"This contractor was recommended to me by another contractor that didn’t have the time for my project. Things that really stood out: 1. He was very thorough during our walk through and with his quote. 2. I had a vision of what I wanted and although I had pictures to help, he did a great job completing everything I asked and it was perfect. 3. The job was completed on time and was very reasonably priced. 4. When I wasn’t sure of the best product to use but knew what I wanted it to look like, he would offer options from lower priced, mid-range, and higher-end. Gave me pros and cons and left it up to me to choose, and I appreciated the options. The job was a remodel of the living room, dining room, and entryway. He replaced four windows and the front door. Closed off one wall and made the entry on another. Replaced the entryway closet with a built-in. The walls, ceiling, and trim were updated, installed, and painted. He also did the flooring"

"Jonny was professional and had great ideas in keeping the structural integrity of my Small remodel. We wanted an entry widen so he had to put a new support name and it looks great! Also it enclosed a room and made a den and we love it! And added a bigger pantry. I feel like this remodel is built better than my home is. He was on time and efficient. Highly recommend."

"Wes was amazing to work with. His products are top quality at a reasonable price. No wonder there are many home owners these days are working with him. He made it even better for us when he called me to let me know he can install the patio cover 2+ weeks ahead of our initial schedule. These made our weekend and the weeks that followed...Overall I would highly recommend working with Wes if anyone is thinking about putting a cover in their patio."

FAQs for addition to existing structure building service projects in Walla Walla, 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.
