About our window mastic in Douglastown
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you’re dealing with draughty joints inside around the window and gaps left after new windows were fitted, we can help, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Douglastown depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Our work is backed for twelve months, in Douglastown and everywhere else we cover.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When something else is needed
To be straight with you, some problems need a different trade:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A sash or casement that will not close properly
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Window sills
- Composite doors
- uPVC windows
- Patio & French doors
- Aluminium frames
- Timber windows & doors
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Common problems we fix in Douglastown
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.
It’s worth asking for a quote if you see:
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
Historic houses such as Glamis Castle, about 2 miles west, show how far back building around Douglastown goes, and older homes nearby need a sealant that suits their walls.

Window mastic in Douglastown: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Historic houses like Glamis Castle (about 2 miles west) are a reminder that the area around Douglastown has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Around Douglastown, as everywhere, window mastic is only as good as the preparation behind it.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of rooms or windows
- The size of the job
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- The type of property
- Any access issues, like height or stairs
- Where the property is
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, send an email to info@mrmastic.co.uk.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use gentle cleaners on frames and sealant
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
- Walk round the house once a year and look at the joints
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a few frames, or a day or more for a whole house, and the area is left clean. For a place like Douglastown, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
