These guys do fantastic work!!! Custom designed/fabricated a single-piece stainless steel chimney for our Bosch hood vent. We have a vaulted/slanted ceiling and wanted just a single piece instead of the two-piece chimney that came with the vent. Very happy customer.
Ordered my second microwave trim kit from Microtrim. The 1st was about 13 years ago. The 2nd was just a few weeks ago. Lead time was like a week... it arrived to my door fast. Easy installation using well-thought-out instruction sheets. I'm very happy with the results.
Replaced old 30” island cooktop with a new one. Had a larger rough opening than anticipated so I looked around on the internet and found this company. Sent them the cooktop measurements and requirements per the manufacturer manual and ordered a trim kit. Arrived in about a week and installed. The trim kit is awesome! Looks great! Just be aware that the trim kit does not support the weight of the cooktop. I was told this when I ordered so fabricated some under counter supports. Ordering was simple. Highly recommend!
I purchased stainless steel trim for my island range/oven. Company was very helpful in answering questions and making sure details were correct. They were familiar with the specs of my oven, resulting in a detailed trim piece with cutaways that fits well.
An appliance dealer recommended Micro-Trim to fill a uniquely shaped microwave cutout in our kitchen. The measuring and ordering process was easy and intuitive, and the custom trim fits perfectly. We are very happy with the product!
