Questions about Cardross

Is Clydebuilt Shopping Park, near Cardross, within your area?

Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint, and either way it needs a sound seal.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What timescale should we allow for resealing expansion joints?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
About our expansion joint sealing in Cardross
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. We work on cladding panel joints, car park decks and ramps and blockwork control joints, and what we are called in for most is sealant pulling off the joint face and previous reseals laid over old sealant. Searching for sealant specialists in Cardross? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For outside joints near Cardross, the Scottish weather sets the timetable: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or email us and we’ll arrange a return visit.

Expansion joint sealing around Cardross: points for this area
The sea is no more than about 1 mile from Cardross. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Cardross is on Scotland’s wetter western side. Open joints in external slabs take a lot of water. External sealing is booked for dry spells, with some give in the dates.
For an estate such as Dumbarton Joint Hospital (2.5 miles south-east of Cardross), the joints in ramps, decks and long building elevations all need attention over time. Retail sites such as Clydebuilt Shopping Park, 2.6 miles to the south-west of Cardross, have car park, service yard and shop floor joints under constant traffic.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Tell us who will meet us and how to get in at your building near Cardross. That goes into the plan alongside the quote.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Move anything stored against the joints
- Send any specification or drawings in advance
