About our glazing silicone in Winchester

Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on shower screens, rooflights and conservatory frames, and people most often call us about leaks where conservatory glass meets the frame and split or lifting silicone on glass.

A place the size of Winchester has every kind of window, from older timber frames to uPVC and aluminium in newer homes. The mastic around all of them ages, and it’s usually the first thing to let the weather in.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Glazing silicone in Winchester: local notes

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For landlords with property near Winchester station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For an older house near a landmark such as St Swithun-upon-Kingsgate Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Winchester: your questions answered

Is glazing silicone in Winchester guaranteed?

Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.

Can you help a landlord with a rental near Winchester station?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.

What sealant do you use?

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 I choose the sealant colour?

Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.

How long before the joint can be used?

It depends on the product and the conditions. We tell you how long to leave it before we go.

Will there be a smell?

Possibly a little. It fades as the sealant cures.

Do you fit new glass or sealed units?

No. A misted unit has failed inside, and a glazier needs to replace it.

What sealant do you use on glazing?

Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.

Surface by surface

Glass-to-glass joints

These joints are on show, so we take care to leave a neat bead.

Conservatory frames

Frame joints face sun and rain all year. A fresh bead seals them again.

What happens on the day

On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work normally takes anything from an hour or two to most of a day, depending on the size of the job. Jobs in a place the size of Winchester range from town-centre flats to offices and family homes. For each, it helps to know about access, parking and where the joints are.

  1. We look at the glazing and agree which joints need resealing.
  2. We cut away the failed silicone.
  3. The surfaces are cleaned with a suitable solvent.
  4. We apply and tool the new silicone.
  5. We inspect the work and test it where we can.

How to prepare

  • Mention any tricky access
  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in

Advice

DIY versus a professional finish

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.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Common problems we fix in Winchester

UV light ages silicone and roof joints get the most sun. 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:

  • Sealant that was laid over old silicone and failed
  • Mouldy sealant around glass panels
  • Failed joints on frameless glass
  • Water running down inside the glass

Schools such as St Bede Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What to look for in a quote

  • How much experience the applicator has
  • Whether VAT is included
  • What insurance they hold
  • When the joint can take water or movement

How we quote for glazing silicone

Every job gets its own quote. This is what makes a difference:

  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • Whether there’s mould to deal with
  • Access and height

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Asking for a quote

When you call or email, these details help:

  • Whether it’s a home or a business
  • Any previous sealing or DIY work
  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

When it isn’t the sealant

Before booking, it’s worth knowing the limits:

  • A roof that has moved or dropped
  • A sealed unit that has misted inside
  • Failed flashing around a conservatory

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Where we work in Winchester

Why it’s worth doing now in Winchester

A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. For landlords in Winchester, failed sealant soon turns into tenant complaints about mould, damp or draughts. It’s simpler to sort between tenants than in the middle of a let.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
