Using cool masters has been a life saver! Edwardo explained everything in detail and completed the repairs in a speedy fashion! Pleasant to work with and always reviews my options.

We’ve used Cool Masters on 3 occasions in the past 3 weeks and each time we are blown away by their service and attentiveness. Eric is so professional and caring. Worked in the cold for a whole day to fix our pipe, wouldn’t leave till it was done. Chris was also amazing fixing a faucet/pipe issue we had. Very knowledgeable and friendly. Even got the air out of the lines after reconnecting the water. As far as pricing the quote given up front was the perfect ball park for the repairs.

Couldn't be happier with our experience with Cool Masters. Eric and Chris were great - communicated well ahead of the appointment, arrived on time, and we really appreciated them walking us through everything before they started. They helped us repair a problem with a sump pump and basement ventilation that we had been dealing with for a few months after another company we're not able to solve it for us. Eric and Chris diagnosed the issue and completed the work in a few hours and it's been a week now and the issue has been fixed. Their work was high quality and very neat. We'll definitely be working with them again in the future.
