Here’s what you can expect during the home building process:
Initial Inquiry
Client Introduction and Initial Consultation: Your first contact via phone, email, or website allows us to understand your vision, needs, and goals. We then schedule a consultation meeting to discuss your ideas and requirements and conduct a preliminary assessment of the project’s scope and feasibility.
Project Proposal and Agreement
Detailed Needs Assessment, Proposal Development, and Agreement: We conduct a site visit and have detailed discussions with all relevant stakeholders to perform a comprehensive needs analysis and project briefing. We then develop a detailed project proposal, presenting design concepts, estimated costs, and timelines. Once the project scope and budget are finalized and you are comfortable moving forward, you sign the contract terms.
Project Kick-Off / Pre-Construction Phase
Kickoff Meeting, Design and Planning, Permits and Approvals, Final Quote Confirmation: We introduce you to the project management team and together we review the project timeline and milestones, establishing communication channels and schedules.
We collaborate with you and the designers, architects, and other specialists to develop detailed plans, select materials, finishes, and other specifications. We then submit plans for regulatory approval and get the necessary permits and clearances.
Finally, we confirm the final project quote with all trades involved, followed by your approval and sign-off.
Construction Phase
Site Preparation, Foundation and Framing, MEP, and Finishes: This is where it really gets exciting! We clear and prepare the construction site and set up necessary infrastructure and resources. Excavation and foundation work are carried out, followed by framing and structural work.
Next, mechanical systems, electrical wiring, and plumbing are installed, and inspections and quality checks are done. Windows, doors, roofing, and exterior finishes are installed, along with interior work including drywall, flooring, cabinetry, and fixtures.
Ongoing Communication and Support
Regular Updates, Documentation and Transparency: We schedule regular progress meetings and updates, maintaining open lines of communication for any questions or concerns. You will have access to ongoing documentation of all services, materials, permits, and expenses, along with regular financial updates and cost tracking.
Project Completion and Handover
Final Inspections and Quality Assurance, Client Walkthrough, Handover and Aftercare: Lastly, we do comprehensive inspections to ensure quality and adherence to standards, addressing any final touch-ups or corrections. We conduct a detailed walkthrough with you to explain home features, systems, and maintenance tips. The property is then formally handed over, with warranty and support information provided.

What Our Clients Say
Discover the stories of satisfied homeowners who trusted us to bring their vision to life.
We highly recommend McDowell Mountain Builders to get the job done right! They are trustworthy and reliable. They transformed our out dated step up/ step down cave-like snail shaped master shower into a beautiful open and well functioning shower. Son Steve Diltz was awesome to work with! He guided us thru this process with great communication via texts, , phone calls and frequent on site visits to monitor work. From planning, to demo, plumbing, electrical, tile, drywall, paint, glass enclosure everyone was professional and courteous. Looking forward to updating other bathrooms in our home!
We hired McDowell Mountain Builders to build an entertainment wall in our home that we purchased earlier this year. The project included building the center part of the wall out 14 inches and adding tile and shelving as seen in the attached pictures. MMB, led by Steve Diltz, did a superb job in this construction project. The worker who did most of the work was one of the most careful and skilled carpenters I have ever seen. We are so pleased with the final product that we are considering hiring MMB to build an addition on the house ( if the HOA approves it).
Steve is the kind of builder who brings quality, integrity, and attention to detail to every project. Whether it's a remodel or a new build, he approaches the work with craftsmanship and care—and he makes sure things are done the right way, not just the fast way. He communicates clearly, follows through, and genuinely cares about the people he’s building for. Steve is not only a great contractor—he’s a great guy to have on your team.
We’ve had the best experiences with McDowell Mountain Builders. Over the years we have worked with other contractors and it’s always so stressful and unorganized. We worked with Steve and had great communication. The work is quality and beautiful! We would 100% work with them on future projects. Highly recommend!
MMountainBlders has worked on two projects for me, my private residence & a rental property. Not only are all these people fun to be around, fun to watch work, the finished product is amazing. From a complete demo & rebuild of two bathrooms, to tongue & groove ceilings in a living room, kitchen/dining & outside patio, to turning an unused bedroom into a sewing studio complete with 12 ft library ladder, these dudes are good! Much of this work I call works of art. Always on time, worked nonstop start to finish & w complete clean up. You couldn't do better anywhere.

McDowell Mountain Builders did an excellent job with our large remodel project. They were meticulous, timely, have great relationships with their subs and fantastic, skilled team. Highly recommend David and entire team.
