Customer reviews for GS Building Supply, a countertop supplier, present a mixed picture based on 14 separate testaments. Positive feedback frequently highlights their quartz selection, competitive pricing, good material quality (especially when compared to big-box stores), delivery efficiency, and mostly positive installation experiences performed by their own crews. They are also noted for having knowledgeable staff and customer service representatives. However, recurring negative themes include complaints about sink durability and quality (broken models mentioned), specific installation errors (incorrect leveling, mismatched shades, minor fit-up issues), inconsistent return/refund policies, and difficulties in getting timely help or proper follow-up after installation when issues arise. The range of customer experiences indicates variability in expectations, service quality, sink reliance, and durability concerns, alongside appreciation for certain product value.
