Older windows and doors may have air leaks and insufficient insulation, which can allow heated or cooled air to escape and outdoor air to enter your home. This can cause your heating and cooling system to work harder to maintain a comfortable temperature, resulting in higher energy bills.
By replacing your old windows and doors with new, energy-efficient models, you may be able to reduce the amount of air leakage and heat transfer, which can help to lower your energy bills. In addition, some energy-efficient windows and doors may qualify for tax credits or rebates from government or utility programs, which can help to offset the cost of the replacement (Our windows & doors do!)
