New House Wrap Over Poorly Installed Existing Wrap
Hey all,
General Contractor house wrapped with Everbilt on the osb sheathing for a smaller 3 sided addtion. The catch is they don’t do a fantastic job. While 9 ft roll, there is are a bit of wrinkles.
I have 5ft Tyvek, cap nails, and gumption. I am also open to eating the cost of the Tyvek and getting something else, even as simple of an upgrade as Tyvek Commerical in the same 5′ width.
I am very much aware that if I go Tyvek over Overbilt, I need to select which is the water/air barrier.
What should I do? Keep and move on? Take off Everbilt to add the Tyvek? Add Tyvek over the Everbilt?
The other details are mortair rainscreen and then Hardie Plank siding. Nothing else.
Thank you!

I feel this should elicit passionate responses, causes marble statues to move from their pedestals...
I love Everbilt housewrap! It's the loudest, most emphatic way, as a contractor, to ensure I'll never, ever hire you.
Edit: I realize I forgot to answer the actual question. You could certainly go over it, but like you said, makes some detailing a bit more tricky. On every job I've seen it installed, it seems to disintegrate if you look at it wrong. How hard could it be to remove?
Not hard to remove at all. Luckily they used a lot of staples instead of cap nails, so I think a really good yank should take it down. I imagine a pain around nails because it's plastic...
It adds a day for this dad to redo...and winter is fast approaching...admittedly I wish I had wider Tyvek HW than 5ft...but at least I know I can pull that tight by myself...Just want to make sure it make sense to rip it off or do tyvek over it
Ryan_SLC,
Definitely take off the Everbilt before replacing it with the Tyvek. It is only only 11 perms. The Tyvek is 56.
Thank you kindly for the response. Thank you and will accept this a right. It will come off and Tyvek will go by itself. Thank you!
How long before the siding gets installed?
Generally, the wind will find a week points and the weeks the house wrap is exposed insuring the house wrap is neither and air or water barrier.

Now that I have my answer not to double layer Everbilt and Tyvek, that's a good point. I am aware that dirt and wind knock Tyvek effectiveness...but I hadn't actually brought that back into wait until the very last second when inspection comes and Hardie goes immediately up.
Thank you!
Do you all mind this next question?
I have Tyvek House Wrap (5' width). Can't return it.
For 310 dollars, I can get the same width and length Tyvek Commercial.
Is the difference worth buying? There is sunk cost, but is there a performance gain worth some sunk cost?
Thank you,
Ryan
Is there a reason you're using 5'? The wider the roll, the fewer seams, the better it works. Less taping too.
Oh great question.
From what I can google search/buy as a non contractor, it's $310 for 5' width Tyvek Commercial or 9' Tyvek HouseWrap for the same price. Since I already have House Wrap 5', I'm not sure I'm willing to spend 300 on the same just wider.
I wish I could find Tyvek Commercial wider for reasonable, but my googling isn't good or it just doesn't exist, for me...
Well installed Tyvek is fine. If you install it right before siding, I suspect it will be in fine shape and the commercial product will not provide any real world benefit.
So I found rather questionable place to buy Commercial in 10' X 125' lengths for too low to be true.
But I put the card number in and will roll the dice. At that cost, it's a no brainier as putting it up will be so much faster/easier...maybe not easier with just me. No windy days I hope!
Rolled the dice.
Ryan_SLC,
Given the choice I use Tyvek Commercial, simply because it is a lot easier to install, as it doesn't tear as easily and holds staples better. But there is nothing wrong with regular Tyvek, especially in the shorter rolls where it's less likely to be damaged during installation.
One advantage of Tyvek Commercial is that it does a better job of rejecting vapor drive from the exterior.
You all have been extremely helpful. It's greatly appreciated
Small three sided addition ... consider removing the Everbuilt and going back on with a self adhered WRB. Blueskin etc. Much better water and air barrier. IIRC the perm rating is about 33?
I have started digging into Blueskin and I am finding a lot of posts that the product is extremely unforgiving and extremely flimsy. Homedepot reviews all are negative and it's not available.
I was about to pull the buy, but backed out.
Flimsy is not a word I would use to describe BlueSkin VP100, far from it. Any of the SA WRBs will take more care to apply than staple up Tyvek. BS is everywhere in my area builds (zone 5 MA), including high end shore front builds on Cape Cod. Call the area rep, he was super helpful. My own experience is that BS hit the best value point on the Tyvek to Siga scale. Good luck.
