Glazing silicone in Headington
A frameless shower screen depends on its silicone. Leaks generally come from the wall joint or the tray joint, and we reseal both. Common call-outs are for failed joints on frameless glass and stained, discoloured glazing silicone, across glass-to-frame joints, glass-to-glass joints and glass balustrade bases.
Homes around Headington range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What we are called out for in Headington
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
It’s worth asking for a quote if you see:
- Glass-to-glass joints that have split
- Water running down inside the glass
- Silicone pulling away from the glass
- Rooflight joints letting water in
Rented homes near Oxford station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
What to look for in a quote
- How much experience the applicator has
- Whether they’re fully insured
- What happens if the job turns out different
- Which colour the sealant will be

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What affects the cost of glazing silicone
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- The amount of work
- Whether the work is at height
- The product the joint needs
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
What to tell us when you ask for a quote:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- How we’d reach the joints
- The address or postcode of the job
To get a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before any work starts.
Why it’s worth doing now in Headington
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before you notice. In an older home around Headington, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. The new bead cannot grip the old one so we take it all out and start clean.
Do you fit new glass or sealed units?
Glass replacement is not our trade. We reseal the joints around it, and we will tell you if a unit looks like it has failed.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
What glazing silicone looks like in Headington
With historic houses such as Holywell Manor (about 1.6 miles west) nearby, there’s older building stock in the area around Headington as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Andrew's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as St Andrew's Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How the visit works
Before we leave, we go over the finished joints with you. The work normally takes anything from an hour or two to most of a day, depending on the size of the job, depending on how much there is to do. Parking around Headington is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
