Our propane service gave Double L as referral regarding a leak. It's always scary to call a service that you don't normally use and you hope you get a good, honest and competent company. Double L is all of those things and more. They've been very accommodating with our schedule and even threw in some humor when the situation turned out to be worse than anticipated. They still have much work to do but I have no complaints and I know the job will be completed in the best and safest way possible.
