Structural Alterations, Windows & Doors
Structural wall alterations, window enlargements, and custom door installations in Byron Bay.
Service Overview
Langford Build performs structural alterations that improve natural light and ventilation. We coordinate structural wall removals, enlarge window openings to improve natural light and ventilation, replace old sliding doors with premium timber bifold doors, and update internal layouts safely.
Who this is for:
- Homeowners wanting to replace old windows with larger, energy-efficient glazing packages
- Clients looking to remove walls to connect their kitchen and dining space
- Property owners wanting to install premium timber bifold or stacking doors to verandas
- Those seeking licensed carpenters for structural modifications and framing
Suitable project scopes:
- Structural wall removals and beam installations
- Window enlargements and timber/aluminium window replacement
- Custom timber bifold and cavity slider door installations
- Reworking internal framing and door layouts
Our Approach
Modifying windows and doors requires precise structural engineering, temporary supports (shoring), and proper flashing details. We verify load paths before cutting structural members, and use premium sealing techniques to prevent coastal draft and water leaks.
Stages of Planning & Delivery
Structural Shoring
Audit load paths, set up temporary prop supports (acrow props) to carry structural loads during cutting.
Cutting & Demolition
Cut existing framing or masonry, remove old window or wall structure, and install structural lintels/beams.
Framing & Install
Build new opening frames, lift window or door unit into position, align levels, and secure the unit in place.
Flashing & Trim
Install high-performance flashing tape, waterproof seals, exterior architraves, plaster internals, and paint.
Timeframe Factors
- Lead times for custom aluminium or timber window packages (subject to manufacturer scheduling)
- Need for structural engineering drawings and inspections
- Weather conditions during periods when exterior walls are open
- Matching old interior plaster and paint profiles
Cost Influences
- Material choice (solid timber frames vs thermally-broken aluminium vs double glazing)
- Size and weight of structural lintels (steel PFC/I-beams vs timber LVLs)
- Working at heights (requiring scaffolding or lifters if applicable)
- Asbestos containing materials inside wall cavities requiring disposal
Potential Risks & Delays
- Delays in window manufacturing causing project schedules to slip
- Rain during periods when exterior walls are open to elements
- Discovering termite or rot damage inside framing after stripping plaster
Byron Shire Planning Context
Coastal properties in the Northern Rivers are subject to strong wind loads and require high-performance flashing and weatherproofing seals to prevent rainwater leaks from coastal storms. Material selection is tailored to the site's exposure, design requirements, and engineering specifications.
Frequently Asked Questions
How long does it take to remove an internal wall?
Removing a non-load-bearing wall takes 1 to 2 days. A structural load-bearing wall removal takes 3 to 5 days, including setting props, installing a structural beam, framing, and plaster patching.
What is double glazing, and is it necessary?
Double glazing uses two layers of glass with an insulating gas gap. While not strictly required in coastal climates, it improves acoustic isolation and reduces thermal transfer, keeping your home cooler in summer.
Do you handle custom timber doors?
Yes. We source and install premium custom timber doors, including bifolds, pivot doors, and cavity sliders, matching existing architraves and skirting profiles.
