Houston Overhead Door

I have lived in Woodwind Lakes subdivision since day 1. So naturally I called Houston Overhead Doors when a spring broke on my Garage Door.
It was late afternoon, and as luck would have it, they had a truck coming back in to their shop, and they were able to send them to me right away. I am across the street from them!
Great, so how much will it be??? The owner replies, well… the technician has to see what you have, and will give you a price
So the Technician backs up my drive way, he looks at the broken spring (1), and says it will be 185.00 to replace 1 spring, or 315.00 to do both. Springs cost $ 42.00! So the labor is $ 143.00. Each! Now I can either replace the spring myself (which I have done a few years ago), or let them do it right now, and not risk losing a tooth if the wrench slips. So I say go ahead. From the time they backed into the driveway, until they took the check from my hand was 16 minutes. $ 20.00 a minute to replace the springs!
I am ok with that. A company needs to turn a profit to be able to be there next time I need them. The tech hands me the Invoice, and I get inside to write the check, and it has $ 320.00 instead of $ 315.00 like I was quoted. Before I go in to get the check I tell the guys, get yourself a cold drink while I get the check.
When I return I see the older guy has finished one beer, and had a couple more in his hand! Must have been real thirsty. I guess he does not understand what «A» means.
I point out the overcharge, and the response is «oh I forget what I say».
Seems to me that if you install springs for a living there is a standard charge for that service, but I feel like the price I paid was based on income not cost Plus material and Labor.
I called the owner to thank him for being so fast (33 mins from first call to finished).
But, I am disappointed that I was charged more than the QUOTE! And his reply was, yeah I saw that, and I’m real sorry that happened. So I am anticipating his resolution, and He say’s, next time your are out, COME BY and get your $ 5.00 dollar’s.
I am sure most would agree, he should have brought the five dollars to me, but apparently it would be too much trouble to take 5 minutes to correct their oversight.
If a company does not understand the importance of keeping your word, then what else will they take the liberty of overlooking? I know, I know… it was just $ 5.00, but that is not the point. Integrity is the number one reason I hire someone. I can’t trust them to do me right, therefore I can never hire or recommend them again. By the way, my garage door works perfectly!!!
