Facade sealing in Fareham

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, and closed-cell rod sets the depth, keeping the bond to two faces. We work on perimeter joints where frames meet the structure, window and door perimeters and shopfront frames, and the usual reasons a site gets in touch are patch repairs that keep failing and air leaks through failed facade joints. A specialist sealant contractor works differently from a general builder: on jobs in Fareham, preparation and product choice get the time they need.

Older town-centre buildings in places like Fareham are often converted to new uses or extended, so new windows and cladding meet old masonry. Those junctions need a sealant and primer that suit both surfaces.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions about Fareham

Can you work on a hospital site such as Knowle 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.

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

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you cover Fareham?

Yes. Sites across Fareham are covered, and the same phone number covers every area.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

On site: what to expect

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Town-centre premises in Fareham may have limited parking, so tell us what’s nearby. Industrial and business units typically have yard or car park space.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Let building users know which areas are affected
  • Send any specification or drawings in advance
  • Flag any permit to work we will need

Advice

What the job involves on each surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod, primed where the maker specifies.

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants
  • Location, for remote and island sites
  • Backing rod, priming and other preparation

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • Any specification or named product
  • Any dates the work must fit around
  • Access details, including height
  • The postcode of the building

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Why act early in Fareham

If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once. Many buildings in towns like Fareham have been extended or altered, and joints where old meets new tend to fail first. Resealing them early protects the building behind.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Why clients in Fareham choose us

  • One contact handling all your sites
  • 12 months’ guarantee on every job
  • A range of standard colours, depending on the product
  • Colour agreed before work starts

New build and refits around Fareham

Fareham lies within about 2 miles of the sea. 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. The area within 2 miles of Fareham holds several hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

For a contractor at a hotel such as The Red Lion Hotel (1 mile east of Fareham), the mastic often has to be finished before a reopening date. When a school such as St Jude's Catholic Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. When a college such as Fareham College, less than half a mile to the south-west of Fareham, builds or refurbishes, the mastic package usually has to fit around students and staff.

Fareham sits inside our coverage and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.
