It's been an incredible experience in hiring Bird Masters LA to take care of pressure washing my driveway,front and back yard restoring the concrete as if it was just layed out. Tree oil stains,dirt build up, bird droppings and tire marks have been completely removed. Soon after I had them humanely remove a bird nest and bird proof my home with bird spikes. They have also cleaned all my windows and screens in/out leaving them spotless. My home is now ready for a family event! thank you for your service in a timely manner and the peace of mind. Highly suggested for their quality work and results.
