I would not go with anybody other than Blue Door. He walked me through the whole house, pointed out everything he found, and answered every question.
★★★★★
Jonathan fit me in on short notice. The inspection was thorough and went far beyond what I expected. He saved me thousands I would have paid later.

Integrity and good character, at a reasonable price. He did the inspection the same day, listened to our concerns, and methodically went through the wiring, furnace, plumbing, and more.
