Different surfaces, different methods

Internal decorators’ caulk

Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.

Bathrooms, en suites and washrooms

On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.

About our construction mastic in Connel

On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. If you’re dealing with frame gaps too wide for sealant alone and missed perimeter joints on a new elevation, we can put it right, on floor and skirting junctions, sanitary and kitchen joints and internal decorators’ caulk alike. One point of contact handles commercial sealant work in Connel from the first photos to the final walk-round, whether it’s one building or several.

External sealing around Connel depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, 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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Questions about Connel

Do you take on work at healthcare sites like Lorn and Islands Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is Connel too far out for you?

Not at all. Connel is within our area. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.

Can fire-rated sealing at service penetrations be included?

Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.

Do you take on mastic snagging only?

Yes. Send the snag list or photographs and we will price it.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Does weather affect external mastic work?

Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing so we usually switch to internal work when that happens.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Connel, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We start with the drawings, specification and programme.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

Preparing the site

  • Send any specification or drawings in advance
  • Tell us which areas need to stay in use
  • Tell staff and tenants when we’ll be in

Signs you need construction mastic in Connel

Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.

Things that normally lead to an enquiry:

  • Window and door perimeters that won’t pass inspection
  • Perimeter gaps outside the sealant’s range
  • Different trades sealing to different standards
  • A long mastic snag list close to completion

Work at a hotel such as Falls of Lora Hotel (less than half a mile east of Connel) tends to be programmed around bookings, mastic included.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Do they follow the manufacturer’s priming guidance?
  • How long is the guarantee, and what does it include?
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • Working within restricted access windows
  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • How much there is to seal

Larger quantities, tricky access or phasing 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 we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • The product your specification calls for
  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height
  • The site address and postcode

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or send details through our quote form.

Mastic packages on Connel sites

Connel lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. The west of Scotland, where Connel is, gets more rain than the east. External mastic dates are agreed with the site manager, with internal sealant kept ready for wet days.

New wings at hospitals like Lorn and Islands Hospital, 4.9 miles to the south-west of Connel, bring long runs of window and panel joints to seal.

Connel (Gaelic: A'Choingheal) is about 40 miles north-west of Helensburgh, in Argyll and Bute. Our applicators travel to Connel for work on mastic packages. Across Argyll and Bute, 124 places are covered, Connel among them. Sites around Glasgow have their own page, roughly 60 miles from Connel.

Work on mastic packages is covered throughout PA37, whatever the building. Streets here include St Oran's Place, Powell Place and Grosvenor Crescent, and sites on any of them can send details for a fixed quote. Just outside Connel, we also work in North Connel (1 mile north-west), Black Crofts (2 miles north-east), Ardchattan (2 miles north-east), Dunbeg (2 miles west) and Benderloch (3 miles north). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you phone 01277 525 020 or email the details over.

Leave it or put it right?

Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites. Called in at the end, the same issues surface during handover. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Connel before they leak.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
