What Our Clients Are Saying About Us » I would like to recommend your company to anyone November 13, 2020

Your company KDM Home & Gas has just installed the CV 50 water heater to my house. The installation process was so smooth. You guys put on the carpet runner in order to avoid any scratch and damage to the carpet and the floor. Your professional guidance has highlighted the B Vent should be installed for the chimney exhaust in order to comply with the building & safety code. You have even performed leak test & dial test in order to make sure the whole installation is in a perfect manner. The registration of the warranty is also very convenient and easy.


I really appreciated that you came to my house to inspect the situation and provide the quotation to me before we decide to get the new water heater. The whole process was so smooth and communicate very well. You return all my text message on the same day basis or even within short time. I would like to recommend your company to anyone.

Don GibsonMarkham, Ontario I would recommend this company to anyone who is looking for a professional job at a reasonable price November 13, 2020

KDM did a very professional job paying attention to safety and TSSA codes for this type of work. At the end of the job they tested all gas fired appliances as they had the main gas off to preform this job, and made sure everything was working proper.


I would recommend this company to anyone who is looking for a professional job at a reasonable price.


Don BlakeWhitby, Ontario I would recommend KDM Home Gas to anyone looking for quality home repair services November 13, 2020

Daniel was really great to work with. His communication and genuine care for the work being done made all the difference in the world to me especially as we’ve never had good experiences with contractors in the past.


Daniel showed up when he said he would, and took his time to explain to me what caused my humidifier to malfunction. His customer service skills are superior and his quality workmanship made the experience a pleasant one.


I would recommend KDM Home Gas to anyone looking for quality home repair services to their heating or cooling units.

Frank HowardWhitby, Ontario I would recommend KDM Home & Gas to anyone looking for great service at a good price. November 13, 2020

After our old (20+ years) unit gave out, I used HomeStars to obtain quotes for a replacement. Within 30 minutes of posting, I was speaking with Daniel, who was polite and helpful throughout the process. He offered a fair price and a few different products to choose from, and was able to do the installation the same week. I would recommend KDM Home & Gas to anyone looking for great service at a good price.
