FAQs for Ossemsley
Will you come out to Ossemsley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Ossemsley affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you guarantee glazing sealant work?
All our work has a 12-month guarantee, and we are fully insured.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We find where the water gets in first, so you know what you’re paying for.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Glazing silicone for homes and businesses in Ossemsley
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. If you have split or lifting silicone on glass and failed joints on frameless glass, we can help, on glass-to-glass joints, glass-to-frame joints and shower screens alike.
In a village or hamlet like Ossemsley, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we’re called out for in Ossemsley
The wrong sealant is a common cause. Some products don’t bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
Common reasons people contact us include:
- Failed sealant around rooflight glass
- Water getting into a conservatory at the joints
- Drips on the inside of a conservatory window
- New silicone smeared over old sealant
For an older house near a landmark such as St John, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Advice
What the job involves on each surface
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Windows and doors in Ossemsley
Ossemsley is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. 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.
If you let a flat or house near New Milton station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Schools such as Ballard School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Ossemsley
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. In a small place like Ossemsley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

What affects the cost of glazing silicone
Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- How many areas need sealing
- Whether there’s mould to deal with
- How easy the joints are to reach
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How we’d reach the joints
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Water coming through the roof rather than a sealant joint
- A frame that needs repairing or replacing
- Structural problems with a conservatory roof
