I had a few estimates confirmed from different companies with different approaches to cleaning overgrown moss from the roof (chemical spread with manual brushing, pressure-washing and soft washing with or without chloride solution) ranging between $1500-2,500) Picked CleaneRLook because our roof (concrete tiles) could and needed to take a light pressure washing, they were most available at the time, responsive and informative and the price wasn't as intimidating. 2 pleasant young men arrived on time and worked really hard on our house for 2 full days. It's been 3 weeks in April, no issues so far. I'm very pleased with the new look. The only reason I muted 1 star is because they left all the bags with the debris for us to get rid of. They apologized in reply to my complaint and hopefully learned from the mistake. Otherwise the roof, gutters, siding and patio are all clean...what a difference! Will call them again.
