Facade sealing in Charleston

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle facade sealing in Charleston

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. We work on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints, and the usual reasons a site gets in touch are unsightly perimeter sealant on a visible elevation and perimeter sealant that has split or peeled away. Searching for sealant specialists in Charleston? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

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.

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

How the job changes by surface

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod.

Cladding panel joints

Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, as the specification sets out.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • How much there is to seal
  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • Whether old sealant has to be cut out first

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • The site address and postcode
  • A wide shot and a close-up of the area
  • Any specification or named product
  • Anything awkward about access or site hours

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or use the quote form.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Work on a big city site in Scotland normally involves inductions and permits. Tell us the rules and we will work to them.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Flag any permit to work we’ll need
  • Make sure the joints can be reached

Advice

Sites and facades in and around Charleston

With the shore within about 2 miles, Charleston counts as a coastal location. 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. Charleston is on Scotland’s drier eastern side. Winter mornings can still bring frost and condensation on steel and glass. External dates keep a little give.

For contractors refurbishing units at places like Wester Gourdie Industrial Estate (under half a mile west of Charleston), the mastic covers cladding panels, roller-door and window perimeters. On a campus such as University of Dundee, 2.3 miles to the south-east of Charleston, new teaching buildings and residences are usually built and refurbished around the academic year. On a healthcare site such as Ninewells Hospital, 0.7 miles south of Charleston, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Charleston is about 2 miles west of Dundee, in Dundee. Across the DD2 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Dundee, 28 places are covered, Charleston among them.

We take on facade joints across the DD2 postcode area, whatever the building. For a building on Liff Road, South Road and Dunholm Road or nearby, we can quote for facade joints. Sites close to Charleston are covered too, including Menzieshill (1 mile south), Dryburgh (1 mile north-east), Ninewells (1 mile south), Gowrie Park (1 mile south-west) and Camperdown (1 mile north). Nearby towns on our patch include Broughty Ferry (7 miles east), Stobswell (3 miles east), Barnhill (7 miles east), Pitkerro (4 miles east), Whitfield (4 miles east) and Woodside (3 miles east).

Around Charleston

In Charleston, that means premises near Cox Branch Library and Balgay Hill. The nearest railway station is Invergowrie station, about 1.4 miles south-west. A little further out are Overgate Centre (2.6 miles east) and Dudhope Castle (2.1 miles east). Green spaces nearby include Balgay Hill and Piperdam Loch.

Why deal with it now?

Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Failed sealant in a shared building in Charleston can affect more than one owner. Acting early avoids disputes and bigger repairs.

A quote for facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Why appoint us

  • Matching to RAL references, product permitting
  • A Constructionline member, so easy to vet
  • Colour options checked against the specified product
  • Work to your specification and the manufacturer’s guidance

Charleston: questions and answers

Is Wester Gourdie Industrial Estate, near Charleston, within your area?

Yes. Our area takes in Charleston and its surroundings, with estates and business parks such as Wester Gourdie Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Can being near the sea in Charleston affect the sealant we need?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Do you provide access for facade work?

Access is planned with you before we quote. Let us know what access is in place or planned, and the quote will reflect it.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Confirm the survey covers external sealants in older buildings
  • Inspect facade joints on a regular cycle
  • Keep the sealant details on the building file
  • Check that rainwater leaves the facade the way it was designed to

Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

Commercial clients in Charleston

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

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.
