Facade sealing in North Stoneham

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

When it isn’t the sealant

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Specialist high-level access methods
  • Movement beyond what any sealant can handle
  • Render or concrete edges that have broken away

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

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

Facade sealing in North Stoneham

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. Most enquiries involve old perimeter mastic that has dried out and perimeter sealant that has split or peeled away, on cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure. A single leaking joint is often how a building in North Stoneham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a site near North Stoneham, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we’ll quote to suit.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

For managing agents and facilities managers

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around North Stoneham, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  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. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email drawings and photos.

Surface by surface

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.

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.

Leave it or put it right?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, often turning up far from the joint. Converted and older buildings near places like North Stoneham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

A quote for facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Questions about North Stoneham

Can work at a site such as University of Southampton fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is North Stoneham too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

How is access to upper-level joints handled?

That varies with the building and the access on offer. When you speak to us on 01277 525 020 or use the quote form, describe the access, and we’ll agree the approach together.

Can you find out why a window is leaking?

Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we’ll tell you which.

Can one quote cover more than one building?

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

Mastic packages on North Stoneham sites

Plenty of hotels sit less than 2 miles from North Stoneham. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

Hotel extensions and refits, at places such as Village Hotel Club (0.8 miles north-west of North Stoneham), typically run between busy periods, so the sealing is squeezed into short windows. When a college such as Barton Peveril Sixth Form College, 0.8 miles to the north-east of North Stoneham, builds or refurbishes, the mastic package normally has to fit around students and staff. On a healthcare site such as Princess Anne Hospital, 2.7 miles south-west of North Stoneham, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

North Stoneham is about 2 miles south-west of Eastleigh, in Hampshire. Anywhere in SO50, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire, large and small.

Commercial sites across SO50 are covered. We cover commercial and managed buildings on Turnor Way and Stoneham Lane. We also cover Swaythling (1 mile south), Bassett Green (1 mile south), Mansbridge (1 mile south-east), Eastleigh (2 miles north-east) and Boyatt Wood (2 miles north-east). Bigger towns within reach include Winchester (8 miles north), Gosport (14 miles south-east), Fareham (11 miles south-east), Totton (6 miles south-west), Hedge End (4 miles south-east) and Romsey (5 miles north-west).

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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. A poor seal in places like these tends to cost more to put right later.
