Glazing silicone in Berwick
Cracked, stained or lifting silicone on glass spoils the look and lets water in. We remove it without scratching the glass or frame and reseal the joint. If you have a quick top-up bead that didn’t last and rooflight joints letting water in, we can help.
Around Berwick, 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.
You get a 12-month guarantee, the same in Berwick as everywhere else we work.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Landlord and commercial work in Berwick
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Berwick homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Charleston Farmhouse (about 2.2 miles west) nearby, there’s older building stock in the area around Berwick 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.
For an older house near a landmark such as The Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Berwick (Sussex) station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

How the job changes by surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Why act early in Berwick
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone and water soon finds its way back. A proper reseal is the lasting answer. In a small place like Berwick, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
