About our expansion joint sealing in Rhu
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. The enquiries we see most involve torn sealant in brick or block movement joints and new sealant over old, now failing, on car park decks and ramps, podiums and floor movement joints and precast concrete panel joints. Looking for mastic applicators who cover Rhu? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around smaller Scottish places like Rhu, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Slabs and yards take vehicles, rain and frost.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What the job involves on each surface
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 priming where the maker calls for it.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
We work for building owners and managing agents on everything from one building to a spread of sites around Rhu. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Warehouse floors and decks around Rhu
Rhu lies within about 1 mile of the sea. 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. Rhu is on Scotland’s wetter western side. Open joints in external slabs take a lot of water. Dry spells are used for the external joints.
For an estate such as Victoria Infirmary, 2.7 miles south-east of Rhu, the joints in ramps, decks and long building elevations all need attention over time.
Rhu is about 2 miles west of Helensburgh, in Argyll and Bute. Looking for expansion joint sealing in Rhu? We can help. Across Argyll and Bute, 124 places are covered, Rhu among them. There’s a separate page for Glasgow, about 23 miles away.
If you need expansion joint sealing in G84, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on Church Road, Station Road and Inchgower Grove. Sites close to Rhu are covered too, including Rosneath (1 mile south-west), Shandon (1 mile north-west), Clynder (1 mile west), Helensburgh (2 miles east) and Rahane (3 miles north-west).

What happens if it’s left?
A torn seal left alone normally gets worse. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. For buildings near Rhu, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. For a building near Rhu, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- 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.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Make sure the joints can be reached
- Point out any areas we must not close

Cost factors for movement joints
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Working within restricted access windows
- The product specified
- Quantities, in metres or numbers
- How accessible the joints are
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- What the building is and how it’s used
- Anything awkward about access or site hours
- Your programme or deadline
- Where the site is, with the postcode
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or send details through our quote form.
When to call us in Rhu
Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Most enquiries start with one or more of the following:
- Car park joints leaking onto vehicles below
- Brittle, chalky sealant on external joints
- Sealant pulling off the joint face
- Spalled or broken joint edges in floors and decks
In a school such as Lomond School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
Your questions answered
Does a coastal location like Rhu 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.
Is Rhu too far out for you?
No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.
Why do our movement joints keep failing?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing since each needs a different fix.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Are you insured?
Yes. We’re fully insured, including public liability cover.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you use silicone or polyurethane in movement joints?
We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
