How to look after the new joints
Good habits help new joints last longer. Our tips:
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Avoid blasting the frames with a pressure washer
- Wipe condensation off the frames
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes most of a day for a typical house, less for a few frames. Somewhere like Cupar may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Tell us if parking is tricky
- Move anything stored near the joints
- Mention if the joints have been sealed before

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why book with us
- We never seal over old sealant
- Anti-fungal sanitary silicone in wet areas

What window mastic looks like in Cupar
Historic houses like Hill of Tarvit (about 1.6 miles south) are a reminder that the area around Cupar has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Letting a property close to Cupar station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Old And St Michael Of Tarvit Parish Church tower and nave, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What we are called out for in Cupar
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Common reasons people contact us are:
- Gaps between the frame and the inside reveal
- A bead that doesn’t match the frame
- Mastic that’s falling out in pieces
- Rain getting in at the frame or under the sill
Schools such as Bell Baxter High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Who does the work, and how experienced they are

- What happens if the job turns out different
- Is VAT in the price?
