He is truly the old fashion worker your grandparents tell you about from back in the day.
Shane is the most professional contractor I have ever interacted with for a job. From the first time calling him to the time he left my property he was 100% sincere with everything he did. We requested to put on a new roof on a shed and fix a rotted floor. He recommended putting some extra TLC into the shed including siding and some other work. We didn't think it was possible due to the age of the shed. When he hit some roadblocks with extra issues dealing with the project, he kept his cool. He even worked in a non-shaded area, with a heat index over 110 degrees with no breaks. His employee had the same mentality and I could see his dedication as well. He was younger in age, but Shane educated him along the way. I could tell he was helping to shape the next generation of contractors. Shane was trying to put the love of the work back into the job rather than just completing the work. He told us the new problems we didn't know about and quickly addressed them. He didn't get upset by me asking questions and even gave detailed answers to my questions. If you want a person who shows the ability and love of his work, hire this company. I felt as if I hired a family member even though we never met before since he truly took ownership of his work. His prices are beyond reasonable and he doesn't charge for an extra screw or a random material other contractors charge customers. He is truly the old fashion worker your grandparents tell you about from back in the day. When I discussed future jobs with him he gladly said he would handle it. No job is too big or small for Shane. If someone would ask if I would hire him back, I would say 100%. He even warranties his work for years and you can't beat it.
Shane from A to Z Improvements did an amazing job on my project. You can really tell he takes pride in his work. His attention to detail stood out from start to finish. Everything was done carefully and came out exactly how I wanted it. On top of that, his prices were super reasonable, especially for the quality of work he delivered. He's also quick to respond and very easy to talk to, which made the whole process smooth and stress-free. And just like his motto says, "from roof to basement and everything in between," he really can handle it all. I'll definitely be having him back for more work in the future. Highly recommend!
Shane was quick to respond to my messages, set up time to met and kept his promise time. Was very quick to finish the project and his services were not over priced and will definitely use him again for future projects

Questions
Straight answers.
The things homeowners ask Shane most. Don't see yours? Call or text and ask him.
Do you offer free estimates?
Yes. Shane comes out, walks the job with you, opens up anything that needs a closer look, and gives you a written estimate that spells out what is included. There is no charge and no pressure to sign anything on the spot.
Will Shane actually be on my job?
Yes. A to Z is owner-run, and Shane is on the job site, not just at the sales meeting. He works alongside his crew, answers your questions directly, and is the person you call if something comes up.
Will there be surprise charges?
Your estimate covers the scope you agreed to. If we open a wall or pull up a floor and find something hidden, like rot or an old leak, we stop, show you, and price the fix before doing it. And we do not nickel-and-dime you for a box of screws.
Do you take on small jobs?
We do. Faucets, ceiling fans, drywall patches, a soft spot in the floor, a rotted step: if it is part of your house, it is on our list. Plenty of our bigger projects started as a small repair.
Do you warranty your work?
Yes. We stand behind our work with a workmanship warranty, and the terms for your project are written into your estimate. If something we built is not right, call us and we will come back and make it right.
What areas do you serve?
We work out of our O'Fallon office and our Wright City shop, and serve O'Fallon, Lake Saint Louis, Wentzville, St. Charles, St. Peters, Dardenne Prairie, Cottleville, Weldon Spring, Wright City, Warrenton, Foristell and Washington. Nearby and not on the list? Call anyway.
