I finally found the right size chimney cap (size 7) for my chimney. My home inspector recommended it so I didn't get rain down my chimney. Cap looks like this:

Amazon.com: Vent Pipe Caps: BIC Superstore

I bought a tin one online for about $11 and last weekend, the boyfriend placed it on top of the chimney. Two days later, it was in my front yard. :rolleyes:

How do I secure this thing?

What did the BF to to attach the cap, hope it wasn't just friction.

There IS nothing to attach the cap. He just set in on the chimney. How are we supposed to attach the thing? We're n00bs.

A lot depends on the type of chimney you have. It could be metal, tile or brick. Tile or brick you slide the cap tube inside and attach with refractory cement or stove cement. If its metal there should be a small collar sticking up for you to screw into.

He's not sure what the chimney was made of. He thinks maybe fiberglass, or something similar. The cap could not fit inside the chimney. Are they supposed to fit INSIDE the chimney? I thought they were supposed to go outside of the chimney.

Any other ideas?

I'd like to try helping you but I need to know a few things first.

1. What type of material is your chimney pipe made of (at the top, where it's exposed to the sky)?
2. Is there any metal flashing around the top of the chimney and if so... does it contact the pipe itself?
3. Did your boyfriend attach it to the pipe or did he just set in on or in it?

Fiberglass? If it is a white plastic material, PVC is more likely. You should be able to drill some small holes and secure it with screws. If it is PVC, I am not sure you need a cap. It is only used with a condensing furnace that has a trap and a drain for the condensate, and a little rain won't hurt.

To determine if you really need a rain cap, post a question to https://www.askmehelpdesk.com/newthr...ewthread&f=150 giving all the details, type of furnace, chimney, etc. An unneeded cap could restrict the flow of exhaust gases messing up your efficiency. If you need help determining what you have, check the sticky, https://www.askmehelpdesk.com/newthr...ewthread&f=150 Some of the answers you get there should be from professionals that know what they are talking about.

I know this picture might be hard to see, but here's a pic of it. It's the highest thing on the roof.

1. I don't think the chimney is PVC. Pretty sure it's not metal, either.
2. there is no metal flashing around the top of the chimney.
3. and my boyfriend just set it on top; there's nothing to attach it TO.

That's my original question: how DO I attach this thing? It's just a tin chimney cap. Nothing substantial.

We tried to size 6, but it wouldn't fit over the chimney. The size 8 was too big.

Sorry Callisto9 but I don't see your picture. Where did you attach it in the post. It can not just sit on top. Gravity and wind.

Sorry! Edited post.

Still don't see it but it could be me. Good with tools , not so good with Dell.

The picture is too small for me to tell much. It looks like type ''B'' metal to me. It certainly doesn't look like the small PVC vents the high efficiency condensing furnaces use. Whatever it is, I don't think drilling a few small holes and running a screw in will hurt.

ballengerb1 · Apr 10, 2007, 12:18 PM

Got your pics, liked the red tape on the toilet. Still can't tell what material it is made of but I'm guessing your BF can try to sheet metal screw through the cap into the material. Your can buy 4 -5 self tapping sheet metal screws and try that.

LOL yeah, the house doesn't look like that anymore. Please tell me you looked at the current pics, too. ;)

I'll try the sheet metal screws. Thanks. :D

I looked at them all. Bet that foundation cost a pretty penny. Are you staying in this place or flipping it. It looks like a great flip. Sell it, buy another and keep moving up with reinvesting the profits. Painting and landscaping increase the value a lot but kitchen and bath are the buyers prime concern.

I didn't pay for the foundation, the bank did. It was $2700.

We are staying in the place. I didn't buy it to flip it, I bought it 'cause it was the only decent house I could afford! ;) we'll be there at LEAST 5 years. I really wanted a home to live in and enjoy, not flip. Although yes, it's a prime property to do so.

Hello-

I am not sure if you got an answer on this question but if I am seeing the picture correctly then I think you just have a metal vent pipe coming through your roof. If so, you probably are putting some type of vent cap on it. If that is the case then just use construction screws or metal screws that are self drilling. Make sure they are good for exterior purposes. Most likely you will only need 2-4 of them based on the size you mentioned. This should prevent the cap from blowing away.

Good luck! :)
