How we handle window mastic in Church Hill
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Common call-outs are for hard, cracked sealant around windows and cold air getting in at the frame edge, on composite doors, uPVC windows and patio & French doors.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Church Hill, and in a tenement the outside of the building may be a shared repair.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Church Hill, damp can travel a long way before it shows.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. For a tenement in Church Hill, 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.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Church Hill homes and the weather
Church Hill is within about 3 miles of 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional 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, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Aftercare tips
To keep the joints looking good and working properly:
- Don’t use solvent cleaners on the joint
- Paint up to the joint, not over it
- Check the mastic once a year
- Clean frames with a soft cloth and soapy water
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
FAQs for Church Hill
How do repairs to the shared parts of a tenement in Church Hill get organised?
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. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds don’t. Windows often belong to the individual flat, but it’s worth checking your deeds.
Is window mastic in a coastal place like Church Hill any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
What information do you need?
Let us know what needs doing and where. If we need more, we’ll ask.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Quotes for window mastic in Church Hill
The price is agreed before any work begins. It takes into account:
- The product the joint needs
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What to tell us for a quote
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- A few photos by email, if you can
- Whether it’s a home or a business
Every job is quoted individually, so the first step is telling us about yours. Just email us at info@mrmastic.co.uk with the details and send photos if you have them.
Do you need window mastic in Church Hill?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Any of these means the joints need attention:
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
Homes close to Churchill Theatre include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before booking anyone
- What happens if the job turns out different
- Whether the sealant suits the joint
- Whether you can choose the colour
- How the joint is cleaned and prepared
When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- A frame that has rotted at the joint
- Condensation trapped between the panes
- A sash or casement that won’t close properly
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
