Facade sealing in Mallaig

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 Mallaig, done properly

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on window and door perimeters, perimeter joints where frames meet the structure and stone and brick facade joints, and what we are called in for most is old perimeter mastic that has dried out and leaks at window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Mallaig is the same: the right product in a properly prepared joint.

Construction around smaller Scottish places like Mallaig is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.

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

New build and refits around Mallaig

With the shore within about 1 mile, Mallaig counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Building work in Mallaig comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification.

When units on a site such as Mallaig Industrial Estate, under half a mile west of Mallaig, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. School extensions, at buildings such as Mallaig High School, normally run to the summer holidays, mastic included.

Mallaig (Gaelic: Malaig) is in Highland. Businesses, contractors and managing agents in Mallaig can call on us for facade joints. We work across 256 places in Highland.

If you need facade sealing in PH41, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Station Road, East Bay and Lochnevis Terrace. Just outside Mallaig, we also work in Morar (2 miles south), Glenancross (3 miles south), Ardvasar (5 miles north-west), Armadale (5 miles north-west) and Kilbeg (6 miles north). Where a site is remote or on an island, travel and materials need planning ahead.

Around Mallaig

Locally, jobs take us to sites close to The Steam Inn, among other places. Mallaig has its own railway station: Mallaig station. Other landmarks nearby include Mallaig Heritage Centre (under half a mile west). Not far away are Loch an Nostarie.

Common problems we fix in Mallaig

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

Clients normally get in touch after noticing something like this:

  • Facade joints cracked through the middle
  • Perimeter joints where frames meet the structure
  • Water coming in around window frames
  • Hard, chalky sealant that no longer flexes

Hotel extensions and refits, at places such as Marine Hotel, less than half a mile west of Mallaig, normally run between busy periods, so the sealing is squeezed into short windows.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Specialist high-level access methods
  • Installing or repairing glazing systems
  • Joints too narrow for the movement they take, which need redesign

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

What we seal

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

Should maintenance staff do it?

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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Your questions answered

Does your area include sites such as Mallaig Industrial Estate, near Mallaig?

Yes, sites like Mallaig Industrial Estate are within our area, along with the rest of Mallaig. Send details of the unit and the work through our quote form for a quick quote.

Does the sea air around Mallaig change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Do you provide access for facade work?

That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we will plan the work with you.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building near Mallaig, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  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

  • Move anything stored against the joints
  • Send your site hours and access windows
  • Agree which areas must stay open

Cost factors for facade joints

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

  • The product specified
  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

What to include in your enquiry

However big the job, these details speed things up:

  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists
  • The postcode of the building
  • Your programme or deadline

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Plan facade sealing alongside redecoration
  • Keep pressure washers away from fresh sealant
  • Avoid patch repairs on failed facade joints
  • Add perimeter sealant to planned maintenance checks

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.
