Excellent. I would hire again most definitely. Very friendly and professional. Walked around and answered all of my questions before I even had a chance to ask. That is how knowledgeable he was.

Someone put an offer on our house and had Mr. Sieg come to inspect it. He said the house needed extra bracing along the back wall and the foundation needed piering. The buyer cancelled the contract and then came back with an offer of 30,000 less than his original offer, based on this inspection. We then got a second and third opinion from other engineers. By the end, we had three general inspectors and three engineers look at the house. Except for Mr. Sieg, everyone agreed that although the house had settled one inch along the back, this was within the normal range for a 30-year old house and piering was unnecessary at this point. Of course time might prove that Mr. Sieg was right and the other inspectors were all wrong.

Dennis did a thorough and professional inspection of the house and its foundation. I was impressed with his knowledge and professionalism. He was able to point out all the issues and explained everything in terms I could understand. I would hire him again in a heartbeat.

Due to an unexpected schedule cancellation, Dennis was able to do the inspection the day after I called him. I understand this is not typical. He was very thorough, and explained what he was doing, what he was seeing, why certain things were or were not problems, and what could be done about the problems. His written report came via email about a week later, and was very clear. This was a very useful and professional experience.

We needed a licensed PE professional engineer to perform a structural inspection of foundation issues. Dennis was very professional and accommodating with scheduling even though he is very busy. He also did a separate whole home inspection. Both services were very comprehensive. He spent several hours at the house (3-4 hours) for both inspections. Avoid inspectors who tell you they complete the job in one hour. Dennis tells you the facts based on sound engineering data. He will tell you when an observed "issue" is really a problem or if it's one you can go without fixing. His reports may not contain all the pizzaz and pretty pictures that others have but they do contain all the necessary details with recommendations for real problem areas. Highly recommended.

He was prompt and professional. He explained what he was doing and was careful to make sure we understood what he was saying and what we might look for in the future if we thought we were having foundation issues. He wrote up a report on our house in a timely manner and even gave us a couple of tips on what we might do to ensure the future stability of our foundation. I was pleased with the experience and would recommend Dennis to anyone who suspects they might have foundation problems.

After having a drainage company scare us to death about our foundation, recommending many thousands of dollars of piering, etc. we decided to get a FOR REAL structural inspection. Dennis was extremely thorough, inspecting both the interior and exterior of the property and he does recommend a drainage solution and offered two idea about how to resolve the drainage problem. Absolutely no piering is needed of this property. Be super careful of these foundation and drainage companies that are offering a solution looking for a problem. Dennis is your guy if you have any concerns about the state of your home's foundation. He will give you actual facts. The peace of mind is well worth his consultation cost! HIGHLY RECOMMEND!

We contacted Dennis because we had a recurring crack in the ceiling after remodeling work had been done (removing a wall between family room and kitchen). We wanted an assessment of the recurring crack. Dennis came out and did a complete walk-thru of the house (inside and outside) answering all of our questions. Additionally he went up in the attic where the crack was and determined there was a framing issue that was not addressed in the remodeling project. He took the time to explain in detail how we could fix the problem ourselves. We highly recommend Dennis and were very pleased with his service.

The house was settling on the north side. We were concerned about hiring a foundation repair company without knowing what needed to be done. We wanted to know what to expect. He did a thorough job; he walked around the exterior and interior to check. Spartan's analysis matched his. We were happy that we spent the money. It gave us peace of mind.

Dennis arrived when scheduled, and proceeded to do a primary walk-through of both the inside and outside of the house. He then proceed to measure the entire house using a laser level system. My concerns were for the front of the garage where a combination of things caused the front corner to crack. He explained just what the problem was and how many piers would be needed and where they should be located. What really impressed me the most was that he pointed out another structural issue unrelated to the piers with a section of a ceiling that was remodeled about 15 years ago. He explained what was done wrong and how to fix it. All of this with a drawing of the house and elevation measurements was in a report that he e-mailed to me soon afterwards. Great guy- great job- thanks Dennis! NOTE: Overland Park requires an engineer's report on the property before a foundation company does any major work- and that's a good thing. I had a few estimates that were in line with Dennis' findings, but I'm sure there are a lot of unscrupulous companies that would take advantage of an uniformed homeowner; or worse- not have the knowledge to really fix the actual problem. The small pittance you spend on someone like Dennis is WELL WORTH the experience and knowledge he brings to the table in solving a very expensive problem the right way.

Dennis Sieg was recommended to me by a friend, who had used his services on several occasions. My concerns included badly cracked retaining walls, ceiling and wall cracks, drainage issues, and whether my home could accommodate an indoor swim spa. He was very responsive to my concerns, answered every question in depth, and was clearly in command of the subject matter. The information I received was well worth every penny of his $375 fee. Highly recommended.
Description of Work: Mr. Sieg examined both interior and exterior of my entire house, took careful measurements, and cheerfully answered my many many questions. About 3 weeks later, I received his written analysis including illustrations.

Mr. Sieg did an excellent job. He listened to my information and concerns and then performed an excellent, thorough evaluation. He took time to completely evaluate our home's foundation and was more than willing to answer any questions while he worked. He was not just interested in "getting in and out quickly". He took his time and did an outstanding job that gave me the information I needed in ordered to begin the bidding process for the needed repairs. Dennis Seig carries my highest recommendation.

We knew we had some foundation issues and started with getting estimates from two foundation companies before we called Dennis. The estimates were from $20,000 for 11 piers to $5500 for 4 piers. Who was right? I had a couple of friends tell me bite the bullet and find a structural engineer to get a non bias opinion. I looked on Angie's List to find a structural engineer. Dennis reviews were good so we had him out. Dennis was on time. Professional and very informative. He spent around three hours inspecting and giving us his option on repairing foundation damage. Dennis recommended 8 piers and gave us a general idea of what to expect to pay for the repairs. He included a structural drawing of the damage and also a recommended drainage drawing for the exterior. We had two other companies come out for estimates. One was for $8700 and the other was $9700 which was in line with what Dennis had told us repairs would cost. Do your homework before you call anyone! That way you have some idea who's blowing smoke! Dennis helped clear the smoke. Dennis was great would recommend him or use him again.

Dennis came out and spent 1-1/2 hours examining the foundation. He then stepped us through exactly what had happened and why. He then supplied a full written report and explanation to us within a week. This was very helpful in our selection of a foundation company.
