S4 Inspections uses the latest technology to provide thorough inspection efficiently. When walking on the roof is restricted or prohibited, drones enable us to perform a roof inspection while remaining safely on the ground. This lets us access all areas of both the roof and the upper exterior sections of a property.

I recently worked with Anthony for a home inspection on a property for my client and I was very impressed with the service.
He was thorough, professional, and took the time to clearly explain his findings. The detailed report with photos + videos was extremely helpful and gave us a solid picture of the home’s condition.
I especially appreciated how honest and straightforward he was about any deficiencies—no sugarcoating, just practical information that helped us make informed decisions.
He also followed up with a separate video call invitation to go through the report thoroughly and answer any/all questions.
I would highly recommend Anthony to anyone buying or selling a home in the area.
I’ll definitely be using him again for future inspections!

Fantastic service! We were beyond grateful that Anthony (owner) was able to come out last minute, despite his busy schedule. He was professional, thorough, and answered all our questions. The report was detailed, easy to read, and ready within a day of his visit. He even gave us a follow-up call to ensure we didn't miss anything. We highly recommend S4!

Working with Anthony was an absolute pleasure. His unparalleled expertise and attention to detail shone through as he meticulously inspected every aspect of the property, leaving no stone unturned.

What truly set him apart was their ability to communicate complex findings in a clear and understandable manner, making the inspection process accessible and informative. Anthony's professionalism and courtesy was exemplary, arriving promptly and maintaining open communication throughout.

He went above and beyond to ensure my questions and more importantly my client's questions were answered and concerns addressed, demonstrating a genuine commitment to customer satisfaction. I wholeheartedly recommend Anthony Tanagretta from S4 Inspections for anyone seeking a top-tier home inspection experience.

Attention to every single detail you didn’t even know you needed to know. As someone whose spouse is also in the industry we were thrilled with our inspection. Everything was simple to understand and it created a usable list of what needed to be prioritized in what urgency. Cannot recommend enough!
