Glazing silicone in Hawley, done properly
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we’ll tell you. We work on conservatory frames, rooflights and glass-to-glass joints, and common reasons people get in touch are leaks from the base of a shower screen and leaking glazing joints on a rooflight.
Houses in smaller places like Hawley can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Surface by surface
Rooflights
Rooflight glazing joints are cut out and renewed. If the leak is from the roof around it, a roofer needs to look.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
Frames and glazing around Hawley
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.
Rented homes near Blackwater station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you live in an older home near Holy Trinity Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Hawley Primary School, the mastic around its windows and doors needs looking after like any other building’s.

We work in homes and buildings around Mr Bumble pub, Fernhill School and Language College and Royal Military Academy Library and the streets around them. Hawley has its own railway station: Blackwater station. Other landmarks nearby include Staff College Museum (1.6 miles north-east) and Frimley Park Hospital (1.7 miles east). Open spaces near Hawley include Wildmoor Heath and Horseshoe Lake.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Clean glass with a mild cleaner and a soft cloth
- Squeegee the shower screen after each use
- Look over the glazing joints once a year
- Avoid strong solvents on or near the sealant
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below long before you see it.
Hawley: your questions answered
Is Hawley 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.
Can you help a landlord with a rental near Blackwater station?
Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Will resealing stop my conservatory leaking?
In many cases, as long as sealant is the cause. We find where the water gets in first before any sealing.
How long will you be here?
Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Your quote will say how long we expect yours to take.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Where do you work from?
We work from Crawley. We cover Hawley and the rest of Hampshire.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours, depending on how many joints need doing from start to finish.

Related advice
Why deal with it now?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In a smaller place like Hawley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
