External mastic in Hawick
For buildings in Hawick, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for moss and dirt in joints with no sealant left and rigid filler in a joint that should flex, across copings & trims, render & cladding joints and concrete & block.
Scottish weather is hard on outside joints, and a town like Hawick gets its share of wind and rain. A gap in a gutter joint, fascia trim or wall joint soon lets damp in.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

What affects the quote in Hawick
Call for a quick quote. What matters most is:
- The size of the job
- Access and height
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before we start.
Helping us quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- Whether it’s a home or a business
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. For a job in Hawick, tell us where the work is, how to get in and where to park. Outdoor jobs need a dry day, so they can move if the weather turns.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

Advice
What we are called out for in Hawick
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. The sealant in the movement joints takes that strain.
Look out for these signs:
- Plants rooting in failed movement joints
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
For site and facilities teams at buildings such as Hawick High School, its movement joints, gutters and trims need looking after like any other building’s.
Comparing quotes
- How the surfaces are prepared before sealing
- Are they insured?
- Whether all the old sealant comes out first
- Is VAT in the price?
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
If you manage several properties in or around Hawick, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Cracks in the bricks or render themselves, away from the joints
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.
Surfaces we seal
- Brickwork movement joints
- Concrete & block
- Façade panels
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
Different surfaces, different methods
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.

External mastic in Hawick: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Historic houses such as Harden, about 3.4 miles west, show how far back building around Hawick goes.
