External mastic in Carrington, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We work on render & cladding joints, concrete & block and façade panels, and common reasons people get in touch are movement joints filled with mortar instead of sealant and plants rooting in failed movement joints.
External sealant needs dry surfaces, so outdoor work around Carrington is planned around the weather. Tell us how to reach each wall, gutter and roofline.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

FAQs for Carrington
I let a flat near Gorebridge station. Can you help?
Yes, we work for landlords and agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Is Carrington within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
How long will you be here?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we’ll say how long yours will take.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Show decorators and builders where the movement joints are
- Keep high-pressure jets off the joints
- Never let anyone fill a movement joint with mortar
- Walk round the building once a year and look at the joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Landlords, agents and businesses in Carrington
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Letting agents and landlords in Carrington can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Leave it or put it right?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In an older home around Carrington, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.
Why book with us
- Every job guaranteed for a year
- A sealant colour to suit the surroundings
- We agree the colour with you first
- Any old sealant cut out fully, not covered over
What external mastic looks like in Carrington
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
For an older house near a landmark such as Carrington Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

- 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.

Advice
When to call us in Carrington
Every building moves. 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.
People normally contact us after spotting something like this:
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
Rented homes near Gorebridge station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
Before booking anyone
- Whether you can choose the colour
- Who does the work, and how experienced they are
- Are they insured?
- Whether they seal over old material or remove it

Surface by 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.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.
