Mastic packages on Lochdon sites

Lochdon is within about 1 mile of the coast. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Projects in Lochdon follow Scotland’s building regulations, with the local authority acting as verifier. Our job is to seal to that specification.

New wings at hospitals like Mull and Iona Community Hospital (to the north of Lochdon) bring long runs of window and panel joints to seal. For contractors building in or near Lochdon, we seal to the drawings, the specification and the programme.

Lochdon is in Argyll and Bute. Lochdon sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Argyll and Bute coverage takes in 124 places. Glasgow is covered too, some 68 miles away.

Facade sealing for commercial buildings in Lochdon

Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. If you have leaks at window and door perimeters and gaps between rainscreen or cladding panels, we can help, on cladding panel joints, perimeter joints where frames meet the structure and shopfront frames alike. A single leaking joint is often how a building in Lochdon first comes to us: we look at the rest while we are there and tell you what we find.

In smaller places such as Lochdon, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Location, for remote and island sites
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements
  • How much there is to seal

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Any specification or named product

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email the details over.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Jobs near Lochdon are often grouped with others in the same area. Tell us how flexible your dates are.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Add perimeter sealant to planned maintenance checks
  • Investigate damp beside windows promptly
  • Combine resealing with other works that need access
  • Record the product and colour used on each elevation

After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.

Lochdon: questions and answers

Is Lochdon off your patch?

No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Mull and Iona Community Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Which sealant do you use on facades?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Joints too narrow for the movement they take, which need redesign
  • Work on the window or framing system itself
  • Damaged frames that need replacing

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Where we work in Lochdon

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

What the job involves on each surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.
