Dorchester Glazing Silicone
Glazing joints in Dorchester need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Rooflight joints letting water in
- Mouldy sealant around glass panels
- Sealant that was laid over old silicone and failed
Landlords, agents and businesses in Dorchester
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured for the work.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Glazing silicone in Dorchester, done properly
A frameless shower screen depends on its silicone. Leaks usually come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Typical jobs include conservatory leaks at frame and glazing joints and glazing silicone that has cracked or come away, on conservatory frames, rooflights and glass-to-glass joints.
Mastic can only go onto a dry, clean joint, so window work in Dorchester is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work is covered by a 12-month guarantee, wherever you are in Oxfordshire.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours, depending on how many joints need doing. In a small place like Dorchester, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
Getting a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand.
Advice
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Dorchester homes and the weather
With historic houses such as Clifton Hampden Manor (about 2 miles west) nearby, there’s older building stock in the area around Dorchester 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Dorchester St Birinus Church of England School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Dorchester Abbey, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Culham station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t use a blade near the sealant
- Use a gentle glass cleaner and a soft cloth
- Open vents or windows to let moisture out
- Check the silicone on glass every year or so
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the leak gets worse.
Your questions about glazing silicone in Dorchester
Do you work for landlords with property near Culham station?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is Dorchester in your area for glazing silicone?
Yes, Dorchester is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
What does glazing silicone cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What sealant do you use on glazing?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
