Your questions answered

Do you take on work at healthcare sites like Gartnavel Royal Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Can you work at a site such as Anniesland Industrial Estate, by Knightswood?

Yes. Estates, retail parks and business parks around Knightswood, Anniesland Industrial Estate among them, are all within reach. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How much does the work cost?

Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or email us.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you replace windows or glass?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.

About our facade sealing in Knightswood

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. We work on cladding panel joints, perimeter joints where frames meet the structure and shopfront frames, and the usual reasons a site gets in touch are discoloured or dirty facade joints and air leaks through failed facade joints. Whoever orders the work in Knightswood, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Around Knightswood, city construction ranges from new offices, student housing and flats to the refurbishment of traditional stone buildings. Work comes under Scotland’s own building standards, and our job is to seal to the specification.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Damp caused by condensation inside the building
  • Replacing glass or failed glazing units
  • Damaged frames that need replacing

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly.

Joints and surfaces we work on

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

Leave it or put it right?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. In Knightswood, as across Scotland, rain finds any gap, and failed external joints let it into stone walls and around frames. Renewing them early protects the fabric.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Why clients in Knightswood choose us

  • Matching to RAL references, product permitting
  • Fully insured
  • Coloured sealants to suit the setting, where available
  • A Constructionline member, so easy to vet

Facades, frames and programmes in Knightswood

The west of Scotland, where Knightswood is, gets more rain than the east. External mastic dates are agreed with the site manager, with internal sealant kept ready for wet days. Building work in Knightswood comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. We seal to the specification that sits behind the warrant.

Building work at universities like University of Glasgow Garscube Campus, 1.2 miles to the north-east of Knightswood, is often timed for the summer, mastic included. New wings at hospitals like Gartnavel Royal Hospital (1.2 miles south-east of Knightswood) bring long runs of window and panel joints to seal.

Knightswood is about 2 miles south of Bearsden, in Glasgow. We cover Knightswood and the rest of Glasgow, with the same fixed quotes and 12-month guarantee as everywhere else. Knightswood is one of 171 places in Glasgow on our list.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. City jobs in Knightswood typically need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.

  1. First we review photos, 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. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Arrange parking or a loading space
  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000

What we’re called out for in Knightswood

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

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

  • Cold air coming in at window perimeters
  • Hard, chalky sealant that no longer flexes
  • Gaps between rainscreen or cladding panels
  • Perimeter sealant that has split or peeled away

Work at a hotel such as Leonardo Inn Hotel Glasgow West End (to the south-east of Knightswood) tends to be programmed around bookings, mastic included.

What your quote should include

  • The named product and why it was chosen
  • What level of public liability insurance do they hold?
  • Their plan for phasing and protecting the area
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Keeping the joints sound

After handover, these steps help:

  • Don’t wait for a second leak before calling
  • Insist on a full cut-out when joints are renewed
  • Check that rainwater leaves the facade the way it was designed to
  • Brief window cleaners about newly sealed joints

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.
