Can I do it myself?
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.
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.
Keeping the joints in good condition
Aftercare is simple:
- Ventilate rooms so frames don’t stay wet inside
- Check the mastic once a year
- Don’t paint over the silicone
- Keep jet washers away from the mastic
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work normally takes a morning for a couple of windows and a door. In a city area like Blackhall, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

What else we do in Blackhall
How the job changes by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
FAQs for Blackhall
Do you work for landlords with property near Haymarket station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
How is work on the outside of a tenement in Blackhall generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you have sealant for grey or black windows?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. For landlords in Blackhall, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- A sash or casement that won’t close properly
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

Window mastic in Blackhall: local notes
Blackhall is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Schools such as The Mary Erskine School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Columba's Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Haymarket station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
