Window & door mastic in Boddam, Aberdeenshire

About our window mastic in Boddam

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you are dealing with draughty joints inside around the window and old mastic that has gone black or come away, we can put it right.

In and around a place like Boddam, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.

Each job carries a 12-month guarantee, large or small.

What we are called out for in Boddam

Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.

People usually contact us when they notice something like this:

• Cold air getting in at the frame edge
• Old mastic that has gone black or come away
• Rain getting in at the frame or under the sill
• Untidy mastic left by window fitters

If you live in an older home near Parish Church Of Boddam, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Our hiring checklist

How it works

Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a handful of frames, longer for a whole house. Somewhere like Boddam 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.

1. First, we go round the frames with you and agree the list.
2. The old mastic is cut out and scraped back to clean surfaces.
3. Deep gaps get closed-cell backing rod to set the depth.
4. A flexible exterior sealant is applied in a colour to suit the frame.
5. We tool each bead neatly and check every joint is closed.

Preparing for the visit

• Tell us about access, such as stairs, a lift or high-level joints
• Plan for the work area to be out of bounds to pets and children
• Let us know about earlier repairs to the joints

• A door that needs adjusting, rehanging or new seals
• Penetrating damp from a failed cavity tray or render

If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Aftercare tips

Good habits help new joints last longer. A few tips:

• Clean frames with a soft cloth and soapy water
• Check the mastic once a year
• Keep solvents and bleach off the sealant
• Ventilate rooms so frames do not stay wet inside

Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.

Look out for the warning signs: 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.
