The most commonly mentioned themes are product quality, customer service responsiveness, delivery experience, and after-sales support. Customers praise the straightforward ordering process and the ability to self-install, as well as communication during fulfillment. On the negative side, there are recurring complaints about receiving items in poor condition, inconsistent quality control, unhelpful staff, and delays in rectifying issues. Some reviewers explicitly warn others to avoid the company after repeated negative encounters.
In summary, Modern UPVC Windows earns praise for ease of ordering, value for money, and friendly staff, especially for PVC windows and doors. However, recurrent quality control issues and customer service shortcomings limit its overall reputation, particularly for buyers in need of faster, more reliable problem resolution. The company is regarded with caution by customers in its service regions.
