Home Inspection

When purchasing a home, having a detailed report about the reliability of your home is extremely important. Madrona Building Solutions checks all of the major systems of a home to ensure safety, durability and proper operation.


Americans, on average, spend 90% of our time indoors, where the levels of pollutants are often 2-5 times higher than outdoors. To improve indoor air quality, we provide testing for common pollutants and provide recommendations for ventilation and filtration systems.

We (in a multi-family setting, 30+ households) hired Jeff Aslan to come do an “electrification consultation”’ for our large common building, which he accomplished on one day’s visit, after which he produced a very thorough online report that went far beyond our explications, quite happily. He was a pleasure to engage with and really knew his stuff. We are much better off for this material; which was very worth his reasonable fee.

Jeff was extremely professional, detail oriented, and thorough. We had him complete a Healthy Home Assessment and he produced an incredibly detailed report that we have been using to gradually chip away at home improvements, especially to improve air quality in the house. He also conducted mold and water quality testing which has allowed us to address issues unique to our home in a more targeted and efficient way. Highly recommended.

Jeff was a joy to work with! He is responsive, and really went the extra mile on my project. He voluntarily scheduled a review with me and broke all the information down over Zoom and in writing, making sure I understood everything. I cannot recommend him highly enough and plan to use him again to do an energy audit on my main house.

Jeff made our lives so much easier by providing us with detailed and thorough information for our HVAC consultation. We had no idea where to begin or how to make the right decisions for such an expensive addition to our business. Jeff is knowledgeable, communicative, professional, and presented his findings in a way that were informative and easy to understand. We will definitely use his services again when we have another project.

We couldn't have asked for a better home inspection experience. Jeff has great attention to detail, content knowledge, and customer service. The report he developed is comprehensive and user-friendly. Jeff's willingness to describe technical details in layman's terms was also incredibly valuable. We would certainly work with Jeff again, and will recommend his services to all of our friends and family.

Jeff visited my house (under renovation) to evaluate its building envelope. A complex mix of siding, vapor barriers, air barriers and insulation are all vital components but confusing. Jeff provided insight and clarity for a stressful subject and recommendations for all of the above. And stayed with the project following the inspection to answer question and further guidance. A good written report. Timely, accurate and well thought out recommendations. I felt good having Jeff on my team to ensure my house achieves energy efficiency and is done right.
