About our glazing silicone in Longcot
Across Longcot, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. If you have silicone pulling away from the glass and new silicone smeared over old sealant, we can put it right.
Somewhere as small as Longcot, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, large or small.

Different surfaces, different methods
Conservatory frames
Frame joints face sun and rain all year. A fresh bead seals them again.
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
FAQs for Longcot
Do you cover smaller places like Longcot?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is glazing silicone in Longcot guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before we start.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can you replace a misted double-glazed unit?
No. A misted unit has failed inside, and a glazier needs to replace it.
Do you reseal glass shower screens?
We can. We remove the old silicone carefully, and the joints are cleaned and resealed.
How it works
On the day, we start by going over the job with you, so there are no surprises. 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. Somewhere as small as Longcot, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clean glass with a mild cleaner and a soft cloth
- Use gentle products around the joints
- Run a squeegee over the glass when you’re done
- Look over the glazing joints once a year
On shower screens, wipe or squeegee after use and let the room air. That slows mould growth on the bead.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.

What glazing silicone looks like in Longcot
With historic houses such as Buscot Park (about 4.1 miles north-west) nearby, there’s older building stock in the area around Longcot as well as newer homes. In older buildings, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Longcot and Fernham Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant will not do:

- Rotten or badly damaged frames
- Failed flashing around a conservatory
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Rooflights
- Glass balustrade bases
- Shower screens
- Glass-to-glass joints
- Conservatory frames
- Glass-to-frame joints
Why deal with it now?
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before it shows. Around Longcot, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
