Glazing silicone in Renfrew, done properly
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. We’re often asked to deal with stained, discoloured glazing silicone and new silicone smeared over old sealant, across glass balustrade bases, conservatory frames and glass-to-glass joints.
Scottish weather is hard on window mastic, and a town like Renfrew gets its share of wind and rain. Frames on the side that takes the weather generally fail first.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

When something else is needed
We will not take on work that will not last, so here’s what sealant cannot put right:
- Water coming through the roof rather than a sealant joint
- Condensation trapped between two panes
- Glass that needs replacing
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Shower screens
- Glass-to-glass joints
- Glass-to-frame joints
- Conservatory frames
- Glass balustrade bases
- Rooflights
Keeping the joints in good condition
Aftercare is simple:
- Keep harsh solvents off the silicone
- Do not leave a drip for the next storm
- Squeegee the shower screen after each use
- Check the gutters above the glazing for debris
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we’ll tell you which.
Why act early in Renfrew
Topping up old silicone can look like a fix, but new silicone will not bond to old and water soon finds its way back. Cutting out and resealing properly lasts. In flats with a shared stair in Renfrew, a leak from a failed seal can affect the flat below too, which turns a small job into a bigger one.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

What glazing silicone looks like in Renfrew
With historic houses such as Pollok House (about 4 miles south-east) nearby, there’s older building stock in the area around Renfrew as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you let a flat or house near Hillington West station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For site and facilities teams at buildings such as Renfrew High School, larger buildings have plenty of frames, and the mastic around each one ages. Pollok House, about 4 miles south-east, is one of the historic houses in the wider area around Renfrew.
