Facade sealing in Bouldnor

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

When to call us in Bouldnor

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.

Look out for the following:

  • Old perimeter mastic that has dried out
  • Weathered joints at frame-to-structure perimeters
  • Leaks at window and door perimeters
  • Previous reseals run over old sealant

School extensions, at buildings such as Yarmouth Church of England Aided Primary School, usually run to the summer holidays, mastic included.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether primer will be used where the manufacturer specifies it
  • The named product and why it was chosen
  • Can the work be phased to keep areas open?

Our contractor checklist

Facade sealing for commercial buildings in Bouldnor

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. Most enquiries involve air leaks through failed facade joints and gaps between rainscreen or cladding panels, on stone and brick facade joints, cladding panel joints and window and door perimeters. Searching for sealant specialists in Bouldnor? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For a site near Bouldnor, 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. Should something we installed fail, phone 01277 525 020 or send photos by email and we will come back to it.

Questions we’re asked in Bouldnor

Our building in Bouldnor is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Do you take on work at healthcare sites like Lymington New Forest Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is old mastic on our building likely to contain asbestos?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Can you find out why a window is leaking?

Yes. We check the sealant joints and report what we find as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you provide access for facade work?

That varies with the building and the access on offer. When you ring 01277 525 020 or send photos by email, describe the access.

Work for main contractors and building owners

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Bouldnor can sit alongside others in a wider programme across the Isle of Wight.

Facade sealing in Bouldnor: the local picture

The sea is no more than about 1 mile from Bouldnor. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. A number of hotels sit less than 2 miles from Bouldnor. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

On a healthcare site such as Lymington New Forest Hospital, 5.2 miles to the north-west of Bouldnor, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Older buildings in the area around Bouldnor, such as Mottistone Manor, which lies south-east of Bouldnor, need care when sealed: the product has to suit soft or historic materials.

Bouldnor is about 5 miles south-east of Lymington, in the Isle of Wight. Bouldnor sits inside our coverage and the rest of the Isle of Wight, with the same fixed quotes and 12-month guarantee as everywhere else. 125 places across the Isle of Wight fall within our area, Bouldnor among them. Our Southampton page has more on work in that area.

Commercial sites across PO41 are covered. Buildings on The Vineyard, Port La Salle and Waters Edge are within our area for facade joints. Just outside Bouldnor, we also work in Yarmouth (1 mile west), Cranmore (1 mile east), Hamstead (2 miles north-east), Shalfleet (3 miles east) and Thorns Beach (4 miles north). Further afield, our area takes in Newport (8 miles east), Ryde (14 miles east), Cowes (8 miles north-east), Sandown (14 miles east), Shanklin (14 miles east) and Ventnor (14 miles south-east). For island and remote sites, travel and materials need planning ahead.

Local landmarks in Bouldnor

Locally, jobs take us to sites close to Bugle Hotel and the streets around them. Bouldnor’s nearest station is Lymington Pier station, about 4.2 miles north-west. Nearby you will also find Ferguson Family Museum (1.9 miles south-west) and Yarmouth Castle (1 mile west). Not far away are Compton Down and Lymington and Keyhaven Marshes Nature Reserve.

Different surfaces, different methods

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair before sealing.

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Record the product and colour used on each elevation
  • Check that rainwater leaves the facade the way it was designed to
  • Add perimeter sealant to planned maintenance checks
  • Investigate damp beside windows promptly

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Joints too narrow for the movement they take, which need redesign
  • Render or concrete edges that have broken away
  • Damp caused by condensation inside the building

If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Bouldnor are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We start with photos, 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 goes on where the product data asks for 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.

Preparing the site

  • Warn occupants and staff about the work
  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs
