About our facade sealing in Clydebank

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have failed sealant on precast panel joints and unsightly perimeter sealant on a visible elevation, we can put it right, on stone and brick facade joints, cladding panel joints and shopfront frames alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Clydebank, that means joint design, primers and backing rod as standard.

Weather windows matter for outside mastic in a town like Clydebank: joints must be dry and above the product’s minimum temperature. We keep in touch with the site manager so external work goes ahead on the right days.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

New build and refits around Clydebank

Clydebank is within about 3 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. A number of hotels sit less than 2 miles from Clydebank. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Units on estates such as Clydebank Business Park (to the south of Clydebank) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a healthcare site such as Golden Jubilee National Hospital, 0.9 miles to the south-west of Clydebank, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Clydebank is about 7 miles north-west of Glasgow, in West Dunbartonshire. We cover commercial sites throughout Clydebank, whether it’s a single job or part of a planned programme. Clydebank is one of 22 places in West Dunbartonshire on our list for facade joints. For work in that direction, see our Glasgow page, about 7 miles away.

We take on facade joints across the G81, G60 and G14 postcode area. We cover commercial and managed buildings on Carinthia Square, Station Road and Broom Drive and the roads nearby. Access to Clydebank is via the A82 and A810. Just outside Clydebank, we also work in Hardgate (1 mile north-east), Drumry (1 mile south-east), Dalmuir (1 mile south-west), Faifley (1 mile north-east) and Duntocher (1 mile north). Further afield, our area takes in Dumbarton (6 miles west), Alexandria (8 miles north-west), Crosslet (6 miles west), Balloch (9 miles north-west), Dalreoch (7 miles west) and Kirktonhill (7 miles west).

What’s near Clydebank

For rail, the closest station is Singer station, about 0.6 miles south of the centre. Well-known places in the area include Renfrew Museum (2.7 miles south) and Golden Jubilee National Hospital (0.8 miles south-west). For a walk, there’s Dalnottar hill and Cochno Loch.

Common questions from Clydebank clients

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

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Can you take on a job at a hospital such as Golden Jubilee National Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

Is it okay to overlay old mastic?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months on every job.

Will your applicators have CSCS cards?

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

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For a unit on an estate in Clydebank, tell us about yard access and site rules. Town-centre premises may need parking planned.

  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. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

Related advice

Why deal with it now?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. A leaking joint can damage finishes, stock and fittings inside. Early action limits what needs repairing.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Why appoint us

  • 12-month guarantee on workmanship
  • Work to your specification and the manufacturer’s guidance
  • Over 20 years of commercial sealing
  • A fixed quote before work starts

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants
  • Quantities, in metres or numbers
  • The size and state of each joint

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • The type of building and who uses it
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or send photos by email.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Signs you need facade sealing in Clydebank

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.

Typical triggers for a call:

  • Leaks at window and door perimeters
  • Failed sealant on precast panel joints
  • Facade joints cracked through the middle
  • Staining on stone next to old sealant

University estates such as University of Glasgow Garscube Campus, 3.9 miles east of Clydebank, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

What your quote should include

  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • How they’ll work around occupants
  • The named product and why it was chosen
