- Water running down inside the glass
- Leaks where conservatory glass meets the frame
- Silicone pulling away from the glass
How to look after the new joints
A little care helps the new joints last. Our advice:
- Look over the glazing joints once a year
- Open vents or windows to let moisture out
- Clean glass with a mild cleaner and a soft cloth
- Act on drips or damp patches early
Don’t use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
Glazing silicone in Farnham, done properly
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. We remove it without scratching the glass or frame before the new bead goes in. If you have water tracking down the inner face of the glass and rooflight joints letting water in, we can help.
Mastic can only go onto a dry, clean joint, so window work in Farnham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old, and the leak normally returns. Cutting out and resealing properly lasts. In a small place like Farnham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

What affects the quote in Farnham
We do not publish a price list, because no two jobs are the same. What we look at:
- Whether there’s mould to deal with
- The product the joint needs
- Working hours on commercial sites
- The old material and how stubborn it is
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for most jobs from start to finish.

Advice
Landlords, agents and businesses in Farnham
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
When to call us in Farnham
Sealant laid over old sealant doesn’t last. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Keep an eye out for these signs:
- Glass-to-glass joints that have split
- Conservatory leaks at frame and glazing joints
- Water escaping where a screen meets the wall
- Water running down inside the glass
For landlords with property near Stansted Mountfitchet station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Frames and glazing around Farnham
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Much Hadham Palace (about 4.2 miles south-west) are a reminder that the area around Farnham has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Mary the Virgin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Farnham Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
