Glazing silicone in Howden
Glass and frames expand and contract differently, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. Typical jobs include shower screens leaking along the wall or tray and a quick top-up bead that didn’t last, on rooflights, shower screens and glass-to-glass joints.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Big or small, it’s backed by our one-year guarantee.

Surface by surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Howden: your questions answered
Is Howden within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Livingston North station?
Yes. We work for landlords and letting agents as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before any work starts.
What does glazing silicone cost?
It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk with a short description of the job.
Will resealing stop my conservatory leaking?
That depends where the water is getting in. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.
What do you need from me for a quote?
A short description and the location. If we need more, we will ask.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What affects the quote in Howden
Every job gets its own quote. These are the things that affect it:
- How easy the joints are to reach
- Working hours on commercial sites
- Mould in or behind the old joints
- Which sealant suits the joint
The cost depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- A few photos by email, if you can
- How many joints, rooms or windows are involved
Every job is quoted individually, so the first step is telling us about yours. Simply email us at info@mrmastic.co.uk and describe the job and send photos if you have them.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
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.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Look over the glazing joints once a year
- Check the gutters above the glazing for debris
- Wipe the screen down after showering
- Don’t use a blade near the sealant
Keep conservatory gutters clear so water doesn’t back up against the seals. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else, and we will tell you which.
Honest limits
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:
- Cracked or broken glass
- Water coming through the roof rather than a sealant joint
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Conservatory frames
- Rooflights
- Shower screens

Glazing silicone in Howden: local notes
Historic houses like Howden House (about 0.2 miles north-east) are a reminder that the area around Howden has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For site and facilities teams at buildings such as St. Margaret's Academy, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Livingston North station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

- Shower screens leaking along the wall or tray
- Leaking glazing joints on a rooflight

Questions to ask before booking
- Are they insured?
- The length of the guarantee
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most jobs from start to finish. Outside jobs in Howden need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
