Your questions about external mastic in Stronord
Can you do external mastic in Stronord?
Yes. Our work covers the whole of Scotland, and Stronord is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Does the coastal weather in Stronord affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do you use backing rod?
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.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
Do you work at height?
Each building is different. Send us photos and a rough idea of the height.
Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
External mastic for homes and businesses in Stronord
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. We work on joints between brick and frames, render & cladding joints and copings & trims, and people most often call us about rain getting behind render or cladding at a joint and weathered mastic that no longer stretches.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.

What else we do in Stronord
Stronord buildings and the weather
Stronord is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Stronord is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Whether the job is in Stronord itself or nearby, the right material for each joint matters as much as a neat finish.

Quotes for external mastic in Stronord
We quote each job individually. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- Any mould that needs treating
- The product the joint needs
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
When you contact us, these details help:
- The type of property
- What’s wrong with the joints now
- How we’d reach the joints
- The address or postcode of the job
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, email us at info@mrmastic.co.uk.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Make sure movement joints are not pointed over
- Don’t let climbing plants root in the sealant
- Keep water from gutters off the wall
- 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.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Why deal with it now?
A failed movement joint lets water into the wall 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. In a place like Stronord, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

The process
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 work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Stronord may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
Getting a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, drop us a line at info@mrmastic.co.uk.
Advice
Signs you need external mastic in Stronord
Buildings move more than people expect. 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.
Signs it’s time to call us include:
- Rain getting behind render or cladding at a joint
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
In and around Stronord, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
