Landlord and commercial work in Howe Hill
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How we handle glazing silicone in Howe Hill
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for glass-to-glass joints that have split and conservatory leaks at frame and glazing joints, across conservatory frames, rooflights and glass-to-glass joints.
In a village or hamlet like Howe Hill, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee.

Questions from Howe Hill
Is there a guarantee on glazing silicone in Howe Hill?
All our work, in Howe Hill and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover Howe Hill for glazing silicone?
Yes. Our work covers London and the South East, and Howe Hill is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. The new bead cannot grip the old one, so we remove the old sealant and clean the joint.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can a conservatory leak be sealed?
That depends where the water is getting in. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Do not use a blade near the sealant
- Wipe the screen down after showering
- Ventilate the conservatory to cut condensation
- Clear the conservatory gutters regularly
Avoid scraping near the new silicone when you clean. Stick to a soft cloth.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.

Windows and doors in Howe Hill
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Stonor Park (about 3.2 miles south-east) nearby, there’s older building stock in the area around Howe Hill as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like Icknield Community College? Then larger buildings have plenty of frames, and the mastic around each one ages. Historic houses such as Stonor Park, about 3.2 miles south-east, show how far back building around Howe Hill goes.

What else we do in Howe Hill
What happens if it’s left?
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes, and we will tell you if that is not the case. Around Howe Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
