About our mastic sealing in Loch Baghasdail

We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. Most enquiries involve a mix of products and colours from past repairs and the same joint failures repeated across a portfolio, on communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Loch Baghasdail, preparation and product choice get the time they need.

Outside mastic in Scotland needs dry joints and the right temperature, so work around Loch Baghasdail is planned with the forecast. Programmes allow for the weather.

Our workmanship is guaranteed for 12 months, in Loch Baghasdail as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Loch Baghasdail, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

What we need from you

  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open
  • Share your working hours and any access restrictions

Related advice

Do you need mastic sealing in Loch Baghasdail?

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.

Common reasons buildings call us in:

  • Cracked, hardened mastic round windows on a block
  • Draughts at frames across a block
  • The same joint failures repeated across a portfolio
  • No planned programme for sealant

Owners near Loch Baghasdail can renew frame and external mastic block by block on one programme.

Planned mastic for Loch Baghasdail portfolios

Loch Baghasdail is within about 1 mile of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Island jobs, Loch Baghasdail among them, are planned around the ferry and the forecast. Photos of each elevation and a list of buildings let us plan the whole programme.

Near Loch Baghasdail, we review each elevation first so the quote covers what actually needs doing.

What the job involves on each surface

Estate-wide resealing programmes

A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.

Planned maintenance

Resealing can be scheduled alongside other planned works, building by building.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Check sealant joints during planned building inspections
  • Plan resealing building by building rather than complaint by complaint
  • List the paperwork your organisation requires when you send details
  • Encourage occupiers to report problems at frames

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
  • Frames that are rotten, warped or broken
  • Broken glass or failed sealed units

If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.

Joints and surfaces we work on

  • Communal entrances and stairwells
  • Window and door perimeters on blocks
  • Balcony and threshold joints
  • Communal kitchens and washrooms
  • Shopfronts below residential blocks
  • External wall and movement joints

FAQs: Loch Baghasdail

Does a coastal location like Loch Baghasdail affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Can you take on a job in Loch Baghasdail, on the island?

Yes. Islands are part of our area, Loch Baghasdail included. We group island work where we can and plan around the crossings.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Can you quote from photos?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
