When to call us in Ninewells
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
Letting a property close to Invergowrie station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

External mastic for homes and businesses in Ninewells
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. If you are dealing with gaps where render, brick and frames meet and brick movement joints where the sealant has split, we can help, on render & cladding joints, copings & trims and concrete & block alike.

Ninewells: your questions answered
Who arranges sealant work on the shared parts of a tenement in Ninewells?
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, and we can quote for the factor or the owners directly.
Can you help a landlord with a rental near Invergowrie station?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Where are you based?
Mr Mastic is based in Crawley. We cover Ninewells and the rest of Dundee.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
How long will you be here?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on the amount of work. In a city area like Ninewells, 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 start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
How to get a quote
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we will take it from there.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Make sure movement joints aren’t pointed over
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Why act early in Ninewells
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. For landlords in Ninewells, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Colour agreed with you before work begins
- ARBOMaster approved applicator

Outside joints around Ninewells
Ninewells is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Camperdown House (about 1.5 miles north) nearby, there’s older building stock in the area around Ninewells as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Menzieshill High School? Then larger buildings have long runs of movement joint that eventually need resealing. Historic houses such as Camperdown House, about 1.5 miles north, show how far back building around Ninewells goes, and older homes nearby need a sealant that suits their walls.
