The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on uPVC windows, aluminium frames and patio & French doors, and people most often call us about rushed sealant from a window installation and rain getting in at the frame or under the sill.

Leith is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.

The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Window mastic in Leith: local notes

Leith is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.

Schools such as Leith School of Art are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Ninians Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Leith is about 3 miles north-east of Edinburgh, in Edinburgh. Jobs in Leith get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Leith is one of 175 towns and villages in Edinburgh we cover.

What happens if it’s left?

Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Landlord and commercial work in Leith

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

What we’re called out for in Leith

Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.

Most people get in touch after spotting something like this:

  • Sealant in the wrong colour for the frame
  • Cracked or shrunken mastic around the frame
  • Draughty joints inside around the window
  • Water coming in at the bottom corners of a door

Rented homes near Edinburgh Waverley station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

FAQs for Leith

Is window mastic in a coastal place like Leith any different?

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

I let a flat near Edinburgh Waverley station. Can you help?

Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.

How long before the joint can be used?

Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Can you get sealant to suit coloured frames?

Normally, yes. Tell us the frame colour when you get in touch and we will use the nearest match.

Do you work on first-floor windows?

Normally, yes. Access is planned before any work starts.

Surface by surface

Timber windows & doors

Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.

Composite doors

If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.

What we do, step by step

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from an hour or two to a full day, depending on how many frames there are. Inside a flat in Leith, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Getting ready for the visit

  • Let us know about parking restrictions
  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive
