Trusted glazing silicone in Cowley

How it works

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many joints need doing. In a smaller place like Cowley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. First, we check where the water gets in.
  2. The failed silicone is cut out without marking the glass or frame.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. We check the finished joints and test with water where it’s safe.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • On commercial sites, let us know about site rules
  • Tell us if parking is tricky

How we handle glazing silicone in Cowley

We do not replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. If you have black or yellowed silicone on glass joints and glazing silicone that has cracked or come away, we can help, on rooflights, conservatory frames and glass-to-frame joints alike.

Homes around Cowley range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.

Big or small, it’s backed by our 12-month guarantee in Cowley and across Oxfordshire.

Frames and glazing around Cowley

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. With historic houses such as Holywell Manor (about 2.1 miles north-west) nearby, there’s older building stock in the area around Cowley as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Schools such as Our Lady's Roman Catholic Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Oxford station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Work for landlords, hotels and businesses

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

How to look after the new joints

So the new joints stay in good condition:

  • Act on drips or damp patches early
  • Keep air moving in the conservatory
  • Avoid strong solvents on or near the sealant
  • Stick to mild cleaners on glass

Follow the cure time we give you before the joints get wet. After that, clean glass with a mild cleaner.

If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.

What affects the cost of glazing silicone

Call for a quick quote. What matters most is:

  • The product the joint needs
  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • Whether it has been sealed before
  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking

We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.

That depends on where the joints are. For work indoors, someone needs to let us in.

Common problems we fix in Cowley

The wrong sealant is a common cause. Some products do not bond well to glass, and acetoxy types can attack some frame materials.

These are the problems we are asked about most:

  • Failed joints on frameless glass
  • Stained, discoloured glazing silicone
  • Leaks from the base of a shower screen
  • Failed sealant around rooflight glass

Homes close to Church of St Luke include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Before booking anyone

  • What product goes in the joint
  • What preparation is included
  • The length of the guarantee
  • Whether they’re fully insured

How to choose a mastic man

Why act early in Cowley

Replacing a conservatory roof is major work. If the leak is a failed sealant joint renewing the joint is the simpler fix. If the roof is the problem, we will say so. In an older home around Cowley, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Why us?

  • Anti-fungal sanitary silicone in wet areas
  • Experience in homes, commercial sites and hotels
  • We agree the colour with you first
  • A choice of colours where the product allows
