Window mastic for homes and businesses in Seafield
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for cracked sealant at the sill ends and water coming in at the bottom corners of a door, across patio & French doors, timber windows & doors and composite doors.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. Access is the first thing to plan for a job in Seafield.
A one-year guarantee comes with the work, just as it does everywhere we cover.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Seafield questions
How do repairs to the shared parts of a tenement in Seafield get organised?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Do you work for landlords with property near Edinburgh Waverley station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
What does window mastic cost?
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. We agree the price before any work begins.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What the job involves on each surface
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 look for the cause first.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
When it isn’t the sealant
Before booking, it’s worth knowing the limits:
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Where we work in Seafield
- Window sills
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Patio & French doors
- Composite doors
Looking after it afterwards
Aftercare is simple:
- Air rooms to keep condensation down around windows
- Keep paint off silicone joints
- Keep solvents and bleach off the sealant
- Keep paint and stain on wooden frames in good order
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Seafield, tell us the floor, how the door entry system works and where we can park nearby.
- Each frame is looked over and we agree which ones need resealing.
- 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.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks

When to call us in Seafield
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
Homes close to Restalrig Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- How the joint is cleaned and prepared
- Whether they’re fully insured
- What guarantee comes with the work
- Whether the sealant suits the joint
Windows and doors in Seafield
Seafield is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Whitefoord House (about 1.7 miles south-west) are a reminder that the area around Seafield has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Edinburgh Waverley station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Leith Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
