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

Facade sealing in Letham, done properly

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. We work on cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters, and what we are called in for most is weathered joints at frame-to-structure perimeters and discoloured or dirty facade joints. One point of contact handles commercial sealant work in Letham from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Letham that means watching the forecast. We build some give into the plan and agree it with the site manager.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs near Letham are often grouped with others in the same area. Tell us how flexible your dates are.

  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. We remove the old bead and check the edges are sound.
  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.

Your questions answered

Can you work to our programme on a site in or near Letham?

Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a hospital such as Whitehills Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

How much does the work cost?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email us.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

What hours do you work?

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.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What affects the price in Letham

Each job is priced on its own details. The main factors are:

  • Distance, for remote addresses
  • Site requirements such as inductions and permits
  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Any specification or named product
  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Facade sealing in Letham: the local picture

Scotland has its own building regulations, and in Letham warrants come from the local authority verifier. We seal to the specification that sits behind the warrant. Letham is in the east of Scotland, which is drier than the west. Cold, damp starts still stop external sealing on some days. We programme around it with the site team.

On a healthcare site such as Whitehills Hospital, 4.1 miles west of Letham, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Letham is about 5 miles east of Forfar, in Angus. Our applicators travel to Letham for work on facade joints. We work across 65 places in Angus. Sites around Dundee have their own page, roughly 13 miles from Letham.

Work on facade joints is covered throughout DD8, whatever the building. For a building on The Square, Kirkgait and Gardyne Street or nearby, send details and we’ll quote for facade joints. We also cover Craichie (2 miles south-west), Tulloes (2 miles south-west), Hillend (2 miles west), Lownie Moor (3 miles west) and Kingsmuir (3 miles west). Bigger towns within reach include Arbroath (8 miles south-east), Forfar (5 miles west), Montrose (13 miles north-east), Monifieth (10 miles south), Carnoustie (9 miles south) and Kirriemuir (9 miles west).

What the job involves on each surface

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.

Brick and stone facades

Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Movement beyond what any sealant can handle
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Specialist high-level access methods

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.

Surfaces we seal

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

Common problems we fix in Letham

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:

  • Perimeter joints where frames meet the structure
  • Leaks at window and door perimeters
  • Sealant pulling away from frames or panels
  • Air leaks through failed facade joints

Sites around Letham get mastic sealed to the drawings and the programme, nothing improvised.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?
