Expansion joint sealing for businesses in Keills
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability, and we will confirm the colours available for the specified product.
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement.
Expansion joint sealing in Keills, done properly
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. If you have movement joints with split or torn sealant and arrises breaking up along floor joints, we can put it right, whatever the surface. A single leaking joint is often how a building in Keills first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For floor or movement joints around smaller places like Keills, we plan to finish in one visit where we can. Photos, approximate widths and what uses the floor help us bring the right materials.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Joints that move: notes for Keills
With the shore within about 1 mile, Keills counts as a coastal location. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. The west of Scotland, where Keills is, gets more rain than the east. Open joints in external slabs take a lot of water. Dry spells are used for the external joints.
Around Keills, open joints collect water and debris, and the arrises are the next to go; we’ll tell you if the edges need repairing first. Around Keills, each joint gets a filler or sealant matched to what crosses it and how much it moves.
Keills is in Argyll and Bute. Businesses, contractors and managing agents in Keills use us for work on movement joints, as part of our coverage of Argyll and Bute. Our Argyll and Bute coverage takes in 124 places, large and small. For work in that direction, see our Glasgow page (72 miles or so).
Work on movement joints is covered throughout PA46, for business premises of every kind. We also cover 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 movement joints. Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you give us a call on 01277 525 020 or email a schedule or drawings.
Landmarks near Keills
Other landmarks nearby include Finlaggan Castle (1.8 miles west). Open spaces near Keills include Loch Ballygrant and Beinn Dubh.
What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Keills before they leak.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near Keills 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.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site
- Make sure the joints can be reached
- Agree which areas must stay open
- Let us know about inductions and permits
Getting a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- The site’s rules and procedures
- Location, for remote and island sites
- Backing rod, priming and other preparation
- How accessible the joints are
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- Any dates the work must fit around
- The site address and postcode
- What the building is and how it’s used
- The asbestos register, for older buildings
To get a fixed quote, phone 01277 525 020 or email us, telling us the site location and the nature of the job. You can also send details through our quote form.
Questions about Keills
Does a site in Keills have to shut while its joints are sealed?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.
Is Keills off your patch?
Not at all. Keills is within our area. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Can you quote from photographs?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you use silicone or polyurethane in movement joints?
Movement capability matters most as set out in BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.
How much does the work cost?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Report split or peeling joint sealant early
- Leave barriers in place until fresh joint sealant has cured
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Keep scrapers and ploughs from dragging across joint sealant
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
