    Picked an Owens Corning Contractor and he uses synthetic Tri-Built for underlayment.It appears the synthetic is equivalent to 15#. I'm in a northern climate and have had ice dams. The estimate budget was such that I'm wondering whether there is any benefit to me asking for a "better"...

    Hey all, I'm down to the joists in my master bathroom, ready to install fresh 3/4" Plywood Subfloor. When I ask friends their opinion on my flooring layers needed for tiling, I usually get one of the following (conflicting) answers: 1. Just put 1/2" Cement Board directly over your subfloor...

    I'm installing laminate flooring in a 5x7 walk-in closet that is connected to the bathroom. The floor in the closet and bathroom is flat, but slope towards the same direction. The slope in the closet is 1", as well as in the bathroom (the tub is level). I've looked at ways to level the closet...

    We removed ceramic tile, cement board and linoleum to expose subfloor due to water leak. We need to add plywood to exisiting subfloor. My question is does it have to be "plywood underlayment" or can it be 1/4" or 1/2" OSB? Does this get screwed and glued (with liquid nails) as well?

    Hi I have just removed tiles and concrete hardibacker from a bathroom. As I removed it, I saw that the layer of 1950s sheet flooring with felt backing approx 1/8" thick beneath is was already removed in some random shaped areas. The areas that remain are easily pried up and if it was safe, I...

    Hey crew! I removed the floor of my upstairs bathroom down to diagonal wooden planks. (is this called the sub-floor?) Now, I bought 1/2" Hardiebacker and Hardiebacker screws, but internet searches show most people using Thinset to adhere hardiebacker to the floor. 2 Questions: 1. Most photos...

    Hi there, I am new to roofing, so assume I know nothing! I found lots of dry rot in my crawl space, caused by water coming in from above. So I am cleaning it all out and trying to find the source of water ingress. I have just put a few more screws in along the drip edge which was lifting due...

    Hi everybody! I'm getting ready to install new luxury vinyl plank in my kitchen. The existing floor is peel-and-stick vinyl tile stuck directly to linoleum below. I can pretty easily pull up the vinyl tile, but it leaves a lot of adhesive behind on the linoleum. Now the new system is a snap...

    I'm up here in MN, based on intense weather and weather tightness, I'm debating on using high temp ice & water on whole roof (28 sq roof, 1-story home), versus just ice & water along outside wall and valleys. The cost difference is only about $500 more. Here is the product I'm looking at...

    I am replacing my existing toilet flange and the linoleum flooring in my bathroom. Unfortunately, the original hole in the 3/4 inch subfloor around the sewer pipe is too large. As a result, my new flange would only be screwed into, first the tile and then the hardie backer I laid over the...

    I am doing some remodel on a ranch house that was built in 1985. I'll be putting down 3/4" unfinished hardwood (likely red oak). The underlayment was particle board and not in good shape, so I'm replacing it. I found that my subfloor is only 1/2" plywood. Joists are 16" OC. Trying to decide...
