Glazing Silicone in Porchfield
Glazing joints in Porchfield need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Sealant that was laid over old silicone and failed
- Failed joints on frameless glass
- Mouldy sealant around glass panels
What the job involves on each surface
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Glazing silicone for homes and businesses in Porchfield
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. Typical jobs include glazing silicone that has cracked or come away and water escaping where a screen meets the wall, on glass-to-frame joints, rooflights and conservatory frames.
Homes in small places like Porchfield often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

Common problems we fix in Porchfield
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip on the glass.
These are the problems we’re asked about most:
- Glass-to-glass joints that have split
- Water tracking down the inner face of the glass
- Mouldy sealant around glass panels
- Conservatory leaks at frame and glazing joints
Historic houses such as Swainston Manor, about 2.2 miles south, show how far back building around Porchfield goes, and older homes nearby need a sealant that suits their walls.
Before you book anyone
- How the surfaces are prepared before sealing
- How much experience the applicator has
- Whether the sealant suits the joint
- Is the old sealant removed completely?
What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from an hour or two to most of a day, depending on the size of the job, and we tell you how long to leave it before we go. For a village or hamlet like Porchfield, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before

What affects the quote in Porchfield

- The number and length of the joints
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- The type of property
- Roughly how big the job is
- Any access issues, like height or stairs
We quote each job on its own. Simply ring 0345 464 0079 or email us and describe the job.
Why act early in Porchfield
A new conservatory roof is a big job. Where the water is getting in through sealant, resealing is far simpler. If the roof is the problem, we will say so. Around Porchfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the 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.

What glazing silicone looks like in Porchfield
Porchfield is close to 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. 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.
In and around Porchfield, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.
