How do I line an Old Chimney?

Question

I'm an engineer and the price that they're asking is madness. Any advice would be helpful as I would like to undertake the work myself. I'm aware that it will take quite a bit of effort which I don't mind.

Answer 1

there are different types of liner for what fuel your using , class 1 is for multi fuel, eg gas , wood , coal , that's the best to use ! class 2 is just for gas , and if this is for a fire you cant use less than a 7 inch liner due to regulations unlike what these other Muppet's are saying ! you will need to get a nose cone either 7 or 8 inch depending on size of liner which you can get on eBay ! if not try a company like chimflue . attach the nose cone with pk screws to the liner ,on the liner you usually have an arrow indicating the way up the liner should go down, the arrow shows which way the smoke should flow out the chimney ! put a rope and weight on cone and and feed down the chimney till it hits bottom , 1 person pulls from below and the other one feeds on top , sometimes its easy and other times its a nightmare depending on how tight the sets are {bends in chimney } if your going onto a gather at the bottom you will need a 1ml thick gather if its solid fuel , any more questions just mail me !

Answer 2

As you will have gathered, metal chimney liners, which are reasonably flexible and are corrugated like vacuum cleaner hoses, are available in various diameters, but they aren't cheap.

Two suggestions:
1. Before spending any money, mock up a short cylinder out of something or other, same diameter as the liner you think will do the job, and try lowering it down the chimney. If it won't go down because the inaccessible parts of the flue are narrower than you thought, you won't have wasted money on a liner which is too large. Having a line hanging down from the cylinder to the fireplace can help -you and an assistant can then try a bit of jiggling to get past obstacles. Use sturdy line - you don't want it to break and leave the "go" gauge stuck.
2. Cut out one of the bricks on the outside wall and fit an airbrick to ventilate the space around the new liner - otherwise, dampness can gather.

Here's a third tip - leave the job until spring - winter's coming!

I was going to do the same job myself and decided to sweep the chimney first before ordering materials. Good job I did, the brush could hardly get up through the chimney let alone a 100mm chimney liner. I abandoned the plan and used the old chimney for my wood burner. Still OK 6 years later when I sold the terraced house.

the liner is stainless steel it comes packed according style first measure the length you will need go on the roof and drop down a hose have someone in the basement .when the hose is even with the top of the chimminy have them mark the hose where it mets the flue for the furnace/hot water stack .now measure the length also if the chimminy is 8 inches across then use a 6 inch now .unpack the liner a pull out the required length [it takes a bit of work tie the rope to the bottom of the liner .go back on the roof and lower the rope to some one in the basement and as he pulls on the rope you feed the liner down the chimminy you fasten the liner at the top and reinstall your cap .mean-wile in the basement you fasten the liner and install a Wye pipe and to this Wye you install the furnace and hot water flue pipes.the liner cost about 75.00 for a 25 foot section .if you need more than 25 ft add another .they clamp together easily

Answer 5

very easily done with a flexible metal liner that resembles a metal vent for a drier. Only this is heavy duty metal and is installed through the chimney with use of a rope and another person feeding the liner up through the chimney to you. set of fittings and cap etc available at any wholesalers where the guys doing furnace and A/C installations get their parts from. Just make sure that size is what you need to do job. Talk to desk people as to what it is for ...IE: gas fire, boiler whatever and the BTU size and the height of chimney is needed too, to get sizing done properly...

Answer 6

hardware stores have chimney liners. Measure how much you need. go buy it. First, connect the Last piece to the chimney top and set aside. then stick the chimney lining pieces together (use aluminum tape to help hold them together) insert them down the chimney. Then connect the last piece with the top to the the rest already in the chimney. It just sets in place and relines your chimney. Almost always requires 2 people.
