How we handle window mastic in Edinburgh

The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you have black, perished sealant on frames and rushed sealant from a window installation, we can put it right, on aluminium frames, uPVC windows and composite doors alike.

In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Edinburgh, and in a tenement the outside of the building may be a shared repair.

Your job is guaranteed for a year, as with all our work.

What affects the cost of window mastic

For a quick quote, just ask. What matters most is:

  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • Whether the work is at height
  • Which sealant suits the joint

What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

What we need to know

There’s no need for technical detail. Just tell us:

  • A few pictures by email, if you can
  • Any access issues, like height or stairs
  • The address or postcode of the job
  • If someone has resealed it before

There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, email us at info@mrmastic.co.uk.

What we are called out for in Edinburgh

On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.

Keep an eye out for any of the following:

  • Rain getting in at the frame or under the sill
  • Mastic that has split away from the wall
  • A bead that does not match the frame
  • Old mastic that has gone black or come away

Schools such as Tollcross Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Before booking anyone

  • Whether VAT is included
  • What guarantee comes with the work
  • What happens if they find a problem under the old sealant
  • What the cure time is

10 questions to ask before booking

Edinburgh: your questions answered

How do repairs to the shared parts of a tenement in Edinburgh get organised?

It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.

Can you help a landlord with a rental near Haymarket station?

Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.

How long before the joint can be used?

Different products cure at different speeds, so follow the cure time we give you.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

Will resealing my frames help with draughts?

Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.

Do you cover Edinburgh?

Yes. We cover Edinburgh, as part of our work across South East England, London and Scotland. To book, email us at info@mrmastic.co.uk.

Is the new sealant paintable?

Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

What information do you need?

The location, the problem and the rough size of the job. Photos by email help too.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

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.

Frames and glazing around Edinburgh

Edinburgh is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls.

Rented homes near Haymarket station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. 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.

Edinburgh is in Scotland. We provide window mastic to homeowners, landlords and businesses in Edinburgh. Our area takes in 175 places across Edinburgh.

When it is not the sealant

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • Damp coming through the wall itself rather than the frame joint
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Rotten timber, which needs a joiner first

If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.

Where we work in Edinburgh

  • Aluminium frames
  • uPVC windows
  • Window sills
  • Composite doors
  • Patio & French doors
  • Timber windows & doors

Leave it or put it right?

If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. 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.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How the visit works

We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. 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. 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. The surfaces are cleaned and left dry.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. We tool the joint so water runs off, then clear up.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Tell us if parking is tricky
  • Mention any leaks or damp you’ve noticed
