About our glazing silicone in Headington Quarry
Across Headington Quarry, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. We are often asked to deal with silicone pulling away from the glass and shower screens leaking along the wall or tray, across rooflights, shower screens and glass-to-glass joints.
In smaller places like Headington Quarry, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Do you need glazing silicone in Headington Quarry?
Some conservatory leaks aren’t sealant at all: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
Most people get in touch when they notice one of these:
- Cracked silicone between glass panels
- Shower screens leaking along the wall or tray
- Conservatory leaks at frame and glazing joints
- Water tracking down the inner face of the glass
If you let a flat or house near Oxford station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Questions to ask before you book
- Is the old sealant removed completely?
- Is VAT in the price?
- How the joint is cleaned and prepared
- How much experience the applicator has
Landlords, agents and businesses in Headington Quarry
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured for the work.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Why deal with it now?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before you notice. Homes in smaller places like Headington Quarry 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.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Your questions about glazing silicone in Headington Quarry
Can you do glazing silicone in Headington Quarry?
Yes. Our work covers London and the South East, and Headington Quarry is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Can you help a landlord with a rental near Oxford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you replace glass?
No, our work is the silicone. Glass and sealed units need a glazier.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Which silicone is used for glass joints?
We use a neutral-cure glazing silicone that suits the glass and frame. Shower screens get anti-fungal silicone.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Glazing silicone in Headington Quarry: local notes
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. With historic houses such as Holywell Manor (about 2 miles west) nearby, there’s older building stock in the area around Headington Quarry 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.
Schools such as Headington Quarry Foundation Stage School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Holy Trinity Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Parking around Headington Quarry 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.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

- Rooflights

- Glass-to-frame joints
- Glass-to-glass joints

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Clean glass with a mild cleaner and a soft cloth
- Check the silicone on glass every year or so
- Squeegee the shower screen after each use
- Keep scrapers and blades away from the silicone
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the problem grows.
