Glazing silicone in Holbury
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. Common call-outs are for water escaping where a screen meets the wall and water getting into a conservatory at the joints, on glass-to-glass joints, shower screens and glass balustrade bases.
Around Holbury, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of glazing silicone
Your quote is based on your job. We take into account:
- The old material and how stubborn it is
- Working hours on commercial sites
- How many rooms, windows or areas are involved

When to call us in Holbury
Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.
If you can see any of these, it’s time to have the joints looked at:
- Stained, discoloured glazing silicone
- Rooflight joints letting water in
- Leaks where conservatory glass meets the frame
- Water running down inside the glass
For site and facilities teams at buildings such as Cadland Primary School, its window and door frames need their mastic kept sound, just like a home’s.

FAQs for Holbury
Is glazing silicone in a coastal place like Holbury any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
I let a flat near Netley station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
How long does glazing silicone take?
A typical job takes a few hours, depending on how many joints need doing, including the preparation. Your quote will say how long we expect yours to take.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Holbury.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from an hour or two to most of a day, depending on the size of the job. A visit to Holbury is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

What glazing silicone looks like in Holbury
Holbury is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on glazing joints and frame seals, especially on the side facing the sea. With historic houses such as Beaulieu Palace House (about 2.9 miles west) nearby, there’s older building stock in the area around Holbury 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.
Historic houses such as Beaulieu Palace House, about 2.9 miles west, show how far back building around Holbury goes, and older homes nearby need a sealant that suits their walls. If you let a flat or house near Netley station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why it’s worth doing now in Holbury
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Homes in smaller places like Holbury can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
