  • "Guarantee has handled the repairs on my house after multiple heavy hail storms. They do a great job and make the process very easy. I find my self bragging about how easy it was getting our place fixed up when my neighbors are complaining about what they are dealing with."

  • "A recent hailstorm caused some serious damage to our home. Dealing with insurance and repairs can be quite frustrating. Thanks to Dan Odenthal, the repair process went smoothly from start to finish. Our roof was reshingled in one day. The workmanship was of fine quality. The roofing crew was polite and did an excellent job cleaning up. I was impressed with the repainting of our home. Freddy and his crew were thorough and paid attention to detail. The paint job is neat and tidy. My wife and I couldn't be happier! I highly recommend Guarantee Construction Group. Dan Odenthal and his staff will strive to provide you with friendly and quality work."
