Questions from Church End
Is parking an issue for glazing silicone in Church End?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near Harlesden station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Photos help us see what’s there.
How we handle glazing silicone in Church End
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for leaks from the base of a shower screen and drips on the inside of a conservatory window, across shower screens, glass-to-frame joints and conservatory frames.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Frames and glazing around Church End
Historic houses like Fenton House (about 3.2 miles east) are a reminder that the area around Church End has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Managing a site like St Mary's CofE Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Harlesden station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

When to call us in Church End
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the edges begin to peel.
Keep an eye out for any of the following:
- Split or lifting silicone on glass
- Black or yellowed silicone on glass joints
- New silicone smeared over old sealant
- Failed sealant around rooflight glass
Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Church End, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We look over every joint and, where we can, test it with water.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky

What the job involves on each surface
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Landlord and commercial work in Church End
For anyone letting property in or around Church End, several properties can be quoted together. Just tell us the addresses and what each one needs.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
If the problem is a misted unit or a broken panel, sealant won’t help. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Church End, the repair is bigger than a sealant job.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before we start.
Why Church End customers choose us
- A choice of colours where the product allows
- Old sealant always removed completely
- A 12-month guarantee on all work
- ARBOMaster approved applicator
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A frame that needs repairing or replacing
- A broken pane or roof panel
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
