Facade sealing for Postling Green sites

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

Facade sealing for commercial buildings in Postling Green

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on stone and brick facade joints, perimeter joints where frames meet the structure and cladding panel joints, and the failures we are asked to look at most are facade joints cracked through the middle and weathered joints at frame-to-structure perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Postling Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Construction in and around smaller places such as Postling Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

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.

Questions about Postling Green

Is Postling Green too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you work on a hospital site such as William Harvey Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Will rain stop the work?

Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated throughout the job.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Contractors’ notes for Postling Green

Postling Green is about 54 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Postling Green sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

School extensions, at buildings such as Aldington Primary School, usually run to the summer holidays, mastic included. Historic houses such as Westenhanger Castle, 3.2 miles east of Postling Green, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Replacing glass or failed glazing units
  • Joints too narrow for the movement they take, which need redesign
  • Damaged frames that need replacing

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

Surfaces we seal

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

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Jobs in and around smaller places like Postling Green are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Share your working hours and any access restrictions
  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached

Why act early in Postling Green

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Older rural buildings around Postling Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Why appoint us

  • Workmanship guaranteed for 12 months
  • Standard and matched colours in many product ranges
  • Fully insured, including public liability cover
  • Old sealant cut out, never sealed over

How the job changes by surface

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.

Do you need facade sealing in Postling Green?

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.

Look out for the following:

  • Patch repairs that keep failing
  • Failed sealant on precast panel joints
  • Air leaks through failed facade joints
  • Perimeter joints where frames meet the structure

When units on a site such as Evegate Business Park, 2.2 miles north of Postling Green, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • How the joint faces will be prepared and primed
  • How they handle RAMS and site documents
  • Can the work be phased to keep areas open?
