"Great! Excellent communication from the project manager, work crew went out of their way to do a great job and to pick up materials for me when delivery wasn't possible. They were punctual, cleaned up at the end of each day, tried to minimize the intrusion as much possible, and were really nice guys, great to work with. Work was done on time and on budget. Kitchen looks great and I couldn't be happier. The price was for labor and raw materials. We supplied the cabinets, lighting, countertops, sink, appliances, and windows. We also decided to get the attic insulated at the same time at their suggestion- that addition was not included in the cost below (I don't remember how much it was but it was reasonable.) Here's what the work included: Demo existing kitchen including walls, floor, ceiling and windows. New electrical sub panel and wiring in kitchen Gas line added to kitchen (gas was already in the basement area) Installation of new walls, floors, ceiling, windows, doors, trim Installation of cabinets, countertops, appliances, sink Painting Attic insulation (additional)"

"From the beginning, MCA offered excellent help while shopping with us to select materials for each room.  
They allowed space to express our likes and dislikes, while offering experienced suggestions when we were in doubt. 
Prudently, MCA was sure to order and receive all materials before beginning work.
MCA seems quite discerning in selecting their crafts people and associates, like painters, granite finishers, and shower door 
builders.
We found their team of workers to be honest, friendly, highly-skilled, and hard-working.
We learned and respected -- as we had heard widely -- that construction and remodeling has inevitable timing delays and surprise technical puzzles to solve.
Also MCA had days when other jobs and needs delayed our progress.
So at our home, there were days when nothing happened, and balancing moments when one, two, or more craftsmen were on the job. 
Money-wise, the MCA cost estimate was 30% less than the highest competitor.
They were totally true to their financial contract, even when unexpected, added modifications were needed.
Were we to identify MCA's growing edge, it would be improved communication and more focus on continuity to begin and finish in a slightly more timely manner.
We know that is easier for us to ask than it is to fulfill in the challenging world of remodeling and staffing.
It really does take a village to coordinate and complete all of the various requirements -- material choices, teamwork, electrical, plumbing, tiling, and much more.
There are inconveniences, surprises, and a need for patience.
In the end was it all worth it, and would we highly recommend MCA?
We surely would, YES."

"I had the pleasure of working with Ariel from My Construction Group for a fairly large remodel (two balconies, one room addition, and one great room expansion) project on my home. I was very pleased with the completed work and even more impressed with their attention to the customer experience. This truly differentiated them from other contractors I have worked with. I would highly recommend My Construction Group to everyone."

"We hire Geico builders for our kitchen remodeling project, and I'm happy to share my experience: Working with Zaya and Geico Builders was a great decision. They were professional, friendly, and easy to work with. From the start, the process was smooth and efficient. The craftmanship of my remodel kitchen and attention to detail were exceptional, and the end result far exceeded my expectations. From the design phase to completion, their communication was excellent, and I felt completely at ease with them working in my home. The design solutions completely transformed my kitchen, making it both functional and beautiful. I highly recommend Geico Builders for anyone looking for a stress-free and satisfying remodeling experience."

"We made the best decision when we hired Cerletti & Kennedy Design Build to do our bathroom remodel. They are professional, knowledgeable, efficient and reasonably priced. We had a downstairs half bath totally remodeled to a full bathroom with a walk-in curbless shower. I had in mind a certain look for this remodel and Cerletti & Kennedy Design Build listened to my ideas and we worked together to implement them. We love the fold down shower seat & under floor heating system. During this construction, they found pin holes leaks from the upstairs plumbing. We were happy they offered cost effective solution to fix that issue too. All crews were professional. Ruben, who was on the job the most, is exceptionally skilled and did a fantastic job on our new bathroom. We highly recommend."

"The Bayside Builders Group is one of the best companies I have ever worked with. They were so professional and helpful on my bathroom renovations. They worked on 3 baths in our house. My wife wants it remodeled and converted into a more fresher space. They were able to achieve just that. Great work!"

"We recently finished a total remodel of our home in Martinez, working with Accurate Home Remodeling. We went through the bidding/estimate process with a handful of local contractors and found AHR to be the most responsive and fairly priced. Miles at AHR was very responsive and uses an app on the phone that makes communication, documentation, photos easily accessible and in one location. Believe meâ ¦this was super helpful to be able to refer back to discussions, ideas, prices, materials, etc. as the project went along. Our project was on budget and on schedule, aside from the additional and change orders that we presented Miles with during construction. Overall I would recommend AHR if you in the market for any type of home remodel/renovation project."

FAQs for addition and remodeling projects in Port Costa, CA

The proper sequence of a kitchen installation starts with laying the foundation and structural framework. From there, you need to establish utilities like plumbing, wiring, and gas lines, then install cabinetry and countertops, and finally finish with flooring, painting, tile backsplashes, and lighting. A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
