About our glazing silicone in Colney Butts
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it, and if it’s something sealant can’t fix, we will tell you. We’re often asked to deal with black or yellowed silicone on glass joints and shower screens leaking along the wall or tray, across shower screens, rooflights and glass-to-frame joints.
In smaller places like Colney Butts, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Whatever the size of the job, it’s backed by our one-year guarantee.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Frames and glazing around Colney Butts
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as High Elms Manor (about 3.6 miles north) nearby, there’s older building stock in the area around Colney Butts as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Mary's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Watford Grammar School for Girls, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Watford High Street station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Leave it or put it right?
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. In an older home around Colney Butts, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for most jobs. A visit to Colney Butts is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Advice
Questions from Colney Butts
Can you help a landlord with a rental near Watford High Street station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is Colney Butts within the area you cover?

Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is it enough to run a bead over the old sealant?
New silicone won’t bond to old silicone and water gets between the layers. We cut out the old sealant first.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours, depending on how many joints need doing. We’ll tell you when we quote.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What does glazing silicone cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Do you seal glass balustrade bases?
Yes, where the base is finished with sealant. Send us photos and we’ll take a look when you call 0345 464 0079 or send us an email.
