How we handle glazing silicone in Whithorn
Sealant on glazing doesn’t last for ever. Weather and movement take their toll and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on rooflights, shower screens and glass-to-glass joints, and people most often call us about sealant that was laid over old silicone and failed and water escaping where a screen meets the wall.
Mastic can only go onto a dry joint, so outside work in Whithorn depends on the weather. Tell us about access to all the windows and doors, upstairs included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

When it is not the sealant

Aftercare tips
After the cure time, these simple habits help:
- Use a gentle glass cleaner and a soft cloth
- Get a new leak looked at quickly
- Do not use a blade near the sealant
- Inspect the sealant on glazing annually
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with straight away.
Windows and doors in Whithorn
Whithorn is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on glazing joints and frame seals, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Whithorn, as everywhere, glazing silicone is only as good as the preparation behind it. If you live in an older home near St Martin and St Ninian Catholic Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Should I try it myself first?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What the job involves on each surface
Rooflights
Water around a rooflight is not always the sealant. We find the cause first.
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
What affects the cost of glazing silicone
Every job gets its own quote. This is what makes a difference:
- The size of the job
- Which sealant suits the joint
- The old material and how stubborn it is
- How many areas need sealing
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- A few pictures by email, if you can
- The type of property
- What’s wrong with the joints now
- Any previous sealing or DIY work
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, drop us a line at info@mrmastic.co.uk.

Will you come out to Whithorn?

Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.

What should I tell you?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Is it possible to redo the silicone on a shower screen?
We can. The old bead comes off without marking the glass before cleaning and resealing.

Why deal with it now?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Around Whithorn, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

How it works
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work normally takes a few hours, depending on how many joints need doing. Outdoor work around Whithorn depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
