Residential, Commercial and Expert Witness inspections.

History

Established in 1973.

In the early 1970’s, private inspections of homes and commercial properties were a relatively unknown commodity in the Detroit area. Thanks to the vision of Lon Grossman, a licensed builder with almost 30 years of experience in building and real estate, the concept of professional real estate inspections took hold. Today, inspections are the norm in most real estate transactions.

In 1973, Mr. Grossman founded Technihouse Inspections, Inc. on the premise that the interests of buyers and REALTORS® could be served best with a clear understanding of the exact condition of a building on the market.

The company’s mission is to provide prospective buyers with necessary information about a structure so they can make a decision with the confidence and peace of mind that it’s the right one. Technihouse inspectors objectively, thoroughly and accurately inspect all major building components — the electrical, plumbing and heating system, the roof, insulation, windows, overall structural integrit

It was through this experience that Lon learned much from others and taught himself the building, repairing, and renovating trades. Years later, Lon decided to share his expertise and start his own business, Technihouse Inspections, Inc., in order to help people make informed decisions when purchasing a home.

His personal affiliations include serving as an Executive Board Member for Leader Dogs for the Blind. Lon is also active with Habitat for Humanity.

Professionally, he holds memberships in ‘ASHI’ (American Society of Home Inspectors) and NAHI (National Association of Home Inspectors).

Working with Lon has been great!
We recently used Lon on two home inspections. The first was definitely an eye-​opening experience, and we were extremely grateful for Lon’s honest opinion and thorough examination of the home. The second, and the one we are purchasing, was just as honest & thorough, and a great experience.
As first-​time home buyers, Lon was incredibly helpful in not just explaining what he was looking for but providing an education for how to complete different maintenance and repair activities. Even if you’ve owned a home before, Lon is great at providing his insights on how to make different changes /​updates, etc yourself.
Also — if you’re looking to laugh, Lon was a great person to spend 2+ hours with — never a dull moment with him :)
Thanks Lon!

My seller’s realtor once called Lon «the deal breaker». Your home is probably the most expensive long term investment you will ever make (besides children), and he’s worth it.
Lon has inspected three houses for me– the first one I didn’t purchase, not because Lon said it was a bad house, but because he was honest about its condition and the amount of money to bring it back to life. Lead paint, asbestos, knob and tube wiring, and a dangerous fireplace were among the issues. He told me I’d spend at least $ 100K to renovate it properly and I wasn’t ready to make that kind of investment. The next house I ended up purchasing, and Lon helped me make an informed decision. Loved the house, sold it a few years later.
Fast forward a few years, and I“m ready to buy another home. I wasn’t present for this inspection, but Lon walked my boyfriend and his father through everything and helped us feel confident in the purchase we are making. Lon is thorough, detail oriented, and honest. I can’t say enough good things about him and I am so grateful for his services!

There is absolutely no better inspector. His credentials notwithstanding, Lon conducted an amazingly thorough inspection– pointing out flaws to the builder’s project manager – who was literally speechless.
Lon explained what could be a problem and helped us save much in time and money. He is trustworthy and extremely professional. No inspector is better.

Lon is a top-​notch house inspector. I expected someone good considering who I got the number from (construction company owner in business for over 20 years) but I was blown away by how detailed and thorough he was, it was evident he didn’t want to make certain we understood what he was talking about to cover himself, he sincerely wanted to educate us about this home. He declined providing a service we thought we might need — despite the money he would make and how easy it would be for him to perform, assuring us it was unnecessary. When the sellers of the home tried to cover up what seemed like a big problem, Lon was happy to come back to us and discuss the situation, cautioning us against buying a home when the seller refused to acknowledge a large potential structural issue. Would not hesitate to call Lon again and refer him widely. Like the construction company owner told me, «this guy is a realtor’s worst nightmare!»

I didn’t realize at first that I was dealing with the man whose articles I clipped and kept as reference for many years. You know that old saying «You get what you pay for» Well you get you moneys worth here.
Even my realtor picked up some info!

Lon saved me from stepping on a 92k land mine. He is extremely thorough, explains the entire inspection process and even gives out worksheets and a book on home repair and maintenance. Highly recommend and well worth the extra money to potentially save you from a costly mistake.

Do not buy a house without this man! seriously! he is expensive but very worth it! he knows everything, like this furnance was in a class action lawsuit 7 years ago, and that wall is wet, but the city didn’t see it. very professional, even suggested we walk away, from one house, and told us the next one was fine. i trust his judgement!

I don’t even know where to start. .. Lon is absolutely fantastic. I worked with him on two back to back home purchases and both times were wonderful experiences. His technical expertise is second only to his attention to detail and charming personality.
The best review really is that I would never use another home inspector. The guy is the absolute best. Thanks Lon.

We have used Lon for two home inspections on older homes that required very careful inspections. He was early for his appointments and is prepared for anything. He does a very thorough inspection and explains everything carefully. You can ask him any question and get a complete answer. Highly recommend him.

I have used Technihouse in the past for house inspections with great success. Today I set up an appointment to have my current basement reviewed. I have had leaks over the years and would like to finish the basement. I have a wide range of quotes from a variety of waterproofers. Lon was able to review the basement and confirm what should be done and which quote made sense. In addition, Lon pointed out a number of additional updates that I should make for the safety of my home. This will be a large investment in the quality of my home and I feel confident going forward. I highly recommend Technihouse.

Lon was great, this is my first home purchase and he went through and explained every single thing that was wrong, explained how to use every single thing in the house and what to expect from each thing. And after he was done he gave a yearly checklist of what I should do to keep everything going smoothly and catch any issues early on. On top of that after he walked out he came back in and gave a do-​it-​yourself book. The guy was great and I feel like I could do just about anything in my house.

This was our very first home inspection. Lon did a great job. He was very thorough and explained everything. He deserves more stars because he saved us 135k. We will definitely use him again on our next home inspection.

Lon is a great guy and extremely knowledgeable and very professional. This was the best money I ever spent. The cost was insignificant compared to the huge amount of money I would have spent repairing all the issues he uncovered. He definitely opened my eyes.

Lon is incredible. He’ll find everything that’s wrong with a house, and help you make an informed decision on your purchase or remodels that will improve the integrity of your home. We’ve used him twice and he’s definitely my go-​to inspector.
He’s also incredibly funny! It helps to have an inspector with a personality when you’re hanging out with him for 3 hours at a time.

We recently used Lon for an inspection and were very pleased with services. He is knowledgable, thorough, trustworthy and resourceful. This home is the most expensive purchase we’ll make and we wanted someone who would nit-​pick and gives us a real overview of the state of the home. I appreciated the report at the end of the inspection. He followed up personally after the inspection and was open to every question.
You get what you pay for so, don’t hesitate to hire Lon.

Lon Grossman is the consummate inspector with 30+ year of experience. He’s a stickler and he’ll tell you exactly what you need to fix what’s wrong. He’s prompt (he arrived early!), thorough and I recommend you walk along with him and take notes, though he gives you a detailed report and pictures. There are many competitors but Technihouse was one of the first in the Detroit metro area and has done thousands of inspections. There isn’t anything Lon hasn’t seen. I would recommend Technihouse highly. Do not buy a home without a inspection. It’s too important of a purchase to take the risk.

We recently used Lon on the inspection of a home we’re currently in the process of purchasing. Lon was extremely thorough and willing to offer insights into his findings. My wife is well advanced in home improvements and not once did I feel as if Lon was talking down to us, he wanted to make certain we were all aware of what we were potentially purchasing.
In the world of home inspections, I’ve learned you get what you pay for. Working with Lon, you pay a premium, but it’s well worth it. I’d recommend him to anybody seeking a true assessment of the condition of the home they’re considering purchasing.

Lon was recommended to my husband by someone and after we spoke with Lon on the phone, we decided to use him. As a potential home buyer, you want to feel like someone has your best interest in mind and right away Lon makes you feel at ease. He’s thorough, talks you through everything (good and bad) on a house and when you get to the equipment section of a basement, he labels EVERYTHING so you know what’s the hot water shut off vs. the humidifier shut off. He’ll even tell you whether a cost estimate you received is WAY off base or appropriately priced. Lon himself is premium priced and he will tell you up front that he is not the cheapest guy in town — but you get what you pay for in this case. Once we got to the end of our 3.5 hour inspection my husband and I felt he was worth *every* penny. You’ll receive an info packet along with your detailed inspection report to help you tackle some of the manageable DIY repairs. He’ll also provide several images for your records. Anyone who has something bad to say about Lon is likely trying to pull a fast one on a potential home buyer. A thorough — albeit more expensive — home inspection is worth the peace of mind.

I had Lon inspect a home I’m purchasing this morning. He was recommended highly by my attorney, who said that «He’s the only person I’d ever want to work with. If I was buying a house, he’s who I’d have inspect mine.»
Lon explained in great detail things that a first time homebuyer should know. He meticulously poked and prodded everything in the house, and gave explanations and advice (along with a rough idea of estimated costs, recommended timelines, and repercussions if I didn’t) for fixing things. He asked many times if I had any questions about anything or if I needed more explanation. I learned a ton about furnaces, attics, and plumbing!
Will Lon nit-​pick? Sure. However, he told me when things were important or when they were just nit-​picking. He offered expert, objective advice — the kind of advice you get from 35 years in the business. He also safety tagged all the equipment in the basement (what things should be shut off in an emergency, what to do if the hot water heater leaks, etc.).
Lon is extremely good at what he does. I have to laugh at Karen’s review — «Lon is very good at breaking deals.» I told Lon this, who said «I don’t break deals… houses break deals.» To continue with Karen’s review, «If you are a first time buyer, or insecure about buying real estate»… and this is where I’ll diverge from her opinion… you couldn’t have a better professional in your corner.
TLDR: Real estate agents hate him… with good reason.
