FAQs for Penilee
Do you work for landlords with property near Hillington West station?
Yes. We work for landlords and letting agents as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How is work on the outside of a tenement in Penilee usually arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Do you come to Penilee?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
About our external mastic in Penilee
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we do not skip that step. We are often asked to deal with failed sealant between panels on a façade and joints with sealant missing in places, on render & cladding joints, brickwork movement joints and façade panels.
Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Penilee, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
A one-year guarantee comes as standard.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. In a city area like Penilee, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Honest limits

- Structural movement, which needs a surveyor or engineer

- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

Outside joints around Penilee
Penilee is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Pollok House, about 2.6 miles south-east, is one of the historic houses in the wider area around Penilee, and older homes nearby need a sealant that suits their walls. Rented homes near Hillington West station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Penilee is about 1 mile south-east of Renfrew, in Glasgow. Jobs in Penilee get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Penilee is one of 183 places in Glasgow where we work.
Postcode districts we cover here for external mastic: G52 and PA1. You’ll find streets such as Watt Road, Rylees Road and School Road, and we cover them all.

What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Landlords, agents and businesses in Penilee
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Housing providers, facilities teams and property managers book us too in Penilee and across Glasgow. We can quote a run of properties together, and we’re fully insured for the work.
Common problems we fix in Penilee
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Signs it’s time to call us include:
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
If you look after a building such as Rosshall Academy, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before booking

What else we do in Penilee
Why act early in Penilee
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Penilee, damp can travel a long way before it shows.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear quote before work begins.
