Glazing silicone in South Malling, done properly
Glass replacement is not something we do, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that is often where the water gets in. We work on conservatory frames, glass-to-glass joints and glass balustrade bases, and the jobs we see most are leaking glazing joints on a rooflight and split or lifting silicone on glass.
Around South Malling, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.

Your questions about glazing silicone in South Malling

Do you cover smaller places like South Malling?

Will resealing stop my conservatory leaking?
It depends on the cause. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
Is balustrade sealant something you do?
Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Frames and glazing around South Malling
Historic houses like Anne of Cleves House (about 0.8 miles south-west) are a reminder that the area around South Malling has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is 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.
If you live in an older home near Church of St Michael, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Lewes station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. Parking around South Malling is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Getting ready for the visit
- Move anything stored near the joints
- Keep children and pets away from the work area

How the job changes by surface
Glass-to-frame joints
Glass-to-frame joints need a sealant that bonds to both. We choose a product that suits both.
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Run a squeegee over the glass when you’re done
- Avoid strong solvents on or near the sealant
- Use a gentle glass cleaner and a soft cloth
- Keep scrapers and blades away from the silicone
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below long before you see it.
Landlord and commercial work in South Malling
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
Why deal with it now?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. In an older home around South Malling, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in South Malling
- Domestic, commercial and hotel work
- You choose the colour before work begins
- Neat joints and a tidy finish
- Any old sealant cut out fully, not covered over

Signs you need glazing silicone in South Malling
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
Any of these means the joints need attention:
- Failed joints on frameless glass
- Silicone pulling away from the glass
- Water getting into a conservatory at the joints
- Sealant that was laid over old silicone and failed
If you look after a building such as South Malling CofE Primary and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- How much experience the applicator has
- What product goes in the joint
- Whether all the old sealant comes out first
- How the joint is cleaned and prepared
