"He started great, but went down hill. 5 months to install a new heating system after being told it was 5-6 weeks.I was told he had no idea when he could finish because he started a 92 unit condominium project. On another project they installed an HVAC system with no control board. Lied to continuously about dates. We paid in advance for the work and found out afterward that he fired half the staff (I now know why.) Rather than be upfront about the issues he was facing we told lies. Very frustrating and found Devin to talk like an excon. Say one thing and do another with a very straight face."

Gas Leak Repair questions, answered by experts

No, homeowners should never attempt to fix a gas leak themselves. Gas leaks pose serious health and fire hazards. Exposure to leaking gas can make you sick, and accumulated gas can ignite and explode. So always take leaks seriously and seek the help of a pro right away. While you may be able to detect a gas leak, always call a licensed professional to handle repairs and replacements.

If you think your home might be experiencing a gas leak, you should immediately leave your home and call a professional natural gas line plumber for assistance. Natural gas is dangerous and highly flammable, so you shouldn’t stay inside your home if you think there might be a gas leak.

In most cases, a flexible steel hose connects your gas line to the wall. This process is typical if you are replacing your gas stove or if the old pipe has worn down. However, always leave this job for a professional plumber. Errors can be very dangerous, so it's worth calling a professional to take a look.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Any gas pipe can leak, especially if it’s old or isn’t properly maintained. However, even with a shovel, plastic pipes are more easily damaged by impact. That’s why it’s so important to have gas lines marked by the utility company before you begin digging for any reason. Some metal pipes, like black pipes, galvanized steel, and copper, aren’t as easily damaged by impact but can degrade over the years, leading to leaks.
