- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Paint up to the joint, not over it
- Look round the frames every year or so
- Keep timber frames painted
- Keep drainage slots and sill grooves clear
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Window mastic in West Craigs
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on patio & French doors, composite doors and window sills, and people most often call us about mastic that has split away from the wall and gaps where the sill meets the wall.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. In West Craigs, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What we do, step by step
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a morning for a couple of windows and a door for a typical job. Parking in city streets around West Craigs can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks

Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
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.

West Craigs: your questions answered
I let a flat near Edinburgh Gateway station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Does living near the coast affect window mastic in West Craigs?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can I paint over the new sealant?
Most silicone cannot be painted. Let us know beforehand, and we’ll use a paintable product where it suits.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you work in West Craigs?
Yes, we do. Our applicators work in West Craigs, and the service is the same as everywhere else.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
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. For landlords in West Craigs, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why us?
- Every job guaranteed for a year
- An ARBOMaster approved applicator
- We’re fully insured

What window mastic looks like in West Craigs
West Craigs is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Windows usually belong to the flat, but the title deeds have the final say.
Caroline Park, about 4 miles north-east, is one of the historic houses in the wider area around West Craigs. For landlords with property near Edinburgh Gateway station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Craigmount High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
