Cost of drilling 9/16 inch, 3 inch deep holes in concrete wall.?
These holes are needed to attach ledger board, for a deck. The 2x8 inch treated ledger board needs 1/2 inch bolts, every 16 inches. How much could I expect a professional to charge to drill this type of hole??
I have drilled the first 20, but it is very labor intensive and I thought a pro might have a special diamond drill or bigger hammer drill to make it go easier. A new drill bit every 4 holes is a bit expensive.
These 1/2 bolts are installed with epoxy mix.
I do hit rebar in the concrete from time to time. The other option would be to make the deck free-floating, with a double beam. But that means more concrete tubes for supports. Help!!

Not a lot, that type of job can be done quickly and easily. So expect to pay the builders minimum fee, which is usually about one or two hours of labor (30-50per hour depending on where you live). Don't worry about the cost of drill bits, most pros use higher quality bits (the ones I use cost about $40 but they will drill hundreds of holes.)

I undertook a similar project. You need a Hammer Drill and a 9/16" hammer drill bit. I bought a hammer drill on sale from harbor freight for $45.00. An appropriate bit was another $7.00 from Lowe's. After trying to drill the holes with a standard drill and masonry bit (like 10 to 15 minutes per hole), I was completely and totally amazed at how fast the hammer drill was at making holes (took like 20 seconds). It was totally worth the money, even if I never use that drill again.
FYI: I found in a subsequent project that drill will drill a 3/16 hole in concrete block in less than 2 seconds. Same hole took 90 seconds with a standard drill.

Not sure if a pro would even spare the time for a "small job" of drill a few holes, but i'm sure you could ask around maybe the hourly rate would be say $15 - 30 /hr
rent a SDS rotary hammer drill, and a masonary bit maybe? why didn't you attach the ledger board into the rim joist of the house? it would have been easier.

go to home depot and purchase a bosch bulldog rotohammer and the bit to drill your redhead anchors and drill the holes put tape on the shaft of the bit for depth . if you hit rebar move over or down , When you drill if the dust quits boiling out then its obvious your hitting rebar. Also some of the materials that the concrete plants used was from stone quarrys and you will run into a hard spot ever so often.If you go pro, better have alot of money its very costly.

Drill them yourself, even if you have to buy tools. It's easy, and you'll have the tools when finished. Mark the hole locations, and drill tiny holes first. Use the pilot holes as starters to drill about 3/8 dia, then use those as pilots for the big holes. You can put a rubber band around the bit to mark the depth, so you know when you're deep enough. I'd probably use lag bolts with lead anchors for this work. Put fender washers on the lag bolts before installing.

Drill lots of little holes until you can get your drill bit to the 15" depth, then make good with sand and cement, after you have fixed whatever it is you are trying to fix. Best i can think of without telling you to hire an drill and bit of the correct size and diameter. Hope that helps. Good Luck.

not too much . depends how many you need.
a PRO will charge you a minimum fee for a service call. a hammer drill will drill a hole as described in a couple min. figure a new bit will be needed after about 4 holes they cost about 5 bucks.
in short if you call a handyman expect about 50.00 for the first hour or so plus bits and about 40.00 per addl hour

Stop all the drilling and shoot it fast. Shots are not expensive and you may be able to rent the gun. They are really quick and relatively inexpensive. If your concerned with holding power shoot it at 10" o.c.

It depends, but at a Rent place you could rentt one, maybe get someone a customer or employee that has experence that can and will doit cheaper than a company, or give you info on someone reasonable
