Second Floor Addition Builders in Alamo, CA

"Me and my husband looking for contractors, after long research we found GPI Builders and they provide the best service. We did remodeling to our bathroom and master bedroom. They also gave us a great design! The crew pay attention to every details + responsive very quickly to any issue we had. Thanks!!!"

"He did a great job. Great customer service and he used good materials. My mother-in-law loved his job. Perfect pricing."

"Creation 7 worked for us on a kitchen and bathroom remodel, but also an addition (we expanded the original kitchen by 110 sqft and added a 110 sqft bedroom on the second floor). Eyal and the team know their stuff, and gave us a great service. The result is amazing and we could not be happier."

"Gabriel and his team did a Fantastic job.!!!"

"They really listened to our needs. I like that they can put my vision to work and that I don't have to be there to make sure everything is perfect, as they are looking out for me and want to do a good job."

"Their building design services offered a distinctive blueprint that maximized every inch of our space efficiently. It's a perfect blend of creativity and functionality, tailored to our lifestyle and needs."

"Yes. The remodeler was on time, worked efficiently, cleaned up after himself, and because Eric was experienced in remodeling, he knew exactly what to do so everything went smoothly. Thank you. The bathroom looks great!"

"I hired Hagenbach Construction based on a referral from my cabinet vanity vendor who I've done business with 4 years prior. John, his wife Amy, and his crew were AWESOME and the finished bathrooms can easily make an HGTV remodel or magazine feature. They were far better than I ever imagined. I wish I can post some photos here, but hopefully, the finished bathrooms will grace his website. My project involved two bathroom remodels - a master and guest (and the only two in my single story home) over a period of 7-8 weeks. The master bathroom was a total demo of the existing 200 sq. ft. space, on a slab floor and what we believed had post tension cables. It was a complex project, in my opinion, and one I waited on the right contractor to help me with. John was meticulous in the planning of the work, review of my design, and in every aspect of the tricky construction. While I had an initial design from the cabinet vendor, John validated the measurements, size of vanity, walk-in shower, shower seat and niches, placement of the freestanding tub, canned lights and wall sconces, vents, the new pocket door and bathroom door, etc.. The floor tiles and shower tile accent were very intricate, utilizing basketweave floor tiles and a herringbone shower tile accent. They were installed perfectly. John personally laid the shower tile accent on a piece of plywood for me to see and finalize before installation. The wall and placement of the carrara marble subway tiles and chair rails were also carefully planned across the room, so that he can plan for where the cut pieces were going to be. On the 6' x 6' walk-in shower, he assisted in getting me the best neo-angle configuration, with the best 30" door placement. He also guided me in the options for best hot water availability. There is nothing I would change in these bathroom projects and John and his crew were hardworking, meticulous, conscientious about the remodel inconvenience and were always a pleasure to work with. They always showed up early or when they said they would. I would recommend John and Hagenbach Construction to anyone for any project. Contractors like him are a gem, and few and far between. It shows that he and his crew take pride in their work."

"A great contractor, shows up on time and really accurate with the pricing."
