How we handle glazing silicone in Bernards Heath
We do not replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that’s often where the water gets in. Typical jobs include water getting into a conservatory at the joints and leaking glazing joints on a rooflight, across glass-to-glass joints, conservatory frames and glass-to-frame joints.
In smaller places like Bernards Heath, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
All of our work is guaranteed for twelve months.

Questions from Bernards Heath
Will you come out to Bernards Heath?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near St Albans station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you replace a misted double-glazed unit?
No. A misted unit has failed inside and needs replacing by a glazier.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will resealing stop my conservatory leaking?
It depends on the cause. Sealant joints we can renew but roof and panel problems need another trade.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
Why act early in Bernards Heath
A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. In a smaller place like Bernards Heath, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.

How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on how many joints need doing for a typical job. In a smaller place like Bernards Heath, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Clear the area around the work

Advice
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep air moving in the conservatory
- Clean glass with a mild cleaner and a soft cloth
- Use gentle products around the joints
- Check the silicone on glass every year or so
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we’ll find out which.

Frames and glazing around Bernards Heath
Historic houses like Batchwood Hall (about 1 mile west) are a reminder that the area around Bernards Heath has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near St Albans station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Church of St Saviour, the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like Garden Fields Junior Mixed and Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. We reseal them with a sealant suited to the frame.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
