"Kevin did an amazing job, responded right away & accommodated my schedule.He built a wall, creating an office space.He made sure I am aware of all the steps & took pics of the frame and insulation before drywall was installed. He moved the thermostat and installed 2 outlets on the new wall. He painted the new room, living room, hallways and 1 bedroom. The paint underneath was dark blue, so he made sure to apply enough coats to cover it perfectly. He removed an iron chimney and covered the ceiling, also bringing the floor under the chimney to the same level as the rest of the living room and covered with hardwood. He installed a fan on my vaulted ceiling in an angle and a new light in the office space and left the house clean of all debris. I am beyond impressed by the quality of work and professionalism he showed from start to finish and I will definitely hire him again.He is reliable, accommodating, respectful & hard working.Hire Kevin without a doubt.You won't regret it."

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."

"We were so pleased with the quality of work performed by Tall Pines Construction on our large, extensive bathroom remodel that we hired Tall Pines to install new flooring--engineered acacia wood--throughout our entire home (except for the bathrooms). It was a huge job, but we're so glad we did it. The floors look like a work of art. While doing the floors, Tall Pines also changed all our floor boards and interior trim around windows and doors to give our house a sharp new appearance and feel. The crew were a delight to work with and to have in our home. Late August while having some siding work and shingle replacement done on our exterior, rot was discovered in two areas. We called Tall Pines, and they quickly came out to the house, assessed the damage and repaired it before the rains set it. We believe in relationship building with service companies.Tall Pines is a company you can work with for the long run. We highly recommend them."

FAQs for second story addition building service projects in Mercer Island, WA
Converting a vaulted ceiling into a second floor requires three to six months from planning to completion. The process begins with several weeks of design and engineering, followed by permit applications, which vary in processing time by location.
Construction itself spans several months, including framing, systems installation, and finishing work. Weather conditions, contractor availability, and inspection schedules can all influence your project timeline.
Several factors could make your conversion challenging or impossible. Inadequate roof support structures, insufficient foundation capacity, or problematic truss configurations might require prohibitively expensive modifications.
Some homes lack the minimum ceiling height (12 feet at the lowest point) needed for functional second-floor spaces. Building code restrictions in your area might also limit conversion possibilities, particularly in historic districts or homes with specific architectural designations.
Begin with professional assessments from both an architect and a structural engineer who will evaluate your home's specific characteristics. They'll examine existing framing, measure available headroom, assess load-bearing capacity, and identify potential obstacles like HVAC ducts or plumbing vents.
These experts will also review local building codes to determine feasibility. Their preliminary analysis provides crucial information about structural requirements and potential limitations before you commit to the project.
Whether you'll need temporary housing depends on several factors, including the project's scope and your tolerance for construction disruption. Major structural work creates significant noise, dust, and potential utility interruptions that many families find challenging to live with. Safety concerns may also arise during certain construction phases.
Some homeowners successfully remain by isolating the construction zone and establishing clear work schedules. Discuss living arrangements with your contractor early in the planning process to make informed decisions.
