Should I try it myself first?
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.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Glazing silicone in Carndu
Glass and frames expand and contract differently, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We work on conservatory frames, glass-to-glass joints and shower screens, and common reasons people get in touch are water tracking down the inner face of the glass and stained, discoloured glazing silicone.
Mastic can only go onto a dry joint, so outside work in Carndu depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Each job carries a 12-month guarantee, large or small.

Surface by surface
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
FAQs for Carndu
Can you help a landlord with a rental near Stromeferry station?
Yes, we work for letting agents and landlords. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Is Carndu within the area you cover?
Yes, Carndu is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you reseal a frameless shower screen?
Yes. We remove the old silicone carefully, and the joints are cleaned and resealed.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
What guarantee do I get?
Our 12-month guarantee applies on all our work.
Can you fix a leaking conservatory?
It depends on the cause. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.
What affects the cost of glazing silicone
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- The size of the job
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Asking for a quote
To help us quote quickly, let us know:
- A few photos by email, if you can
- Roughly how big the job is
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
There’s no standard price list. Instead, we give you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
What glazing silicone looks like in Carndu
Carndu is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. 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.
If you let a flat or house near Stromeferry station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For an older house near a landmark such as St Duthuc's Roman Catholic Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Carndu is in Highland. Homes, rented property, offices and hotels in Carndu is covered for glazing silicone, old or new, large or small. The work is guaranteed for a year. Carndu is one of 253 towns and villages in Highland we cover for glazing silicone.
Every address in IV40 is covered for glazing silicone. Local streets include Helen Street, Princes Street and William Street, all of which we cover. Close by, we work in Bundalloch (1 mile north-east), Dornie (1 mile south-west), Auchtertyre (3 miles west), Inverinate (5 miles south-east) and Reraig (5 miles west). For island and remote addresses, the job takes a little more planning, so mention it when you ask for a quote.

What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant can’t fix:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Water coming through the roof rather than a sealant joint
- A frame that needs repairing or replacing
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Squeegee the shower screen after each use
- Clean glass with a mild cleaner and a soft cloth
- Ventilate the conservatory to cut condensation
- Keep conservatory gutters clear of leaves
On shower screens, wipe or squeegee after use and keep the room ventilated. It helps stop mould getting into the silicone.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we will find out which.
How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job normally takes anything from an hour or two to most of a day, depending on the size of the job, and we explain the cure time before we leave. Outdoor work around Carndu depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Preparing for the visit
