- Sealant that was laid over old silicone and failed
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Open vents or windows to let moisture out
- Keep harsh solvents off the silicone
- Run a squeegee over the glass when you’re done
- Stick to mild cleaners on glass
Follow the cure time we give you before the joints get wet so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.
Glazing silicone in Netteswell, done properly
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We work on conservatory frames, glass balustrade bases and glass-to-frame joints, and people most often call us about shower screens leaking along the wall or tray and stained, discoloured glazing silicone.
Houses in smaller places like Netteswell can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

What else we do in Netteswell
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on how many joints need doing and we leave things clean and tidy. A visit to Netteswell is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.

- The joints are checked before we leave.
Getting ready for the visit

Netteswell: your questions answered
Do you cover smaller places like Netteswell?

Can you reseal a frameless shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.

No. We work neatly, protect the area around the joints and tidy up afterwards.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracked or broken glass
- A frame that needs repairing or replacing
- A roof that has moved or dropped
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Landlord and commercial work in Netteswell
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Common problems we fix in Netteswell
The wrong sealant is a common cause. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
Signs it’s time to call us include:
- Water getting into a conservatory at the joints
- Failed sealant around rooflight glass
- Split or lifting silicone on glass
- Water running down inside the glass
Homes close to St Andrew's Methodist Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Netteswell homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Netteswell is part of Harlow, one of the post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
Schools such as Freshwaters Primary Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Harlow Town station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

What happens if it’s left?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In an older home around Netteswell, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
