Nash Lee homes and the weather
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.
Homes close to Church of St Peter and St Paul include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to Stoke Mandeville station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you look after a building such as John Colet School, its window and door frames need their mastic kept sound, just like a home’s.

Glazing silicone in Nash Lee
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you have rooflight joints letting water in and drips on the inside of a conservatory window, we can help, on conservatory frames, glass balustrade bases and rooflights alike.
Mastic can only go onto a dry, clean joint, so window work in Nash Lee is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes as standard.

FAQs for Nash Lee
Can you help a landlord with a rental near Stoke Mandeville station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Can you do glazing silicone in Nash Lee?
Yes. We work across London and the South East, and Nash Lee is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Where are you based?
Mr Mastic is based in Crawley. We cover Nash Lee and the rest of Buckinghamshire, along with the rest of our area.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can you just put new silicone over the old?
It doesn’t last. The new bead can’t grip the old one, so we remove the old sealant and clean the joint.
Do you reseal glass shower screens?
We can. We remove the old silicone carefully before cleaning and resealing.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Leave it or put it right?
A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Around Nash Lee, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Landlord and commercial work in Nash Lee
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Honest limits
We will not take on work that won’t last, so here’s what sealant cannot put right:
- A sealed unit that has misted inside
- A broken pane or roof panel
- Rotten or badly damaged frames
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Where we work in Nash Lee
- Rooflights
- Conservatory frames
- Glass-to-frame joints
- Shower screens
- Glass balustrade bases
- Glass-to-glass joints
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Open vents or windows to let moisture out
- Don’t use a blade near the sealant
- Get a new leak looked at quickly
- Look over the glazing joints once a year
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from an hour or two to most of a day, depending on the size of the job from start to finish. Somewhere as small as Nash Lee, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules

Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
