Facade sealing for Dibden sites

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

Surface by surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface.

Facade sealing in Dibden, done properly

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on stone and brick facade joints, cladding panel joints and coping and flashing joints, and what we’re called in for most is failed sealant on precast panel joints and hard, chalky sealant that no longer flexes. A single leaking joint is often how a building in Dibden 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.

On a small site around Dibden, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Damp caused by condensation inside the building
  • Work on the window or framing system itself
  • Providing access systems for the work

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

Surfaces we seal

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

Dibden: questions and answers

Is Dibden off your patch?

Not at all. Dibden is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you cover business parks and estates near Dibden, such as Hardley Industrial Estate?

Yes. Our area takes in Dibden and its surroundings, with estates and business parks such as Hardley Industrial Estate included. Photos and a short description are enough for a first look.

How do I request a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Common problems we fix in Dibden

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone.

It’s worth sending us details if you spot any of the following:

  • Leaks at window and door perimeters
  • Failed seals around shopfront and entrance frames
  • New sealant peeling off old mastic
  • Sealant pulling away from frames or panels

When a school such as Applemore College is extended or refurbished, the mastic package is often squeezed into the holidays.

What your quote should include

  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?
  • The terms of the workmanship guarantee
  • Their pre-qualification and accreditations

Our contractor checklist

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building. For a job in Dibden, the main thing is a clear picture of the work. A fixed quote follows.

  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. The finished joints are checked with you.

Before we start on site

  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work
  • Agree which areas must stay open

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email us.

Advice

Building owners, agents and FMs in Dibden

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

Should maintenance staff do it?

Certain joints really need a specialist: 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Facades, frames and programmes in Dibden

Dibden lies within about 2 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

For contractors refurbishing units at places like Hardley Industrial Estate, 2.1 miles to the south-east of Dibden, the mastic covers cladding panels, roller-door and window perimeters. Building work at universities like Southampton Solent University (to the north of Dibden) is often timed for the summer, mastic included.
