Window mastic in Lauriston, done properly
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for untidy mastic left by window fitters and leaking joints at the ends of sills, on patio & French doors, uPVC windows and composite doors.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which usually means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Every job comes with our one-year guarantee.

Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
What else we do in Lauriston
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. 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.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- Rated 4.9 stars on Google
- Any old sealant cut out fully, not covered over
- Neat joints and a tidy finish

Window mastic in Lauriston: local notes
Lauriston 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. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. For listed homes and conservation areas, check with the council before changing how windows or walls look.
In the older streets around Lauriston Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. 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. Managing a site like Edinburgh School of Architecture and Landscape Architecture? Then larger buildings have plenty of frames, and the mastic around each one ages.

Lauriston questions
Who arranges sealant work on the shared parts of a tenement in Lauriston?
Most tenements arrange shared repairs through the owners or a property factor. 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.
I let a flat near Edinburgh Waverley station. Can you help?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can I add another job to the visit?
Yes. Just list everything you need.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- The product the joint needs
- How many areas need sealing
- Access and height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- A few pictures by email, if you can
- The type of property
- The rough size of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Do not paint over the silicone
- Ventilate rooms so frames do not stay wet inside
- Check the mastic once a year
- Don’t aim a pressure washer at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
How the visit works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. For a tenement in Lauriston, 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.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
