Sagging floors are all too common. But depending on the individual circumstance, that might limit the options for a fix. In this video we look at 3 options to repair a sagging floor without having to use a jack.
The first option to fix a floor sag is to remove flooring in order to sister onto the existing sagging joist new and level joists.
The second option to repair a floor that has sagged is to fill in the gap created by the sagging floor with sheets of different thicknesses of plywood.
The third option to repair a sagging floor is to lay an entirely new sub floor and finished floor over the existing floor. This would involve shimming out the low spot in the floor.
These are just some of the options available to remedy a sagging floor problem that don't require using a floor jack.

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 )! If you are interested, check out the link : DEWALT Line Laser, Self-Leveling, Red, 3-Beam (DW089K) by Dewalt amzn.to/3xNbY3K 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 : kzfaq.info/sun/PLExVGissIl-H-npOe7v64K2y6IIOQvHk6 Just FYI.

i did option 3... and this is my thoughts... none of these options fix the actual problem. those joists and likely the carrying beam are low and need to be raised. Whether its rot somewhere, the sill, or foundation or support sinkage... these problems need to be diagnosed and corrected.

@Housebarons Жыл бұрын

Hey @brandonarcher6118 , Option 1 is a fix (sistering) if the problem is in the joist itself. If the problem is in the wall or foundation - thats another deal. Thx for watching.

Question for a older mansion block top floor flat. There is a light slope in the corridor area and the bathroom and it crackles a bit when walking on it. Once you do the sistering and you have levelled the floor, you put a subfloor of plywood on it right? If I want to make it real solid and add porcelain tiles or engineered wood, can I add a layer of screed or that would cause moisture issues later on? What would be the best option for a solid floor?

@gruber1650 9 ай бұрын

I've got some engineered wood flooring for one of my downstairs rooms, the floors are solid the problem being on one side of the room it drops about 40 mm in the last 600mm, I think shimmying would be the best way, anyone any advice, thanks.

Hello, I presently live in a home that have sagging floors. I have decided to purchase jacks and lift the floors from the basement. My question is are there any prep work required on the 1st and 2nd floor prior to installing the kicks and lifting? Do I need to be concerned with baseboard trim, door trim, or anything. I have received my drawings on where to place the jacks. I understand that my plaster and drywall will also begin to crack in some areas. I just want to get level floors before I purchase my new doors and install new trim.

@Housebarons 11 ай бұрын

Hey Steven, Sounds like you’ve done some good prep. Our practice was to go slow… it took decades to get to that point…so rushing is asking for issues. We’d do a 1/8 inch and let it sit a day or two. Then another 1/8 and rest a day or 2. We still got some plaster cracks… so the slower the better is what we thought. Hope your project goes well. Thx for watching!

@tricatfilms6136 3 ай бұрын

I don't understand this method, after a month or so of raising the old joists, what do you do to prevent them from just re-sagging again? You aren't planning on leaving the jacks and support beams in place are you?

@Housebarons Yessum... got the bathroom left. Kind of took a break and been putting in wood plank flooring starting in the bedroom. Once I get to mid living room I'll go back to leveling. It's fun if it's not a job. Best. You are much better carpenter than I but my floors are secured, level, and don't creek so that's a win

@john_blues Жыл бұрын

Would #3 be good for a bathroom? I wonder about water in those spaces between the shims.

@Housebarons Жыл бұрын

Hey John…, Water is always the enemy of wood. But you flooring should seal your sub floor from minor water like getting out of shower. But let’s say you have a broken pipe of tub overflow. That would cause damage to any subfloor or ceiling below. If you are still concerned, #2 should eliminate any voids (filling them w/ plywood and floor leveler. Thx for watching!

Could I put leveling concrete down once I did option 1 for an upstairs bathroom?

@Housebarons 6 ай бұрын

We chose to avoid that option because unless you are 100% positive there is not a structural issue, the weight of the concrete leveler can do a lot of damage. Just fyi…

ahhh si this house I have an offer on there are no doors except for 2 bedrooms...I said what up with no door on the bedrooms and closet...so they did the subfloor attempt to fix it...but...the floors in 2 rooms still sag. and it looks like the termites have done this and they said but we have gotten rid of the termites....well termite guy said well there is termites in the joist..active...so they tried to fix it that's why there are no doors....am I right...I think I just gonna walk away ..

Yeah - w/o being able to see into each joist cavity - you could be buying floors ready to collapse- I would walk before buying termite damage. Too risky w/ so much unknown. Hope that helps !

Not only did they have damage. They also had active termites in the joist and water was called them to their crawlspace. I’ve been $1800.

No. That is so stupid . You go under the floor. Under the house. You install nrw joist and support beams , jack up the low spots until level and nail or screw them in place. A bad or sunken pier or a rotten joist is most likely the problem.

I have a purchase to offer ( in due diligence now) on a 100-year-old house I noticed they took the doors off 90 percent of the house... I think it was because the termites had done the damage the inspector said he saw...and the termite guy said termites are still the joints... but the doors were removed because the still sunken floors were not fixed... I think I should just walk away another 1600 down the drain
