Professional Window & Door Replacement & Installation In Victoria & Tasmania

A building permit for windows and door installations in Victorian and Tasmanian properties may not be required for a like-for-like replacement where the window or door remains a similar size and no structural changes are made. Altering an opening or modifying structural elements will generally require approval, depending on the cost of the project, while planning or heritage controls may also apply. Check with your local council or building surveyor before work begins. The team can also guide you on what checks you should consider.

A straightforward single-door or window installation in Hobart, Tasmania, or Victoria, Melbourne, may take several hours, while projects involving multiple openings may require one or more working days. Larger configurations, difficult access, structural alterations or repairs to the existing opening can extend the schedule. A more accurate timeframe can be provided once the property, product selection and scope of work have been reviewed.

Double glazing uses two panes of glass separated by a sealed space to help reduce heat transfer through the window. When appropriately selected and installed, it can improve indoor comfort, reduce heat loss and support more efficient heating and cooling. It may also improve acoustic performance, depending on the glazing, frame and complete window system.

Common signs include damaged frames, persistent draughts, deteriorated seals, difficult operation or moisture between the panes of an insulated glass unit. Flaking paint and decaying timber may also be a sign to consider aluminium replacement frames. Replacement may also be worth considering when the existing design no longer provides suitable security, ventilation, natural light or functionality for the space. A professional assessment can help determine whether repair or complete replacement is the more appropriate option.

Blinds, curtains and other window furnishings should be removed before installation begins. Dowell does not generally remove or reinstall these items, as brackets and fittings may need to be adjusted to suit the new window. If assistance is required, please discuss this with our team before installation.

Painting is not generally included as part of the window or door installation. Where new or existing architraves require painting, this will normally need to be completed by the homeowner or a qualified painter after installation. Any carpentry or finishing work included by Dowell will be clearly identified in the quotation. All architraves are installed, gap filled and ready for sanding and painting.

Unless otherwise stated in the quotation, our team will remove the old windows, doors, glass and installation debris from the property for appropriate disposal. If you would like to keep any of the existing products or hardware, please let our team know before installation begins. However, not all windows and doors can be saved, and removing them may require additional work and could damage them.

The installation method depends on the existing frame, wall construction and selected replacement product. Generally, the old window or door is carefully removed, the opening is inspected and prepared, and the new unit is positioned, levelled and securely fixed. The perimeter is then sealed and the required trims or finishing components are installed. Finally, the window or door is checked for correct operation, appearance and weather sealing before the work area is cleaned. A flexible foam is then used within the gap between the window and house frame for acoustic and thermal benefits.

All window installations meet and exceed AGWA’s recommended window installation methods.

Before installation, please remove curtains, blinds and other window furnishings and move furniture, decorations and fragile items away from the work area. Ensure installers have clear access to each window or door, both inside and outside the property. Please keep children and pets safely away from the work areas and let our team know about any access restrictions, alarms or other site-specific requirements before installation begins.

You do not need to remain home for the entire installation, provided access has been arranged with our team beforehand. However, we recommend that you or an authorised representative is available at the beginning of the installation and again at completion to discuss any questions, review the finished work and complete the required sign-off.

Depending on the products selected, you will notice improved indoor comfort, fewer draughts, easier operation, better security and a refreshed appearance. Double-glazed windows and doors will also reduce heat transfer and outside noise if single-glazed units are being removed. The level of improvement will depend on the glazing, frame system and the overall insulation and ventilation of your home.

The materials used depend on the selected window or door system and the construction of your home. At Dowell, we use suitable fixings, packers, flashings, sealants, trims and other installation materials required to secure and weatherproof the product. Materials are selected to suit aluminium, uPVC or timber systems and the specific installation requirements of each opening.

Your current windows are unlikely to have external surface sealing in place. Once the replacement windows or doors are installed, the external perimeter will be finished using appropriate trims and silicone sealant. Combined with our flexible foam application around the frame, this creates an additional protective layer that helps prevent water and air from flowing into or out of your home and significantly reduces heat loss or heat gain around the outside of the window frame.
