Facade sealing in Dial Post

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

Facade sealing in Dial Post

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. We work on stone and brick facade joints, window and door perimeters and shopfront frames, and the usual reasons a site gets in touch are failed seals around shopfront and entrance frames and facade joints cracked through the middle. A single leaking joint is often how a building in Dial Post first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Dial Post, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself
  • Specialist high-level access methods

If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

On site: what to expect

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 reopened once the sealant allows before the next one starts. Smaller jobs around Dial Post can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close
  • Tell staff and tenants when we will be in

Advice

When to call us in Dial Post

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.

It’s worth sending us details if you spot any of the following:

  • Old perimeter mastic that has dried out
  • Weathered joints at frame-to-structure perimeters
  • Cladding panel joints that have opened up
  • Facade joints cracked through the middle

On any site in or around Dial Post, the mastic follows the specification and the programme.

Comparing quotes

  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

What the job involves on each surface

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints, not the framing or glazing itself.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Dial Post: questions and answers

Is a smaller place like Dial Post outside your area?

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

Is Pondtail Farm (Business Park), near Dial Post, within your area?

Yes. Estates, retail parks and business parks around Dial Post, Pondtail Farm (Business Park) among them, are all within reach. Photos and a short description are enough for a first look.

How is access to upper-level joints handled?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Mastic packages on Dial Post sites

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, which is why external dates are agreed with the site manager. At about 39 miles from central London, Dial Post 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.

For contractors refurbishing units at places like Pondtail Farm (Business Park), which lies north of Dial Post, the mastic covers cladding panels, roller-door and window perimeters.

Why it’s worth doing now in Dial Post

Topping up a failed joint usually buys very little time. A full cut-out and reseal costs more on the day but lasts much longer. Older rural buildings around Dial Post 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.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why appoint us

  • 12 months’ guarantee on every job
  • A Constructionline member, so easy to vet
  • Coloured sealants to suit the setting, where available
  • CHAS accredited contractor

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. 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.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
