King Double Glazing — Brooklyn Glass Pty Ltd

Hi, I'm Tas. Glass has been part of my life for as long as I can remember — and after more than four decades in the industry, I still love what I do. King Double Glazing is the result of everything I've learned: a smarter, more honest way to upgrade homes and buildings.

Tas Markou, founder of King Double Glazing, Melbourne glazing specialist

The Origin Story

My father was a glazier. I did my first glass replacement at seven years old.

What started as helping out in the family workshop quickly became a lifelong calling. After finishing school, Tas stepped into the industry professionally — working alongside large glazing companies before moving into window manufacturing.

Over the years, he gained hands-on experience across both domestic and commercial projects, eventually running two specialist companies in each area. That journey gave him a granular understanding of how the industry works — and where it consistently lets customers down.

"I've seen homeowners pay double what they should. That's what pushed me to do something different."

Why King?

A SmarterWay to Glaze

With more than 40 years in the trade, Tas has seen where the industry falls short. King Double Glazing was built to fix that — a retrofit double glazing system designed to work with most existing domestic and commercial frames, delivering high-quality results while cutting costs by at least 30%.

01

Works With Most Frames

Timber or aluminium — existing frames stay put. No demolition, no mess.

02

At Least 30% Cheaper

Compared to full window replacement, with equivalent thermal and acoustic performance.

03

Transparent Pricing

No vague quotes, no site visits just to give a number. Itemised estimates online.

Honest Advice

No Pressure.Just Experience.

Tas is family-oriented and genuinely enjoys sharing what he's learned over four decades in the trade. There's no hard sell, no pushy follow-ups, and no obligation to commit on the spot.

"Whether you're ready to move forward with a project or just want some honest advice, I'm always happy to have a chat and point you in the right direction."

That philosophy is baked into everything King Double Glazing does — from the way quotes are presented to the way jobs are handled on-site. You deal with Tas directly. No middlemen. No runaround.

Heating bill dropped noticeably in the first month. Our Victorian terrace was a nightmare to heat — now the lounge actually holds temperature overnight. The retrofit took one day and the crew left the place spotless.

We live 40 metres from a tram stop. The acoustic difference after the laminated glass went in was honestly shocking. I didn't expect it to be that dramatic. Wish we'd done it ten years ago.

Got three quotes. King came in $2,100 less than the next cheapest and finished the job in a single day. No upselling, no vague pricing — the final invoice matched the online estimate exactly.

Was sceptical about retrofit vs full replacement. A friend told me to just do the full windows. Glad I ignored him. You cannot tell the difference visually, and the performance specs are identical.

West-facing bedroom was genuinely unusable in summer — 34°C at 9pm. Tinted Low-E glass has fixed it completely. Air con barely runs now. The estimate tool online gave me the exact price before anyone even came out.

Used the instant estimate tool to budget before committing. No sales call, no pressure. The price they quoted was the price I paid. That kind of transparency is rare in the trades.

Our bedroom faces Sydney Road. Friday and Saturday nights were unusable — we were wearing earplugs to sleep. The acoustic laminated glass has completely changed the situation. The tram noise that used to wake us at 6 am is now barely audible. I genuinely did not think glass could make that much difference.

Flight path noise was the main reason we almost moved. A friend suggested acoustic glazing as a last resort before we listed the house. We're not moving. The difference in the front rooms is night and day — my daughter actually sleeps through now. Worth every cent.

Our gas bills were brutal every winter — the old single-pane windows were just radiating cold into the rooms. We went with Low-E double glazing throughout. First winter after: $380 less on gas over the quarter. The house holds heat in a way it never did before. We wished we'd done it when we bought the place.

I was skeptical about the energy saving claims — they always sound too good. But the condensation alone proved the point: zero condensation on the inner pane since installation, where before it was streaming every winter morning. The heating runs half as often. The numbers are real.

We were told by two other glaziers that we'd need council approval and a heritage consultant before touching the windows. King told us that a glass-only retrofit is permit-exempt — kept the frames, just replaced the glass. They were right. No permit, no consultant, done in one day. The house looks exactly the same from the street, and the draughts are completely gone.

Oliver & Kate B.

Our Victorian terrace is on the Heritage Overlay and I was nervous about any window work. King assessed the frames, confirmed the retrofit was permit-free, and did the whole house in a day. The original sash windows still look original — you'd never know the glass had changed. Warmer, quieter, no heritage headache.

Woke up to a burglary at 3am — back door glass completely smashed. Called King at 6am, glazier was here by 7:45am, property secured before we left for work. Didn't expect anyone to show up that fast. They boarded it properly, not just cardboard, and came back two days later with the permanent glass. Exactly what you need when you're in shock.

Tenant called me at 7pm on a Friday — kitchen window smashed. King had a glazier there by 9pm and replaced the glass permanently on the same visit. No board-up, no return trip, no landlord nightmare over the weekend. I've used them for three emergency jobs now and the response is always the same.

Storm took out my lounge window at 11pm on a Wednesday. I expected to be told someone would come in the morning. King had a glazier here within the hour. He cleaned up the glass, boarded the frame properly, and the permanent replacement was fitted two days later. Professional job, not a handyman with a piece of wood.

We manage 14 strata buildings across Melbourne. King handles all our glazing — routine replacements, double glazing retrofits on older blocks, and emergency call-outs. The invoicing is clean, the pricing is consistent, and they show up when they say they will. That last part is rarer than it should be.

Needed a full shopfront glass installation done over a weekend so we could open Monday. King confirmed the timeline, showed up Saturday morning, and were done by Sunday afternoon. The glass is immaculate — not a mark on it. Every trade we brought in for the fitout delivered late except these guys.

Used King on a 12-unit apartment project — double glazing throughout plus frameless balustrades on the upper levels. Scope was substantial and they handled it without the project management headaches I've had with other glaziers. Itemised quotes, predictable scheduling, zero defects at handover. We're using them on the next project.
