Loretta Wolf2024-12-13Trustindex verifies that the original source of the review is Google. I can’t say enough how great Grand Exteriors was! They worked with my insurance and explained the whole process. When the crew came out they were very careful and did a great job cleaning up after the installation. Everyone was so friendly and easy to work with. I wish all repairs went this smoothly! Our roof looks great and I rest easy knowing with their repairs and upgrades that my roof is better than ever. Thank you all so much! Brian Risko2024-09-29Trustindex verifies that the original source of the review is Google. Rob and his construction crew did a fantastic job. I was very pleased with the quality of work. They were very accommodating and the odd items I needed them to address was not a problem. I would highly recommend Grand Exteriors to anyone looking for a new roof! Julia Dieter2024-09-11Trustindex verifies that the original source of the review is Google. Every part of the process with residing our house was smooth, timely, and efficient. Kyle and Rob are both extremely knowledgeable and professional. Upon having them come out for an estimate it was immediately apparent that they had the confidence to carry out the job. I would hands down hire them to do another project when the time arises. From start to finish they kept us up to date on everything and their team was amazing as well. We are so happy with the result! Thank you! I have attached before and after pictures below We opted to have NewTech wood installed Out of all the estimates that we had (which were about 4) Grand exteriors was the only company that was familiar with the product we wanted to install. Fran Dwyer2024-08-01Trustindex verifies that the original source of the review is Google. Owners Rob and Kyle along with their multiple teams not only delivered on the work schedules they committed to but exceeded our expectations on the work being completed. Their installation teams experience and knowledge showed right at the start of the each of our three projects. We had two roofs replaced, complete siding replacements, and twenty new window replaced. The crew provided daily cleanups, provided a end of day update, and provided the next day expectation of work to be completed. Owners Rob and Kyle were very hands on with management of the project and provided clear and decisive expectation as well. I highly recommend Grand Exteriors for your next Roof, Siding, Window, or Gutter project. Fran Dwyer Jennifer Hurd2024-08-01Trustindex verifies that the original source of the review is Google. Robert and his team were very professional. We had an urgent and unique situation about our roof and they went out of their way to help us-replacing our roof as quickly as possible. Upfront transparent pricing. They were organized and smooth about installation. Documented and explained the process to me as they went along. I highly recommend this company.
