About our facade sealing in Catisfield

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have leaks at window and door perimeters and failed seals around shopfront and entrance frames, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Catisfield is the same: the right product in a properly prepared joint.

Around places like Catisfield, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Catisfield: questions and answers

Would you work within a site like Fareham Community Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Does the sea air around Catisfield change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you replace windows or glass?

No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Site staff or a sealant specialist?

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.

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.

Signs you need facade sealing in Catisfield

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Most enquiries start with one or more of the following:

  • Air leaks through failed facade joints
  • Perimeter sealant that has split or peeled away
  • New sealant peeling off old mastic
  • Weathered joints at frame-to-structure perimeters

School extensions, at buildings such as Ranvilles Infant School, usually run to the summer holidays, mastic included.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Their approach to joint depth and backing
  • Do they follow the manufacturer’s priming guidance?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Work for main contractors and building owners

When you manage a building on behalf of an owner, 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.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Mastic packages on Catisfield sites

The sea is no more than about 2 miles from Catisfield. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Catisfield sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

Projects at colleges like Fareham College (to the east of Catisfield) tend to run to term dates, so the mastic is planned tightly. Work at a hotel such as The Bugle Hotel, 0.6 miles to the west of Catisfield, tends to be programmed around bookings, mastic included.

How the quote is worked out

We price every job individually. The main factors are:

  • Quantities, in metres or numbers
  • The product specified
  • Access and working height
  • Phasing around occupants

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

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

  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • Your programme or deadline
  • Where the site is, with the postcode

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or send details through our quote form.

Surface by surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Catisfield, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for 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.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand
  • Tell staff and tenants when we’ll be in
