Facade sealing in Gurnard

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. We work on window and door perimeters, shopfront frames and stone and brick facade joints, and what we are called in for most is air leaks through failed facade joints and discoloured or dirty facade joints. Searching for sealant specialists in Gurnard? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For a site near Gurnard, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

Work we carry out in the Isle of Wight comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email us and we’ll arrange a return visit.

Site staff or a sealant specialist?

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

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What the job involves on each surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

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’ll mention any edges that need repair.

Why act early in Gurnard

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts. Around Gurnard, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Fully insured, including public liability cover
  • Colours chosen to suit frames, cladding or finishes where possible
  • Specification-led, product-correct work
  • Health and safety: CHAS accredited

What we are called out for in Gurnard

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

These are often picked up first by site or facilities staff:

  • Unsightly perimeter sealant on a visible elevation
  • Cladding panel joints that have opened up
  • Draughts around frames and panels
  • Weathered facade joints that have lost their grip

Recladding or extending a unit at a site like Island Technology Park, 2.3 miles to the south-east of Gurnard, brings panel joints and frame perimeters into the programme.

What your quote should include

  • The named product and why it was chosen
  • Who will actually carry out the work
  • Do they follow the manufacturer’s priming guidance?
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

What sets the cost

To price the job, we consider:

  • Access and working height
  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • Joint width, depth and condition

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

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • Whether an asbestos survey exists
  • How the joints are reached, and at what height
  • Any specification or named product
  • Approximate linear metres or a joint schedule

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or send details through our quote form to discuss it first.

Building and refurbishing in Gurnard

Gurnard lies within about 1 mile of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. There are several hotels within about 2 miles of Gurnard. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

With historic properties like Osborne House, 2.3 miles east of Gurnard, in the area, refurbishment work often meets old masonry that needs compatible sealants. Hotels like New Holmwood Hotel (0.9 miles north-east of Gurnard) rarely close for long, so refurbishment mastic is phased floor by floor.

Gurnard is about 1 mile west of Cowes, in the Isle of Wight. Businesses, contractors and managing agents in Gurnard use us for work on facade joints. Gurnard is one of 125 places in the Isle of Wight on our list. Portsmouth is covered too, some 11 miles away.

We cover the PO31 postcode districts. If your site is on Cow Lane, The Avenue and Shore Road or close by, we can quote for facade joints. Nearby places we also cover include Cowes (1 mile east), Northwood (1 mile south), Rew Street (1 mile south-west), Great Thorness (2 miles south-west) and Noke Common (2 miles south) for facade joints. Bigger towns within reach include Newport (4 miles south), Ryde (7 miles east), Sandown (10 miles south-east), Shanklin (11 miles south-east), Ventnor (12 miles south-east) and Oakfield (8 miles east). For island and remote sites, we plan travel and materials carefully.

Around Gurnard

How a job runs

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 anything is cut or cleaned, with the work itself normally taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For a building around Gurnard, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Tell staff and tenants when we will be in

Advice

FAQs: Gurnard

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

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 take on work at healthcare sites like St Mary's Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
