Costs vary greatly. The most basic driveway gate system in the Seattle/Tacoma area will run about $10K. Most of our residential gates run around $15-25K. If you're looking for pricing on commercial or industrial gate systems please call us at 1.800.278.5418
The answer to this depends on your driveway and on what you're trying to accomplish. If security is your main concern then a slide gate is preferred. If curb appeal is your main concern then you want a double swing gate.
If you're in Eastern Washington solar is an excellent option. In Western Washington, not so much. It can work, but in the middle of winter, you will surely be swapping out batteries or will need to hook up temporary power and a trickle charger.
You will need an electrical permit for the gate automation. This is usually purchased from the state, but some cities issue their own. You may need a building permit, depending on the jurisdiction that your property is in.
