Glazing silicone in Dunsden Green, done properly

A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points, and we reseal both. If you have failed sealant around rooflight glass and leaks where conservatory glass meets the frame, we can help, whatever the surface.

Around Dunsden Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

There’s a 12-month guarantee on every job, large or small.

Why act early in Dunsden Green

A new conservatory roof is a big job. Where the water is getting in through sealant renewing the joint is the simpler fix. If the roof is the problem, we will say so. Around Dunsden Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Why book with us

Old sealant always removed completely
Every job guaranteed for a year
Colour agreed with you before work begins
White, clear, grey or another colour, product permitting

For landlords 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.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Signs you need glazing silicone in Dunsden Green

UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.

If you can see any of these, it’s time to have the joints looked at:

Water running down inside the glass
Water escaping where a screen meets the wall
Cracked silicone between glass panels
Glazing silicone that has cracked or come away

For site and facilities teams at buildings such as St Martin's Catholic Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Questions to ask before you book

What product goes in the joint
When the joint can take water or movement
How much experience the applicator has
Whether they seal over old material or remove it

How to choose a mastic man

Surface by surface

Rooflights

Water around a rooflight is not always the sealant. We find the cause first.

Glass-to-glass joints

You see these joints clearly, so we take care to leave a neat bead.

What glazing silicone looks like in Dunsden Green

Historic houses like Greys Court (about 3.9 miles north) are a reminder that the area around Dunsden Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Letting a property close to Reading station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Homes close to All Saints Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

The process

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours, depending on how many joints need doing, depending on how much there is to do. In a small place like Dunsden Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

We trace the leak and confirm it’s a sealant joint.
The failed silicone is cut out without marking the glass or frame.
We clean the glass and frame so the new silicone bonds.
We lay the new bead and tool it smooth.
We check the finished joints and test with water where it’s safe.

How to prepare

Mention any leaks or damp you’ve noticed
Where the joints are inside, avoid wetting them before we arrive
Tell us about access, such as stairs, a lift or high-level joints
