Facade sealing for commercial buildings in Bexon

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. Most enquiries involve cladding panel joints that have opened up and perimeter joints where frames meet the structure, across stone and brick facade joints, coping and flashing joints and cladding panel joints. Facilities teams, main contractors and managing agents in Bexon tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Bexon bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Work on the window or framing system itself
  • Providing access systems for the work
  • Water getting in through cracked render or porous masonry

If you’re not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.

Where we work in Bexon

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

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Rural sites near Bexon may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification

Quoting for work in Bexon

Quotes vary with the job. Expect it to depend on:

  • Quantities, in metres or numbers
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation
  • The product specified

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

What to include in your enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • Specification clauses that apply
  • Where the site is, with the postcode
  • What the building is and how it’s used
  • Clear photographs of the problem areas

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Sites and facades in and around Bexon

The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Bexon is about 37 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

Building work at universities like Canterbury Christ Church University, 2.8 miles south-west of Bexon, is often timed for the summer, mastic included. Extensions at sites like Sittingbourne Memorial Hospital, 2.4 miles north-east of Bexon, typically sit beside working departments, and the mastic follows strict access rules.

Signs you need facade sealing in Bexon

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.

These are often picked up first by site or facilities staff:

  • Old perimeter mastic that has dried out
  • Staining on stone next to old sealant
  • Sealant pulling away from frames or panels
  • Patch repairs that keep failing

School extensions, at buildings such as Bredgar Church of England Primary School, normally run to the summer holidays, mastic included.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Whether their applicators hold CSCS cards
  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
