Glazing silicone in Aston
Across Aston, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. We work on shower screens, conservatory frames and rooflights, and common reasons people get in touch are new silicone smeared over old sealant and water running down inside the glass.
Mastic can only go onto a dry, clean joint, so window work in Aston is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

Windows and doors in Aston
Historic houses like Aston Bury (about 0.7 miles south) are a reminder that the area around Aston has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
For an older house near a landmark such as Parish Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Knebworth station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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. All the old material has to come out first.
How the visit works
The work is kept neat and contained to the area we’re working on. The job generally takes anything from an hour or two to most of a day, depending on the size of the job, and we tell you how long to leave it before we go. In a small place like Aston, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

When something else is needed
We will always be straight with you, so here’s what new sealant won’t do:
- Frames that have decayed or split
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Glass that needs replacing
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

What we are called out for in Aston
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Look out for any of the following:
- Failed sealant around rooflight glass
- Failed joints on frameless glass
- Shower screens leaking along the wall or tray
- Water running down inside the glass
If you look after a building such as Aston St Mary's Church of England Aided Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Different surfaces, different methods
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
Conservatory frames
Exposed frame joints wear with the weather. Renewed sealant keeps water out.
Aston: your questions answered
Is it worth replacing old sealant in an older home in Aston?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. The key is cutting all the old sealant out, as new sealant won’t bond to it.
Do you work for landlords with property near Knebworth station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you reseal glass shower screens?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do you seal glass balustrade bases?
We can, if the base joint is sealed. Photos help us see what’s there.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
