About our facade sealing in Keills

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you’re dealing with gaps between rainscreen or cladding panels and unsightly perimeter sealant on a visible elevation, we can put it right, on window and door perimeters, perimeter joints where frames meet the structure and coping and flashing joints alike. Searching for sealant specialists in Keills? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Sites near smaller places like Keills can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions about Keills

Our building in Keills is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Can you work to our programme on a site in or near Keills?

Yes, we work to the programme and the sequence the site sets. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Are you CHAS accredited and on Constructionline?

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

Can staff carry on working while you are here?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Keeping the joints sound

For the best life from the joints:

  • Ask about asbestos in pre-2000 mastic
  • Keep pressure washers away from fresh sealant
  • Add perimeter sealant to planned maintenance checks
  • Keep the sealant details on the building file

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal across the elevation.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Render or concrete edges that have broken away
  • Water getting in through cracked render or porous masonry
  • Replacing glass or failed glazing units

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.

Where we work in Keills

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

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • The site’s rules and procedures
  • The total length or number of joints
  • Backing rod, priming and other preparation
  • Whether old sealant has to be cut out first

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Any specification or named product
  • Where the site is, with the postcode
  • Drawings or a marked-up plan, if available
  • Access details, including height

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or send photos by email to discuss it first.

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Contractors’ notes for Keills

With the shore within about 1 mile, Keills counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Keills is in the west of Scotland, the wetter side of the country. External mastic needs dry spells, with internal work ready to fill the wet days.

Sites around Keills get mastic sealed to the drawings and the programme, nothing improvised. Hotel extensions and refits, at places such as Port Askaig Hotel (1 mile north-east of Keills), normally run between busy periods, so the sealing is squeezed into short windows.

Keills is in Argyll and Bute. Our applicators travel to Keills for work on facade joints, handled exactly as we handle every other area. 124 places across Argyll and Bute fall within our area, Keills among them. Glasgow is covered too, some 72 miles away.

Commercial sites across PA46 are covered for facade joints. Nearby places we also cover include Port Askaig (1 mile north-east), Bunnahabhain (3 miles north), Craighouse (7 miles east), Bowmore (8 miles south-west) and Port Charlotte (12 miles south-west) for facade joints. Where a site is remote or on an island, travel and materials need planning ahead.

Other landmarks nearby include Finlaggan Castle (1.8 miles west). For a walk, there’s Loch Ballygrant and Beinn Dubh.

On site: what to expect

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in 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. Travel to smaller Scottish places like Keills is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. Access, site rules and timing are settled with the client up front.
  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. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Flag any permit to work we will need

What happens if it’s left?

Topping up a failed joint typically buys very little time. A full cut-out and fresh bead is the repair that holds. Renewing every failing joint on one visit is the sensible approach for a place like Keills. Photos of each area help us quote the whole job.

A quote for facade joints depends on quantities, condition and access. Call for a quote.
