Bald Hills nearly tripled in population between 1961 and 1971, and the housing built during that boom — now 94% of the suburb's roughly 7,000 residents' dwellings — came with shallow aluminium door sills, single drainage slots and seals that were never intended to last sixty years. Add a low-lying river edge, overland flow paths and Brisbane's summer storm pattern, and the result is the call we take most often from this suburb: water tracking under the patio door during heavy rain driven by wind.
Replacing aluminium glass doors in Bald Hills properly means treating drainage as part of the design. We measure the sill height against the outside paving, specify a deeper drained profile, and pressure-seal the frame to the reveal. Every door is glazed to AS 1288:2021, and aluminium glass doors in Bald Hills are made to your measurements at our Brendale factory.
Why Bald Hills Properties Come to Superior Glass
Water at a door sill is almost never the glass's fault, so a supplier who only sells doors will sell you the same problem in a new frame. We diagnose it: whether the outside paving has been built up above the sill over the years, whether the weep holes are blocked, whether the original flashing has failed, or whether the frame is simply under-rated for wind-driven rain on that elevation. Then we quote the fix, which sometimes is not a full replacement.
Wide openings are the second Bald Hills issue. Owners extending a patio door to three or four panels frequently do not realise the wind rating changes with the span, and AS 2047 sets the requirements for external glazed doors accordingly. We calculate it for your site's exposure — a house backing onto open wetland is a different case to one in a sheltered street — and specify frame and glass thickness to match, rather than fitting a standard residential unit and hoping.
-
Drainage designed for the site — sill height checked against external paving, deeper drained profiles specified where water has been getting in.
-
Wind ratings calculated per opening to AS 2047, not assumed, on wide stacking and sliding door spans.
-
Corrosion-resistant hardware for properties near the South Pine River and Tinchi Tamba wetlands where humidity and salt-laden air shorten hardware life.
-
Diagnosis before replacement — if blocked weep holes or failed flashing is the cause, we will tell you and quote the repair.
-

-
Storm damage reglazing with board-up and an itemised report for insurers.
Door and Glazing Services for Bald Hills
Sliding Glass Doors
Replacement patio sliders with a deeper drained sill and pressure-sealed frame — the direct answer to a boom-era door that leaks in a southerly. Suits the suburb's 1960s and 70s brick homes where the opening is sound but the sill detail has failed. See sliding doors.
Stacking Doors
Wide multi-panel openings onto a patio or deck, wind-rated to AS 2047 for the site's actual exposure. Best for homes on the open river and wetland edges where a standard residential rating is not enough for the span. See stacking doors.
Safety Glass Upgrades
Re-glazing existing door and side panels with Grade A toughened or laminated glass to AS 1288:2021. Many original Bald Hills doors still carry unmarked annealed glass, which is a real risk in a house with children or pets. See the doors range.
Security Doors & Screens
Prowler Proof and Crimsafe screens in corrosion-resistant finishes, letting you leave the door open for airflow on humid nights near the wetlands without insects or intruders. Fitted to new or existing doors. See security screens.
Aluminium & Awning Windows
Awning windows shed rain while staying open, which suits a suburb that gets sudden storms. Supplied in the same finish and drainage detail as your new doors. See glass windows.
Emergency Glass Repair
Board-up and same-standard reglazing after storm, branch or impact damage, with documentation suitable for an insurance claim. Twelve minutes from Bald Hills. See glass repair.
Why Bald Hills Doors Fail Differently
Bald Hills sits on the northern edge of Brisbane City where the South Pine River meets the Tinchi Tamba wetlands reserve, and much of its housing dates from the extraordinary decade between 1961 and 1971 when the suburb's population nearly tripled. At the 2021 Census, 94% of dwellings were separate houses. The low-lying northern and eastern parts of the suburb carry flood and overland flow considerations, and even well away from the river, storm runoff across flat backyards finds its way to the lowest doorway.
Boom-era aluminium doors were built with a shallow sill and one or two small weep slots. Six decades of garden mulch, repainting and sill silt block those slots, and in the same period many owners have paved, decked or concreted outside the door, sometimes raising the external level to within millimetres of the sill. When wind-driven rain hits that elevation, water sits in the track with nowhere to go and comes inside. Owners read it as a leaking door; it is usually a drainage path that no longer works.
For homeowners this matters because the damage is not to the door — it is to flooring, skirting and carpet, repeatedly. So our approach here starts outside. We check the external level against the sill, look for blocked or painted-over weep holes and failed flashing, and if those are the cause we quote a repair rather than a replacement. Where the frame really is past it, we install aluminium glass doors in Bald Hills with a deeper drained sill profile, a pressure-sealed perimeter and, on exposed elevations, a raised threshold detail. Hardware is specified for the humidity near the wetlands, and glass thickness follows the wind rating calculated for the opening's span and exposure. Getting aluminium glass doors in Bald Hills right is a water-management job first and a glazing job second.
