Hello my name's Joshua, I have been working on cars for the better part of my life. I started working on cars when I was a child, with my father and grandfather, and am now a father of three myself. With the training from my father, and his, I have continued to teach myself and have become quite the auto mechanic. I started my own mobile auto repair company this year after deciding that I wanted to create something that my children could take over someday. Everyone I have done auto repairs for has had a great experience and was more than satisfied with my work. My knowledge and efficiency have shown through in every job I have completed. I take great pride in the work I do and believe in honesty. When speaking to customers, I will take the time to explain the why's and how's of their car problems, give them all their choices for the resolution of the problem and provide guidance on prioritization, based on both mechanical and financial need. I welcome the customer to watch my work and often offer to teach them how to do it, in an effort to help them with future repairs. I believe in doing the job right the first time and guarantee my work for 60 days to make sure I do every job to that standard. My labor price is one of the lowest in the Portland area and I take great pride in being fair and helping people out. I do all repairs for my clients at the most convenient location for them, I will come to you wherever your car needs me. I do not mark-up the prices of the parts which offers the customer another financial advantage over in house automotive shops. I receive a business discount at select auto parts stores, which I pass directly onto the customer, as yet another way I intend to offer the best work at the best price in the Portland area. I offer a free quick estimate by phone, so give me a call and let my family help yours in a time of automotive need. Please and thank you.

Elemental Energy is a highly experienced solar PV design and installation firm for residential and commercial clients throughout Oregon and Southern Washington. Locally owned and operated right here in Portland, we pride ourselves on providing creative solutions to your home or business energy needs, and aim to make the process of going solar simple and efficient.

"We had our house reroofed in January 2025. I got several bids, all came in about the same cost. We ended up selecting Elemental based on their knowledge of our existing system (Enphase) and their great description of what was going to happen. They coordinated with our roofing company to make the whole process seamless. The technicians that did the work were very professional and did a great job explaining what they were doing. The original mounting hardware had leaked a bit requiring our roofer to replace about 10 sheets of sheathing. The technician explained how the new mounting system would protect against leaks. They also applied some additional caulk to ensure a good seal. I would highly recommend Elemental for anyone that needs a removal/reinstall for reroofing."

Energy efficiency auditing services FAQs

An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
