If you own a weatherboard cottage in Williamstown, you already know the maintenance routine. Sand, prime, paint, repeat. Salt air from Hobsons Bay and Port Phillip strips paint off timber frames faster than anywhere inland, and the single glazing behind those frames does nothing for noise or insulation. Nu-Eco installs Williamstown UPVC windows and doors that don’t corrode, don’t rot, and never need a coat of paint. We supply and install double glazing in Williamstown using profiles designed to slot directly into existing timber openings without structural work.

What Coastal Exposure Actually Does to Williamstown’s Windows
Williamstown is exposed to the bay on three sides, which is part of what makes it a great place to live and a terrible place to maintain timber windows. The heritage streetscapes along Nelson Place, Ferguson Street, and around the Williamstown Beach precinct are protected under Hobsons Bay Council’s planning scheme. Original cottages from the 1870s through to Edwardian homes from the early 1900s still have their timber sash windows, and most are showing their age. Putty cracks. Timber swells after rain and shrinks in summer. Paint lifts within a few years of going on.
Nu-Eco’s 70mm UPVC profiles are a permanent fix. The material is inert to salt, UV, and moisture. Steel reinforcement sits fully enclosed inside the frame, sealed from the elements. For Williamstown’s heritage homes, our fully sculptured windows match the moulding detail of original Victorian joinery, and our double hung windows reproduce the sash mechanism. Paired with 28mm Argon gas filled IGUs, Low-E coated as standard, you get a certified U-value of 1.5 W/m²K and up to 80% noise reduction.

Replacing Windows in Williamstown’s Heritage Precincts
Hobsons Bay Council protects a large number of Williamstown’s residential streets under heritage overlays, from the Nelson Place precinct through to the Williamstown Beach area. If your home falls within one of these precincts, replacing external windows requires a planning permit. That’s where the profile matters.
Our 70mm UPVC profile slots into existing timber openings without changing the frame size. Fully sculptured profiles reproduce the moulding lines of Victorian and Edwardian timber windows, and a Cream or White exterior finish keeps the look consistent with surrounding cottages. We supply profile samples and technical documentation for your permit application, and we’ve been through this process with Hobsons Bay before.
Timber, Aluminium, and Why Both Struggle in Williamstown
Timber windows in a coastal suburb like Williamstown need repainting every three to five years. Once the paint starts lifting, moisture gets in and rot follows. Aluminium replacement frames avoid the rot problem but introduce a new one: the hardware corrodes. Locks seize, hinges stiffen, and seals degrade. UPVC has neither issue. It’s inert to salt, UV, and moisture.
Our profiles have been UV tested by Allunga Exposure Laboratory in Townsville, absorbing 35,789 MJ/m² of solar radiation, over double the 15,000 MJ/m² required for Australian compliance. The lead-free compound uses calcium organic stabilisers. No painting, no staining, no treating. Soapy water and a cloth is the full maintenance routine. See our certifications page for the testing data.
Frequently Asked Questions
Understanding the technology behind premium double glazed windows and doors.
A standard 900mm x 1200mm casement awning window costs approximately $1,600 to $1,800 installed. The final price depends on window size, quantity, glass specification, and any extras like colour finishes, reveals, or flyscreens. We provide a free on-site measure and quote with no obligation.
Probably. Williamstown has extensive heritage overlay coverage under the Hobsons Bay Planning Scheme, and most residential streets in the older parts of the suburb fall within a precinct. External window changes in these areas need a planning permit. We can supply profile samples and technical documentation to support your application.
Yes. Our fully sculptured profiles reproduce traditional Victorian moulding detail, and our double hung windows replicate the sash mechanism. A Cream or White finish matches the cottage aesthetic, and dual-colour options let you have a different finish inside. See the range on our windows page.
We install French doors, front doors, sliding patio doors, bi-fold doors, and composite doors. All use the same sealed IGU specification as our windows, so thermal and acoustic performance carries through every opening. Finance is available through Green Loans and Handypay.
