When to call us in Stapleford
UV light ages silicone and roof joints get the most sun. Old silicone hardens, cracks and loses its grip to the glass and frame.
It’s worth asking for a quote if you see:
- A quick top-up bead that didn’t last
- Mouldy sealant around glass panels
- Cracked silicone between glass panels
- Shower screens leaking along the wall or tray
Rented homes near Watton-At-Stone station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Glazing silicone in Stapleford, done properly
Glass replacement is not something we do and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that is often where the water gets in. We are often asked to deal with stained, discoloured glazing silicone and sealant that was laid over old silicone and failed, across glass balustrade bases, conservatory frames and rooflights.
In a village or hamlet like Stapleford, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Water coming through the roof rather than a sealant joint
- Condensation trapped between two panes
- Rotten or badly damaged frames
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Frames and glazing around Stapleford
With historic houses such as Aston Bury (about 3.6 miles north-west) nearby, there’s older building stock in the area around Stapleford as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Stapleford Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in Stapleford
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Older cottages and farmhouses around Stapleford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Common questions in Stapleford
Is Stapleford within the area you cover?
Yes, Stapleford is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Watton-At-Stone station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you just put new silicone over the old?
A top-up rarely holds. The new bead can’t grip the old one, so we remove the old sealant and clean the joint.
Can a conservatory leak be sealed?
That depends where the water is getting in. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
Is the work guaranteed?
Our one-year guarantee covers every job.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
How long does the job take?
Typically it takes a few hours for most jobs. Larger jobs naturally take longer.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most jobs. In a small place like Stapleford, access is usually the main thing to plan. 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.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Stick to mild cleaners on glass
- Keep air moving in the conservatory
- Check the silicone on glass every year or so
- Keep conservatory gutters clear of leaves
Check the joints once a year. Catching a split early keeps the repair small.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
