Glazing Silicone in Great Parndon
We cover Great Parndon for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly.
- Black or yellowed silicone on glass joints
- Water running down inside the glass
- Rooflight joints letting water in
How we handle glazing silicone in Great Parndon
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. We work on rooflights, shower screens and glass balustrade bases, and people most often call us about sealant that was laid over old silicone and failed and silicone pulling away from the glass.
Houses in smaller places like Great Parndon 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.
Big or small, you get the same 12-month guarantee.

Why act early in Great Parndon
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In a smaller place like Great Parndon, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

What we’re called out for in Great Parndon
The wrong sealant is a common cause. Some products don’t bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
Signs it’s time to call us include:
- Failed sealant around rooflight glass
- Water running down inside the glass
- Glass-to-glass joints that have split
- Water getting into a conservatory at the joints
In the older streets around Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include

Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Frames and glazing around Great Parndon
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. Harlow, which Great Parndon is part of, is one of England’s post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
If you look after a building such as Jerounds Primary Academy, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Harlow Town station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Common questions in Great Parndon
Will you come out to Great Parndon?

Do you work for landlords with property near Harlow Town station?

Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before any work starts.
Can you fix a leaking conservatory?
That depends where the water is getting in. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.

Yes. We’re fully insured for domestic and commercial work.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most jobs. In a smaller place like Great Parndon, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
How to prepare

- Let us know about earlier repairs to the joints
