Facade sealing for commercial buildings in Ardingly

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, so the price covers the real job. Site teams most often ask us about patch repairs that keep failing and unsightly perimeter sealant on a visible elevation, across cladding panel joints, coping and flashing joints and shopfront frames. One point of contact handles commercial sealant work in Ardingly from the first photographs to the final walk-round, whether it’s one building or several.

Construction in and around smaller places such as Ardingly 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.

Every job we finish is backed by a 12-month workmanship guarantee, in Ardingly as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What we can’t put right

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:

  • Work on the window or framing system itself
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Movement beyond what any sealant can handle

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.

Surfaces we seal

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

Mastic packages on Ardingly sites

Ardingly 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, which is why external dates are agreed with the site manager. At about 31 miles from central London, Ardingly is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

With historic properties like Priest House (2.2 miles north-east of Ardingly) in the area, refurbishment work often meets old masonry that needs compatible sealants. When units on a site such as Horsted Keynes Business Park (2 miles east of Ardingly) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Ardingly is about 3 miles north of Haywards Heath, in West Sussex. Anywhere in RH17, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 373 places in West Sussex, large and small. There’s a separate page for Brighton, roughly 15 miles from Ardingly.

Business premises anywhere in RH17 are within our area for facade joints. Among the streets we cover are High Street, Munnion Road and Price Way. Sites close to Ardingly are covered too, including Little London (1 mile north), Highbrook (1 mile north-east), Lindfield (2 miles south), Horsted Keynes (2 miles east) and West Hoathly (2 miles north-east). Bigger towns within reach include Crawley (6 miles north-west), Horsham (10 miles west), Haywards Heath (3 miles south), Burgess Hill (7 miles south), East Grinstead (6 miles north-east) and Broadfield (6 miles north-west).

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Ardingly need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Let us know about inductions and permits
  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints

How the job changes by surface

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.

What we are called out for in Ardingly

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone, so the new bead peels away within a season or two.

What tends to prompt an enquiry:

  • Previous reseals run over old sealant
  • Air leaks through failed facade joints
  • Hard, chalky sealant that no longer flexes
  • Failed seals around shopfront and entrance frames

For contractors at a school such as St Peter's CofE Primary School, sealing has to be finished before term starts.

Choosing a commercial sealant contractor

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Walk the elevations once or twice a year
  • Report water ingress at frames as soon as it shows
  • Avoid patch repairs on failed facade joints
  • Record the product and colour used on each elevation

Record the sealant type and date on the building file. Future work can then match the product and colour.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.

Leave it or put it right?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Around Ardingly, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why us?

  • Joints cleaned back to sound surfaces
  • Over 20 years of commercial sealing
  • Colours chosen to suit frames, cladding or finishes where possible
  • Public liability insurance in place

Questions we are asked in Ardingly

Can work at a site such as Haywards Heath College fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Ardingly off your patch?

Not at all. Ardingly is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use.

How is access to upper-level joints handled?

We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
