FAQs for Colworth
Does the coastal weather in Colworth 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.
Can you help a landlord with a rental near Bognor Regis station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Is it possible to redo the silicone on a shower screen?
Yes, we do these often. The screen is resealed with anti-fungal silicone suited to bathrooms.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where do you work from?
Mr Mastic is based in Crawley. We cover Colworth and the rest of West Sussex.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Glazing silicone in Colworth
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We work on rooflights, glass balustrade bases and shower screens, and the jobs we see most are failed joints on frameless glass and leaks where conservatory glass meets the frame.
Mastic can only go onto a dry, clean joint, so window work in Colworth is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What else we do in Colworth
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What the job involves on each surface
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Signs you need glazing silicone in Colworth
Sunlight breaks sealant down, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
Common reasons people contact us are:
- Water escaping where a screen meets the wall
- Conservatory leaks at frame and glazing joints
- Sealant that was laid over old silicone and failed
- Mouldy sealant around glass panels
Goodwood House, about 4 miles north-west, is one of the historic houses in the wider area around Colworth.
Questions to ask before you book
- Which colour the sealant will be
- How hidden problems are handled
- Who does the work, and how experienced they are
- Whether VAT is included
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many joints need doing, and the area is left clean. In a small place like Colworth, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What glazing silicone looks like in Colworth
Colworth is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. With historic houses such as Goodwood House (about 4 miles north-west) nearby, there’s older building stock in the area around Colworth as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Bognor Regis station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Schools such as Bartons Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Why it’s worth doing now in Colworth
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Around Colworth, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
