About our glazing silicone in Sidlesham Common
Cracked, stained or lifting silicone on glass looks poor and can leak. We remove it without scratching the glass or frame before the new bead goes in. If you’re dealing with glazing silicone that has cracked or come away and black or yellowed silicone on glass joints, we can put it right, on glass-to-frame joints, conservatory frames and rooflights alike.
Around Sidlesham Common, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Water around a rooflight isn’t always the sealant. We find the cause first.

Before you book, it’s worth knowing the limits too:
- A broken pane or roof panel
- A sealed unit that has misted inside
- Leaks from the roof covering or flashing (a roofer’s job)

Questions from Sidlesham Common
Does the coastal weather in Sidlesham Common affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Sidlesham Common?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Sidlesham Common.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Is the work guaranteed?
Our 12-month guarantee applies to every job we do.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
The process
On the day, we look over the joints with you first. Surfaces next to the work are protected before we start. Most jobs take a few hours for most jobs. Somewhere as small as Sidlesham Common, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
How to prepare
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Why deal with it now?
A new conservatory roof is a big job. If the leak is a failed sealant joint, resealing is far simpler. If the roof is the problem, we’ll say so. Around Sidlesham Common, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

What affects the cost of glazing silicone
Your quote is based on your job. We look at:
- The amount of work
- How many areas need sealing
- Access and height
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
To help us quote quickly, let us know:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- Roughly how big the job is
- The address or postcode of the job
Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details, and pictures are welcome.
What glazing silicone looks like in Sidlesham Common
Sidlesham Common 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
