External mastic for homes and businesses in Lambhill
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have water getting into walls through failed joints and failed sealant between panels on a façade, we can put it right.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. For a tenement in Lambhill, repairs to shared parts are normally agreed between the owners, often through a property factor.
There’s a 12-month guarantee on every job, large or small.

What affects the cost of external mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- When we can work, for business premises
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
Asking for a quote
There’s no need for technical detail. Just tell us:
- The type of property
- Where the property is
- How we’d reach the joints
- What’s wrong with the joints now
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.
Why deal with it now?
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. For landlords in Lambhill, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What you get with us
- We agree the colour with you first
- Quality sealants from Arbo and Everbuild
- Anti-fungal silicone where joints get wet
- Domestic, commercial and hotel work

Lambhill questions
Is Lambhill in your area for external mastic?
Yes. We work across all of Scotland, and Lambhill is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Can you help a landlord with a rental near Possilpark & Parkhouse station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
What do you need from me for a quote?
Tell us what needs doing and where, with pictures by email if possible. If we need more, we will ask.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before any work starts, matched as closely as the range allows.
Honest limits
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Subsidence or other structural problems
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.
Joints and surfaces we work on
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Concrete & block
- Copings & trims
- Brickwork movement joints
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. In a city area like Lambhill, 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 inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

What the job involves on each surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant is not too deep.
