About us

Glaziers in Iver, working across London.

New Ocean Glazing Ltd supplies, fits and repairs windows and doors, and makes the double-glazed units that go in them.

Small repairs to whole new builds.

We work on everything from a straightforward broken pane to the full design and installation of new windows and doors. Our installers are used to the awkward parts of a job: bay windows, wide openings and structural glazing.

We manufacture and install double glazing in aluminium and in uPVC made with REHAU profiles from Germany. We fit windows, flush windows, front and back doors, bi-folds, composite doors, conservatories, porches and roof lanterns, and we make double-glazed sealed units, so a misted or broken pane can be replaced to size.

New jobs go up on our Instagram first, and you'll find 348 photos in our work.

Whatever the job, we'll give you a clear price that works within your budget, and a long-term fix rather than a patch.

Highlights from our Google reviews.

  • I had my windows and porch doors replaced by this company and the experience was excellent from start to finish. I live in a conservation area, so the design and detailing had to be exact to meet council requirements. They understood this straight away and replicated everything perfectly. … The quality of the work is outstanding, and the pricing was competitive compared to others I looked at locally.

  • Just had 3 windows and a door installed by Mr Diljit, Mr Pankaj and Mr Manjeet and what a professional job they have done. Very happy with the quality and finish of the work. Not only windows are amazing but the workmanship is top notch as well and at a great price. Will highly recommend them.

  • I am extremely happy with the work carried out at my property. We had Whole house window fitted a few weeks ago (15 windows in total). … As we live within the property they respected our space and were very mindful of not getting in the way making sure they kept all areas clean or cleared up after themselves. … We have had windows fitted before from this company and chose to use them again.
