If you want an efficient fireplace, I recommend a full insert (sealed-combustion) that runs a new vent pipe, typically up your existing chimney. Hire a professional installer from a local fireplace company to do this. 

There are also options to retrofit a "gas log" in an existing fireplace, but there are several issues with this. Typically, if you have an open hearth without doors that seal tightly closed (with a gasket) then you are going to put more energy up the chimney than actually radiates out into the room.

Brick mason

Both, more than likely. The mason should replace the masonry products and the roofer should work with the mason to achieve a regletted counterflashing and flash the roof under counterflashings.

There are a very wide veriety of gas fireplace inserts.  

1. Check with the city to see what you can install.  Some cities are now requiring sealed units

2. Do not try runing a gas line by yourself.  Hire a licensed plumber to do it.

3. http://www.csia.org/?gclid=CL_Qk-SZ0dACFZBefgodOrUNRA Contact a CSIA certified chimney sweep to help you install.

I would recommend a licenced mason   Please don't have a handyperson do it.  It will look terrible and may not withstand an siemic even properly.

i would call some of the licenced home builder in your area and ask them who they would recommend/

Masons would install mortar on bricks.

Metal roof pricing ranges on what the structure details are (steepness, valleys, penetrations, wall flashings, chimneys, etc.) and what gauge, profile, ventilation and snow retention (if any) is needed or requested.

You're not looking for a brick mason.....your looking for a landscaper expirenced in hardscapes.....brick masons typicall only deal with installing brick facades.....pavers require grading,fill material (compacted correctly), and then paver install....not something a mason would have knowledge of...

Yes, we almost use Thermory exclusively now. The product is amazing and I really cant think of any negatives as opposed to Ipe that shrinks and is super heavy. We just used Thermory on our own home.

We located in Hermitage, TN.  Same county (Davidson) as Nashville.

There are  two sections we need to fill:  one is 17' x 6'.  The other is 9' x 8'

See attached photos.  Obviously a small job, which might be too attractive to masons.

Donald, 

Where is your townhome located? We are located in the Charleston, South Carolina area and would be happy to refer you to high quality masons. Since masonry contractors vary by location, we would also recommend using GuildQuality to search for a reputable Brick Mason in your area.

Best of luck with your outdoor living project!
