Glazing & conservatory sealant in Fernhill, Surrey
Our applicators work in Fernhill on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Sealant that was laid over old silicone and failed
- Glazing silicone that has cracked or come away
- Shower screens leaking along the wall or tray
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Glazing silicone for homes and businesses in Fernhill
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. If you have rooflight joints letting water in and water tracking down the inner face of the glass, we can put it right, on glass-to-frame joints, conservatory frames and shower screens alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Fernhill is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You get a one-year guarantee, the same in Fernhill as everywhere else we work.

Landlord and commercial work in Fernhill
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Replacing a conservatory roof is major work. If the leak is a failed sealant joint renewing the joint is the simpler fix. If the roof is the problem, we’ll say so. In a small place like Fernhill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Common problems we fix in Fernhill
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
Signs it’s time to call us include:
- New silicone smeared over old sealant
- Leaking glazing joints on a rooflight
- Water getting into a conservatory at the joints
- Black or yellowed silicone on glass joints
For site and facilities teams at buildings such as Oakwood School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- How long the guarantee is
- What product goes in the joint

Windows and doors in Fernhill
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Gatwick Airport station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you live in an older home near Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
