What happens on the day
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on how many joints need doing. Somewhere as small as Holwellbury, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

How we handle glazing silicone in Holwellbury
Glazing silicone is a maintenance item. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. If you have leaks from the base of a shower screen and black or yellowed silicone on glass joints, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Holwellbury is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
Topping up old silicone can look like a fix, but new silicone will not bond to old and water soon finds its way back. A proper reseal is the lasting answer. Where a wall is exposed, as many are in small places like Holwellbury, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Signs you need glazing silicone in Holwellbury
Some conservatory leaks aren’t sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That’s why we trace the leak first.
The most common problems we see are:
- Drips on the inside of a conservatory window
- Glass-to-glass joints that have split
- Leaks from the base of a shower screen
- Conservatory leaks at frame and glazing joints
For site and facilities teams at buildings such as Derwent Lower School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include

- Who turns up on the day

- How the joint is cleaned and prepared
What the job involves on each surface
Rooflights
Rooflight glazing joints are cut out and renewed. If the leak is from the roof around it, a roofer needs to look.
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- A roof that has moved or dropped
- A frame that needs repairing or replacing
- Condensation trapped between two panes
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal
- Glass-to-glass joints

Windows and doors in Holwellbury
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Arlesey station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around Church of St Peter (C of E) at Corner with Holwell Road, the joint between an old wall and a newer frame is normally the first place rain gets in.
