⭐⭐⭐⭐⭐

Jonathan Gach is an excellent inspector. Very thorough and explains all concerns very well. He is my continued favorite inspector in my area.

- Debbie Hughes

⭐⭐⭐⭐⭐

Jonathan was a Pro's Pro. He did a more than thorough inspection and written report. We met him at the property and he took lots of time going over everything he saw and explaining with the detail of a college professor. This guy loves his job and it shows in his work. I would use him again without hesitation.

-James Kenney

⭐⭐⭐⭐⭐

This is the 4th Home Inspection I’ve had performed on a property and it was by far the most thorough, technical and balanced out of all of them. No sugarcoating and no alarmism, just facts, data and information on how to deal with actionable items. Will definitely be coming back for assessments when performing renovations and upgrades.

Understanding RESNET Home Energy Ratings: A Comprehensive Guide

RESNET home energy ratings are more than just a number; they represent a comprehensive assessment of a home's energy efficiency. By evaluating factors such as insulation, air leakage, and HVAC system performance, these ratings provide invaluable insights into a home's overall energy performance. With lower HERS Index scores indicating higher efficiency, homeowners can take proactive steps to reduce energy consumption, save on utility bills, and contribute to a more sustainable future.
