Green Building Store products are often my first choice – not just because they offer excellent products but because their customer support and aftercare is second to none.

Your lock team did a lovely job yesterday. They arrived on time and worked solidly and very carefully for several hours to achieve the level of perfection needed.

Alex Jowitt – Client

Unfortunately we had some damage to the windows during installation (NOT installed by Green Building Store’s own fitting team but by another installer); fortunately they were easily repaired. Green Building Store’s AfterSales team were excellent and helped adjust all the external doors within tolerances. We really got the feeling that Green Building Store were on our side and batting for us. They have been a nice bunch of people to deal with.
