"Amazing Experience Couldnt Be Happier Working with Blue Lake Construction was one of the best decisions we made for our home and our kids. After months of frustration with another smaller company that we originally signed a contract with and waiting over four months with zero progress, only delays and excuses we were honestly exhausted and disappointed. That all changed the moment we spoke with Leo from Blue Lake Construction. From the day we signed with Blue Lake to the day the project was fully completed was less than three weeks, which honestly felt unbelievable after what we had gone through before. Leo immediately understood our vision and delivered the exact design we wanted an outdoor play area raised about 8 feet above ground, built like a flat, safe platform for our kids to enjoy. The project included: A treated wood frame for durability and safety A plastic cover for protection from the weather A secure gate to keep the kids safe Clean, solid craftsmanship throughout The attention to detail was impressive. Safety was clearly a priority, and the final result looks amazing and feels extremely sturdy. The work was done professionally, efficiently, and with great communication every step of the way. No guessing, no stress, no surprises. On top of that, the price was very fair, especially considering the quality of work and how quickly everything was completed. You can tell Leo and his team actually care about doing things right, not cutting corners. Our kids absolutely love the space, and we couldnt be happier with how everything turned out. Because of this experience, I already plan to use Blue Lake Construction for more projects in the future, and I would confidently recommend them to anyone looking for reliable, honest, and high quality construction work. If youre looking for a contractor who actually shows up, delivers what they promise, and finishes on time, Blue Lake Construction is the real deal. Highly recommended. Moses"

"I want to share my experiance with Blue Lake Construction because Im honestly so happy I chose them. I had a big exterior project done on my house replacing old wood siding with Hardi board, building a new front porch, replacing the garage door, installing a new shingle roof, and upgrading all the windows to double pane energy code. It was a lot of work and I was nervous starting something this big. I got quotes from several other companies and every single one came in over 120k, which felt crazy and honestly discouraging. When I met Leo from Blue Lake Construction, he walked me through the whole scope in detail and gave me a price that actually made sense. Not cheap, but fair, and I never felt like they were trying to take advantage of me. The work itself was done the right way. The Hardi siding looks amazing, the porch completely changed the front of the house, and the new windows already made a big difference with insulation. The roof and garage door came out perfect too. The crew was profesional, showed up on time, and communication was always clear. What I appreciated most was how smooth the process was. Any questions or concerns I had were handled right away, and everything stayed on budget. Im super happy with the result and feel like I got real value for my money. If youre looking for a trustworthy contractor for exterior work, siding, roofing, or windows, I highly recomend Blue Lake Construction. They deliver quality work at a fair price and really care about the outcome"

"I'm from Kirkland and I want to share my experiance working with Blue Lake Construction on our master bathroom remodel. Me and my wife have been planning this bathroom for a long time and we interviewed multiple companies before choosing who to trust. Some bids came in crazy high, from 45k all the way to 75k, and honestly a few of them didnt even take the time to explain the process. Blue Lake Construction was different right from the start. Leo took us to the showroom to see materials in person and helped us build a clear, detailed scope of work so we knew exactly what were paying for. Their bid came at 40k which was already better than anything we got, but the biggest thing was the process the communication felt open, easy, and no stress. During the project, any worry we had was taken care of fast. We always knew what was happening each day, and the team really made the effort to get things right and make sure were happy. It was honestly really easy to deal with Leo and the rest of the crew. The final result is amazing: -stand-alone tub -double shower -double vanity -smart toilet install Everything came out clean, modern, and exactly the way we imagined it when we were designing it for months. Im super happy we chose Blue Lake Construction. Profesional, honest, and the best communication we had with any contractor we talked to. If youre in Kirkland or around and planning a remodel, I highly recomend them they really deliver what they promise."

"I want to share my experiance with Blue Lake Construction, because honestly they saved my whole project. Im 35 and was building an outdoor space in my house in Brier with an elevator for my mom, and also getting everything ready for my wedding this coming spring. I originally signed with another company but they struggled for months just trying to get the permit approved. It honestly stressed me out like crazy because the wedding date was getting closer and nothing was moving. I reached out to Leo at Blue Lake Construction and from the first meeting I felt like things finally going in the right direction. He took over the project, handled all the paperwork, resubmitted the plans under his company, and got the permit approved in like 3 weeks. No delays, no excuses. After that, the build started right away and they didnt fail even one inspection. The work itself came out incredible. Everything is built from Ipe wood, the highest quality you can get, and you can really see the difference. The deck, the stairs, the covered roof connection to the original roof, the lighting, the stain color it all came out perfect. The elevator is smooth and safe for my mom, and the whole outdoor space looks like something out of a luxury magazine. I was super stressed in the beginning but Leo and his team made the whole thing easy and profesional. They finished exactly when they promised and the result is better than I imagined. If you want top quality work and a contractor who actually gets things done, I realy recomend Blue Lake Construction. Thank you Leo for everything, I love it all."

"My name is Chuck from Sammamish and I want to share my experiance with Blue Lake Construction. I had them do exterior painting on my house in my favorite color, a light yellow, and the result came out perfect. They also fixed some wood on my deck and roof boards, painted the deck and the front landing everything was done clean and smooth, exactly the right way. Leo is a great project manager and will use him again when the opportunity presents itself. What I liked the most was the quality of the paint and the value I got for the price. When you look at the job they did and the material they used, its honestly the best deal out there. Leo was always in communication with us, explaining every step, and if we had any comments or small changes he took care of it right away without hesitation. The work came out so good that after the exterior was done, I signed two more contracts with Leo one for interior painting and another to replace the carpet in the whole house. That should tell you how happy I am with the results. Thank you Blue Lake Construction for the perfect results and for being so profesional and honest. I really recomend them to anyone in Sammamish looking for reliable painters and contractors that actually care about the work they do."
