The most frequent criticism relates to poor manufacturing quality and durability of Solidor composite doors—several customers describe significant defects such as bowing, misaligned facings, split materials, and corroded fixtures. Attempts to resolve these problems through official channels are often met with blame-shifting or limited cooperation, despite visible issues like failed locks and doors that cannot open. Positive feedback is largely limited to one trade customer who emphasizes the importance of installation by approved fitters and investments in manufacturing practices.
Overall, Solidor holds a poor reputation for reliability in the UK, especially among residential customers who expect higher standards from premium-priced products with warranty coverage. While there is some recognition of improvements in support and ongoing investment on the trade side, the dominant narrative from reviewers is consistent underperformance, recurring defects, and unresolved customer concerns regarding basic product functionality.
