    ASQB has completely transformed the comfort of my home. When I moved into my 1920s apartment, its 13 beautiful timber casement windows had suffered many years of neglect. The hinges were badly rusted, the windows would not close properly, and my home was exposed to cold draughts, road noise, dust, dirt and water ingress. Sean, Steve and Tim repaired the windows with exceptional skill, installing Q-Lon seals and new hardware while carefully preserving their original character. The difference is extraordinary. My apartment is now warm, quiet and properly sealed, without compromising its beautiful 1920s aesthetic. Beyond their expertise and craftsmanship, Sean, Steve and Tim were exceptionally courteous, respectful and professional. They were genuinely lovely people to have working in my home. I cannot thank them enough. Their work has not merely improved my windows; it has transformed my enjoyment and quality of life. I recommend ASQB without hesitation.

    Sean and his sidekick from ASQB replaced the seals on the aluminium sliding windows and fixed the patio sliding door in my strata unit. He was fantastic taking the time to carefully fix all the seals. The windows are the older style type and had not been well maintained- so I was delighted when he finished and the windows and door could easily open and close. He also took the time to clean up after he finished the job. Very professional and would highly recommend.

    Frequently Asked Questions

    Whether or not window repairs are covered by your strata scheme depends on your specific by-laws and the nature of the damage.

    Generally speaking, strata are responsible for repairs to common property windows, while individual owners are responsible for windows within their units.

    Similar to windows, responsibility for front door repairs depends on whether the door is considered common property or part of an individual unit.

    In general, strata are responsible for the external door and frame, while the owner is responsible for the internal door and any damage caused by them.

    Responsibility is typically outlined in the strata scheme’s by-laws. Again, generally, the owner is responsible for repairs within their unit, while the strata corporation is responsible for repairs to common property. All windows within a unit fall under common property, unless a by-law has been introduced, by the executive committee, that places the responsibility of windows onto the individual owners. But this is not the norm.

    We have expertise in a wide range of window and door types, including:

    • Window Styles: Awning, casement, double-hung, sliding, louvre, and more.
    • Door Styles: Sliding, French, bi-fold, entry, patio, and security doors.
    • Materials: Steel windows, timber and aluminium.

    Our team can provide expert advice on selecting the most suitable windows and doors for your specific needs, considering factors such as energy efficiency, security, style, and budget.

    We service the Greater Sydney area, including the Eastern Suburbs, South-West Sydney, North-West Sydney, Western Sydney, Lower North Shore, Northern Beaches, and Inner West.
