I'm trying to hang a curtain rod over a sliding glass door, but keep hitting something that I can't drill through.

The house is built of cement blocks, but there is drywall on the walls. I had another house that was the same type, but never had a problem with hanging curtain rods. The anchors can't get in far enough to hold the rod in with whatever is stopping it. Any suggestions would be greatly appreciated.

    I'd pick up some tapcons http://www.concretescrews.com/ and drill pilots...these screws come in a two sizes and different lengths.

    Thank you so much, I'll give them a try.
  • Tapcons will work. But using a hammer drill is going to be important. You are hitting the block wall behind the drywall. Sometimes over the door they use a precast cement header and in some other cases they use a steel angle iron. If your hitting the steel then tapcons will not work. You will need a metal drill bit that is sized properly for plastic anchors drill out, put anchor in and then screw to fasten rod bracket.

    You're likely drilling through the sheetrock and hitting the concrete blocks for which you'll need a different type of bit....perhaps a diamond bit. Check at your local hardware or big box home improvement store for the appropriate bit.

  • Sounds like you need a concrete bit for your drill and the proper anchors.

    Get a masonry bit and use that to drill with.

  • It appears that the problem you're having with curtain rods hanging in a home with drywall-covered cement block walls might be the result of ordinary anchors not going deep enough into the wall. Use different anchoring techniques, such as toggle bolts or masonry anchors made for cement block walls, to address this. These solutions ensure that your curtain rods are mounted firmly because they are stronger and more stable. Consulting with knowledgeable staff members at your local hardware shop may also yield helpful guidance unique to your needs. You may successfully hang your curtain rods and overcome this issue with several anchoring options and professional advice.
