Easterhouse External Mastic
External mastic in Easterhouse from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Sealant that has lost its bond to the brick or render
- Weathered mastic that no longer stretches
- Cracked joints where brick meets render or frames
What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Easterhouse need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- 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
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

External mastic in Easterhouse, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you’re dealing with hard, crazed mastic that has stopped moving and panel joints letting water in, we can put it right, on concrete & block, render & cladding joints and façade panels alike.
External sealant needs dry surfaces, so outdoor work around Easterhouse is planned around the weather. Let us know about access to every wall and roofline.
We stand behind the work with a 12-month guarantee.

Different surfaces, different methods
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Signs you need external mastic in Easterhouse
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.
The problems people normally mention when they call are:
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
In the older streets around Saint Benedict's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before booking
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- What guarantee comes with the work

Walls and rooflines in Easterhouse
Easterhouse is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For site and facilities teams at buildings such as St. Leonard's Secondary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Easterhouse station, split movement joints are easy to miss on a rental until damp shows inside.

Can you help a landlord with a rental near Easterhouse station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll tell you when we quote.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.

Yes, we’re fully insured.

Work for landlords, hotels and businesses
Landlords and agents in Easterhouse can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In an older home around Easterhouse, damp from a failed joint can get into timber and plaster.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Why book with us

- A choice of colours where the product allows

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What sealant work cannot fix
New sealant can’t fix everything, and we will tell you before work begins. It will not solve:
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.
