Professional Window & Door Installation & Replacement In Melbourne

A building permit may not be required for a like-for-like replacement where the opening remains unchanged and no structural work is involved. Changing the size of an opening or modifying structural elements may require approval, while planning or heritage controls can also apply. Check with your local council or building surveyor before work begins. Our team can also guide you on what checks you may need to consider.

A straightforward single-window or door installation may take several hours, while a project involving multiple openings may require one or more working days. Larger configurations, restricted access, structural alterations, repairs around the opening and weather conditions can extend the schedule. The selected styles, glazing and level of preparation required can also influence timing. A more accurate estimate can be provided once the property, openings and project scope have been assessed.

It may be time to replace your windows or doors if they are difficult to open, allow persistent draughts, have damaged frames or show moisture between the panes. Doors that no longer close securely, drag against the frame or have deteriorating seals may also need attention.

Rising outside noise, visible corrosion or repeated repairs can indicate that the existing products are no longer performing as intended. For timber systems, peeling paint, swelling or decay may make a lower-maintenance aluminium replacement worth considering. A professional assessment can confirm whether repair is still practical or replacement is the more suitable long-term option.

Professional installation helps ensure each window and door is measured accurately, fitted securely and installed in line with relevant requirements. This supports smooth operation, effective sealing and the intended performance of the complete system. It can also help preserve applicable warranty coverage, as Dowell’s limited warranty is subject to specified installation and maintenance conditions.

Curtains, blinds and other window coverings should be taken down before installation. Dowell does not usually remove or reinstall these items, as existing brackets or fittings may need to be repositioned to suit the replacement window. If you need help with this, please speak with our team before the installation date.

Painting is not typically included with the window or door installation. Where architraves are installed, our team will fit them, fill the gaps and leave them ready for sanding and painting. Any additional carpentry or finishing work included will be clearly outlined in your quotation.

Unless your quotation states otherwise, our team will remove the existing windows, doors, glass and installation waste from site for appropriate disposal. If you would like to keep any existing products or hardware, please let us know before work begins. Keep in mind that some windows and doors cannot be removed intact and may require additional work that can cause damage during removal.

The installation process will vary depending on the existing opening, wall construction and replacement product. In most cases, the old window or door is removed, the opening is checked and prepared, and the new unit is carefully positioned, levelled and fixed in place. Trims, seals and other finishing components are then added before the product is checked for smooth operation, appearance and weather protection.

Flexible foam is also applied within the gap between the window and the house frame to help support acoustic and thermal performance. Dowell follows relevant AGWA-recommended window installation practices throughout the process.

Before our team arrives, please remove curtains, blinds and other window furnishings and clear furniture, decorations and fragile items away from the work area. Installers will need safe access to each window or door from both inside and outside the home. Children and pets should also be kept away from active work areas. Please advise us beforehand of any access restrictions, alarms or other site requirements.

You do not need to stay home for the entire installation as long as suitable access has been arranged in advance. However, it is helpful for you or an authorised representative to be available when work begins and again at completion, so any questions can be addressed and the finished installation can be reviewed and signed off.

The changes you notice will depend on the windows and doors selected. New products may provide improved comfort, reduced draughts, smoother operation, better security and an updated appearance. Where single glazing is replaced with double glazing, you may also notice reduced heat transfer and outside noise. Results will vary depending on the glazing, frame system and the broader insulation and ventilation of the home.

Installation materials are selected according to the window or door system and the construction of the property. Depending on the project, Dowell may use suitable fixings, packers, flashings, sealants, trims and other components required to securely install and weatherproof the opening. The materials used will be chosen to suit the specific product and site conditions.

Older windows may have little or no external surface sealing around the frame. When replacement windows or doors are installed, the external perimeter is finished with suitable trims and silicone sealant. Flexible foam is also applied around the frame where required, helping create an additional barrier against unwanted air and water movement while reducing heat transfer around the opening.
