Glazing Silicone in Portlethen
Glazing silicone for conservatories, rooflights, glass panels and shower screens for Portlethen, backed by a one-year guarantee. Call for a quick quote.
- Drips on the inside of a conservatory window
- A quick top-up bead that didn’t last
- Stained, discoloured glazing silicone
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Stick to mild cleaners on glass
- Avoid strong solvents on or near the sealant
- Squeegee the shower screen after each use
- Avoid scraping close to the bead
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
Glazing silicone in Portlethen, done properly
We work across Portlethen on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job. We work on glass balustrade bases, glass-to-glass joints and shower screens, and common reasons people get in touch are new silicone smeared over old sealant and rooflight joints letting water in.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
There’s a 12-month guarantee on every job.

Why deal with it now?
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Common questions in Portlethen
Is glazing silicone in a coastal place like Portlethen any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Portlethen station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Send us photos and we’ll take a look when you send an email to info@mrmastic.co.uk.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What we’re called out for in Portlethen
Glass and frames expand and contract with the temperature, and they do not move by the same amount. In time, the sealant splits or pulls away.
These are the problems we’re asked about most:
- Glass-to-glass joints that have split
- Drips on the inside of a conservatory window
- Sealant that was laid over old silicone and failed
- Water escaping where a screen meets the wall
If you live in an older home near Portlethen Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Around Portlethen, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

How we quote for glazing silicone
Jobs vary more than people expect. What affects the quote:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- The type of sealant required
- The size of the job
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
When you contact us, these details help:
- If someone has resealed it before
- Any access issues, like height or stairs
- The rough size of the job
- Whether it’s a home or a business
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved.
Windows and doors in Portlethen
Portlethen is close to 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. Aberdeen is known as the Granite City, and sealing against granite needs clean, sound edges and a sealant that suits stone.
Letting a property close to Portlethen station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Managing a site like Portlethen Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
