About our glazing silicone in Frithsden
We renew glazing silicone on conservatories, 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. If you have water running down inside the glass and mouldy sealant around glass panels, we can put it right, on shower screens, conservatory frames and glass-to-glass joints alike.
Around Frithsden, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, large or small.

Frithsden questions
Will you come out to Frithsden?
Yes. Frithsden is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do glazing silicone in Frithsden?
Yes. We work across London and the South East, and Frithsden is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Will resealing stop my conservatory leaking?
Often, if the leak is at a sealant joint. We trace the leak first, so you know what you are paying for.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Do you fit new glass or sealed units?
No. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.

Why it’s worth doing now in Frithsden
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. Around Frithsden, 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 the amount of work, 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, so you know where you stand.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Aftercare tips
After the cure time, these simple habits help:
- Open vents or windows to let moisture out
- Use a gentle glass cleaner and a soft cloth
- Look over the glazing joints once a year
- Act on drips or damp patches early
Squeegee a shower screen after each shower and let the room air. It helps stop mould getting into the silicone.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to most of a day, depending on the size of the job and we leave things clean and tidy. Somewhere as small as Frithsden, 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.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Frames and glazing around Frithsden
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Potten End CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Lawrence include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Berkhamsted station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
