We design and build outdoor spaces that perfectly match your vision and your home’s style. The process starts with a simple conversation where we learn about what you’re looking for. From there, our skilled custom deck builders handle everything from the design to the final installation. We focus on making the entire experience smooth and enjoyable, delivering a finished deck that you will love for years to come.
We believe that the best decks designed are the ones that fit your life perfectly. Whether you need a large, multi-level deck for hosting parties or a small, intimate space for quiet mornings, we can create it for you. We listen to your ideas and provide expert recommendations to ensure the final layout is both practical and beautiful.
Our professional custom deck services are built on a foundation of trust and quality. We pay close attention to detail in every step of the process, from securing the foundation to placing the final board. This commitment to excellence ensures your deck is not only stunning but also safe and durable, ready for years of enjoyment.
We offer a wide range of custom decking materials to suit your preferences and budget. This includes beautiful wood options and high-performance composite decking, which offers durability and low maintenance. We’ll help you choose the best material that complements your home and can withstand the elements, ensuring a long-lasting investment.
We provide a comprehensive structural evaluation to determine if your existing frame is “level-one” ready for an upgrade. If your foundation is sound, we can perform a professional resurfacing—replacing worn-out wood with premium Trex or TimberTech composite—giving you a brand-new look at a fraction of the cost. However, if we find signs of rot or structural instability, a full deck replacement is recommended to ensure your home’s safety and long-term value.
Hiring a Trex Pro Platinum installer means you are working with a contractor at the highest level of manufacturer certification. This elite status allows us to offer industry-leading warranties on materials and labor that standard contractors cannot provide. For Seacoast homeowners, this ensures your deck is engineered with the latest heat-mitigating technology and moisture resistance, essential for surviving New Hampshire’s diverse climate.
Yes, a primary unique selling proposition of our company is that we handle all local permitting and inspections for our customers. We have deep experience navigating the building codes in Nottingham, Epping, Exeter, and throughout the Seacoast, saving you the stress of paperwork and ensuring your project is 100% compliant with local regulations.
While wood offers a classic look, homeowners in New Hampshire often grow tired of the constant sanding, staining, and rot issues associated with the Seacoast’s humidity. Composite decking from Trex, AZEK, or TimberTech is virtually maintenance-free, splinter-free, and resistant to fading and mold. It is the ideal choice for those seeking “low-maintenance luxury” and a higher return on investment for their property.
Absolutely. While we are known for our custom decks, we specialize in high-ticket exterior additions including 3-4 season rooms, pergolas, and Additional Dwelling Units (ADUs). These larger projects range from $50,000 to over $150,000 and are designed to provide “square feet under your feet” for year-round enjoyment. Our 3rd-generation framing expertise ensures these additions blend seamlessly with your home’s original architecture.

The craftsmanship on our front entry stairs is top-notch and exactly what we wanted! Allan and team really take pride in their work and the project went smoothly from start to finish. Very happy with the result.Posted on Alexandra RoyTrustindex verifies that the original source of the review is Google. Can’t say enough good things about working with Allan & his team. The whole process was easy, transparent and professional. Hired them to do some work that impacted the inside and outside of a second floor window. After we contacted them they made it easy to schedule a time to meet and get a quote, understand costs, answered all my questions. They were very knowledgeable about what they were doing and how they would repair the problem. We trusted them to do the job and they did not disappoint! The team that came to do the job was well mannered and cleaned up after themselves. I can’t say I’ve ever worked with a contractor that was this put together. We recommend them and will also be using them again for future projects.Posted on Stephen MyongTrustindex verifies that the original source of the review is Google.
