Common questions in Old Town
I let a flat near Eastbourne station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is glazing silicone in a coastal place like Old Town any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Glazing silicone for homes and businesses in Old Town
Across Old Town, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job. Typical jobs include split or lifting silicone on glass and water tracking down the inner face of the glass, across glass-to-glass joints, glass-to-frame joints and rooflights.
Around Old Town, 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, and any older timber or sash windows need a sealant that suits them.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

Letting agents often deal with us directly. Tell us the address, the job and how access works.
For anyone letting property in or around Old Town, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
What happens if it’s left?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Homes in smaller places like Old Town can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Windows and doors in Old Town
Old Town 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Eastbourne station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- We apply and tool the new silicone.

Before we arrive

What else we do in Old Town
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Act on drips or damp patches early
- Clear the conservatory gutters regularly
- Inspect the sealant on glazing annually
Clear the conservatory gutters regularly so water does not back up against the seals. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.
What affects the quote in Old Town

- How many rooms, windows or areas are involved
- The amount of work

The cost 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 any work starts, so you know where you stand.

When you call or email, these details help:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Any previous sealing or DIY work
Want a quote for glazing silicone? Please call 0345 464 0079 or drop us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Different surfaces, different methods
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
