Window replacement in Berwick, step by step, day by day.
Accepted quote to finished job is 5 to 8 weeks, and nearly all of that is factory time. The crew is on site 1 to 3 days for a typical 10 to 12 opening Casey house. Each standard opening is out and sealed in 1 to 3 hours, a sliding door takes 3 to 5, and your house is never open to the weather in more than one place at a time.
Every stage, how long it takes, and what you have to do.
Timings below are for a single-storey Berwick, Narre Warren or Cranbourne house with 10 to 12 openings and one sliding door, all in their existing structural openings.
| Stage | How long | What happens | What you need to do |
|---|---|---|---|
| 1. Free measure and quote | 45-90 min on site, quote in 7 days | Every opening measured twice, elevations and wind exposure noted, glazing options priced both ways | Be home, unlock side gates, say which rooms bother you |
| 2. Order and deposit | Same week | Colour, glazing, hardware and screen type locked in and the order released to the factory | Choose the powder coat colour, sign the scope, pay the deposit |
| 3. Check measure | 30-45 min, 1-2 weeks later | Second measure against the shop drawings before anything is cut. This is where errors get caught | 15 minutes of access, confirm handle sides and opening directions |
| 4. Manufacture | 4-6 weeks aluminium, 8-12 timber or uPVC | Frames extruded, powder coated, glazed and assembled. Nothing happens at your house | Book leave or a work-from-home day for the install week |
| 5. Delivery and set-up | 7am to 8am, day 1 | Units unloaded and stood against the wall, floors covered, dust screens hung, power leads run | Clear the driveway, keep pets inside, gates unlocked |
| 6. Strip-out and fit, per opening | 1-3 hours each | Sash and glass out, frame cut free, opening cleaned, new frame packed, plumbed, levelled, fixed and flashed | Stay out of that room, keep kids and pets away from glass |
| 7. Sliding or stacker door | 3-5 hours | Heavier frame, sill set in a bed of sealant, tracks levelled, panels hung and adjusted, threshold waterproofed | Clear the alfresco and the internal traffic path for the day |
| 8. Make-good and sealing | Last afternoon | Reveals patched, architraves refitted, backing rod and neutral-cure silicone tooled inside and out | Nothing. Do not touch a fresh bead for 24 hours |
| 9. Clean-up and handover | 30-60 min | Vacuum, glass cleaned, screens fitted, every sash and lock demonstrated, warranty and compliance paperwork handed over | Walk every opening with the installer before you sign off |
| 10. Painting | 3-7 days after | Patched reveals and architraves are painted once the filler and sealant have cured | Your painter, or ours. Do not paint over fresh silicone |
Two-storey work adds a scaffold day at each end. Wet weather stops new openings being cut, not the fit-off. Call (03) 9022 6418 if you need a date locked around school holidays.

Want the install day mapped out for your house?
We give you the room order and the finish time before we start, so you can plan the week around it.
Access, noise, dust and the things nobody warns you about.
Access and parking. We need the driveway from 7am for a ute and a trailer, and a clear path from there to each elevation. New estate streets through Clyde North, Berwick Waters and parts of Cranbourne East are narrow with kerbside parking on both sides, so tell us at the measure if the truck will not fit past a parked car. On the older Doveton and Endeavour Hills blocks the usual obstacle is a side gate too narrow for a 2.4 metre sliding panel, which we would rather find out at the measure than on install morning.
Power and water. A standard 10 amp external power point runs everything we use. If there is no external outlet we run a lead from inside, which means a door propped for the day. An outside tap is used for wet-cutting and clean-up. Neither is a deal breaker, but both are worth mentioning up front.
Noise. The genuinely loud parts are short. Cutting an old frame free with a multi-tool or grinder takes 10 to 20 minutes per opening and drilling the fixings adds a few minutes. Victorian residential noise rules set the hours for power tools on domestic premises: not before 7am or after 8pm Monday to Friday, and not before 9am or after 8pm on weekends and public holidays. We work inside those hours, and we do not do out-of-hours installs.
Dust and smell. Brick, render and mortar dust contains crystalline silica, so cutting is done with on-tool extraction or wet-cut wherever possible, and dust screens go up across doorways. Even done properly, expect a fine film within two metres of each opening and a bit of grit on the floor until the final vacuum. Neutral-cure silicone has a mild odour for a few hours and is essentially gone by the next morning. If anyone in the house has a respiratory condition, tell us and we will schedule their room for a day they can be out.
Pets, kids and working from home. An opening sits empty for an hour or two, gates get propped and there is glass on the ground. Dogs go to a run or to day care, cats go in a closed room with a sign on the door. Working from home is completely normal: ask for the room order and book calls for before the first cut or after about 3pm when the day moves to sealing and clean-up.
Weather. We fit opening by opening rather than stripping the house out, so the house is never widely exposed. In steady rain we stop cutting new openings and finish what is already out, which is how a two-day job becomes a three-day job in a wet week. Sustained wind over about 40km/h stops us handling large glass on a ladder or a scaffold, for obvious reasons. We will call you the afternoon before if the forecast is going to move the date.
What a clean site looks like, and where the waste goes.
A finished job means every sash operates with one hand, every lock engages, screens are fitted, the internal and external sealant beads are tooled evenly with no smears on the brickwork, the reveals are patched flat and ready for paint, the glass is clean both sides, the floors are vacuumed and there is nothing left in the garden beds. Offcuts, packaging film, old screens and the old frames all leave with us the same day. Walk every opening with the installer before the final payment and operate everything yourself: it is much easier to adjust a stiff sash while the crew is still standing there.
The old aluminium frames go to a scrap metal recycler after the glass is stripped out, which is exactly why removal and disposal is included in our price rather than added as a line item. Toughened and laminated glass cannot go in a kerbside recycling bin and goes to a transfer station as hard waste. Old timber sashes from pre-1970 houses may carry lead-based paint, so they are bagged and handled separately rather than cut or sanded on site. If you would rather keep a couple of old sashes for a shed or a greenhouse, say so at the measure and we will leave them.
The honest bit. Two things we will not do. We will not open a wall in sustained rain to keep a schedule, even if it costs us the day, because a wet frame cavity is a mould problem you will be living with later. And we will not install into a tenanted property without the tenant's written agreement to the dates, because a job worked around an unhappy household ends badly for everyone. If you are chasing us because a window is broken right now rather than worn out, the faster route is often an insurance claim and a temporary board-up, which we cover on the window insurance claims page. If you are weighing up doing part of it yourself, the honest split of what is a weekend and what is not is on the DIY versus professional page, and once the job is done the aftercare routine is on the maintenance page.
Book the measure and we will map out your install week.
