Facade sealing near Longside

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Facade sealing in Longside, done properly

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. We work on perimeter joints where frames meet the structure, stone and brick facade joints and shopfront frames, and the usual reasons a site gets in touch are perimeter sealant that has split or peeled away and leaks at window and door perimeters. Searching for sealant specialists in Longside? We’ve been sealing commercial buildings since 2005.

External sealing around Longside depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Damp caused by condensation inside the building
  • Specialist high-level access methods
  • Work on the window or framing system itself

If you’re not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Surfaces we seal

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

Facade sealing in Longside: the local picture

Scotland has its own building regulations, and in Longside warrants come from the local authority verifier. The mastic package follows the approved specification. The east of Scotland, where Longside is, gets less rain than the west. Winter mornings can still bring frost and condensation on steel and glass. External mastic is planned with the site manager for workable conditions.

Recladding or extending a unit at a site like Thunderton Industrial Estate (to the east of Longside) brings panel joints and frame perimeters into the programme. On a healthcare site such as Ugie Hospital (5.6 miles east of Longside), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Longside is about 5 miles west of Peterhead, in Aberdeenshire. Any commercial site in Longside is covered, whether it’s a single job or part of a planned programme. 179 places across Aberdeenshire fall within our area, Longside among them. For work in that direction, see our Aberdeen page, about 26 miles away.

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, so preparation and product choice matter.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint rather than the system it surrounds.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is 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, which is what makes a joint last.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around Longside, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. We plan access and the order of elevations with the client.
  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. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
  • Confirm the product named in the specification
  • Move anything stored against the joints

Quoting for work in Longside

Your fixed quote is built from the real scope. It allows for:

  • The total length or number of joints
  • Phasing around occupants
  • Joint width, depth and condition
  • How much existing material needs removing

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

However big the job, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings
  • Specification clauses that apply
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send photos by email.

Commercial clients in Longside

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

FAQs: Longside

Would you work within a site like Ugie Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Longside off your patch?

No. Places such as Longside are covered as much as the big towns. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can phone 01277 525 020 or email us to arrange a visit. Failed perimeter sealant is a common cause, but not the only one.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.

How many days will you need on site?

That varies with the scale of the job, though a typical visit usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
