FAQs for Hither Green
Can parking be tricky for a visit in Hither Green?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you cover Hither Green for glazing silicone?
Yes. Our work covers London and the South East, and Hither Green is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
What sealant do you use on glazing?
We pick a glazing silicone to suit the materials. Neutral-cure silicone is the usual choice.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
How long will you be here?
A typical job takes anything from an hour or two to most of a day, depending on the size of the job. We will confirm how long when we quote.
Glazing silicone for homes and businesses in Hither Green
Sealant on glazing doesn’t last for ever. Weather and movement take their toll, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. Typical jobs include shower screens leaking along the wall or tray and new silicone smeared over old sealant, on glass-to-frame joints, glass balustrade bases 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.
Whatever the size of the job, it’s backed by our 12-month guarantee in Hither Green and across Greater London.

Windows and doors in Hither Green
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. 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 site and facilities teams at buildings such as Brindishe Manor School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Hither Green station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. As a London address, Hither Green can be tricky for parking: let us know about parking bays, permits or a driveway.

The process
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most jobs. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

What affects the cost of glazing silicone
For a quick quote, just ask. The main things that affect it are:
- Whether the work is at height
- Any working-time requirements on site
- The size of the job
- The old material and how stubborn it is
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- The problem you’ve noticed
- If someone has resealed it before
- Where the job is, and your postcode
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Why act early in Hither Green
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. In a flat in Hither Green, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before work begins.

Surface by surface
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. When it fails, water can sit in the channel.
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
When it is not the sealant
A few problems are outside what sealant work can do:
- A sealed unit that has misted inside
- A roof that has moved or dropped
- Failed flashing around a conservatory
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
Joints and surfaces we work on
- Shower screens
- Glass balustrade bases
- Glass-to-frame joints
- Conservatory frames
- Rooflights
- Glass-to-glass joints
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
