Contractors’ notes for Rowner

Rowner sits close to the coast, within about 2 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Rowner is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

On a campus such as University of Portsmouth - North Zone, which lies south-east of Rowner, new teaching buildings and residences are typically built and refurbished around the academic year. For contractors at a school such as Bridgemary School, sealing has to be finished before term starts.

Rowner is about 2 miles north-west of Gosport, in Hampshire. Businesses, contractors and managing agents in Rowner use us for work on facade joints, as part of our coverage of Hampshire. Across Hampshire, 723 places are covered, including Rowner.

Facade sealing for commercial buildings in Rowner

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We plan for that and keep you updated. We work on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints, and the failures we are asked to look at most are perimeter joints where frames meet the structure and cladding panel joints that have opened up. Searching for sealant specialists in Rowner? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around places like Rowner, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or send photos by email and we will arrange a return visit.

Different surfaces, different methods

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex as the frame moves.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building. For a site in Rowner, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  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. 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. The finished joints are checked with you.

Before we start on site

  • Share your working hours and any access restrictions
  • Have the specification and drawings to hand
  • Agree which areas must stay open

What affects the price in Rowner

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Induction, permit and paperwork requirements

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • The site address and postcode
  • When you need the work done
  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available

For a fixed quote, phone 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Installing or repairing glazing systems
  • Arranging specialist high-level access, which is planned with the client
  • Damaged frames that need replacing

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.

Where we work in Rowner

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

What we are called out for in Rowner

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

It’s worth sending us details if you spot any of the following:

  • Water coming in around window frames
  • Previous reseals run over old sealant
  • Old perimeter mastic that has dried out
  • Cold air coming in at window perimeters

Further education sites such as St Vincent College, 2.2 miles south-east of Rowner, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Questions to ask before you appoint anyone

Common questions from Rowner clients

Does a coastal location like Rowner affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Do you cover business parks and estates near Rowner, such as Brockhurst Gate Retail Park?

Yes. Estates, retail parks and business parks around Rowner, Brockhurst Gate Retail Park among them, are all within reach. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How is access to upper-level joints handled?

That varies with the building and the access on offer. Share what access exists or is planned when you send details.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
