Glazing silicone in Lee
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. If you have new silicone smeared over old sealant and leaking glazing joints on a rooflight, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in Lee is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months.

How the job changes by surface
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Shower screens
Mouldy or lifting sealant on a screen leaks. Cutting it out and resealing fixes it.
Glazing silicone in Lee: local notes
Lee is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Romsey station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. Schools such as Oasis Academy Lord's Hill are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Lee is about 2 miles south of Romsey, in Hampshire. Anywhere in SO51, we cover glazing silicone for homes and businesses. Lee is one of 683 towns and villages in Hampshire where we work.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
Lee questions
Is Lee within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Romsey station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
How long does glazing silicone take?
That depends on how much there is to do, but most jobs take a few hours, depending on how many joints need doing. We will give you a better idea when we quote.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Are you insured?
Yes. Mr Mastic is fully insured.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Leave it or put it right?
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes, and we will tell you if that’s not the case. Around Lee, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

What else we do in Lee
When to call us in Lee
Heat and cold make glass and frames move at different rates. Over years, that movement tears the silicone.
The most common problems we see are:
- Failed joints on frameless glass
- Rooflight joints letting water in
- Water getting into a conservatory at the joints
- Leaks from the base of a shower screen
Homes close to Church of St Boniface include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

How the visit works
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 a few hours, depending on how many joints need doing. For a village or hamlet like Lee, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Tell us if parking is tricky
- Move anything stored near the joints
- Mention any tricky access
