What Our Customers Say about us
Hear from our satisfied customers about their experiences with Builders Megastore.
Builders asked me to order some Self-Levelling so i found Builders Megastore online due to there very competitive prices. Even my builder was shocked at how cheap and quick it came. Thank you Bex at Builders Megastore.
Builders Megastore contacted me straight away and organised a fast delivery to our site. Fantastic!
Was about to place an order online but then decided to ring instead, the gentleman i spoke with (Mike) was very patient and helpful to me. Glad i called them as they really put my mind at ease. All products turned up on-time and undamaged.
Great company to use, fast delivery on this product and was cheaper than everyone else. Thank you
