Now that we have officially completed our remodel I wanted to thank you for the fabulous job you did. Jim from the moment we met with you we had great confidence and trust in your talents. You were so thorough at that first meeting finding our what we wanted. There was an immediate feel of integrity. We felt completely comfortable from day one. And Yuko we were thrilled with all of your talents too. You are calm in the face of any hiccups, you have great design skills, you are efficient, prompt and thorough and detail oriented. What a great combination of a company you have put together! I am thankful for our kids school years that brought us back to you.

We will go on Yelp and write a glowing report… all true.

Hope you all will enjoy a blessed holiday season. We would be glad to be a reference for any potential clients.

We contracted with Altera Design and Remodeling in April of this year to have our second Bath remodeled, with work to start when we returned in September. We were very impressed with the design sessions held in their Walnut Creek showroom with the Proj. Designer, including her attention to detail in ordering and setting out the overall work schedule. In August they advised they could start work a week early, and so they did. We appreciated their pre-construction efforts to protect the travel area to/from the Bath plus control the dust and debris. The Supt. was very friendly and helpful with minor problems that arose during demolition and reconstruction. The tile contractor performed a fantastic job, truly an artist. Overall, the project came in on-time, and under budget. We are very pleased and highly recommend Altera to our friends.

A big thank you to Altera Design once again for a great job in remodeling our master bath, updating our guest bath and installing new granite countertops in the kitchen. This is the third project that you have completed for us. We are very happy returning customers due to the fine work of each member of the Altera team. I highly recommend Altera Design to all of my friends. It is a joy working with everyone and you know you will have top quality service. We are absolutely delighted with the entire job.

I would like to thank you for doing such a lovely remodel of my kitchen. When I now think of Altera Design, I think of quality, attention to detail, and personalized service. The project manager and designer did an outstanding job. I will be happy to recommend Altera Design’s services to others.

We want you to know how pleased we are with the bathroom remodel job that Altera Design recently completed at our house in Rossmoor, Walnut Creek. We were again impressed with the high quality of the workmanship and attention to detail which resulted in a beautiful and functionally effective job. This was consistent with the excellent work you have done for us on several other projects over the past 20 to 30 years. As usual, your people were hard working, congenial and competent. Your personal attention, reliability, integrity and extensive experience have made it a pleasure to do business with you and we would highly recommend Altera Design to other potential clients. Thank you for another project well done.

– Jim & Carole, Walnut Creek

Thank you so much for providing us an excellent remodeling experience. Every step of the project went smoothly from our first meeting with you, to the excellent design support, and through the conscientious construction work. We have done remodeling the hard way but we have now enjoyed the “Altera Way”. You spoil us with your attentive professionalism and we will always recommend your firm to friends who need remodeling services.

– Carl & Susanna, Oakland

I just wanted to tell you what a pleasure it was to have Altera Design do my bathroom project. The services you provide from design to installation were all excellent. The bathroom was done on-time and looks great. I wouldn’t hesitate to use your firm again for future projects.

– Eileen, Moraga

I’d like to take this opportunity to express to you how much I am enjoying my home remodel. Your company does outstanding work. I really appreciate your thoughtful and creative design. Everything has turned out much better than I expected. It is amazing how well your staff meet the deadlines that are predicted. I really appreciate how you listen and come up with practical solutions to my requests. I am very pleased with the whole makeover of my home. I recommend you to all my friends.

My 1980s bathroom was poorly designed but functional until I developed a chronic medical condition. Not only was the bathroom no longer functional, it was downright dangerous. The team at Altera Design & Remodeling did a superb job of giving me a bathroom that was both functional and beautiful. During the design phase, they asked me questions that had not even occurred to me, and they performed extensive research to identify quality products that best suited my present and future needs. During construction, Altera Design’s staff and all of the subcontractors brought the design to life and performed all work to the highest standards of quality. I experienced none of the remodel horror stories that my friends told me I would. In fact, if every firm had Altera Design’s high standards and dedication to customer service, remodel horror stories would not exist. I love my new bathroom. Thank you, Altera Design & Remodeling!

– Kathy, Moraga

Our new countertops and appliances are all in place and we couldn’t be happier with everything. Everything occurred exactly as promised. All workmen showed up exactly when you said they would, they cleaned up after themselves, and the entire job was completed ahead of schedule. You told us that you “do things by the book so you can sleep at night.” Your way of doing business put our minds at ease and we slept better at night too! Thank you for your professionalism and high standards of ethics and quality of work. We will happily pass along our experience to our friends and acquaintances and come back to you for any further remodeling we might need in the future.

– Jerry & Sally, Walnut Creek

I am so pleased with the results, and my friends don’t believe me when I tell them that the work was done in just three weeks as committed. I have already recommended your company to several friends and am confident that their experience will be as satisfactory as mine was. I will be happy to serve as a reference to any of your future clients. Thank you again for your fine work – it’s easy to see why you are a Diamond Certified contractor!

– Lois, Walnut Creek

We love our new kitchen and upgraded living and dining area! As always, you partnered with us to come up with exactly what we wanted. You provided great design ideas and you really took the time to understand our needs. We especially appreciated the patience and creativity you showed through the numerous planning iterations that we requested. The work itself was outstanding. We are very happy with the results, and we will continue to recommend Altera whenever anyone says they’re thinking about remodeling. At this point, almost every room of our house has been improved by Altera. We look forward to whatever our next might be!

– Rich & Erika, Oakland

Steve and I felt compelled to write and let you know how much we are enjoying our new remodeled space! Six weeks after moving back in, we’re finding that we’re enjoying our new kitchen, living, dining and family rooms more than we could have imagined. The design work, the project execution and the finishing touches surpassed our expectations and made the whole remodel experience infinitely worthwhile. You listened, took note of the overall tone we were going for, and then delivered the designs that maximized the use of the space and supported the character and flow of the house. The final design we chose is livable and comfortable that I now can’t imagine this home any other way. We have a space that supports our lifestyle and entertains well – we couldn’t be happier. We hear tales of remodel woes so we are delighted to have a good story to tell.

– Stephen & Helen, Danville

I wish to express my appreciation of the great work your company did in designing and installing our new kitchen. The finished project is beautiful. Your design staff was very prompt in responding to my concerns and queries, and they were helpful and supportive throughout the construction process. I also appreciated the efficiency and competence of the construction crew. They were professional and hard working, went to great lengths to protect the rest of the house from the impact of construction, and were delightfully courteous and pleasant. Visiting neighbors commented on the neatness of the construction area. Having been warned by friends and relatives that a kitchen remodel meant weeks of inconvenience and disruption, I was pleasantly surprises at how easy it was to live in my home while the work was being done. Please extend my warmest thanks to everyone who helped on this job.

– Tom & Joyce, Walnut Creek

We were very satisfied with the bathroom remodel that you recently finished. Thank you for a job well done! The project was completed within the projected time frame and the quality of the work was outstanding. As you may recall, I was in the remodeling business prior to my retirement. In fact, I was very apprehensive in turning the project over to “another” contractor as I was sure the quality would not approach what I would have done. My concerns were needless; the project met my expectations in every way and I would not hesitate in recommending your company to anyone who is planning a remodeling project.

– Robert & Marietta, Walnut Creek

To say we are pleased is an understatement. This is your third project for us, and we appreciate your talent and helpful suggestions on what we needed to do to update our home. You have recruited a wonderful staff. We would not hesitate to recommend your work to anyone.

– Tom & Marilyn, Orinda

It was a pleasure to have Altera Design remodel our bathrooms. The results are beautiful. The manner of everyone was respectful and courteous. The initial evaluation was thorough. The work was competent, professional and on schedule. Without hesitation, we would recommend your company. Many thanks.

– John & Amy, Walnut Creek

We recently had our kitchen remodeled by Altera Design. This was a complete job from floor to ceiling, and included cabinets, appliances, wiring, countertops and sink. Not only was the job expertly done, but it was finished ahead of time. We found the whole experience to be without the usual aggravation which is so often experienced with these kinds of jobs. We would be happy to recommend Altera Design to anyone who may be considering a remodeling job in their home. Where there may be a concern about professional people, expert work completed in a timely fashion, Altera Design is a good ticket.
