Facade sealing in Arundel

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

Facade sealing for commercial buildings in Arundel

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, often at around 2:1 width to depth, as the manufacturer advises. Most enquiries involve old perimeter mastic that has dried out and draughts around frames and panels, on coping and flashing joints, stone and brick facade joints and window and door perimeters. Most enquiries from Arundel start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In a smaller place such as Arundel, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Our process

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. What matters most for a job in Arundel is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  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. We remove the old bead and check the edges are sound.
  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

  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.

Related advice

Do you need facade sealing in Arundel?

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.

Things that typically lead to an enquiry:

  • Gaps between rainscreen or cladding panels
  • Leaks at window and door perimeters
  • Air leaks through failed facade joints
  • Perimeter sealant that has split or peeled away

For a contractor at a hotel such as The Norfolk Hotel, which lies east of Arundel, the mastic often has to be finished before a reopening date.

Questions to ask before you book

  • How they’ll work around occupants
  • How joint depth will be controlled
  • Are they CHAS accredited or on Constructionline?
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

Surface by surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

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.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Check that rainwater leaves the facade the way it was designed to
  • Walk the elevations once or twice a year
  • Confirm the survey covers external sealants in older buildings
  • Note when each elevation was last resealed

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

Arundel: questions and answers

Is a hospital such as Arundel & District Community Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as The Vinery Industrial Estate, by Arundel?

Yes, sites like The Vinery Industrial Estate are within our area, along with the rest of Arundel. Photos and a short description are enough for a first look.

Will rain stop the work?

Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.

Can you just add new sealant on top?

No. New sealant won’t hold on old sealant, so the old bead is cut away. Nothing else gives a bond that lasts.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Cost factors for facade joints

What shapes the price:

  • Access and working height
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits
  • How much there is to seal

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • How the joints are reached, and at what height
  • Whether the building will be occupied during the work

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or send details through our quote form.

Building and refurbishing in Arundel

Arundel lies roughly 49 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Arundel 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 external mastic is timed for workable conditions and agreed with the site manager.

Older buildings in the area around Arundel, such as Ecclesden Manor, 4.3 miles to the south-east of Arundel, need care when sealed: the product has to suit soft or historic materials. New wings at hospitals like Arundel & District Community Hospital (to the north-west of Arundel) bring long runs of window and panel joints to seal.

Arundel is about 3 miles north-west of Littlehampton, in West Sussex. We cover Arundel and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. Our West Sussex coverage takes in 373 places, large and small. Sites around Brighton have their own page, about 19 miles away.

If you need facade sealing in BN18, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are London Road, High Street and Arundel Relief Road, and sites on any of them can send details for a fixed quote. Access to Arundel is via the A27 and A284 among other routes, so getting applicators and materials to site is simple. Nearby places we also cover include Crossbush (1 mile south-east), Tortington (1 mile south-west), Warningcamp (2 miles east), Lyminster (2 miles south) and Ford (2 miles south-west) for facade joints. A short drive away, we cover Worthing (7 miles east), Bognor Regis (7 miles south-west), Chichester (10 miles west), Selsey (13 miles south-west), Littlehampton (3 miles south-east) and Shoreham-by-Sea (13 miles east).

Leave it or put it right?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

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.
