Here are just a few.



I recently had the pleasure of using Northern Deckworks for my screened-in deck and patio project. Tim created accurate and aesthetically pleasing plans and the construction team executed them beautifully. Tim was communicative, easy to get a hold of, and provided the appropriate paperwork for our HOA, which made the project move along smoothly. Further, the project estimate was accurate and there were no budget overages. During construction, the carpentry team demonstrated a high level of professionalism and expertise. The quality of workmanship was exceptional. The deck was built with precision and care, and it is clear that this team has an efficient system for working together. We were able to see progress quickly and their attention to detail and craftsmanship exceeded my expectations. I highly recommend Northern Deckworks to anyone looking for a top-notch, reliable, and skilled team to bring their outdoor space dreams to life. The combination of professionalism, craftsmanship, and customer-centric approach makes Northern Deckworks stand out in the industry. I am thrilled with my new deck and patio.

We replaced our 30 year old wooden deck with a new, safe, code compliant wooden deck this summer. After reviewing several estimates, Northern Deck Works was the clear winner. Plus, I could see their quality craftsmanship every day, since they built our backyard neighbor's deck the year before. Our neighbor wholeheartedly recommend Northern Deck Works, but I got other estimates to check pricing. Northern Deck Works wins!

Easy to work with and Tim listened to what we wanted with a new deck design. I took care of HOA and Tim handled County permits. The work crew deserves six stars! They are superb craftsmen, hard workers, and clearly enjoy their work. Demolition and construction took about a week, the site was cleaned up nicely, and we started to show off our new deck to family and other neighbors! 100% satisfied.

We could not be more pleased with the screen porch Tim O’Neill designed and his Northern Deckworks team, led by John, built.  Both functional and beautiful, Tim’s design is perfect for us.  We opted for the EZ Breeze window system and a gas fireplace.  This will enable us to enjoy our porch nearly year-round.  As part of the project, we also replaced our front walkway and steps and back steps and patio with flagstones. Tim and the masonry crew solved a drainage problem that had plagued us for years. 

From the outset, Tim and John kept us updated on the status of our job, permits, when deliveries would occur, when the crew would be on site, etc.  The crew was respectful of our property, and the job site was clean every day when they left. 

From the plans all the way through the final product, Tim insisted on quality – of materials and construction – and attention to detail.  The result is very aesthetically pleasing.  Everyone who’s seen the porch has commented on how it’s so much more than “just a porch.” 

Tim’s artistic design has become a wonderful reality. We look forward to enjoying our Northern Deckworks porch for many years.



Tim and his Northern Deckworks team did a fantastic job in building our mahogany and cedar screen in porch and deck. The craftsmanship is top notch. We really like the EZ-Breeze window system. All you need to do is either slide the window down or up for great air flow. The screen keep all the bugs out. Our first appointment, Tim came by the house, took measurements and drew
the plans up. Tim was in regular communication with us during Covid, responded promptly to text and calls. Inform us the status of the built permits. During the initial built the crew came by 6 days a week, work long hours and they cleaned up nicely at the end of each day. The crew were always clear in advance if they would miss a day or two because they were awaiting for materials due to supply issues. Tim stay in contact during the duration of the project, informing us of any changes that came up as well as any delivery to the house. We highly recommend Northern Deckworks.

A gorgeous craftsman built oasis at home. Tim and his Northern Deckworks crew, led by John, built us an absolute artisan masterpiece of a screened porch that is the envy of our neighbors and a delight to us. Built from the finest materials and woods available and molded by the capable hands of John and his crew, this screened porch is shockingly gorgeous and highly functional, particularly with the addition of the EZ-Breeze window system.
Tim recommended Patty and Jeff to finish the mahogany floors, cedar walls, and railings (you can find their contact information on Tim's website). Like John and his build crew, Patty and Jeff are highly skilled, professional and meticulous. The mark of an excellent contractor / project manager is in the people they hire and recommend. On all counts with John and his crew, Patty and Jeff, Tim is an excellent contractor and project manager.
We are delighted with our Northern Deckworks screened porch and highly recommend you choose Tim and his folks for yours.

Northern Deck Works constructed my porch with the highest level of expertise and care. Tom O'Neil and the team at Northern Deck Works are true craftsman that only use the best products (cedar, mahogany etc) to custom build a porch that puts others to shame! The attention to every detail, the precision, the hand crafted touches are unbelievable. This project has made our house a home. We use it even when the temperature is 21 degrees! We crank up the gas fireplace and enjoy 70 plus temps in the room! Year round use with Eze Breeze windows ensures a sealed in experience even during harsh weather!

Working with Tim and the his team (Juan and Darwin) has been a pleasure! He cares....truly cares about the finish and fit of every project. It is not a dollar sign to Tim. He and his team put their life and spirit into these porches. Tim is very responsive to changes and feedback. He cares about the product and the joy it delivers to his customers. Works of art don't develop fast- keep this in mind. Building porches like this is an art and takes time. "Do it right the first time", I am certain, is their undisclosed motto.

My family can't thank Tim, Juan and Darwin enough for the timeless joy that they have given us by building a room where countless historical events will occur. Thank you all for your dedication to excellence and attention to detail. True professionals. True craftsman. Unimaginable porches! You can't go wrong with Tim and his team if you want top-notch construction.

If you are looking for an exceptional screened porch for your home, please take the time to meet with Tim O’Neil from Northern Deckworks. Our porch was built with cedar and mahogany materials and truly exudes quality craftsmanship that far surpasses other contractors. Tim has exceptional crews that ensure great attention to detail, compliance to all standards and codes. He also partners with the very best electricians, masons, and even outdoor fireplace and furniture stores. He has built 20-year relationships with both his employees and even a team who can finish and stain your porch to guarantee it remains beautiful for the years to come. Tim’s artistic eye helped take our design of a screened porch with a flagstone patio and a blue stone retaining wall from a dream to reality. We would highly recommend the outdoor window option, which turns your porch into almost a four-season room. Your project will be managed from start to finish by one point of contact; eliminating any subcontracting hassles. Despite it being winter season, our project was finished on time and within budget. Post pandemic we look forward to sharing our new porch with our family and friends. Thankful we took the time to find Northern Deckworks and experience the quality difference.

We've spent our first year with our covered porch built by Tim O'Neill and his expert crew led by John. The EZ Breeze windows have been a plus. This mild winter provided us with many days of extra enjoyment as we sat outside with a little help from a heater. We are so glad we listened to Tim's suggestion to make the space bigger than we originally thought we wanted. It's our favorite place to relax and enjoy the nature surrounding our home.

After looking into various companies we selected Northern Deckworks. Tim and his crew quickly removed our old deck and built a gorgeous new deck much quicker than the deadline we had agreed to. We would highly recommend Northern Deckworks to anyone looking for a new deck.

We looked at numerous screened porches before we selected Northern Deckworks. What impressed was not only the quality and design, but how good the porches they built ten or more years ago still look. Our porch absolutely surpassed our expectations. When you select a contractor, you do your research, check references, and then pray it goes well. Tim O'Neill and his workers were the answer to our prayers. They take pride in their work and it shows. We couldn't be more pleased.

Our new porch backs up to a community pathway and not a week goes by that someone gives us a comment on the beautiful appearance of our porch. We were very fortunate in our research to find Northern Deckworks. From the time that Tim O'Neill sat down with us to design, give us the price and throughout the completion, he has always been available. He is responsive and customer satisfaction is one of his top priorities. The quality of work, materials and design surpassed our expectations.

Northern Deckworks came highly recommended by two of our neighbors. We were able to see the high quality of their work and they did a fantastic job on our home. Tim and John worked to transform our limited backyard space into a great place to relax, entertain, and enjoy. Tim worked with us not only on the deck plans (with mahogany and cedar plus Eze-breeze window upgrades) but did a super job of integrating a large flagstone patio under the deck, plus building an adjacent fire pit. John is, by far, the most talented carpenter craftsmen in this area. We are 100+% satisfied and highly recommend them.

I had seen Northern Deckwork's screened porches on our street and inour neighborhood and was impressed with the workmanship. I met Tim and we knocked out a design that include a 20x16 screened porch, exterior deck, four season room in place of my old screened porch, and a shed under the new porch. I couldn't be happier with the final product; the screened in porch is my favorite room in the summer and my four season room is my favorite room in the winter. I would definitely use Tim again.

The devil is always in the details and Northern Deckworks gets the details right the first time. From start to finish, this was a painless experience - Tim helped us design our deck and suggested additions that we hadn't even considered such as angling one side of the upper deck to better fit our terrain. His crew arrived promptly early each morning (weather permitting) and worked until after dark for 10 days to build our 635 sqft, two level deck. We are very pleased with the result.

You will not find a better quality product anywhere! Tim and his crew built a masterpiece. we ABSOLUTELY LOVE our porch, deck, and spa cedar privacy wall and trellis. The craftsmanship is unmatched. Tims crew meticulously sanded and stained all rafters before they were ever installed! This led to a perfect blend of cedar and high quality yellow pine ceiling that looks spectacular. The edge work detail on all of the wood is amazing. Time only uses the highest grade treated pine and cedar!

We absolutely love our beautiful new porch, patio, and firepit - thanks to Northern Deckworks. Tim (owner) sat down with us and explained the process and prices. Throughtout the process when a question came up, he was very willing to discuss the issue. His crew was prompt, worked hard, and polite. They answered questions when we had them too. Weve had a follow up issue and Tim sent his crew back to help out with it in a very timely manner. We have suggested NDW to our friends!

We cannot say enough great things about the amazing screened in porch and deck Tim built for us. He is a professional who is not satisfied until the finished product meets his high standards. Without reservation, I highly recommend any prospective client ro work with Tim. Additionally Tim recommends Patty Dennis of metropolitan Deck Finishers to stain and protect the deck. We hired Patty and absolutely love the result. Her quality and attention to detail are a perfect complement to Tim.

I recently had a screened in porch built by Northern Deckworks during February and March. Despite the questionable weather conditions the project was finished in a timely manner and the end result did not only meet my expectations it TOTALLY EXCEEDED them. It is a beautifully designed outdoor room. The two man crew that built the porch were firndly and courteous and kept the project area neat. The carpentry is flawless and the ocst was 40% less than two other estimates I received!

Hired Tim to build a screen porch and couldn't be happier. The combination of his design experience and the quality of his crew was exceptional. The craftsmanship is second to none. The porch is the focal point of our home. Way to go Northern Deck Works!

I originally hired Tim O'Neill and Northern Deckworks about 16 years ago to teardown my little deck and build a large deck, with a screened in porch, built-in benches and a surround for my hot tub. We loved the deck and used it often. 16 years later the deck still looked great. However it was time to remove the privacy fence and the hottub. I only called one deck company. Tim came out, replaced all the decking, plus built a beautiful flagstone patio. Northern Deckworks is the best in decks.

The work was just completed on our new deck and porch by Northern Deckworks and we couldn't be happier with the results, and the whole process in general. Tim came out, took measurements and drew the plans up right there. He also stayed in contact during the duration of the project, informing us of any changes or anomalies that came up. The work itself is fantastic. John and Charlie were great; they came every day, even in the rain, were polite, neat, informative when we asked questions and worked hard. They even took the time to engage my young kids who loved watching them work. Everyone who has seen the finished results say it's beautiful. I would highly recommend Tim and his crew!
