Window replacement in Berwick.
Berwick splits cleanly into three window jobs: original-Berwick heritage cottages along High Street with rotting timber sash; the big 1990s–2000s brick-veneer estates (Berwick Springs, Berwick Waters, around Akoonah Park) with chalky single-glaze aluminium; and the new-build estates north of the freeway (Edenrise, Eden Park) where owners are upgrading the standard-spec builder windows to double-glaze or punching out the back wall for bigger sliding doors.
The Berwick window story.
The chalky-aluminium era (built 1992–2010).
Roughly 60% of our Berwick jobs are the same house: 4-bed brick-veneer on a 600–750m² block, builder-spec mid-range aluminium frames from the era, single-glazed, white powder coat now gone chalky, rubber gaskets hardened, sliding-window rollers either jammed or screeching. Condensation streaks on the inside of every window in July and August. We re-window the whole house in two–four days for $14K–$22K including a double-glaze upgrade, and the difference in the next winter is instantly obvious — warmer rooms, no condensation, no mould reforming on the architraves.
Edenrise & Eden Park new builds (2018–2024).
Newer estate homes around Edenrise typically come with thicker aluminium frames and energy-rated glass already — the windows are fine. What owners ask us about here is upgrading the standard 2.4m living-room sliding door to a 3.6m or 4.2m stacker for a proper indoor-outdoor connection, or punching a bifold across the family room. Standard new-build sliding door: $2,500–$3,500. Stacker upgrade: $4,500–$6,500. Bifold: $6,000–$9,000.
Heritage cottages around High Street & old Berwick.
The original Berwick township homes — weatherboard or double-brick cottages with timber sash windows — need a like-for-like timber replacement, not aluminium. Council planning prefers it, and an aluminium frame on a Victorian cottage looks wrong from the street. Stegbar Timber and Trend Timber both make new sash windows that match the old profiles. Cost is higher ($1,200–$2,400/window) but the house stays original-looking and you get modern weather seals.
