"Platinum General Construction LLC was contacted after two initially hired contractors were incompetent in providing the remodeling services needed for our bathroom remodel in Dec/Jan 2025. Platinum stepped in and completed the work on time and as quoted. David was our primary contact. He was great as respects communication, working through issues, and coordinating with subcontractors. The remodel included heated tile floors, a curbless shower, toilet install, and beautiful tile work. We were pleased that Platinum got our project back on track and finished after dealing with the mis-steps of our original contractors."

"The nicest and hardest working construction crew and company Iâ ve ever dealt with. Extremely excellent customer service. Employees showed up several minutes earlier than expected every morning. The large crew always work together along with the boss doing a lot of grunt work himself. They laughed and really seem to enjoy doing their job together as a team. We could not be happier with the driveway that we have waited for for 10 years."

"I interviewed several contractors for my addition and addition and I chose Andrew because I felt like he was straightforward with the project and the risks that come with a remodel of an 80 year old house along with the primary suite addition. Through the design phase, we never felt pressured to make decisions, but were kept informed of the timing of the project and when we needed to make decisions in order to schedule the project in a way that minimized the impact to our family. Andrew walked us through each item in the contract and worked with us to make changes to fit our budget and kept us informed on what we could expect for changes for a project like ours. Once we were out on contract, Andrew helped push permits through county and kept us informed on what we could expect for duration and timing of the project. Once the work began, Andrew and his right hand man Rod worked efficiently and coordinated the project beautifully to minimize the amount of time that we were displaced from our home. Thoughtful suggestions were made to deal with the numerous issues that come with renovating an 80 year old house and Andrew supported my questions on cost impact and the criticality of each change to keep me informed so that we could make decisions that we felt comfortable with. Andrew and his team of subcontractors were all very friendly and respectful of our family, never making myself, my wife, or 3 kids feel unsafe at any time. Even with the changes to the scope of work, Andrew and his team made good on the timeline of the project, completing everything in 3-4 months as promised when we started. The layout and design of the remodel and addition have surpassed our expectations, everything that we did has really made our home both more beautiful and more functional. I would highly recommend Treiber Building and have done so to several family members and colleagues at work. The experience was as positive as I couldâ ve hoped and the results are outstanding."

FAQs for addition to existing structure building service projects in Snoqualmie, WA

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
