Subfloor is being removed from my home, unfortunately it had to be done. Urine stained and water warped MDF boards had to go. It's like 70% done then we have to address a couple spots where the original subfloor is water damaged and rotted. Just the smell of that subfloor as it was pulled up reassured me that we made the correct call.

@jasonthorpe3470 Год назад

Make SURE you know where your water lines go before doing this. Laminating the subfloor in this way was how I found out the fire suppression lines in my condo were mounted directly to the underside of the existing subfloor. That made for an exciting night - especially because no one in my condo knew how to turn off the fire supression system, so water poured into my condo for 3 hours before we found the right person. After spending a solid week repairing water damage in the floor below (just my garage, thankfully, and not a neighbor) I marked out the fire suppression system on the old subfloor, and made darn sure to stay 12" away from the lines when putting in the new screws

I stacked subfloor in my bathroom to get a better transition between the original 3/4 oak outside the bathroom to the vinyl plank flooring inside.

I did this exact thing in my studio space above my detached 2-car garage. There was only 1/2" subfloor over 24"-on-center joists (!!!). Needless to say, it was a bit springy. The extra 5/8" made it feel rock solid, and it's much quieter to walk on. Will be installing a vinyl plank floor over it soon, with help from Jeff's videos 👍

You can check a carpenter square by using a known straight like on a sheet of plywood and marking a line, then flip the square over and mark another line as close as you can to the first one, if it's a little off you can take a center punch and hit either the inside or outside corner depending on which way it's off. ;-)

I thought i would have to do the same in the house we just bought. Two first floor rooms had floors that creaked with each footstep. I was very close to overlaying new sheet wood, but decided instead to put roof felt over the construction insulation under the existing floating chipboard floor, and then another layer between the chip and the insulation that had been used to raise the floor level. After relaying the laminate floor it is silent. But handling that sheet flooring is harder work than you make it look!

@Watermelon_Shuga 10 месяцев назад

Question: I was waiting for you to explain how you were going to address the vapor and insulation issue causing condensation between the subfloor and flooring but you never did. Did you put a vapor barrier and insulation under the mobile home or fix holes in the existing vapor barrier and insulation? I have the same problem but worse. The plastic belly wrap was missing, insulation hanging, and my floors were bleeding on the Summer between the vinyl tiles because of condensation coming through the plywood subfloor and getting trapped under the vinyl tiles.

Future cable contractor likely won't use the old cable, and won't take time to remove and use existing holes, likely just drill into living room/office and run new cable to whatever rooms they want (or just to router for wifi nowadays). Up to you to seal all the holes nowadays, not like decades ago when they used grommets.

@johnmilner6419 6 месяцев назад

Starting at 8:30, those lousy cable wires belong behind sheetrock. I would use a drill and jig saw to cut out a piece of the original subfloor (if it's not accessible from a crawlspace), and wire the lines though the walls by using a sheetrock knife or roto-tool to cut a line even one foot above the floor, along the wall, to where they want it coming out. It would delay the project by a day, but the alternative, of having to live with that crap forever, sticking out of the ground, always makes it worth it.🙂

Plywood is crappy these days and often pretty bowed. I was taught to run a row of fasteners straight down the middle each direction forming a cross. Next, working from the center outwards, nail each quadrant. This forces the bow down and outward. You didn't, but I can't count the times I've seen people place the sheets, then nail all the seams first. 🫣 I've installed flooring since the mid seventies, learning from my grandfather. It's refreshing to watch your videos explaining the why's and how's to those that watch. Some new to the trades, but I'll bet many are diyers.

@rennethjarrett4580 10 месяцев назад

I knew when I moved into this old house the remodel before i bought it was maybe a cover up in some places. The first obvious on was the back part of the house, see a crack come across the ceiling as I was putting more things in that room up stairs. So with in a month or so of moving in I decided to check this out as much as i could without opening any thing up. What I realized was that the second floor on that part had only three cross beams besides the outer frame. Leaving two spans of 4 feet, and one at about 3 and the other around 2.5 feet. So I built a support frame from about 1/2 of the room on the first floor to add support for that center beam, where that crack in the ceiling showed up. Well now about 12 year later I have dips in my first floor at those 4 foot spans, and the one side is concerning. I don't want to take up the whole floor, for the huge reason is the cost and that fact there is a large kitchen counter and sink on the one side and it covers those spans very well, so I don't want to move it all out. the floor feel like they might have even used Masonite and not plywood or the plywood is rotting or just weak from the long span and a kitchen table one it for many years. This part of the house is basically built on the ground and I have no way under it all. There is a small opening on the one larger better 4 foot area, at my outside basement entrance and I put my cell phone on a stick and slid it under and as best I can tell that area is not rotted. So I can guess it was just to much weight at 4 foot span. So my plan is to open part of it up to look under and then add 3 to 5 cross supports to the three ones that are there and maybe, get some added support to the ground. Then put most of the flooring back if it is not rotted and then put either a layer of 3/4 PVC sheet on top or 3/4 plywood.. The other fun part is the back door is level with the current floor and opens in, however it will need to be fixed as well since its' bottom was partly bad and I did a makeshift protection and mouse stopper back then, so having to raise that door bottom was going to have to be done anyhow. So I wonder if I go with the PVC sheet should I run it outside to cover the whole base of the walkway, and then put a regular door seal on top of that or just stop at the door with the floor?

Perfect timing! My mobile home flooring is swollen from various leaks and laminate floor was layed on top. Joints are popping. This is a 1975 single wide in Arizona 55+ park. I bought it right, but must be realistic. Surrounded by newer homes. I was just about to tear out bathroom subfloor. Plumbing is all replaced and roof is fixed, so cautiously optomistic. A little concerned about covering the soggy stuff, but think it should dry out with this 115 heat. Your thoughts?

@HomeRenoVisionDIY Год назад

the softness does not affect the strength of compression. your dry environment will keep it from going to mold. remember it is soft not wet. Cheers!

@AltruisticWarrior 3 месяца назад

As a fellow carpenter desert rat that works in Phoenix but lives in Las Vegas, you should be good. Can always take things a notch further and get yourself a gallon of oil based zissner primer that blocks mold and mildew. Paint your subfloor with it, especially in bathrooms! Your future self will thank you should you ever have any leaks. It's a very small and cheap insurance policy to CYA. I did this in my house that I remodeled recently as well. I'm a commercial carpenter by trade and while many things apply, it's still a vastly different world in other regards. Haha I will say that hanging board on perfectly straight metal studs with self tapppers is way better than residential... minus code that requires 2.5x more screws.

@owKeylimepie Год назад

Do you keep that 5/8" gap at the tie-in to the hallway? I'm assuming it's within the flooring tolerances but wasn't sure if that was the case or if it'll be addressed when you take a look at the bathroom and determine what you need to do. Thanks!

Glad I'm not the only one that couldn't seem to find any actual flooring screws! Watched a TON of your videos and I could never find flooring specific screws like you had mentioned before. Also, curious if there was a reason you chose plywood over OSB here, or maybe I missed that somewhere.

@RJFerret Год назад

OSB's cheaper (well, used to be) because it's just glued together fibers. It's not glued together dust like what he's covering/complaining about, just a step up. Plywood is actual wood layers, laminated together. It has some structure to it. Sure it costs a bit more but will last multiple times longer. Now pressure treated plywood, costs even more, but will outlast other parts. I bet since he's sticking to a budget, he went for plywood. OSB's cool for wall sheathing, but I'd not pick it for something that gets heavy weight sitting on it (furniture), traffic (weight and flex of people walking), etc.

@martyvanord984 9 месяцев назад

From a building science perspective, the code mandated crawl space ventilation attempts to defy reality. Hot warm moisture saturated air enters the cool crawl space and condenses. If a vent fan is installed to pull outside air in to the crawl space, the bottom of the floor will collect rain drop[s and rain down on the bare ground. The informed recommendation is often to install extremely heavy plastic sheeting with the sheets over lapped and vapor sealed to each other and the perimeter. To prevent rodent problems they recommend, 4 inch deep pea gravel both above and below the plastic sheeting. Supposedly it is impossible for them to dig because it rolls into its self. Then seal the crawl space and most important install an economical to operate whole house dehumidifier that pumps the moisture into a drain exiting the house. An informative experiment is to fill a glass or metal cup with ice and then add water. If you take it outside and set it on a hard surface, a puddle of water will collect around it. Often it can be shocking to see how much water the air holds. Matt Risinger is a big proponent of whole house dehumidifiers.

I think the convo was more, "We're selling in a few years, we just need safe and make it look okay now, hopefully potential buyers won't notice."

So if your raising the floor essentially do the doors still clear after installing flooring over the double subfloor

@4vinylsound Год назад

In the beginning of the video where the floor at the by the wall wasn't level and you could put your finger under the ruler how did you raise up that end of the wall I just saw you put a piece of plywood down about 8 inches off the wall but you didn't show how you leveled it off when it dips down on the sub floor

@triciasanders2455 Год назад

That's what I was waiting to see.

@HomeRenoVisionDIY Год назад

use a floor patch compound before installing the new flooring to level all problem areas!

@4vinylsound Год назад

@@HomeRenoVisionDIY please show how to in a video. Thanks. ;)

My grout in my tiled bathroom floor is cracking due to flexing subfloor. Sub floor has concrete panel between tile and subfloor. What’s the best way to fix this? Thank you !

@thescavwithnothingtolose1224 Год назад

Could you do this on a second story bedroom floor? My daughter's room has a flexing spot that squeaks.

@meadoman2000 6 месяцев назад

Jeff I have to ask as I have been watching your videos and listening to you, wouldn't it be very expensive on adding the plywood over the top of what already there, especially like in my case in the bathroom the toilet sinks when you sit on it, which means I need to tear it all up and probably have to put in 2x4 or 2x6

@yelenapants 5 месяцев назад

What type of plywood do you use? Is it moisture resistant or do you need that? I found some CDX plywood that I’m thinking of adding to my existing subfloor but don’t know if I should do anything to protect the wood.

How would you fix subfloor flexing in a tiled bathroom.?The grout is cracking and there is concrete panel between the tile and subfloor . Thank you!

@Randygr86 Год назад

Can you do this on hardwood? Also, can you level the new subfloor at the same time?

@HomeRenoVisionDIY Год назад

best to remove anything with cleats or nails if possible.

@WoodyWoodworker 6 месяцев назад

maybe a really weird question but does it help to lay down a second subfloor to prevent noise movement to the lower level? Of course I would also use a Mass Loaded Vinyl layer on top of the second layer subfloor.

@hodgepodgejourneys 11 месяцев назад

I purchased a manufactured home and I had to pull all the flooring up. I though the subfloor was soft, but found that there was way too much padding under the vinyl floor which was making it feel like I was walking on a mattress. The 3/4in particleboard is solid with no soft spots. Whoever put the flooring in decided to use self leveler on the particleboard and it is not level. I was told the best fix is to put 3/8in plywood over the particleboard and just staple it with no regard for where the joists are and where the “self leveler” is. It looks like you would recommend that I use screws and screw it to the joist?

@hundredeyes5148 8 месяцев назад

how much did this strengthen your floor? does it feel really strong now?

@bjre.wa.8681 Год назад

would the cement type floor leveler be an option as well?

@MustPassTruck Год назад

You need a stable floor before you use the leveler first usually.

@christianmaupin6551 3 месяца назад

what if you have particle board 1/2" over a subfloor that is squeaky? Romove the partial board first or go over with another layer of solid plywood 1/2" sheets with screws? FYI - the old particle board has 1000s of nails in it as well.

@tst.v2926 4 месяца назад

@homerenovisiondiy this may be dumb but in theory I get using 4 x 8. Would 2 feet by 4 feet work (half size pieces)? I plan to glue too. I’m doing alone and 2 x 4 feet pieces would be easier.

@falloutfan2502 Год назад

I couldn't help but chuckle - the finishing in my basement was paneling over paneling, because the paneling underneath was wet and rotten. It was so bad that I could poke my finger through it, but they "fixed" it by just putting another layer over it. Really expensive and difficult to repair, but buyer beware I suppose. :(

Once you found the bathroom and half the hallway was done I would have just pulled up the bedroom and finished pulling the rest of the hallway and you could have had no transitions. Would look much nicer.

any flat oil will work. odorless zinnser is nice to work with.

@nickreiter6412 Год назад

I would address it with the customer, let them make that choice. Some people just don't have the extra funds and may have HAD to fix a soft spot so soft they would fall thru if not fixed. Flooring is ridiculously expensive, then add the labor. I have installed floors for 27 years in Indiana

In this case I am the customer. I don't want to patch it knowing the whole house is a ticking time bomb.

Hey Jeff, would you reccomend just going over old subflooring if the origional subflooring is only nailed down? (Not screwed or glued)

@asawoszc Год назад

If the existing subfloor is already exposed then no harm in throwing in some screws anyway IMO. Maybe not as many needed if you're putting another sheet on top. Just my 2c.

@HomeRenoVisionDIY Год назад

I really don't find a lot of value in the glue if you are screwing so save what you have and screw it in.

@skyline5354 Год назад

I got a bit of flex in my floors. Cannot access joists from basement as ceilings are dry walled. Can adding another 4x8 sheet of plywood on top stiffen it up? Or should I pull up the original subfloor and add bracing in between joists? Thx

@kimmorgan4963 10 месяцев назад

I am new to the DIY scene and have a single wide trailer that I will be attempting to renovate/repair. With that being said, is it still ok to add new plywood over the existing, if there's a possibility that the joists may be rotted?

@HomeRenoVisionDIY 10 месяцев назад

rotted joists must be replaced. as long as you repair the vapor barrier underneath you should be fine to add a new layer of subflooring. expect another 20 to 30 years out of it.
