Facade sealing in Blackhill

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For premises in Blackhill, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.

  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 is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

Facade sealing in Blackhill

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about cladding panel joints that have opened up and new sealant peeling off old mastic, on stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters. Whoever orders the work in Blackhill, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Sandstone and, in Aberdeen, granite buildings need care when new windows or panels are sealed against them: the right primer, a neutral-cure sealant and a colour that blends. That holds on a tenement as much as on a city-centre office.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Different surfaces, different methods

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, and we will mention any edges that need repair.

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

What happens if it’s left?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Getting access arranged for a building in Blackhill takes time, so deal with all failing joints while access is up.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Public liability insurance in place
  • Our applicators hold CSCS cards
  • Joints cleaned back to sound surfaces

Cost factors for facade joints

We price every job individually. The main factors are:

  • Quantities, in metres or numbers
  • The site’s rules and procedures
  • The product specified
  • Any access equipment needed

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • When you need the work done
  • Specification clauses that apply
  • How the joints are reached, and at what height
  • Clear photographs of the problem areas

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Questions about Blackhill

Who do we deal with for shared-part sealing on a tenement in Blackhill?

Work on shared parts is typically agreed by the owners, often through a property factor. We can quote to the factor or to the owners, for a single close or a whole block.

Is Blochairn Industrial Estate, near Blackhill, within your area?

Yes. Estates, retail parks and business parks around Blackhill, Blochairn Industrial Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

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.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Mastic packages on Blackhill sites

A number of hotels sit less than 2 miles from Blackhill. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. In Blackhill, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic follows the specification that goes with the warrant.

For contractors at a college like Glasgow Kelvin College - East End Campus, which lies south of Blackhill, perimeters and internal sealant are timed for the holidays. Recladding or extending a unit at a site like Blochairn Industrial Estate (to the west of Blackhill) brings panel joints and frame perimeters into the programme. Older buildings in the area around Blackhill, such as Provand's Lordship, which lies south-west of Blackhill, need care when sealed: the product has to suit soft or historic materials.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.
