Window mastic in Markethill, done properly
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you’re dealing with draughty joints inside around the window and white mastic on grey or black frames, we can put it right, on patio & French doors, window sills and uPVC windows alike.
Mastic can only go onto a dry joint, so outside work in Markethill depends on the weather. Let us know about access to every frame, including any upstairs.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. Somewhere like Markethill may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In a place like Markethill, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.
Why book with us
- Neat joints and a tidy finish
- Full insurance on every job
- Anti-fungal silicone where joints get wet

Yes. Our work covers the whole of Scotland, and Markethill is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Do you cover smaller places like Markethill?

What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
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 can do either or both.
Can you match the sealant to my frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Signs you need window mastic in Markethill
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That is what backing rod is for.
Keep an eye out for any of the following:
- Draughts coming in around windows and doors
- Hard, cracked sealant around windows
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
In and around Markethill, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether the sealant suits the joint
- How long to leave it before use
- The length of the guarantee

How the job changes by surface
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.
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Don’t aim a pressure washer at the joints
- Don’t use solvent cleaners on the joint
- Clear any debris from frame drain holes
- Paint up to the joint, not over it
Silicone cannot normally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Markethill homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near Abbey Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
