Randy, the owner, came out to give the estimate and signed a contract to replace, not just repair, my leaky skylight. He ensured me that his people would do a great job. He assessed the problem that the skylight needed replacing from the base of the roof in its entirety. When his workers arrived, Jason, the guy in charge, said that the roof was quite brittle so they recommended just replacing the skylight dome itself and then seeing if this fixed them problem. He left instructions to call if it didn't fix the leak and that they would come back and replace it completely if that was the case. Of course, when it continued to leak, I contacted both Randy and Jason, both of which were either rude or dismissive of me and never came back to fix the leak, after taking my money. Jason was especially rude and threatening - I have his text messages to prove it. Please don't use Mountainland, anyone else would be better. I never leave reviews but in this case I wanted to get the message out.
