Window & door mastic in Monymusk, Aberdeenshire
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Monymusk. Fully insured, ARBOMaster approved and guaranteed for a year.
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Window mastic in Monymusk, done properly
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on patio & French doors, composite doors and timber windows & doors, and common reasons people get in touch are gaps where the sill meets the wall and hard, cracked sealant around windows.
Outdoor sealant needs a dry surface, so window work around Monymusk is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

How the job changes by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Monymusk may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Common questions in Monymusk
Do you cover Monymusk for window mastic?
Yes. Our work covers the whole of Scotland, and Monymusk is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing.
What guarantee comes with window mastic in Monymusk?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you have insurance?
Yes, we’re fully insured.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Can new window sealant be painted?
Not normally, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.

When to call us in Monymusk
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
- White mastic on grey or black frames
- Old mastic that has gone black or come away
Around Monymusk, as everywhere, window mastic is only as good as the preparation behind it.

Windows and doors in Monymusk
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you live in an older home near St Mary's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why it’s worth doing now in Monymusk
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
