Gas Fitter

Gas fitting involves the installation of natural gas lines in homes and other commercial buildings. Greg MacDonald will inspect your premises and figure out the materials needed to proceed. Installation of gas lines is followed by the installation of related equipment, including meters, valves, burners, etc. After all equipment is installed, we will continue to maintain and repair the equipment.


After every job we will maintain all equipment to ensure everything is working and functioning correctly to ensure you and your home are safe.

Certified Backflow/Cross Connection

Backflow is when water flows backward from its natural flow, causing the contamination of drinking water. Using backflow prevention equipment, Greg MacDonald can prevent any water contamination to ensure your water is clean and safe. We ensure there is no cross connection between process pipes, which may have the possibility to interfere and contaminate the pipes carrying your clean water.
