About Alta Casa

Alta Casa Remodeling – ADU Builder and Home Addition Specialist in Vancouver, WA

Alta Casa Remodeling is a remodeling contractor based in Vancouver, WA, offering a range of home improvement services with a particular focus on accessory dwelling units and home additions. Their work is aimed at multi-generational families looking to expand their living arrangements in a practical and well-designed way.

As an ADU contractor, Alta Casa handles projects that include in-law suite construction, garage conversions, and the design and build of fully independent accessory dwelling units. Whether a homeowner needs a granny flat in the backyard or a self-contained living space attached to the main home, Alta Casa works to deliver solutions that fit both the family's needs and the existing property.

Their approach as an ADU builder centers on creating spaces that balance privacy, comfort, and functionality. Each project is developed with attention to how the new addition integrates with the original architecture of the home, rather than simply adding square footage without consideration for design continuity.

  1. Kitchen renovations
  2. Bathroom remodels
  3. Full home makeovers
  4. Custom home additions
  5. Garage conversion to living space

As a detached ADU builder and backyard cottage builder, Alta Casa takes a collaborative approach to each project. They work directly with homeowners from the initial planning phase through to completion, helping clients make informed decisions about layout, materials, and finishes.

Their process is structured around clear communication and a defined plan before any work begins. This includes understanding the homeowner's goals, developing a customized design strategy, and executing the build with attention to detail and respect for the home environment.

Company Background and Values

Alta Casa was founded with a design-forward philosophy, drawing from European heritage and experience across North America.

"Excellent service from Alta Casa! They did a full 'no-dishwasher to dishwasher' conversion for us, including custom cabinetry work, electrical, and plumbing. The team was efficient, professional, and left our kitchen cleaner than they found it. Were thrilled with the result and will absolutely be hiring them again for our next remodel."

"I am currently going through an entire home remodel 3 bathrooms, kitchen, living room, new doors and trim, fireplace, laundry room, etc.. I had five 5 companies quote this job. After all the back and forth and several meetings, I ended up narrowing down my TOP 2. Both were OUTSTANDING! Alta Casa was one of the these TOP 2. Although I didnt choose Alta Casa, I am happy to leave a great review because their pricing was in the TOP 2 and the whole consultation process was in the TOP 2 as well as many other things I loved about them. Dave my salesguy was outstanding - knowledgable, easy to talk to, listened very well, and genuinely cared about my remodel. Their website and portfolio of past jobs are second to none. If you are going to pick 2-3 GC's to quote your quote, Alta Casa must be one of these. I always felt they were being truthful with me and were looking out for my best interest. You will be happy after your first consultation. There was no "hard sell" or "sign now" which other companies do! 5 STARS!!!!"

"Tim and his team were amazing through the whole process. My wife and I researched many options all proving to be costly and time consuming with shipping and delays. Tim met us at his showroom and gave us a wide array of options and accommodated our busy schedule. He ensured we got the product exactly when he said it would arrive and in perfect condition for a lower price than anyone else. For anyone considering this type of project, do yourself a favor and go with Alta Casa Renovations and Tim for a hassle free experience and a great product!"

"Of all the renovation projects we have done, this was the highest budget and level of risk we ever contracted out for, so we consulted multiple sites and read reviews before narrowing the list of professional contractors to a handful and reaching out for consultations. Alta Casa immediately stood out with their excellent responsiveness and communication, and the others gradually self-selected out to the point where we were ready to proceed. How would that translate over the course of the project? Design process: The Alta Casa team listened to our needs and incorporated them into the design, asking appropriate clarifying questions along the way. Our priorities yours may vary: - Keep original footprint and walls intact - Increase storage, but better use of space lose the peninsula and soffits - Increase lighting: overhead and under-cab - Functional usability of cabinetry - Coffee bar - Baking station Execution on Delivery and Project Management: - Scope: We reached an initial agreement and everything that we decided to add was appropriately and promptly covered with a change order. - Schedule: Coordination of subcontractors executed well, work was done in sequence without dependency-related problems causing delays or rework. - Budget: The budget grew as we added and communicated prioritized items, but always under control and confirmed. - Communication and Coordination, Adapting to Changes: We all know that "little hiccups" happen, and you never know what you're getting into until the walls are opened up, but the frequent and open, honest dialogue enabled us to discuss what was learned, define options, and make the choice with which we were most comfortable. - Skills and Materials: Top quality, see for yourself in the photos. Final review together to confirm successful completion and satisfaction. Summary: Being without your kitchen for several months is notoriously stressful. The team at Alta Casa, their subcontractors, and external referrals were all extremely professional and repeatedly went above and beyond to deliver us an amazing result. I would choose them again in a heartbeat, offering my highest recommendation. If I could give them 6 stars, I would. They were that good. If you are in that spot, trying to choose a contractor you can trust to deliver your project, give Alta Casa a chance to win your business."

"The Alta Casa crew did a wonderful job on our bathroom re-do! They helped guide us on products to use, cost savings and more. What I was most impressed by was the professionalism, "clean-cut" workers that didn't use foul language in our home, keeping us in the loop of what work would be done and when, etc. We love our new bathroom and would hire this company again and again!"
