DIY versus a professional finish

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.

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.

Sand mastic in Edinburgh

On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. If you have wind and rain getting in round a sash window and patchy fillers round a sash window, we can help, on tenement windows, period & listed homes and stone surrounds alike.

Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. Whether you’re in a tenement flat or a house in Edinburgh, the joint between frame and wall is what keeps the weather out.

You get a one-year guarantee, the same in Edinburgh as everywhere else we work.

Sand mastic in Edinburgh: local notes

Edinburgh is within about 2 miles of 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 the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

If you live in an older home near St Cuthbert's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Haymarket station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Tollcross Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition

Looking after new joints is easy:

  • Inspect the joints round the windows every year or so
  • Ask a joiner to look at soft timber first
  • Find out about consent before window work on a listed home
  • Plan mastic work ahead of painting

Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.

Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.

How we quote for sand mastic

You’ll get a clear quote before any work starts. It takes into account:

  • The number of rooms or windows
  • How easy the joints are to reach
  • Any mould that needs treating
  • Whether old sealant or filler has to be cut out

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What we need to know

When you contact us, these details help:

  • If it’s domestic, commercial or a hotel
  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode
  • Any access issues, like height or stairs

Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

How it works

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows. For a tenement in Edinburgh, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

Getting ready for the visit

  • Mention any tricky access
  • Let us know about parking restrictions
  • Clear the area around the work

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Advice

What happens if it’s left?

Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

FAQs for Edinburgh

Does living near the coast affect sand mastic in Edinburgh?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Who arranges sealant work on the shared parts of a tenement in Edinburgh?

Shared parts of a tenement, such as the roof and outside walls, are normally repaired with the agreement of the owners, often through a property factor. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Your title deeds will say who owns the windows.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Can landlords and businesses book you?

Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.

Can I paint the new mastic?

Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.

Do you guarantee sand mastic work?

You get our 12-month guarantee to all our work.

Is there any odour?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Are you ARBOMaster approved?

Yes. We’re an ARBOMaster approved applicator.
