Facade sealing in Hall's Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. 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.

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.

How we handle facade sealing in Hall's Green

Most facade joint failures trace back to the joint, not just the sealant. 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. We work on cladding panel joints, window and door perimeters and coping and flashing joints, and what we are called in for most is staining on stone next to old sealant and failed sealant on precast panel joints. A specialist sealant contractor works differently from a general builder: in Hall's Green, that means joint design, primers and backing rod as standard.

Construction in and around smaller places such as Hall's Green is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

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.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Hall's Green, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  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.

Before we start on site

  • Let us know about inductions and permits
  • Share the asbestos register for older buildings
  • Point out any areas we must not close

Questions about Hall's Green

Will you plan work around the academic year at somewhere like University of Kent - Tonbridge?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Would you work within a site like Hollanden Park 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.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do you work in Hall's Green?

Yes. Sites across Hall's Green are covered.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

What happens if it’s left?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Older rural buildings around Hall's Green move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • 12 months’ guarantee on every job
  • Fully insured, including public liability cover

How the job changes by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Movement beyond what any sealant can handle
  • Installing or repairing glazing systems
  • Damaged frames that need replacing

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Facades, frames and programmes in Hall's Green

Hall's Green is in the South East, one of the UK’s drier regions.
