Glazing silicone for homes and businesses in Gravesend
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. Typical jobs include silicone pulling away from the glass and glass-to-glass joints that have split, on glass-to-glass joints, conservatory frames and rooflights.
In a village or hamlet like Gravesend, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Windows and doors in Gravesend
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Much Hadham Palace (about 3.6 miles south) are a reminder that the area around Gravesend has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Bishops Stortford station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Managing a site like Albury Church of England Voluntary Aided Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Your questions about glazing silicone in Gravesend

Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Can you match the sealant colour?

What should I tell you?
Tell us what needs doing and where. We will ask anything else we need to know.
Is the work guaranteed?
You get our one-year guarantee on all our work.
Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
Why not top up the existing silicone?
Silicone does not stick to silicone and water gets between the layers. The old bead always comes out first.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What the job involves on each surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Stick to mild cleaners on glass
- Keep scrapers and blades away from the silicone
- Look over the glazing joints once a year
- Wipe the screen down after showering
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
Don’t leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
How it works
At the end, we look at the finished work together. The work normally takes a few hours for most jobs, depending on how much there is to do. Somewhere as small as Gravesend, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
How to get a quote

Landlord and commercial work in Gravesend
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- A broken pane or roof panel
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Rotten or badly damaged frames
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal
- Glass-to-frame joints
- Glass balustrade bases
- Glass-to-glass joints
- Rooflights
- Conservatory frames
- Shower screens
Why it’s worth doing now in Gravesend
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. In a small place like Gravesend, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
