"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."

I had planned to work a half day from home but ended up working the whole day from home. (I am fortunate that my employer is flexible.) Other than that, everything was great. They were professional, friendly, did good work, put down a tarp to protect my laminate flooring, and cleaned up after themselves. I would recommend them to others and would use them again."

Gas Leak Repair questions, answered by experts

In most cases, yes, it’s safe to light a gas water heater manually, but you should shut the gas off first, open a window, and let the space air out for about 10 minutes. Modern water heaters shut the gas off entirely if the pilot light goes out, but airing out the area beforehand is good practice and will ensure it’s safe to relight your pilot light manually. Just make sure you turn the gas valve to “pilot” before lighting. If the light keeps going out or won’t light at all, call in a professional.

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Temporarily capping a gas line—for renovations or during travel—doesn’t require a permit. If you plan to remove a gas line and cap it completely, you’ll need to apply and pay for one through your town or city. Depending on your region and its local codes, you may pay between $25 and $100. To avoid a gas leak or other hazards, some cities take the job of permanently adjusting or capping a gas line out of the hands of homeowners. Instead, they require hiring a professional gas plumber.  

Renovation projects that require moving a gas-powered appliance may also require moving the gas line that supplies it. The cost to move a gas line falls between $375 and $750 and will depend on how far the line needs to be moved, the cost of the permits, and how much excavation is needed, along with other factors. 

Shut-off valves, like any other piece of metal hardware, can corrode, age, get worn down, and eventually break or rust into place. Occasionally spray your shut-off valve with WD-40 to stall it from rusting. If it really gets stuck, a wrench and WD-40 will usually do the trick, but you will need to call a plumber if it’s completely unmovable.
