Best Jack For Floors

I'm looking for a good jack for sagging floors and house lifting.

I have several beefy big red bottle jacks, but mine sink over the hours/days under load, perhaps I need to bleed them, not sure.

Does anyone have a house lifting jack they recommend that's better than a bottle jack? I was thinking an electric/hydraulic, but I'm having trouble finding the jack I'm looking for.

Do a search for shore/shoring jacks.

I agree with tom

Search for “post shore”

I am own Several and their great because even with weight on them you could slowly tap them up to make adjustments

I raise the roof of a guys garage with them to fix a sagging garage door header

Here is a picture of them holding up my house so i could rebuild my foundation

Re: Best Jack For Floors

all depends what you are trying to do...

with what kind of materials...

and under what conditions...

difficult to find a one size fits all...

could be more efficient to hire a guy who does it all the time...

just depends...

Re: Best Jack For Floors

I assume you are talking about jacks for a short time, while repairs are made.

We have several old fashioned bottle jacks.

They work good and never bleed down. I bought them used for $25 each. Mine are really old, but they never wear out.

If it is for permanent use, a basement jack is your only option really. I prefer the ones that are one piece tube. They come in several sizes and can be cut down if needed. I just don't like the 2 piece ones, but I'm sure they perform up to their rating, just fine.

Re: Best Jack For Floors

Most of the time you can Jack and then temporary support. I use hydraulic bottle jacks all the time with no problems. If you want to leave a Jack supporting for a long time, use a screw Jack. There are other situations where you could use something like a hylift.

If I have a critical jacking situation, I may use a pair of 50 ton jacks, so one can fail and not have a disaster.

Re: Best Jack For Floors

When I'm jacking floors, I use 20 ton bottles. If they need to hold for a while, lift with the jack then prop it up with posts.

Re: Best Jack For Floors

More often than not, I just cut the temporary support to the height it needs to be, and then put it in place with the 160 ounce framing hammer.


You make something idiot proof and the world invents a better idiot.
