Mark from The Install Company is amazing to work with. Very knowledgeable and very detail oriented. This is the type of installers Panda Windows and Doors likes to be partnered with. Thanks for the amazing install on the 12’ tall bifold doors!Posted on Google![]()

Mark at The Install Company is a lifesaver! I'm a real estate agent and needed someone fast when a client's sliding door system wouldn't lock. Mark jumped on it immediately, was incredibly responsive, and got it handled without missing a beat. After calling what felt like every door company in the metro area, he was the only company who even knew about this particular door system (Panoramic Doors). If you need someone who knows what they're doing and actually shows up, Mark is your guy. Highly recommend!Posted on Google![]()

We had a pesky Nano door that was giving us all kinds of issues. After calling numerous groups, Mark was the one who not only was happily willing to come out, but after a short duration, solved our issue. True professional, and we would definitely reach out again if anything else comes up in the future. Thank you!Posted on Google![]()

Mark is a true professional. We appreciated his balanced perspective and advice as we navigated a difficult real estate transaction. We had a scary inspection report that Mark helped us dissect. He put forth a very compelling quote to get our body of work done and was urgent and responsive in his communications with us during a stressful time. You won’t regret working with TIC!Posted on Google![]()

Mark was incredibly helpful and accommodating when the technology on a Pergolux sliding glass door failed after a power outage. He rearranged his schedule and came out the very next day, which was truly lifesaving since I had an open house scheduled. What impressed me most was that he researched the issue the night before based on the information I shared, so he arrived prepared and ready to solve the problem, knowing I’d have a house full of people. His communication, professionalism, flexibility, and overall consideration exceeded all expectations. I’m so grateful we connected and would absolutely recommend him to anyone needing this kind of help. I also learned he does contracting work, and I’m looking forward to working with him again in the future. Thank you so much, Mark - you’re the best!Posted on Google![]()

We were very impressed and extremely satisfied with the deck from the Install Company. The communication was top notch with Mark and Bronn.

The Install Company, (Mark Politto) came to give us a price for all new windows. From the 3 companies we talked to, his cost for Anderson windows was right in the middle. The windows are beautiful and really opened up the spectacular views we have. There was a bit of lag in the schedule and some complexity with our project could have been managed better but we are loving the end result. I tried to provide some before and after pics. There was a lot of wood around the old windows, which had also lost most uv protection and seals. We are excited to see how our new Andersons perform this winter. And especially excited to see our Continental Divide views a LOT better.
