About our glazing silicone in Howwood
Glazing silicone is a maintenance item. Sun, rain and movement wear it down and cracked joints let water in. Resealing puts that right. We’re often asked to deal with black or yellowed silicone on glass joints and glazing silicone that has cracked or come away, on glass-to-glass joints, rooflights and glass-to-frame joints.
In and around a place like Howwood, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Honest limits
In fairness, some problems need a different trade:
- Frames that have decayed or split
- Water coming through the roof rather than a sealant joint
- A sealed unit that has misted inside

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Don’t leave a drip for the next storm
- Run a squeegee over the glass when you are done
- Keep harsh solvents off the silicone
- Check the silicone on glass every year or so
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.
Why it’s worth doing now in Howwood
You do not need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. In an older home around Howwood, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
