We are now retired and no longer providing engineering services.
David was a little late, and the inspection took longer than I expected-2 hours-but the quality was exceptional-and he told me my foundation was fine! He recommended that I just reinstall my storm doors in new frames and that I really didn't need any foundation repair. Hearing that was well worth the cost. I would absolutely recommend him to anyone else.

I should have used Mr. Isbon for the main inspection and saved myself a lot of money! He was prompt (early even), extremely knowledgable, friendly, and totally professional. He even helped us resolve a later issue with our lender regarding the foundation on our new house. Diana is a quick responder and also very friendly. I would absolutely recommend Isbon Engineering to anyone, and if I ever need another home inspection, there's no other company I would use!
Description of Work: Mr. Isbon performed a foundation inspection that was recommended by our general home inspector.

It went fine. David was prompt and he stayed for a decent amount of time and explained some things. We were mainly just disappointed in the general report for the inspection (as mentioned above) and the pier and beam foundation charge that was added even though that work wasn't performed.
Description of Work: We had a house inspection performed. We chose Isbon because it seemed like a 2 for the price of one type thing since he is a structural engineer and we thought there were problems with the foundation of the house. So this way the foundation and the general inspection could be done. The inspection was fine, but compared to the company we used for a different house inspection (LC Inspection) it was not great at all. The bigger frustration for us was that David said he couldn't check the foundation at all because the house was too close to the ground for him to get underneath to check. It's a pier and beam foundation, and Isbon charges $50 extra for pier and beam, to go under the house. Well, he couldn't get underneath or check it at all, but then he still charged us the extra $50!! We found this to be unfair since that was an extra cost for a service that was not performed. (Also, we have had other people get under the house to do other work, but he did not go under even though he charged us) We thought that the inspection information could have been more detailed and had more pictures included (because the other inspector we used did that). He may be great for other work regarding structural engineering, but for the inspection part we would definitely recommend using someone else.

David was very pleasant and knowledgeable. He took measurements inside and out. He examined cracks inside the house and very promptly sent a report out. While at our home, he was so thorough and precise. He made sure we understood everything. The reports were sent as a pdf file and answered all our questions.

I called the office of Isbon Engineering and just as others have said, Diana was helpful and pleasant when scheduling an appointment. She set appropriate expectations about the process. David Isbon came on the scheduled day right on time, proceeded to check out my small 1151 s.f., single story, house...did all of the measurements, and at the end of the process, he said that I do not need to have my foundation jacked up with piers. He did the inspection on Friday, and on Monday I received his formal e-mailed report.
Description of Work: I wanted an independent and professional engineer's opinion about whether I needed to get piers under my foundation due to cracks appearing inside my house after last summer's drought.

He was great. He measured everything, looked at the old reports from previous contractors and even examined the foundation blue prints. He explained things in a way that made me feel informed without feeling stupid. He even pointed out ways that I could save money on the work I need to have done on the house. He gave me piece of mind about the job to be done.
Description of Work: Took detailed measurements in EVERY room, prepared report and explained foundation issues in laymen's terms.

Very good experience. I contacted David after noticing some fairly dramatic cracks in my drywall after only having been in this house for 6 months. I was afraid that something major was going to have to be done to the foundation in fairly short order, but I wanted to get a professional to look at it. David Isbon arrived at my house when he said that he would, began taking measurements inside the house and also looking outside at any structural issues. He crawled under the crawl space to see how my pier and beam foundation was holding up. Afterwards we talked about the problems, he showed me a detailed look at the sloping issues in the house and was able to pinpoint the source of the problems. He suggested waiting 6 months to determine the rate of settling before getting a quote for new piers to be put in. He thought that it could also be seasonal settling and may correct itself in the Spring. This put my mind at ease and I'll probably get David to come back out in May or June of next year. David sent me a pdf file of the info that he took of my house along with a CAD drawing showing how the house slopes. I was very pleased with the expertise and felt that I certainly got more than what I paid for considering that I was about to just call a foundation repair contractor to start installing piers.

David Isbon's office made the appointment and was flexible about the times available. Very nice office person. David showed up at the house a few minutes early. He rang the bell at the appointed time, took a few minutes to make sure I understood what he would do then he set out to do it. He walked the perimeter of the house and took some measurements, then came inside and looked around upstairs and down. He then took a lot of readings and made a sketch of the house, marking the readings as he went. David told me that the cracking was a result of normal settling and since it was only an inch difference anywhere, there was no compelling reason to make any changes. He said he'd give me the name of some masons to fix the brick and advised me to get estimates and let them know that I was looking at several people. His report included several masons he recommended.
Description of Work: Foundation inspection was requested since I have a slab foundation and a couple of cracks in the exterior brick and hairline fractures inside around some doorways.

David Isbon was very professional and friendly. He emailed me the full report in 4 days with some recommendations. I had several questions regarding different observations, David sat with me and answered all the questions and gave me his cell number in case I had further questions. I am pretty happy with his service.

We were primarily concerned about the foundation due to some cracks we'd seen in the interior walls. Diana was very helpful and was able to schedule our inspection in under a week. David's foundation inspection was very thorough and he provided an elevation survey drawing to show where the house has settled, by how much, and he explained clearly why we see cracks where we do. His thoroughness, experience and documentation convinced us that the settling is well within acceptable limits and we're not concerned about the foundation, and are purchasing the house. David's home inspection was just as thorough. After the inspection he walked me through the house and reviewed the major items. He followed up via email with the formal 20 page document explaining all his findings (both problems and non-problems, so we know he looked at all of them) and highlighting the items that were hazards and needed particular attention. One of the items David brought to our attention was that parts of the 2 Heating/AC units were old and looked like they could cause us trouble, so he recommended an inspection. Following his advice, we had a Heating/AC contractor (from Angie's List) out to inspect the units and found they needed nearly $6000 worth of repairs. We were able to reduce the purchase price of the house to pay for the repairs. Overall, I couldn't be more pleased with the inspection provided by Isbon Engineering. David is knowledgeable, easy to talk to, helpful, patient and above all, thorough... Exactly what you need in a home and foundation inspector. We got far more than our money's worth!
Description of Work: Provided a home inspection and foundation inspection on a home we're buying.

Overall excellent. Report was detailed, and Mr. Isbon communicated everything to me in a thorough manner.
Description of Work: Mr. Isbon came out to my home to perform a structural evaluation of the foundation. He produced a report detailing the work that would need to be done to bring the foundation up to par. After I had the work done, Mr. Isbon came out again to inspect the work done by the foundation repair company.

David arrived on time and was very professional. After performing the evaluation outside the house and inside he explained that our problem was caused by tree roots and that tree root barriers were recommended. Foundation companies said we were needing piers. Within a few days we had received our official report from David. I would recommend calling Isbon Eng. first before calling a foundation company.

I first decided to hire Mr. Ibson based on the other reviews on Angie's List, and I'm glad I did. I was able to make an appointment within a week of when I first called. When the day came, he showed up towards the end of the window that was originally giving to me. He was very personable, and we spent more time talking than I was expecting. In that time, I learned more about his background and home construction in general. As an engineer myself in a different field, I was comforted by our discussions since it gave me time to assess his competence. Nothing that I saw gave me any doubt about his ability to give me a fair and accurate account of my foundation. As it turns out, my 55 year old house does have a solid foundation. I have been concerned because of noticeable slopes on my floor and cracks in my walls. He assuaged my fears and let me know that it was only superficial damage, that the foundation itself was sound. I have doubts that any free inspection from a foundation repair company would ever have been as honest. All in all, I am very pleased with the work that was performed, and for me, the peace of mind was well worth the price.
Description of Work: Mr. Ibson completed a "Level B" inspection of the home. This included a visual inspection around the house to check for a foundation issues that could be found there. He also performed a topographical gradient map of the home to determine height differences around the house. He completed his inspection by crawling into the sub-floor to check the location and integrity of the piers and beams. Once he completed his inspection, he verbally informed me of his findings. After a few days, I received his complete written report by email.

David was very prompt and very professional. He is a kind and soft spoken individual who comes when he says. He came all the way from Arlington to Dallas to inspect the work to be done. He drew up the plans that we needed and was able to discuss it in detail and any other questions we had. He later came on two other occasions for other work that we are planning to do. He is not always able to return our calls, but he does usually answer his own phone when you call him. I think that he is just SO BUSY that he can't do it all. He finally told us that he is just too busy to draw up plans for our next project even though he was nice enough to come to the house twice to look at the job in detail. However, he did recommend me to someone else that he trusts. My husband and I are very happy with what he's done so far, and we very much like talking with him. He's down-to-earth and not a big "salesman" like some other people out there. He doesn't try to "pull the wool over your eyes," and his office lady is very nice, too. We hope to be able to rely on him again if we need him.
Description of Work: We asked David to draw up some foundation plans for a detached 2-car garage that would be very sturdy.

I thought that the inspector did a thorough job. He spent quite a bit of time outside and at least twenty five minutes under the house. He gave me the names of several companies that I could use. He gave me a written report that day and was kind enough to e-mail it to me again, so I could send that to a prospective repair company.

From scheduling to receiving the report, I was extremely satisfied with David's inspection. As a new home buyer, I shared the report with some friends and the general consensus was that he did a very thorough job and that nothing was left out. He did find some areas of concern, namely my HVAC and I was able to take the information to my sellers and negotiate further to accommodate the cost of a new system. He also was able to recommend a termite inspection service that was very reasonable and easy to work with as well. His cost was a bit more than others I spoke with, but none were structural engineers. As I was buying an older home, it was important to me to have an inspector with that qualification in case foundation concerns arose during the inspection. David didn't mind having me there for the last hour of his inspection and answered all of my questions. He also took the time to prioritize his findings in order of importance. For example, the HVAC issues also had safety issues and he did say that he would not recommend buying the house without addressing those. Other issues, such as a old motor in the bathroom vent he suggested that I take care of on my own. It was very helpful when it came down to the last negotiations with my sellers. He was very clean, did not leave a mess or track in mud, etc. The sellers did not mention any upset after his visit either. I have recommended him to friends.
Description of Work: David provided the home inspection for the home I purchased in fall 2007. It was my first time to buy a home and I was very inexperienced and nervous about the process. The home was built in 1937 and although updated, I was concerned about foundation, insulation, etc. He was extremely thorough and is also a structural engineer, and was able to explain in detail what he was looking for and why. He examined everything from the foundation to the handles on my kitchen cabinets. The report was sent to me almost the next day via email. Scheduling was very easy as well. My original message was returned promptly and I was able to schedule the inspection around my work day.
