing by the specifier
  • Render or concrete edges that have broken away
  • Replacing glass or failed glazing units

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Surfaces we seal

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

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Steeple Barton: questions and answers

Does your area include sites such as Hatch End Old Industrial Estate, near Steeple Barton?

Yes. We cover Steeple Barton and the area around it, including industrial estates, business parks and retail parks such as Hatch End Old Industrial Estate. A few photos and the unit address let us price the work.

Can you keep pace with our programme in Steeple Barton?

Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What do you charge?

We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.

Which sealant do you use on facades?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

Mastic packages on Steeple Barton sites

At about 61 miles from central London, Steeple Barton is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Steeple Barton is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

Signs you need facade sealing in Steeple Barton

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.

What tends to prompt an enquiry:

  • Old perimeter mastic that has dried out
  • Water coming in around window frames
  • Previous reseals run over old sealant
  • Air leaks through failed facade joints

Units on estates such as Hatch End Old Industrial Estate, 1.7 miles to the north-east of Steeple Barton, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Comparing quotes

  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?
  • What site paperwork they can supply
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

General trades versus a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
