Facade sealing in Liff, done properly

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. If you are dealing with unsightly perimeter sealant on a visible elevation and water coming in around window frames, we can help, on stone and brick facade joints, shopfront frames and perimeter joints where frames meet the structure alike. A single leaking joint is often how a building in Liff first comes to us: we look at the rest while we’re there and tell you what we find.

External sealing around Liff depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Report water ingress at frames as soon as it shows
  • Note when each elevation was last resealed
  • Insist on a full cut-out when joints are renewed
  • Combine resealing with other works that need access

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Work on the window or framing system itself
  • Joints too narrow for the movement they take, which need redesign
  • Specialist high-level access methods

If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.

Joints and surfaces we work on

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

What the job involves on each surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather and need a durable external sealant.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Tell us who will meet us and how to get in at your building near Liff. That goes into the plan alongside the quote.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000

Quotes

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or use the quote form.

Advice

What sets the cost

Before we quote, we look at:

  • The product specified
  • How much existing material needs removing
  • Whether the work must be split into stages
  • The site’s rules and procedures

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Any dates the work must fit around
  • Any specification or named product
  • Anything awkward about access or site hours
  • The postcode of the building

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Facade sealing in Liff: the local picture

Liff sits close to the coast, within about 3 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Projects in Liff follow Scotland’s building regulations, with the local authority acting as verifier. Our job is to seal to that specification.

When units on a site such as Wester Gourdie Industrial Estate, 1.4 miles south-east of Liff, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Extensions at sites like Ninewells Hospital (to the south-east of Liff) typically sit beside working departments, and the mastic follows strict access rules.

Liff is about 4 miles west of Dundee, in Angus. Liff sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Angus coverage takes in 65 places, large and small.

Business premises anywhere in DD2 are within our area for facade joints. For a building on Church Road, Neddertoun View and Kirkcroft Brae or nearby, we can quote for facade joints. We also cover Invergowrie (1 mile south-east), Muirhead (1 mile north-east), Birkhill (1 mile north-east), Camperdown (1 mile east) and Gowrie Park (1 mile south-east). Further afield, our area takes in Forfar (13 miles north-east), Monifieth (10 miles east), Carnoustie (14 miles east), Kirriemuir (14 miles north), Hunter's Town (13 miles east) and Gardynebourg (13 miles east).

Signs you need facade sealing in Liff

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

Look out for the following:

  • Unsightly perimeter sealant on a visible elevation
  • Weathered facade joints that have lost their grip
  • Damp patches beside frames after rain
  • Weathered joints at frame-to-structure perimeters

University estates such as University of Dundee, 4.1 miles to the south-east of Liff, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

What to look for in a quote

  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid
  • The named product and why it was chosen
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

Liff: questions and answers

Does a coastal location like Liff affect which sealant is used?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Is a smaller place like Liff outside your area?

Not at all. Liff is within our area. Our area covers all of Scotland, cities, towns and islands alike. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work on upper floors?

We agree access with the client at the start. Let us know what access is in place or planned, and we will price the work around it.

Is your workmanship covered by a guarantee?

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

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

What will the job cost?

We don’t publish prices, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
