Too many people view others in the same industry as "competition." While that might be true to a certain extent, it's also alienating those that can help you. The Houston Metropolitan Area is huge, not just in population but in land-area. Go to other major cities (New York, Chicago, Atlanta) and you'll see that Houston is very spread-out. Viewing everyone as competition in Houston is not the way I see things. I'd rather network than compete. I don't want to--actually, I WON'T--drive 60 miles for a $250 job. I'd rather pass the job off to another PW company that I know works that area and does a good job. Some guys would rather just tell the customer, "Sorry, I don't service that area." That's a poor way to do business if it can be helped.
Actually, having a FEW, similar priced competitors is actually GOOD for business.
The PROBLEM comes when supply exceeds demand, and price chopping occurs.
You beat my price, I beat yours, Billy Bob beats both of us.
No one wins except the customer.
Actually, the customer LOSES, because to get down to a low price, important things like a ground man are often left out.
I would like to see this TSP discussion get back on track ?
Sodium Hypochlorite, or bleach, is not a surfactant.
That is why it is a good idea to add a little TSP, or some kind of bleach compatabile surfactant to the mix.
It makes for a nicer job.
Can you clean roofs with just Sh and water, yes.
Same way you can slap some brake pads on w/o turning rotors/drums.
Sometimes, you can get away with it.
Is it the RIGHT way to do it ?
Depends on what quality work you want to produce.
I have actually done roofs with, and w/o TSP in the same subdivision, and came back later to compare them.
The roofs done with TSP added ALWAYS looked a little better.
Here are some before and afters of a tile and shingle roofs done with Apple Sauce.
It has TSP in it.
