Windows and doors in Farnborough
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 Tower Hill Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Christopher, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our glazing silicone in Farnborough
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. If you have mouldy sealant around glass panels and drips on the inside of a conservatory window, we can put it right, on shower screens, glass-to-frame joints and glass balustrade bases alike.
Walls in Farnborough that face the prevailing wind take the most weather, and that is usually where the sealant gives up first. Checking every frame, not just the obvious one, is time well spent.
Every job comes with our 12-month guarantee, wherever you are in Hampshire.

Signs you need glazing silicone in Farnborough
Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.
Look out for these signs:
- Water tracking down the inner face of the glass
- Failed sealant around rooflight glass
- Failed joints on frameless glass
- Shower screens leaking along the wall or tray
Rented homes near Farnborough Main station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

How the visit works

Most jobs take a few hours, depending on how many joints need doing. Parking in a town like Farnborough is usually straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.

Advice
Landlord and commercial work in Farnborough
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
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.
Why deal with it now?
Replacing a conservatory roof is major work. Where the water is getting in through sealant, resealing is far simpler. If the roof is the problem, we’ll say so. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.

What affects the cost of glazing silicone
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- The number and length of the joints
- Whether the work is at height
- Any mould that needs treating
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Where the job is, and your postcode
- How we’d reach the joints
- How many joints, rooms or windows are involved
- If someone has resealed it before
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Looking after it afterwards
So the new joints stay in good condition:
- Squeegee the shower screen after each use
- Ventilate the conservatory to cut condensation
- Use gentle products around the joints
- Keep scrapers and blades away from the silicone
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else, and we’ll tell you which.
