About our external mastic in Whitehouse
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you are dealing with movement joints with cracked, split or missing sealant and rigid filler in a joint that should flex, we can help, on brickwork movement joints, copings & trims and façade panels alike.
Outside joints can only be sealed when they’re dry, so work in Whitehouse depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
There’s a 12-month guarantee on every job, large or small.

How we quote for external mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- Whether old sealant or filler has to be cut out
- The amount of work
- How many rooms, windows or areas are involved
- Working hours on commercial sites
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Roughly how big the job is
- Any previous sealing or DIY work
- The address or postcode of the job
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Walk round the building once a year and look at the joints
- Make sure movement joints aren’t pointed over
- Check the sealant is paintable before painting near it
- Wash walls gently around the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
FAQs for Whitehouse
Does living near the coast affect external mastic in Whitehouse?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you cover Whitehouse for external mastic?
Yes, Whitehouse is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Is there a guarantee?

Will the new joint stand out?

Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
How long does external mastic last?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.

What else we do in Whitehouse
Signs you need external mastic in Whitehouse
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
Look out for any of the following:
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
Around Whitehouse, as everywhere, external mastic is only as good as the preparation behind it.

What the job involves on each surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
Why act early in Whitehouse
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Around Whitehouse, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

How the visit works
When we get to you, 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. Outside jobs in Whitehouse need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First, the joints are inspected and the access agreed.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Mention any tricky access

Related advice
Outside joints around Whitehouse
Whitehouse 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’s hard on movement joints and outside wall joints, especially on the side facing the sea. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
For jobs in and around Whitehouse, choosing the right material for each joint is as important as a tidy finish.
