Horsham Glazing Silicone
Glazing joints in Horsham need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Failed sealant around rooflight glass
- Split or lifting silicone on glass
- Leaks from the base of a shower screen
How we handle glazing silicone in Horsham
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you have new silicone smeared over old sealant and water running down inside the glass, we can put it right, whatever the surface.
Beyond its homes, Horsham has shopfronts, offices and flats with plenty of frames and glazing, often on upper floors. A cracked joint on an upper floor can let water in long before anyone spots it.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Leave it or put it right?
You do not need new glazing because the sealant has gone. Sound glass and frames usually just need resealing. In flats, shops and offices in Horsham, a failed joint can let water into the unit below or behind a wall, where it’s often found late and is bigger to put right.
Instead of a standard rate, 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.
What you get with us
- Colour agreed with you before any work starts
- Sealant colour chosen to suit
- Trusted Arbo and Everbuild sealants
- Domestic, commercial and hotel work
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Avoid strong solvents on or near the sealant
- Inspect the sealant on glazing annually
- Check the gutters above the glazing for debris
- Open vents or windows to let moisture out
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Is Horsham in your area for glazing silicone?
Yes. Our work covers London and the South East, and Horsham is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Do you replace glass?
No. We renew the sealant. Glass and sealed units need a glazier.

Often, if the leak is at a sealant joint. We find where the water gets in first before any sealing.
How long will you be here?
Typically it takes a few hours for most jobs. Larger jobs naturally take longer, and we will say how long yours will take.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.

When to call us in Horsham
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Signs it’s time to call us include:
- Water tracking down the inner face of the glass
- Sealant that was laid over old silicone and failed
- Rooflight joints letting water in
- Conservatory leaks at frame and glazing joints
In the older streets around Hope Chapel, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before you book
- Whether you can choose the colour
- What preparation is included
- What guarantee comes with the work
- Who does the work, and how experienced they are
