Yes, you might get your windows replaced for free or at a very low cost through government programs like the Weatherization Assistance Program (WAP), which targets low-income households, seniors, and people with disabilities to improve energy efficiency, though funding can be limited, and you'll need to meet strict income guidelines. You should also check for state-specific programs or rebates for energy-efficient upgrades, but be wary of ads promising completely free windows, as they might be scams or part of legitimate programs with hidden requirements.
The Help to buy Windows Scheme is committed to helping those in need to improve their energy efficiency and lower their energy bills through the installation of high efficiency double glazed windows and doors.
