Glazing silicone for homes and businesses in Kidlington
Glass and frames expand and contract differently, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. We work on shower screens, glass balustrade bases and conservatory frames, and common reasons people get in touch are glazing silicone that has cracked or come away and water escaping where a screen meets the wall.
Houses in smaller places like Kidlington can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
Whatever the size of the job, you get the same one-year guarantee in Kidlington and across Oxfordshire.

Is the work guaranteed?

Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Where is Mr Mastic based?

Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone suited to bathrooms.
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.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Glazing silicone in Kidlington: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Blenheim Palace (about 3.5 miles north-west) nearby, there’s older building stock in the area around Kidlington as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Oxford Parkway station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as St Thomas More Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most jobs from start to finish. A visit to Kidlington is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
How to prepare
- Clear the area around the work
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Other services in Kidlington
Surface by surface
Glass balustrade bases
The base joint is cut out and resealed. We don’t install or replace glass.
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
What happens if it’s left?
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. Around Kidlington, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- A roof that has moved or dropped
- Frames that have decayed or split
- Condensation trapped between two panes
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Shower screens
- Conservatory frames
- Rooflights
- Glass-to-frame joints
- Glass balustrade bases
- Glass-to-glass joints
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Avoid scraping close to the bead
- Open vents or windows to let moisture out
- Use a gentle glass cleaner and a soft cloth
- Use gentle products around the joints
Avoid scraping near the new silicone when cleaning the glass. A soft cloth or sponge is best.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
