Caring for such an "antique" or even a newer version of your old brick-walkway is a rewarding task. The classic look of that brick can be restored with the tip of my pressure washer wand ;-)
The one thing to watch out for is the "thirst" of the porous brick: It has to be saturated with clean water before any pressure washing can take place. That is to say, before any cleaning detergent should be applied. Why this is so important you can read here ..
Are the bricks of your walls, drive- or walkways longing for the 'Good old Days', where they would glow from afar in their beautiful, deep dark-red color, always welcoming everyone? (Oh yes, I am feeling poetic now!)
Give me a call and I come to their rescue! (813) 991-7243
