Facade sealing for businesses in Carisbrooke

Facade sealing in Carisbrooke

Managing agents and owners in Carisbrooke ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Most enquiries involve perimeter sealant that has split or peeled away and cladding panel joints that have opened up, across perimeter joints where frames meet the structure, shopfront frames and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Carisbrooke, that means joint design, primers and backing rod as standard.

Building work in places the size of Carisbrooke is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Water getting in through cracked render or porous masonry
  • Joints whose design needs changing by the specifier
  • Providing access systems for the work

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.

Facade sealing in Carisbrooke: the local picture

The area within 2 miles of Carisbrooke holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

Projects at colleges like HTP Apprenticeship College, 1.1 miles to the north-east of Carisbrooke, tend to run to term dates, so the mastic is planned tightly. New units and refits on sites such as Carisbrooke Retail Park (to the north of Carisbrooke) need their panel and perimeter joints sealed to the specification. When a school such as St Thomas of Canterbury Catholic Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Carisbrooke is about 1 mile south-west of Newport, in the Isle of Wight. We cover Carisbrooke and the rest of the Isle of Wight, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Carisbrooke is one of 125 places we cover in the Isle of Wight. Sites around Portsmouth have their own page, roughly 13 miles from Carisbrooke.

We take on facade joints across the PO30 postcode area, whatever the building. Among the streets we cover are Down Lane, Purdy Road and Castle Lane, and sites on any of them can send details for a fixed quote.

Bigger towns within reach include Ryde (7 miles east), Cowes (5 miles north), Sandown (7 miles east), Shanklin (7 miles south-east), Ventnor (8 miles south-east) and East Cowes (5 miles north). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Surface by surface

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Carisbrooke, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies 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.

Before we start on site

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Brief window cleaners about newly sealed joints
  • Keep the sealant details on the building file
  • Don’t wait for a second leak before calling
  • Inspect facade joints on a regular cycle

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
