"I am so happy I hired Unique Home Design & Remodeling for my bathroom remodel. I had never worked with this company but hen I saw my friends remodeled bathroom I asked him for contact and he gave me contact of this company. They were honest from start to finish, my new bathroom looks even better than from my friends and price was reasonable. Highly recommend!"

"Had him rebuild an old patio cover in my yard. All we kept were the posts and two beams. Replaced all else. Came out very nice. Couple months later had him do some porch railing and window sill repairs on a rental house my mother owns. Nice work, very fair price. Will definitely use him again."

"Excellent communication. Execution was outstanding. Very able people worked hard and long and got the job done in a most timely manner. Detail work was first rate. When something needed to be adjusted that was done. Some of the adjustments were just amazing. (We had a built in Murphy Bed installed that did not quite fit the space. A tapered base board kept this from looking awkward. Amazing!) Also all the folks were very nice. Add reasonable pricing and there is nothing else to ask for. I liked them so much that when my daughter did a major remodel, I recommended Baja, and she too has been super happy with the results. Where I come from, passing a vendor on to family is the highest form of praise."

"Our goal was to build a structurally safe garage storage loft. Juan and Julian were a great team to work with. They were very professional and organized- they gave us a quote and clearly communicated what the plan would look like from beginning to end. They guided us on the items that we needed to buy prior to starting the work in order to complete the project within the estimated time. They suggested modifications that were minor fixes but made the layout make more sense in terms of placement. Their crew finished a day ahead of schedule. They kept a clean work site and the quality of the results were great. I would gladly work with them on another home project in the future!"

"I couldn't ask for more from Future Vision Remodeling. I don't know much about construction and have had only one other experience with a project that didn't go so well; Sami immediately put my mind at ease. I live in a 1B/1B condo and wanted to do a small project upgrading my bathtub, adding tile to the walls, and replacing my vanity countertop and pocket door. The quote was fair, the work quality and timely, and I was able to have peace of mind while I went about my work day. Sami went out of his way to be flexible with my work schedule/commute when we needed to meet in person and made me feel like my job was just as important as any large home remodel. I had a very good experience with Future Vision Remodeling and will definitely call them again for future projects."

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
