Windows and doors in Prestwood
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hughenden Manor (about 3.4 miles south) nearby, there’s older building stock in the area around Prestwood as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Holy Trinity Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Prestwood Junior School, the mastic around its windows and doors needs looking after like any other building’s.

How we handle glazing silicone in Prestwood
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. If you are dealing with water getting into a conservatory at the joints and glass-to-glass joints that have split, we can help, whatever the surface.
Houses in smaller places like Prestwood can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
Big or small, you get the same 12-month guarantee.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes anything from an hour or two to most of a day, depending on the size of the job. In a smaller place like Prestwood, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Advice
Leave it or put it right?
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames usually just need resealing. Homes in smaller places like Prestwood can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.
What you get with us
- Colour picked to suit the job
- Neat joints and a tidy finish
- A choice of colours where the product allows
- We agree the colour with you first

Prestwood: your questions answered
Is Prestwood in your area for glazing silicone?
Yes. Our work covers London and the South East, and Prestwood is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Great Missenden station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Can a conservatory leak be sealed?
If the water is coming in through failed sealant joints, yes. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Do you seal glass balustrade bases?
We can. We cut out the failed sealant and reseal the base joint using a sealant that suits the materials.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you offer different sealant colours?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Surface by surface
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it before new glazing silicone goes in.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Open vents or windows to let moisture out
- Clean glass with a mild cleaner and a soft cloth
- Get a new leak looked at quickly
- Keep scrapers and blades away from the silicone
Do not use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
Common problems we fix in Prestwood
Using a sealant not made for glass causes many failures. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
Most people get in touch when they notice one of these:
- Split or lifting silicone on glass
- Water getting into a conservatory at the joints
- Mouldy sealant around glass panels
- Leaking glazing joints on a rooflight
Rented homes near Great Missenden station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
What your quote should include
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- What insurance they hold
- How long the guarantee is
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracked or broken glass
- A sagging or failing conservatory roof
- Water coming through the roof rather than a sealant joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
