No. 7 Development is a first class company. Matt is a solid guy that sticks to his word. We had Matt and his crew do a build out in our office location and he got done earlier than planned and on budget. Two things that rarely happen these days. Their work is top of the line and I was really impressed with the final product. I would recommend No. 7 Development to anybody looking for a great builder. See more See less

Matt and his Crew at No. 7 Development were in a word "Awesome." They took two unsightly rooms and turned them into the most beautiful Spa-like bathroom with oversized tiled shower and towel dry-off area! Absolutely gorgeous, exactly what I dreamed of!! I would hire them again in a second! Oh, I already have. Can hardly wait for them to start our next project! JR Greene/Arlington See more See less

I hired Matt to finish a basement for me. He did all of it from start to finish. The attention to detail was excellent. He has years of experience in the trade so he was able to provide insight to improve upon my vision of what I wanted. This not only allowed for the rooms to be more functional but added more resale value in the end. I highly recommend Matt and his team for any of your building projects! See more See less

I have had the privilege of having remodeling work done by Number 7 Development. Matt and his crew are awesome. Not only did they do great work, on time and on budget, they handled most of the design work as well. Matt and his crew were professional from start to finish. I have had occasion to hire many contractors in my four decades of business, and Number 7 Development stands out at the top of the list of all General Contractors I have worked with. Pride, honesty, and integrity seem to be just marketing words by most, but Matt and his team are proof these values are still alive and well. Most Sincerely, Greg Pinneo Real Estate Entrepreneur See more See less
After living on Samish Island for almost 3 years, I have struggled to find good help with home projects. On Saturday, I got a leak in my garage from a nearby bathroom, so as I was working to find someone to fix that problem, I also contacted some contractors to do a much planned remodel of that bathroom since we had the leak anyway. Matt came out ON A SUNDAY to check out the potential remodel project and came back the next day on MONDAY NIGHT to stop the leak, he did this BEFORE any of the plumbers I had called even responded to me!! He was professional, compassionate, sincere and outstanding in this work ethic and attention to detail. I have cancelled all my other meetings with contractors for the bathroom remodel and am working with Matt exclusively. Call Matt, he's terrific and he really cares. See more See less
Matt and Kayla are a wonderful father/daughter team. They are always so responsive and do high quality work. Have worked with them twice now on two different projects and will absolutely retain them for any future projects! Highly recommend! See more See less
Matt was fantastic to work with! Honest, efficient, and trustworthy. Definitely working with him again if needed. Thank you!! See more See less
I called No 7 to complete a project and was happy I did. They not only kept to schedule and budget but they also were able to tackle another project that I had planned on completing at another date. Highly recommend will call for all of my contracting needs. See more See less
Matt and crew were amazing during our home remodeling...always attentive, sharing great ideas, with excellent planning and execution. They worked long hours to complete each phase/task and negotiated the complexity of permitting on the Island. As we plan each new phase of our remodeling adventure, Matt continues to be involved...even when we get into our DIY projects. His ideas and guidance are invaluable. We strongly recommend No 7 Development for any construction project! See more See less
I definitely recommend No. 7 Development. Matt and his crew were excellent to work with during the renovation process. Personable and extremely knowledgeable, Matt is an excellent craftsman. Everything was completed beyond my expectations! Thank you so much for a great job, outstanding quality, and professionalism. See more See less
Matt and the No 7 Development Team were absolutely amazing. Communication was open at all hours throughout the whole process, they were very punctual and professional and at the same time very friendly and understanding. Would definitely recommend them to anyone See more See less
These guys are great. They showed up at 9 every day and didn’t leave until dusk sometimes. Pricing is reasonable for the quality work they produce. Our house looks really good. All our neighbors have told us the same. They’re all friendly and really listen to the client. Couldn’t be any happier. See more See less
I contacted Matt in March 2021 about seeing if he was interested in constructing a deck off a 2nd floor ADU. He came and evaluated the job a couple days later (on a Saturday) and said that not only he could do it, but that it could be done in about 2 days and he could start the very next Saturday. We also agreed that because this was a small project it could be done between his other major jobs and might take a week or two to complete. I was skeptical and expected the typical "something came up, have to postpone/cancel" call, but he showed up bright and early on the following Saturday to start work just as promised. We discussed some modifications which improved the aesthetics of the deck and he got down to business. Two weeks later on a Saturday he showed up again bright and early, completed the deck and it has exceeded my expectations. I watched the entire process and asked many a question, and he had a thoughtful and professional answer for every one. I have carpenters and architects in my family so I probably know just enough to know what is quality work and what is not. Matt really builds beautiful and durable stuff. The planning dept inspector asked a few clarification questions and was very pleased with the structural integrity and how it was built. I have another project in the pipeline and I hope that I can recruit Matt to do that one for me. See more See less
I use No. 7 because they are great at communicating, getting contractors scheduled appropriately, easy to work with and the end product always is above and beyond! I’ll use them for all my projects! See more See less
Hired No. 7 to complete some repair work on the decks at my rental property. Matt was very easy to work with, did what he said he would do, communicated well and completed the work efficiently. I also thought his pricing was fair. I plan on hiring him again in the future and would recommend. See more See less
Matt’s quality of construction are matched by his professionalism and honesty. Anyone having a home built by him would be very fortunate. See more See less
Matt and Kayla were delightful to work with and were very responsive. Matt and his crew did high quality work on our Kitchen remodel. All of Matts crew were professional and courteous, and at the end of a work day, cleaned everything up very well. I can recommend them highly. See more See less
Matt from No 7 Development is very professional and easy to work with. I highly recommend them! See more See less
I hired Matt and his team to help frame my new dream home. When my foundation crew skipped town and left me in a bind, Matt jumped in and saved the day. In an area where construction seems more like the wild west where there is no quality control or repercussions for people who have no business in construction, Matt is a rare find. He is trustworthy, honest, and hard-working, qualities that are definitely hard to come by in construction in Seattle these days. If you are in need of work to be done, I would not hesitate to call Matt and his crew. See more See less
No 7 Development did a wonderful job installing our SIP roof panels. Our job site was narrow and cluttered, but Matt and his crew executed well without gripe or complaint. Great communication and friendly service. See more See less
Matt and his team did an excellent job remodeling our guest bathroom! From the onset they were quick to respond to my inquiry and were able to fit our project into their existing schedule. The work they performed was very high quality. We are very pleased with the whole experience and love the end result! See more See less
No 7 Development is fantastic to work with! Matt is approachable, responsive and made the overall experience of scheduling work to be done at my house enjoyable and stress free. I am fairly new to the area and I reached out to 8 contractors and builders for a small job - and Matt immediately got back to me. He communicated with me quickly and was clear to about availability and estimates. He worked within my schedule - and helped with demolition, prep and installation of a project for my kitchen. I have been highly satisfied with No 7 Development - and I will continue to use Matt and his company going forward. I would highly recommend anyone contact No 7 Development for professional and reasonable projects. See more See less
