Glazing silicone in Cootham, done properly
Glazing silicone is a maintenance item. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. We are often asked to deal with leaks from the base of a shower screen and silicone pulling away from the glass, across glass-to-glass joints, glass-to-frame joints and conservatory frames.
Around Cootham, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, whatever its size.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Use gentle products around the joints
- Keep air moving in the conservatory
- Keep scrapers and blades away from the silicone
- Clear the conservatory gutters regularly
Follow the cure time we give you before the joints get wet. After that, clean glass with a mild cleaner.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the problem grows.
What glazing silicone looks like in Cootham
Historic houses like Parham House (about 1.1 miles west) are a reminder that the area around Cootham has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you look after a building such as Storrington Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Pulborough station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

FAQs for Cootham
Is Cootham within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Cootham for glazing silicone?
Yes. We work across London and the South East, and Cootham is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Do you seal glass balustrade bases?
Yes, where the base is finished with sealant. Photos help us see what’s there.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Why not top up the existing silicone?
Topping up is a common cause of leaks. We remove the old silicone, clean the joint and reseal.
How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work generally takes anything from an hour or two to most of a day, depending on the size of the job. In a small place like Cootham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- The finished joints are checked and, where it’s safe, tested with water.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Related advice
Do you need glazing silicone in Cootham?
Sealant laid over old sealant does not last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
Signs it’s time to call us include:
- Leaks where conservatory glass meets the frame
- New silicone smeared over old sealant
- Water escaping where a screen meets the wall
- Silicone pulling away from the glass
Parham House, about 1.1 miles west, is one of the historic houses in the wider area around Cootham, and older homes nearby need a sealant that suits their walls.

Landlords, agents and businesses in Cootham
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Why it’s worth doing now in Cootham
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames generally just need resealing, and we’ll tell you if that is not the case. Around Cootham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
