Mastic sealing in Cadder
Across Cadder and the rest of Glasgow, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. Most enquiries involve failed external movement joints and complaints coming in block by block, on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints. Searching for sealant specialists in Cadder? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Sandstone tenements in most Scottish cities, and granite in Aberdeen, need mastic that suits the stone, and replacement windows set into those walls need a perimeter sealant that won’t mark the stone.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When to call us in Cadder
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Typical triggers for a call:
- Movement joints with sealant missing
- Damp patches beside frames
- Estate-wide sealant that is simply worn out
- Repeated reactive repairs to the same buildings
If you manage student housing near a university such as University of Glasgow Garscube Campus (1.5 miles west of Cadder), the summer turnaround is the time for mastic.

What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- The asbestos register, for older buildings
- When you need the work done
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Commercial clients in Cadder
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 Cadder can sit alongside others in a wider programme across Glasgow.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
After the work
To get the most from the new sealant:
- Prioritise elevations facing the weather
- Include mastic in your cyclical inspections
- Make it easy for occupiers to report draughts
- Keep bins and bikes away from communal door frames
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Asbestos-containing sealant, which we don’t remove
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Misted or failed double-glazed units
Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly before you book.
What we seal
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints

From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For premises in Cadder, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Share your working hours and any access restrictions
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements
Request a quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Cadder: questions and answers
How is mastic work on a tenement’s shared parts in Cadder usually organised?
Typically through the property factor, once the owners have agreed. Send details and photos, and we’ll quote to whoever is arranging it.
Does your area include sites such as Balmore Industrial Estate, near Cadder?
Yes. We cover Cadder and the area around it, including industrial estates, business parks and retail parks such as Balmore Industrial Estate. A few photos and the unit address let us price the work.
How long does a typical visit take?
It depends on the scope, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
