Our team helps home owners design their bathroom to combine the best of functionality, aesthetics and comfort. We make your dream our mission. We are craftsmen with over 30 years of remodeling experience and are passionate about transforming ordinary spaces into havens of luxury and convenience.

"They started in mid-October and promised to be finished 12/15. They sort of finished 1/28. They promised me that all three of them would work on my projects simultaneously and that they would get everything done quickly. Instead, there was usually just one guy working on things. The shower pan that was installed in my walk-in shower was done incorrectly so it leaked for about a month before I caught it. They did come back to fix it. The measurement of my kitchen was so off that I had to send back two cabinets and purchase another cabinet to make things right. They screwed up the shower door installation in my main bath so badly that it was unusable. That was in January. They eventually came back in April to fix the messed up tile in that shower and said they'd be back in a couple of weeks to finish things up. They didn't offer to come back until last week. By that time, I had already had all the little things and the new shower door done."

Sustainability is at the heart of everything we do. As a steward of our outdoor environment we understand the important role we play. We ensure our work minimizes maintenance, water usage, material transportation, and waste. These principals guide all of our practices to ensure that the air, water, and soils are protected and enhanced. Our firm was founded years ago by Ryan Sarvis to create a turn-key landscaping company that could deliver the highest quality spaces with excellent communication and service to our clients. Ryan has an unrelenting love and passion for landscaping as a 3rd generation landscaper. His devotion to excellence in all areas of the client experience reverberates through all levels of our team. Our founding principles endure today and are at the heart of our operations. We use our in-house carpenters, stone masons, lighting/irrigation tech, and other landscaping craftsmen to ensure the best quality work that is implemented in a timely manner. By avoiding multiple subcontractors, we seamlessly complete projects that require multiple disciplines or facets without delays. Our craftsmen have been trained in the "Green Spaces Way". These sets of standards allow us to stand confidently behind our work with an industry best five-year warranty. Our multiple awards from 425 magazine, Angie's List, Houzz, and local industry groups are testaments to our diligence for the highest quality work and client satisfaction. Our reviews from various sites speak to the service that you should expect when investing in your home's outdoor space. Please contact our design team to learn all about the potential your outdoor space holds.

"The work they did is top notch, I love our patio and couldn't be happier with what they've done with the space. They did a lot of work for us over two months to build a patio and beautiful back yard. We love it. That said, our home is a 70+ year old house in Magnolia with concrete pipes. A year or so after they did the work we had a backup. After the plumbers came out they found that a section of the piping had been crushed by a large rock that had been set while they were regrading the area. The repairs were ~15k all said and done then. I contacted Ryan and he looked into their insurance covering it and they weren't going to do it out of pocket. I value my time more than money and I let it go, and Ryan had some guys come out and fix the area that had to be torn up for free, least they can do. Well after they were done the plumbers spotted another crushed section that lined up and should be 'okay'. Fast forward a year, it wasn't we had another backup. They cleared it and we just had it fixed with another 5k bill. Ryan had said they wouldn't do it for free but 'hours and material'. They didn't give me a quote I shrugged and assumed it would be a mornings worth of work. They came out and spent two days, and they just handed me a bill for another $3200, to clean up after damage they caused and I'm paying for."

"Atlantic Tile & Granite did a great job on our kitchen countertops and island in our old house in 2013, so we had them to do the countertops and island for our newly built house (2023) as well. Once again, the outcome was nothing less than fantastic."

FAQs for second story addition building service projects in Seattle, WA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
