Now that they've completed the job at my house, allow me to provide yet another glowing review. Chris and I connected not long after my request for a quote and he came by my house in the next day or so. After spending a little time in the attic, he came down to give a thorough breakdown of what was in the attic and a couple of different paths I could take (e.g. removing all the existing insulation before blowing in the new product; leaving the existing insulation and simply blowing the new stuff over the top of it). He answered every question I asked and had a formal estimate (which included detailed photos of what he saw up in the attic) to me the next day. Chris promised that the team coming to do the install would be top-of-the-line -- and he was right. Dave led the crew, who were very respectful of my house and used floor coverings and booties throughout the installation. They removed all the old insulation and got the new stuff in place in about 3 hours. Dave had me inspect the work before departing and was also happy to answer a couple of follow-up questions I had. I wouldn't hesitate in calling Chris if you're in need of assessing your insulation situation or are ready for a replacement. As many folks on here will attest, you'll get outstanding service from start to finish.

Be CAREFUL! Very friendly owner has apparently retired. Now…read morethe fireplace Chimney.com sold has failed after just 2 seasons. The problem is not our pilot or gas, it's the solenoid gas valve part that Chimney.com installed. (A master plumber has identified the issue 100%, but doesn't do gas repairs.) Since the whole device is controlled by remote, we know we did not break it--we never touched it ever, but the like-new fireplace did not come on this year. We were charged full price for the unit, which should have lasted for many years. Now Chimney.com is now wanting another $300 just two years later to repair. Paid a lot for a new unit. Chimney.com they says they are not responsible for quality of their products and will charge for labour to "evaluate" the issue. They act very folksy/ocal--until there's a problem, then they cut you loose. Be forewarned that you need to be lucky because they don't stand by their products sold. This feels scammy.

After…read moresearching Virginia, DC and Maryland for a reliable gas fireplace seller/installer, I was referred to Tiffany and Jimmy. This company had every other beat in terms of price and service by a landslide. First, their prices are significantly lower than the competition as they have their own gas fitters and electricians. Most other companies contract out this work which adds a lot to the cost. They also have a beautiful showroom where you can see fireplaces before buying. Second, the service was unparalleled. Every single step was carefully explained and communicated. The technicians were on time, pleasant, careful, clean and skilled. It simply could not have been a better experience. This is a company that provides old-fashioned standards of excellence at incomparable prices. You will not be disappointed if you are lucky enough to do business with them. I consider it a tremendous stroke of luck that I had the good fortune to find and work with them. I think you will, too.
