 Trustindex verifies that the original source of the review is Google. Great job! Nick and Christian were super professional and thorough. Careful and very detail-oriented. They were up on the roof and in the Attic negotiating a catwalk that was very tricky. They fixed a bathroom exhaust fan hose that was dumping into the Attic and also were able to reach a very small section where condensation was dripping down some conduit from the roof vent. They were super personable and efficient. 100% confidence in their work. Highly recommend.
