Old House Renovation 3 - Subfloors - fix dip in floor and replace rotted wood

In our old house renovation project, we show how we have tackled a variety of floor and subfloor issues. Because of the the age and deterioration of the old house in places, renovation efforts had to be concentrated on making sure we could start with floors as level as possible.
We dealt with a number of issues - rotten wood, unlevel floors, use floor leveler, adding 3/4 inch subfloor, using shims to level a floor, water damage to wood, sistering joists, all of which are connected in one way or another to fixing flooring issues or flooring problems.
We supported the unlevel floor joists in the basement with new beams and screw jacks to make sure all was solid. Then we went on to get the main floors level with a combination of a new subfloor with floor leveler in one small area.
The second floor over the kitchen area had new floor joists sistered into place from underneath because weakness caused by notching and water damage.
In the bedrooms on the second flood, we decided that floor leveling with shims and new subfloor was the best route to take in order to keep additional weight on the old joists to a minimum.
What remains is to rebuild a sunken addition and add new joists and walls to a badly weakened structure.
Only when the floors are in good shape can we progress too the next steps of renovation of our 120 year old house.

We can not stress enough the VALUE of having a laser level when doing this kind of work (or even checking the condition of the floors )!

It works well but this is NOT the most affordable version. We actually have 3 different brands and they ALL work great. If you are looking for more affordable options, check out the video description or our other floor leveling videos in the following playlist :

Solid video. I’m working on a 100 year old now. Very similar issues with notches, saggy floors, dips etc. it’s been fun correcting em. Get to see first hand what shoddy carpentry, plumbing will do to a house over the years. Not so fun trying to track info to fix them. We’re a consumer society and the knowledge of how to fix and mend.

And I thought I had it bad..

I’ve been saying how I could have built an entirely new house in the couple years I’ve been working on the one I’m living in. So glad it wasn’t this bad. Good luck man

Would love to see a full video on y’all lifting the wall to get it level. I’m doing the same to a house I just purchased however the siding is brick. I really don’t want to pull all the brick down.

Wow. Kind of incredible the house is still standing given how much wood was gone in places. Are the screw jacks a permanent fixture, or will those parts be supported in another way long-term?

I'm needing this done in my home. What person with what credentials should I be looking for ? I'm lost!

On the second floor you mentioned shimming before the new subfloor went in. I would like to know how that is done. I did the exact same thing and had a hell of a time with it with mixed results...

Why do people buy these type of houses that needs massive amounts of remodeling it is just throwing away money in my opinion...
