I called Alber & they immediately sent out Joe Girouard who has been servicing my air unit over 10 years. he arrived within an hour. I needed batteries in my wall unit. I had no AA batteries. Joe took the batteries out of his flashlight & put them in my unit until I order them. Joe went above & beyond in his job. Using his own personal batteries to service my unit. Wow. What a great service man. He should be commended for going above & beyond in his device. What a kind may. Thank you for employing such great service men

Do NOT recommend. I…read moremessaged several roofing businesses via yelp for an estimate. This company asked for my address in order to provide an estimate. I gave my address and never heard back, so I moved on to another company. Today, 10 days after they never responded after I gave my address, while in the middle of a meeting, I hear a bang outside and my dog freaks out. I go outside to find two men with a ladder against the front of my house and climbing to the roof! I had no idea they were coming and they were fully on their way to climbing up my house without my permission! The problem wasn't even on the roof, so I have no idea what they would have done once they got up there. When I messaged the company to say I didn't appreciate them coming unannounced and unscheduled, I was told it was my fault for not specifying that I expected a call before they showed up! Wild. Do NOT send this company your address--even for an estimate--or else they may randomly show up to your house and climb up on your roof unannounced and they will go up there whether you are home or not. Then if it bothers you they will blame YOU!

I'm fairly stingy with my ratings so take this Good rating as sign of a quality roofing company who…read morestands by their work. Even a Good roofing company is hard to find in Philadelphia. I have found Marcy the owner is to be straightforward and honest, and though she can be a bit brusque at times, as she is in the Philadelphia roofing business I can understand. Their pricing is reasonable for quality of work. No roofer is cheap and if you apparently find one, don't trust them. We have a complicated roofscape (skylights, large AC unit mounts and penetrations, and major crickets required to clear drainage obstructions) and some leaking problems that predate our ownership. Castelli, and particularly their foreman Jimmy, have been generous in attending to drainage problems that may or may not have been a result of their work. I appreciate their work and the efforts made to help us negotiate our finicky roof.
