   We recently had air conditioning fitted in our office. Engineer Billy came out and inspected and a quote was received the same day. Marie, in the office, was really helpful in organizing for the air conditioning to be fitted ASAP, and Billy and team were back out less than a week later to fit the goods. Really impressed with the quality of service we have received from Kassgas, Billy, Marie and team have gone above and beyond to answer all our questions and made sure everything happened swiftly and efficiently. Would highly recommend.

   Fantastic service from start to finish. I spoke with Matt and booked our annual bolier service, he was extremely helpful and accommodating. Billy arrived to carry out the service, what an absolute gent, really polite and explained everything, he was extremely helpful with a number of questions I had. We were sceptical about using a different company, I'm so glad we did, can't recommend these guys enough. Thanks again to Billy who removed any concerns we had.

   I first came across the lads at Kassgas about 18mths ago, when I hired them to remodel my master en-suite bathroom. Their attitude, knowledge and standard of work was truly exceptional. Since then, I had them back earlier in the year to upgrade my air source heat pump, radiators and UFH. Again, they were faultless. Despite my old property throwing problem after problem at them, nothing seemed to fazed them, they rolled their sleeves up and got on with it. Fast forward to 3wks ago when I had them back for the third time, to remodel the downstairs guest bathroom. I gave Matt a picture from Pinterest as a guideline and he project managed it from start to finish, down to the smallest of details. Billy and Chris who made the plans a reality, truly are masters of their many trades and constantly went over and above it implement only the highest of standards. I highly recommend them, please enjoy a few photos of the latest project.
