"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."

"Very honest company, and complete the job in a thoroughly way."

"Emil did a wonderful job of explaining all aspects of the project during the sales presentation. Anthony and his painting crew did all that was contracted and more! As the job progressed, it was evident that more trim work was necessary. Anthony listened patiently and completed the entire painting job ahead of estimated completion."

"The work involved demolition of 400 sq ft garage and building out close to 1000 sq ft structure that included new garage, bed, bath, laundry/utility room. I took 5 quotes from different contractors and choose R & M Construction. Their quote was very detailed with down list items which gave me confidence that the team knew the job and could execute and how the cost was calculated and it gave me flexibility upgrade/downgrade listed items. During execution of the project, the team was very professional and did a great job! we lived in the house during construction and they were very accommodating. No hesitation in referring them."

"Extremely professional and did an amazing job"

"This experience was my first remodel and it was fantastic. Sarmento Bros were very professional and kind. They guided me through the renovation process.

"We hired EA Home Builders to renovate our guest bathroom - and they did a great job for us. The two gentlemen they hired for our job were skilled professionals. They said it would take about a week and it did these guys showed up on time every morning and worked all day (with a half hour break for lunch). And at the end of each day, they meticulously cleaned up the inevitable mess of the day. Without a doubt I would use EA Home Builders again for our next project."

"Dustin did an amazing job."

"Mr. Wilson and his partner performed a perfect job on repairing my door jam and installing a water filter. The repaired door jam looks new again with no sign it has ever been damaged. The price is very competitive and offers a good value to the money. The official distributor of the water filter quoted twice as much to perform the same job. We paid them $40 tips after the job is well done."
