About our facade sealing in Westridge

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Westridge. Where sealant is the specified fix, we also take on coping and flashing joints. Most enquiries involve patch repairs that keep failing and weathered joints at frame-to-structure perimeters, across shopfront frames, cladding panel joints and coping and flashing joints. A single leaking joint is often how a building in Westridge first comes to us: we look at the rest while we are there and tell you what we find.

Sites around smaller places like Westridge can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Joints too narrow for the movement they take, which need redesign
  • Damaged frames that need replacing
  • Arranging specialist high-level access, which is planned with the client

If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Where we work in Westridge

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

Surface by surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we will mention any edges that need repair.

Mastic packages on Westridge sites

With the shore within about 2 miles, Westridge counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. A 2-mile radius around Westridge takes in plenty of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.

Projects at schools like Oakfield Church of England Aided Primary School work to term dates, so mastic is programmed tightly. Hotel extensions and refits, at places such as Appley Manor Hotel (0.8 miles north of Westridge), typically run between busy periods, so the sealing is squeezed into short windows.

Westridge is about 1 mile south-east of Ryde, in the Isle of Wight. We cover commercial sites throughout Westridge, for single jobs and planned programmes alike. Across the Isle of Wight, 125 places are covered, including Westridge. Portsmouth is covered too, some 7 miles away.

Anyone looking for facade sealing in PO33 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Buildings on Bullen Road, Hayward Avenue and Salisbury Road are within our area. Main routes into Westridge include the A3055. Close to Westridge, our area also takes in Elmfield (1 mile north), Oakfield (1 mile north-west), Appley (1 mile north), Pondwell (1 mile east) and Puckpool (1 mile north-east). Nearby towns on our patch include Newport (7 miles west), Cowes (8 miles north-west), Sandown (4 miles south), Shanklin (6 miles south), Ventnor (9 miles south) and East Cowes (7 miles north-west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Share access with other external trades
  • Walk the elevations once or twice a year
  • Report water ingress at frames as soon as it shows
  • Keep pressure washers away from fresh sealant

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and limits disruption.

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

FAQs: Westridge

Is a smaller place like Westridge outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Will you take on work at estates like Ryde Business Park, close to Westridge?

Yes. Our area takes in Westridge and its surroundings, with estates and business parks such as Ryde Business Park included. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is it okay to overlay old mastic?

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

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Signs you need facade sealing in Westridge

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.

Look out for the following:

  • Old perimeter mastic that has dried out
  • New sealant peeling off old mastic
  • Draughts around frames and panels
  • Perimeter sealant that has split or peeled away

On a healthcare site such as Gosport War Memorial Hospital, 5.5 miles north of Westridge, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What your quote should include

  • How the existing material will be dealt with
  • How joint depth will be controlled
  • The named product and why it was chosen
  • Can the work be phased to keep areas open?

Our contractor checklist

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking a day or two for a few elevations, and longer where access has to be moved around the building. For work around Westridge, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close
