Third, if the air leakage problem of aluminum alloy doors and windows is caused by inadequate installation of doors and windows, you can contact the merchant or directly contact the manufacturer, generally, door and window manufacturers with strong brand Foundation will have a special after-sales problem solving team, and can contact the merchant to apply for after-sales maintenance. If it is the master's problem, you need to remove the doors and windows and reinstall them.

In this case, we can carefully check out the damaged parts and contact professionals or skilled personnel to replace them. It is worth noting that the parts must be replaced regularly and cannot be replaced until they are completely damaged, this is very unfavorable to the service life of the entire door and window.
