I only give them one star, because you can't go with a zero! We've been clients in Overijse Gamma shop for years, as we lived around the corner. They are probably at least 10-20% more expensive than some other shops, but they were a minute away from our house, and it was handy to go there. During the lockdown, I bought some items online,, as that was the only way to get something at the time. As the items were not what we needed, we tried to return them. Their very rude manager, Thierry, basically kicked us out of the store refusing to refund the items (that were returned fully in line with their return policy). I wrote to their customer service at least five times, called them numerous times since May, but never received a reply. Bottom line - they are good until you have a complaint. Then they ignore you. There's many much friendlier places to do your small overpriced items in Overijse and surroundings. My foot is never crossing any of their stores again.

Terrible store manager there, the arrogance is amazing. Zero competence in customer relations. Aside of him, the employees are helpful. Prices are expensive for brands. Prefer Brico Wavre.

Impolite cashier making a fuzz of a simple return.

Gamma is the store that is known for their nice employees, you can found a big amount over there of stuff for your home. I like also the interieur and often unique decor they sell

I can usually find what I want although I often have to hunt for it - some things are not always where I would expect to find them. Staff have recently become much more helpful, especially since the shop upgraded it communications systems. Worth getting a Gamma card for occasional discounts and looking on the website to see when the discount days are.

A well located building materials store with ample parking facilities. You'll find almost all you need for the basic building works, CONCRETE. FLOORBOARDS, PAINT, ETC. also a small selection of outdoor furniture and BBQ'S. Interior decoration items are not the speciality.

Big Gamma store however there are limited selections to some sections of their product as I often fail to find some stuffs that I was looking for. The price are good comparing to Brico. There are couple of staffs wandering around the store so if you need any help you can always ask them as they are friendly. If the products are not hanging at their assortment then you have to expect that they don’t have no stock of those products, meaning you have to wait for some other time to buy it (this situation happened to me many times).

Large DIY supermarket. Friendly service. Large parking. Prices OK.
