About our external mastic in Douglas Water
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 façade panels, render & cladding joints and joints between brick and frames, and the jobs we see most are joints pointed up with cement by mistake 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.
All our work comes with a 12-month guarantee, wherever you are in South Lanarkshire.

Landlord and commercial work in Douglas Water
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Douglas Water 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.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

What we cannot put right
A few problems are outside what sealant work can do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
Joints and surfaces we work on

What to tell us for a quote

- Whether it’s a home or a business
- The address or postcode of the job

- A few pictures by email, if you can
We quote each job on its own. Simply drop us a line at info@mrmastic.co.uk and describe the job, and photos are welcome.
Why it’s worth doing now in Douglas Water
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way and it means sorting access once. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why choose Mr Mastic in Douglas Water

External mastic in Douglas Water: local notes
Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Douglas Water, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. Letting a property close to Lanark station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What the job involves on each surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
