About our window mastic in Greenhill
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on patio & French doors, timber windows & doors and uPVC windows, and the jobs we see most are hard, cracked sealant around windows and cracked sealant at the sill ends.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. In Greenhill, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
There’s a 12-month guarantee on every job, whatever its size.

Greenhill questions
Does the coastal weather in Greenhill affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How do repairs to the shared parts of a tenement in Greenhill get organised?
Shared parts of a tenement, such as the roof and outside walls, are usually 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.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
How do I get a quote for window mastic in Greenhill?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Keeping the joints in good condition
Looking after new joints is easy:
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
- Keep timber frames painted
- Keep paint off silicone joints
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Signs to watch for: 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.
What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of frames, longer for a whole house. For a tenement in Greenhill, 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.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Related advice
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. For landlords in Greenhill, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What the job involves on each surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Greenhill homes and the weather
Greenhill is within about 3 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 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.
For site and facilities teams at buildings such as Iain Tomlin School of Music, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Haymarket station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Morningside United Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
