Glazing silicone in Crockerhill, done properly
Across Crockerhill, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. We’re often asked to deal with glass-to-glass joints that have split and drips on the inside of a conservatory window, on glass-to-glass joints, glass balustrade bases and conservatory frames.
Around Crockerhill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Big or small, you get the same 12-month guarantee.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many joints need doing. For a village or hamlet like Crockerhill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Mention any parking rules near the property

Advice
When to call us in Crockerhill
Sunlight breaks sealant down and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.
Look out for these signs:
- Cracked silicone between glass panels
- Water getting into a conservatory at the joints
- Stained, discoloured glazing silicone
- Water tracking down the inner face of the glass
If you look after a building such as The Henry Cort Community College, its window and door frames need their mastic kept sound, just like a home’s.

Crockerhill questions
Will you come out to Crockerhill?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Crockerhill affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you replace glass?
That’s not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
What guarantee do I get?
Every job comes with our 12-month guarantee, and we’re fully insured.
Are you insured?
Yes. Mr Mastic is fully insured.
What does glazing silicone cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Is there any odour?
Possibly a little. It fades as the sealant cures.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Crockerhill, along with the rest of our area.
Different surfaces, different methods
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. When it splits, water can get into the frame.
Frames and glazing around Crockerhill
Crockerhill is close to 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Fareham station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Landlords, agents and businesses in Crockerhill
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Landlords and letting agents in Crockerhill can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Why it’s worth doing now in Crockerhill
A leaking joint won’t fix itself. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. Where a wall is exposed, as many are in small places like Crockerhill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
