How we handle window mastic in Duncrievie
Homes in Duncrievie have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on uPVC windows, composite doors and aluminium frames, and common reasons people get in touch are cold air getting in at the frame edge and white mastic on grey or black frames.
Mastic can only go onto a dry joint, so outside work in Duncrievie 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, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Common questions in Duncrievie
Is Duncrievie in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Duncrievie 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 Duncrievie?
All our work, in Duncrievie and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Do you work for letting agents?
Yes, often. Several properties can go on one quote.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
What information do you need?
Tell us what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Letting agents often deal with us directly. Tell us the address, the job and how access works.
Keeping the joints in good condition
Aftercare is simple:
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
- Keep paint off silicone joints
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames. Outside jobs in Duncrievie need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- 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.
- Finally we tidy up and check each joint.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

Duncrievie homes and the weather
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Arngask Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Around Duncrievie, as everywhere, window mastic is only as good as the preparation behind it.

Why it’s worth doing now in Duncrievie
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a place like Duncrievie, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
