External mastic for homes and businesses in Chesser
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. If you have old sealant gone brittle and cracked and failed sealant between panels on a façade, we can put it right, on copings & trims, brickwork movement joints and joints between brick and frames alike.
Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Chesser, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
There’s a 12-month guarantee on every job, whatever its size.

What affects the cost of external mastic

- How many areas need sealing
- The type of sealant required

- Whether the work is at height
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk.
Asking for a quote
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Whether it has been sealed before
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Check external joints each spring
- Clear growth from the base of walls and joints
- Act on the first splits you see
- Wash walls gently around the sealant
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Your questions about external mastic in Chesser
Do you work for landlords with property near Slateford station?
Yes. We work for landlords and agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How do repairs to the shared parts of a tenement in Chesser get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
How much does external mastic cost in Chesser?
It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
When is the sealant fully cured?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
External mastic in Chesser: local notes
With historic houses such as Whitefoord House (about 3.2 miles north-east) nearby, there’s older building stock in the area around Chesser as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Letting a property close to Slateford station? Then split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Stenhouse Saughton Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Balgreen Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Scottish rain finds any gap around a frame or wall joint, and in Chesser, damp can spread through stone and plaster before anyone sees it.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start.

- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit

- Tell us about any water getting in
