Glazing & conservatory sealant in Forfar, Angus
Glazing joints in Forfar need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Glazing silicone for homes and businesses in Forfar
Glass replacement is not something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints, which is where many leaks start. We work on rooflights, glass-to-frame joints and shower screens, and common reasons people get in touch are drips on the inside of a conservatory window and leaks where conservatory glass meets the frame.
Scottish weather is hard on window mastic, and a town like Forfar gets its share of wind and rain. The windows facing the weather are generally the first to leak, so it’s worth checking them all.
Our work is backed for twelve months.

Signs you need glazing silicone in Forfar
Some conservatory leaks aren’t sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
It’s worth asking for a quote if you see:
- New silicone smeared over old sealant
- Glass-to-glass joints that have split
- Glazing silicone that has cracked or come away
- Water escaping where a screen meets the wall
Schools such as Forfar Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- How the colour is chosen
- How the joint is cleaned and prepared
- How hidden problems are handled
- Whether all the old sealant comes out first
Why act early in Forfar
Resealing can’t fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. In flats with a shared stair in Forfar, a leak from a failed seal can affect the flat below too, and that’s much harder to put right.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Colour agreed with you before we start
- Old sealant always removed completely
- Homes, businesses and hotels
The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many joints need doing. A visit in Forfar needs three things planned: access, parking and where the work is. Outdoor jobs need a dry day, so they can move if the weather turns.
- First, we check where the water gets in.
- 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.
Getting ready for the visit
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Windows and doors in Forfar
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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 an older house near a landmark such as Forfar Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Sealant isn’t the answer to every problem, and we will tell you before we start. It will not solve:
- A roof that has moved or dropped
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Failed flashing around a conservatory

- Shower screens

Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep conservatory gutters clear of leaves
- Keep air moving in the conservatory
- Use gentle products around the joints
- Use a gentle glass cleaner and a soft cloth
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
