Window & door mastic in Eastfield, Edinburgh
We cover Eastfield for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
Aftercare tips
After the cure time, these simple habits help:
- Clean frames with a soft cloth and soapy water
- Keep solvents and bleach off the sealant
- Keep jet washers away from the mastic
- Keep paint and stain on wooden frames in good order
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Window mastic in Eastfield, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. Common call-outs are for whistling draughts around closed windows and leaking joints at the ends of sills, across aluminium frames, patio & French doors and uPVC windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What window mastic looks like in Eastfield
Eastfield 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. The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. For listed homes and conservation areas, check with the council before changing how windows or walls look.
For an older house near a landmark such as St Philip's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Loretto School, larger buildings have plenty of frames, and the mastic around each one ages.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are and we leave things clean and tidy. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

How the job changes by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We will point out any rot we find, as that’s a job for a joiner.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In an older home around Eastfield, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost 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, so you know where you stand.

- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
- Mastic that is falling out in pieces

Questions from Eastfield
Do you cover smaller places like Eastfield?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Eastfield affect outside sealant?
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.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can new window sealant be painted?
Silicone generally won’t take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
Do you have insurance?
Yes. We are fully insured.
