How we handle glazing silicone in Clothall

How the visit works
We keep the work tidy and contained to the joints we are treating. Expect the work to take a few hours, depending on how many joints need doing, and we explain the cure time before we leave. In a small place like Clothall, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on

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.
If you live in an older home near Church of St Mary, 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 Weston Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Why deal with it now?
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. Around Clothall, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Common problems we fix in Clothall
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.
Look out for these signs:
- Black or yellowed silicone on glass joints
- Sealant that was laid over old silicone and failed
- Shower screens leaking along the wall or tray
- Rooflight joints letting water in
For landlords with property near Baldock station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
Questions to ask before you book
- Is VAT in the price?
- How the joint is cleaned and prepared
- Which colour the sealant will be
- How long the guarantee is
Quotes for glazing silicone in Clothall
Every job gets its own quote. This is what makes a difference:
- Any working-time requirements on site
- The number of rooms or windows
- The type of sealant required
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
To make quoting easier, let us know:
- How we’d reach the joints
- A few pictures by email, if you can
- Roughly how big the job is
- The type of property

DIY versus a professional finish
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.
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.
