The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours, depending on how many joints need doing from start to finish. Somewhere like Selborne needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Advice
About our glazing silicone in Selborne
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on glass-to-frame joints, shower screens and glass-to-glass joints, and common reasons people get in touch are a quick top-up bead that didn’t last and stained, discoloured glazing silicone.
In a village or hamlet like Selborne, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Every job is covered by our 12-month guarantee.

Surface by surface
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.
Selborne: your questions answered
Is Selborne within the area you cover?
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.
Can you help a landlord with a rental near Alton station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Where is Mr Mastic based?
We work from Crawley. We cover Selborne and the rest of Hampshire, along with the rest of our area.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for most jobs. We will give you a better idea when we quote.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you reseal a frameless shower screen?
We can. We remove the old silicone carefully before cleaning and resealing.
Windows and doors in Selborne
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.
If you look after a building such as Selborne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Alton station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What we are called out for in Selborne
UV light ages silicone and roof joints get the most sun. It goes brittle, cracks and stops sticking on the glass.
Signs it’s time to call us include:
- A quick top-up bead that didn’t last
- Drips on the inside of a conservatory window
- Conservatory leaks at frame and glazing joints
- Leaks from the base of a shower screen
For an older house near a landmark such as Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- When the joint can take water or movement
- How much experience the applicator has
- The length of the guarantee
- What product goes in the joint
Landlord and commercial work in Selborne
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What affects the quote in Selborne
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- The number of rooms or windows
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
When you contact us, it’s useful to know:
- Whether it has been sealed before
- What’s wrong with the joints now
- Whether it’s a home or a business
- Roughly how big the job is
For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. We will send you a clear quote before any work starts.
Why deal with it now?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Where a wall is exposed, as many are in small places like Selborne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why us?
- You choose the colour before work begins
- A 12-month guarantee on all work
