We know our stuff! Read our customers stories...

I just wanted to share all our team's thanks here at Shindigger by saying that you guys did a truly amazing job on a brewery warehouse. Again, a big cheers for your help to move and expand the room we have for storage. As always it's a pleasure working with Coolmark. I'm looking forward to working with you on the next expansion.
George @ ShinDigger Brewing
Your company's quick response and impeccable organisation skills are an asset to us and all customers who use you. We really appreciate how you turned an empty space into a walk in cold storage facility with just a days notice. We were able to open our newly refurbished premises without delay. Amazing!
Lawrence @ Cheshire Estates
Another perfectly designed, organised and installed cold room for us. Let your guys know they did a fabulous job. I think it's great we can rely on you to sort electrics, building work and temporary storage. This saved us organising multiple contractors and managing timelines. Alltogether Excellent!
Andy @ KBK
You and your team are the dogs *******! Our new walk in freezer is exceptional. Thanks for maximising the storage, completing quickly so we could stock up, organising everything without a glitch and most of all for your personable character. Quality job well done .

I would like to congratulate all at Coolmark on a sterling job building the walk in freezer for our customer. The technical work you did on recovering the waste heat from the freezer system and using it to heat other areas of the building is remarkable. All the very best wishes to you in your ventures.
