How we handle facade sealing in Locheport

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. If you’re dealing with weathered joints at frame-to-structure perimeters and patch repairs that keep failing, we can put it right, on stone and brick facade joints, window and door perimeters and perimeter joints where frames meet the structure alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Locheport is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Locheport that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions about Locheport

Do you work on the island where Locheport is?

Yes, Locheport is within the area we cover. We cover the whole of Scotland. We group island work where we can and plan around the crossings.

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

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What sets the cost

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

  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements
  • How much existing material needs removing
  • Any access equipment needed

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around
  • How the joints are reached, and at what height

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email drawings and photos.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Don’t wait for a second leak before calling
  • Clear debris that holds water against joints
  • Confirm the survey covers external sealants in older buildings
  • Keep the sealant details on the building file

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs near Locheport are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  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. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Tell staff and tenants when we’ll be in

Different surfaces, different methods

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.

Facades, frames and programmes in Locheport

With the shore within about 1 mile, Locheport 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. In Locheport, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic package follows the approved specification.

For contractors building in or near Locheport, we seal to the drawings, the specification and the programme. Around Locheport, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Cracked or spalling substrates that need repair before sealing
  • Work on the window or framing system itself
  • Joints whose design needs changing by the specifier

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Surfaces we seal

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

What happens if it’s left?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Locheport, a repair visit takes planning, so it’s better to act early.

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
