Fencing contractor?

[Aki]

Hello, we are having pig problems....major damage to our yard...we had some trapped but they haven’t stopped...our neighbor built a fence and no problems for them...so we have a shared fence on one side...we need about 600 feet more...any contractor recommendations for a basic fence that will keep pigs out and looks ok...lava rock in most places....

We went through the same thing. All the bids were in the thousands of dollars. We ended up with an o'o bar where possible and cinder blocks filled with concrete to anchor posts over blue rock. Not fun, but you only have to do it once. I also just saw a listing under farm and garden on Craig's list for a guy advertising he was a fence builder.

I always thought fence contractors were crazy over priced. Until...I put in my own 1 acre hogwire fence. I said I would never do that for somebody else for less than $7,500.

Just my 2 cents. I would look for someone more of a handyman type than the fencing contractors. They charge by the foot and are always thousands higher than an individual.

It's not easier to do it yourself, but you'll end up with all the tools and knowledge necessary to repair/modify the fence after you're done.

Tip for the "surface-mount" technique: use a pressure washer to clean the pahoehoe and massage the wet concrete onto it, you'll get a really good bond that way. When setting posts, put some kind of anchor on the bottom; for pipe, drill two holes and stick 1-2' of #9 bottom wire through, cover with concrete.

Metal posts, too; wood posts only seem cheaper.

If you have solid rock at the surface, that's the best situation. Rent a hammer drill and a 1 1/2" bit, drill a hole about 12" deep, hammer in T-post. Repeat.

[My 2 cents]

And use RockTite to cement post in and to keep the hole from filling up with water.

Thanks for all the suggestions and recommendations....very helpful...

drill a hole about 12" deep, hammer in T-post

...after removing the flange with a small sledgehammer, and typically with "bigger" posts every 50-100' depending on terrain.

Two posts in an H-brace on either side of a gate and/or every so often (again, terrain) because you need something to pull against when stretching the fence.

Note that when renting the pneumatic drill/jackhammer, Puna Rentals will only give you 50' of hose, so access is a potential issue. Consider clearing the line with a small machine.

Drill a 5/8 hole in the rock one foot, grout in a 2 ft section of grounding rod (it won't rust) wire a length of rebar , 1/2 in will do to the piece sticking out. Make a form 4 in sq the height you need and pour it solid with sand and chip concrete. Vibrate it to insure it is solid. Don't cheap on the cement. If you want you could put an X of rebar on the rock and pour a small pad before filling the form.
There are concrete fence posts at Glover by the lawn that have been there at least 50 years that I know of and still show no signs of wear. You need a long bit, good concrete drill.

Maybe your "infestation" is too entrenched for this idea, but it worked for me: spread chemical lawn fertilizer (not organic) all over the property. Pigs are smart; they don't like chemicals. I did this and it was near-instant gratification. 2 nights later they were gone and haven't been back in the 8 months since. Worth a try.
