Facade sealing in Flansham

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

How we handle facade sealing in Flansham

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on perimeter joints where frames meet the structure, cladding panel joints and window and door perimeters, and the usual reasons a site gets in touch are perimeter sealant that has split or peeled away and weathered joints at frame-to-structure perimeters. Whoever orders the work in Flansham, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Flansham bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions about Flansham

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

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is hospital work, at somewhere like Bognor Regis War Memorial Hospital, something you do?

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

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.

Do you replace failed glazing units?

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

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Keep sills, gutters and drainage paths clear
  • Ask about asbestos in pre-2000 mastic
  • Never let anyone seal over old sealant
  • Inspect facade joints on a regular cycle

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.

Different surfaces, different methods

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.

Site staff or a sealant 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 where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Sites and facades in and around Flansham

With the shore within about 2 miles, Flansham counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. There are a number of hotels within about 2 miles of Flansham. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Work at a hotel such as Ancton House Hotel, 1.4 miles east of Flansham, tends to be programmed around bookings, mastic included. Building work at universities like University of Chichester (Bognor Campus) (to the south-west of Flansham) is often timed for the summer, mastic included. Extensions at sites like Bognor Regis War Memorial Hospital (to the south-west of Flansham) usually sit beside working departments, and the mastic follows strict access rules.

Flansham is about 2 miles north-east of Bognor Regis, in West Sussex.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Flansham, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  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. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.
