That's why most homeowners opt to pay about $150 to
$200 (out here in the Silicon Valley anyway) to have it done.

Or more ...

By way of partial proof, here's a 'special' $200 deal for my area:
http://www.thegaragedoorstoresanjose...placement.html
"Your garage door is the largest moving object in your house and can
be dangerous? Make sure it isn't. When looking for expert garage
door repair service in San Jose, Santa Clara, Los Gatos, Campbell,
Saratoga, Milpitas, and Sunnyvale; call us today for our $199 spring
special! 408-281-7111"

I arbitrarily called about a dozen local (408 area code) garage door
repair outfits yesterday to obtain that $150 to $200 price range.

Incidentally, I MUST say, I had the most interested phone call yesterday
to "Tiffany" at 408-335-0145 when I was shopping for local repair costs
for my research summary to you guys at alt home repair.

That outfit literally called me back twice to get my business!

First, they called back to lower the price of the service call from
$50 (just for the estimate) to $30 and to offer to refund that lowered
price service call if I got their $150 to $250 service - and then -
when I still declined, Tiffany called back today saying the new manager
just authorized her to drop the service call fee altogether.

At that point, I 'could' have taken then up on their offer (just to
get a more specific estimate for you guys) ... but ... I didn't really
want to jerk them around so I politely declined (but thanked them
nonetheless).

I mention this because many people reading this will want to have
someone do the work for them - so it's good to know you still 'can'
get a free estimate in the Silicon Valley (but only if you play their
game).
