New Construction

We have had the pleasure of working with Bobby Caldera during the planning and construction of our new home on Tulloch Lake. We highly recommend Bobby to anyone who wants their house constructed to the highest quality standards. This includes everything from design of the house, to the grading of the lot, to the construction of the home.

He, his crew and the subcontractors he uses are top notch professionals with outstanding skills and pride in their work. The take each project personally and we were always amazed and completely satisfied with the attention to detail and the quality of the work they performed. We relied on Bobby's experience and guidance to make literally hundreds of decisions during the construction. We asked him and he offered his opinion on the many details which helped us immensely to make those decisions. He got to know our tastes and sometimes Bobby himself would make suggestions which we never would have thought of. Those suggestions turned into important changes, which we love, in the construction of the home. His goal was always to make us happy with the work and whatever decision we made, and he accomplushed that goal with us.

Although our new Tulloch Lake home is over 110 miles from our existing home in Fremont, communications with Bobby is easy. He as always available to us through telephone or email to discuss construction issues and details. Even though we made frequent visits to the contstruction site, he hept us apprised of the construction progress through phone calls and by sending emails with photos attahced. His billing was very detailed, in Excel spreadsheets, which followed the line-by-line format of the construction estimate he made, and was backed up with receipts. This format made it easy to track costs against construction estimates.

Finally, and most importantly, Bobby proved to have the very highest integrity possible. He gained our confidence and trust. He always does what he says he's going to do and is completely reliable. If you want to be completely satisfied with your construction project, whether big or small, choose Bobby Caldera. We highly recommend Bobby to you. He will make it happen and meke you proud of your home.

I have worked with several contractors in the SF Bay Area and Calaveras County on projects big and small. Caldera Construction is one of the most professional, cost effective and efficient firms I have ever encountered. Bobby is a true hands on professional and he responds honestly and in a timely manner at all times. He gave great advice, outlined options and often referred me to money saving opportunities, even if it meant a lost revenue opportunity for him. I have complete trust in Bobby and his work and I would gladly recommend them to anyone considering a quality construction project.

Bobby and his crew built 2 small outbuildings at our vacation home at Lake Tulloch. We chose Bobby because he had previously done a major remodel for some close friends and also built two beautiful homes adjacent to ours at the lake. We were very pleased with the work Bobby and his crew did for us. Bobby and his crew are true craftsmen and take pride in their work. They work fast and get things done on time and in budget. They are clearly the best choice for a builder in the area.

We had a great experience with Caldera Construction and we highly recommend him. He has excellent relationships with his subcontractors and Caldera jobs always get done on time. He is organized, efficient, professional and keeps the property grounds clean throughout every stage of the project. Bob is easy to work with and most importantly, he stands by his work. We built a custom home from top to bottom with Caldera Construction and would do it again.

It was great working with Bobby. I can't say enough good things about him in a small amount of space! He built our vacation home which is about 150 miles from our main home. It was critical for me to have a contractor I didn't need to check on frequently due to the distance between homes. Bobby was helpful at every stage of the project. He is reliable and stands behind all his work. The quality of his work, his crew and the sub contractors he uses are top notch. Guests to our vacation home are always commenting on the quality and attention to detail he put into our house. He delivered on time and within budget. We are very happy with our house and couldn't have asked for more in a contractor. If you are building a house over 100 miles from where you live or just down the street, you'll want him as your contractor. We highly recommend Bobby!

Bobby has built 2 homes for us. He's a pleasure to work with an has exceeded our expectations each time. I would never use another builder!

Bobby Caldera built for me 2 homes, 3 remodels and my office building. All the projects were completed ahead of schedule and on budget. Getting the job done ahead of time saved me a lot of money. His crew keeps the work site clean and his subs are on time. Other contractors hope to have his reputation someday.

We had the pleasure to work with Bobby in building a second home on Lake Tulloch in 2004. Having built homes in the past, we were very concerned about enduring the construction process for a home more than 100 miles away from where we lived. We built a large home there (7 bedrooms, 5 baths) and also found it hard to believe anyone could deliver on a 1 year construction schedule. Our home was built on-time, in-budget with not a single issue. All along the way, Bobby kept in constant communication with us, kept us involved in key decisions and accommodated changes and incorporated ideas like we had never before experienced in building a home. Six years later, Bobby stops by the home regularly to "check things out" and makes himself available for any small issues or needs that may arise. We are very careful about making recommendations for anyone but, without reservation, make an exception for Bobby Caldera. I cannot imagine anyone would ever consider another contractor if he was available for the job based on our amazing experience.

The summer has passed so quickly. Our wonderful new cabin at Twain Harte has never experienced such activity. All of our family, including all three of our sons and their kids and our friends, too, have thoroughly enjoyed the results of all of your efforts and expertise. Scott and his new bride, Christy, enjoyed the new “honeymoon suite” downstairs on several occasions. The cabin looks great and is so nice to use. You did such a beautiful job of blending the old and the new.

We appreciate the way you worked with us. We loved getting the pictures via email of the progress. You always took care of all the details beautifully. The painter did such a great job with the special “green” in the living room. Your guys did such a good job on their part. We especially like the sunburst in the back deck railing. The vinyl job was incredible. I see why you wanted to wait for him. All in all, you did a fantastic job and we appreciate everything you did. You were a pleasure to work with.

We would be most happy to serve as a reference for you at any time. We are very happy clients. I hop you will stop by some time when you are driving by and say hello. We would love to see you and have you see all the things we have added inside.

We are looking forward to spending more time in Twain Harte this winter, too.

My wife and I would like to thank you for the wonderful service we received from you on the recent construction of our new home in Twain Harte. Thanks to all the employees and you for their desire to please us and the friendship and courtesy that you and they showed. I would be pleased to recommend your company to anyone in need of your services. Thank you again.

My folks are very pleased and excited about the new home you designed and constructed for them.
I have been amazed at the speed at which you built the home. From start to finish, the process lasted less than four months. Most importantly, the construction methodology and quality have been beyond description.

I don’t know if we ever told you how very happy we are with our home. You did a wonderful job, and we have praised you to everyone we know who is even thinking about building a home. The nicest part is, not only did everything go smooth, we remained friends after construction was complete. That’s a rare thing for most contractors around here, or for that matter, anywhere. If you ever need to use us as a reference, please do not hesitate to do so.

Just wanted to say thanks for the great team you put together on my house. Every subcontractor was so caring, especially your painter. The time you personally spent with me going over things, was above and beyond what I ever expected.

Ken G.

Thanks for the great job on the house. Things went very smooth. Thanks for all of the extra input along the way. I thought I had everything I wanted on our original plans, but with your guidance and thoughts we ended up with more than we expected. Two of my favorites are the outdoor kitchen and the radiant floor heat.

Additions & Remodels

I am delighted with the project and I understand all of the costs. At last I got everything that I ever wanted. You are a delight to work with, as well as your team and and your subs. THANK YOU!

My husband and I took a drive to the cabin yesterday. OMG, everything looked so good! The deck is beautiful! So sturdy and excellent craftmanship. We loved the extra space on the main level. The balconies looked so good too. And I loved the paint color! It's darker in person than in photos which is exactly the look we were going for. My husband remarked what nice work you did (and he's very particular). Oh, and the repair work on the side of the house looks great! It doesn't look like the same house. I left feeling so happy. So, thanks again for everything. All the best to you in the New Year.


Monte Grande Heights, CA

You and your crew made our dream come true. Thank you for how self-sufficient you were in managing the project. You made the whole process so hassle-free making it a joyful experience. It doesn't seem to be a reality that we have a "home" now given each stage went so quickly and seamlessly. It amazes us when we look at the pictures from the awful demolition stage to the siding being complete. Thank you for managing the project so well!

I also love your porch arch! You did it just as I envisioned it! I wanted it to be a soft radius as you did so thank you!

Please thank your wife again for us in all of her work sending us the pictures. They allowed us to be a part of the whole process (without the dust and mess)!

We will be up there this coming week and can't wait to see it in person again.

We contracted with Caldera Construction to build a small addition to our cabin in Cow Creek Recreation Residence Tract, located in Stanislaus National Forest land. Part of the project included modifications to some parts of the existing cabin as well as raising the building approximately 18 inches and constructing new concrete foundations. Dealing with a 63 year old structure that had not been altered since it was constructed required skill and sensitivity, which Caldera Construction demonstrated. Scheduling was also an important factor since the structure had to be completed before the winter snow made access impossible. Work stared in August 2010 and finished in October 2010 on schedule. Bob Caldera was very considerate of our concerns and making accommodations for us to use the cabin while work was proceeding. We were quire pleased with Bob and his crew, who were very congenial and pleasant to be around and were very efficient on the job site. And the left the site exceptionally clean when they were done. We would be very happy to have Caldera Construction do work for us again and hope the opportunity presents itself in the future.

We worked with Bobby on a major addition to our home. During the construction, he kept us fully informed of progress, always showed up to meet with us when he said he would and gave us plenty of warning as we approached decision points. Bobby was very hands on, stood behind his work and handled all of the inspections without a hitch. It was obvious to us that his crew and subcontractors cared and took pride in their work. Every step of the way, the results were of the highest quality. Something that seems simple but sets him apart from the crowd was that his crew cleaned up the work site at the end of each day. And most important, he stuck to the plan - cost and schedule. We would definitely use Bobby again!

We have used Robert Caldera Construction to remodel our home at Lake Tulloch. Bobby and his crew are the very best. They are always on time, work very hard and go beyond what is expected. They all do the work as if they were working on their own home. Bobby is extremely organized an has an eye for all details. He is knowledgeable and helpful in all aspects of the project. Everyone that works with him and for him are always very professional, yet very nice people who become your friends. We would use Robert Caldera Construction to build a house from the ground up if we had the opportunity. Anyone who has Bobby work with them in any home building capacity is very lucky.

Terry & Jackie M.

Thank you for a great job on our house addition. Your carpenters and subcontractors were attentive to details as well as being courteous and responding to our requests. We are quite happy with the results.
Thanks for all your efforts. I will definitely recommend your Company to people who will be seeking construction expertise in the future.
