Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Riddrie: your questions answered
How is work on the outside of a tenement in Riddrie normally arranged?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.
Do you work for landlords with property near Alexandra Parade station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check the mastic once a year
- Clear any debris from frame drain holes
- Wipe condensation off the frames
- Keep paint and stain on wooden frames in good order
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
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. If you notice one, it’s time to get the joint looked at.
