What affects the cost of external mastic
There’s no set price list, because jobs vary so much. The quote depends on:

- Which sealant suits the joint

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

About our external mastic in The Calders
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you’re dealing with hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render, we can help.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In The Calders, work on shared parts of a tenement is normally agreed between owners, often with a factor arranging it.
A 12-month guarantee comes as standard.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
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.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Outside joints around The Calders
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.

Your questions about external mastic in The Calders
How is work on the outside of a tenement in The Calders normally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not.
Do you work for landlords with property near Wester Hailes station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Should I try DIY first?
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.
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.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
How do I get a quote for external mastic in The Calders?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.

Can you do several jobs on one visit?

What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on the building from start to finish. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In The Calders, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on
- Tell us about any water getting in

Advice
Why it’s worth doing now in The Calders
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Scottish rain finds any gap around a frame or wall joint, and in The Calders, damp can spread through stone and plaster before anyone sees it.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why book with us
- Neat joints and a tidy finish
- Domestic, commercial and hotel work
- You choose the colour before work begins
- Any old sealant cut out fully, not covered over
Read our cost guide or our reviews.
How to look after the new joints
To keep the joints looking good and working properly:
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Keep water from gutters off the wall
- Keep high-pressure jets off the joints
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, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

Signs you need external mastic in The Calders
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Any of these means the joints need attention:
- Rain getting behind render or cladding at a joint
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Sealant pulling away from one side of the joint
For landlords with property near Wester Hailes station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
