    Midori were competitive in price, I had great service from the sales team and a flawless finish from their in house fitters, what was a really nice surprise was the after sale service. I can’t speak highly enough of the business overall. It was end to end easy which in the building trade is rare.

    Honestly had such an amazing experience with Midori Aluminium – couldn’t recommend them enough. For something I wasn’t that knowledgeable on myself, they made me feel like I was in very safe hands with very high quality work and expertise in their field. The communication was so easy and kind and I am so happy with the results!

    Absolutely delighted with the work by Midori. We have an old converted barn and Midori replaced an old wooden coach house doorway with aluminium bifolds and arched window above. The team were fantastic and we are very happy with the results.

    Can’t say enough about Midori Aluminium. From the first time I contacted them I knew I was in good hands. We were looking to get our porch and front door done. They were professional, we went into the showroom to have a look their doors/windows, they then came out, measured up and sent us all of the designs in a few days. The service was amazing and it had that personal touch. They took interest in all of the detail as if it were their own project and made sure we were happy.

    Vanisha and Vijay were amazing throughout and we were really pleased with the outcome. I will definitely be recommending Midori to everyone I know. Thanks Midori!
