About our expansion joint sealing in Lochwinnoch
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. Site teams most often ask us about new sealant over old, now failing and spalled or broken joint edges in floors and decks, across brickwork movement joints, blockwork control joints and podiums and floor movement joints. A specialist sealant contractor works differently from a general builder: in Lochwinnoch, that means joint design, primers and backing rod as standard.
In smaller places such as Lochwinnoch, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Concrete slabs and yards there take vehicles and weather.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

When to call us in Lochwinnoch
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.
Things that typically lead to an enquiry:
- Torn sealant in brick or block movement joints
- Damp inside where a wall movement joint has failed
- Brittle, chalky sealant on external joints
- Leaks through car park deck joints onto the level below
For floors and slabs around Lochwinnoch, the product is chosen for the traffic and the movement at each joint.
Before you book anyone
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
- How the existing material will be dealt with
- Do they follow the manufacturer’s priming guidance?
Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Lochwinnoch, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- We look at the joints, their width and how they’ve failed.
- 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.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000

Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lochwinnoch can sit alongside others in a wider programme across Renfrewshire.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

FAQs: Lochwinnoch
Must our site in Lochwinnoch stop work while the joints are done?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
Is hospital work, at somewhere like Merchiston Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Does weather matter for sealant work?
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. Inside work is seldom held up.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How the quote is worked out
We price every job individually. The things that drive the figure:
- Travel to remote or island sites
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
A quote for movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- When you need the work done
- Whether an asbestos survey exists
- Specification clauses that apply
- The site address and postcode
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or email the details over with what you know.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Inspect movement joints alongside other routine building checks
- Keep product details with the building records for the next reseal
- Keep racking legs and heavy point loads off floor joints
- Brief car park operatives to protect joint lines during winter clearance
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.
