Facade sealing for Rackham sites

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

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Specialist high-level access methods
  • Damaged frames that need replacing
  • Installing or repairing glazing systems

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.

Where we work in Rackham

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

How we handle facade sealing in Rackham

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. If you’re dealing with air leaks through failed facade joints and new sealant peeling off old mastic, we can put it right, on shopfront frames, cladding panel joints and window and door perimeters alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Rackham, that means joint design, primers and backing rod as standard.

Sites around smaller places like Rackham can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

From enquiry to sign-off

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Rackham can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work 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 the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Point out parking and an unloading spot
  • Send any specification or drawings in advance
  • Move anything stored against the joints

Advice

Owners, agents and contractors

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What happens if it’s left?

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Older rural buildings around Rackham 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.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • Old sealant cut out, never sealed over
  • Matching to RAL references, product permitting
  • Products installed to the manufacturer’s instructions
  • A fixed quote before work starts

When to call us in Rackham

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Any of the following is a good reason to get the joints checked over:

  • Failed seals around shopfront and entrance frames
  • Hard, chalky sealant that no longer flexes
  • Gaps between rainscreen or cladding panels
  • Previous reseals run over old sealant

Older buildings in the area around Rackham, such as Parham House, which lies north-east of Rackham, need care when sealed: the product has to suit soft or historic materials.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid
  • The named product and why it was chosen

Choosing a commercial sealant contractor

Facades, frames and programmes in Rackham

Rackham is about 44 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.

Units on estates such as Quell Farm Industrial Estate, 1.7 miles north-west of Rackham, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor working at a hospital such as Arundel and District Hospital, which lies south-west of Rackham, perimeter and facade sealing is planned around patients and deliveries.

Rackham is about 7 miles north of Littlehampton, in West Sussex. Anywhere in RH20, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across West Sussex, 373 places are covered, Rackham among them. There’s a separate page for Brighton, roughly 17 miles from Rackham.

Questions we are asked in Rackham

Can you work on a hospital site such as Arundel and District Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Will you take on work at estates like Quell Farm Industrial Estate, close to Rackham?

Yes. Our area takes in Rackham and its surroundings, with estates and business parks such as Quell Farm Industrial Estate included. Photos and a short description are enough for a first look.

Can staff carry on working while you are here?

In most cases, yes. Phased work can be planned so areas stay in use.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

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.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
