What Our Clients Say

  • I picked up two new agents this week when I did an inspection on a house they had listed.  Both were so impressed with the report format and the way I word things that they declared they were going to use me as their “go to” inspector.  My wording has not changed in the way I report items.  So that means all of the credit goes to the Horizon report format.

    Tim Fuller, Fuller Home Inspections

  • Fantastic reporting system! The best tool in any home inspector’s bag isn’t always in the bag.

    Steve Love, McKenzie-Taylor Associates Ltd

  • After finding Carson Dunlop Horizon software I quickly realized that this was by far the most comprehensive report I could use. The descriptions, limitations, recommendations, and the added feature of implications library has sped up my report writing time by hours. Not to mention the mobile app has become my best friend at the inspection site. It saves me at least 1 1/2 to 2 hours per inspection and my clients are very impressed with the final report. Horizon software is a great time saving product and has given me a definite edge in the inspection field.

    Troy Owen – Owen Home Inspection

  • As president of the NE chapter (ORCIA, Oklahoma Residential Commercial Inspection Association) I meet with many inspectors monthly. I have looked at and tried many different inspection software programs. I have the best looking, easiest to understand report of any of them! I just wanted to drop a quick line and let you know I appreciate your services and quick response when things go awry. Keep up the great work.

    Ken Woolbright, Gold Star Home Inspections, LLC

  • I am proud to say we have increased from three inspectors to ten since starting with Horizon in 2014. We also have three more currently in training. I only say this because Horizon is a significant part of our success. We are very pleased as well with the Horizon Commercial software.

    G Bryan, Houston TX.

  • I am still in “love” with Horizon. What is especially wonderful is how you continue to shape and improve the system without compromising its “roots”. What a great thing for small Companies in the rural areas to obtain the highest quality report writing in our profession, for a fair price. Ariel’s support is great! He is always fast to respond, and never makes us digital laymen feel inferior.
