Allan Trant Exteriors, founded in 2014, is built on a legacy of craftsmanship spanning three generations. Allan Trant, a third-generation carpenter, grew up immersed in the art of construction. He learned the values of precision, hard work, and customer-first service from a young age. Today, his team specializes in creating high-quality decks and outdoor living spaces, delivering projects that reflect integrity and lasting value.
More than just a builder, Allan Trant Exteriors prioritizes personalized service and honest craftsmanship. From using premium materials to ensuring clear communication and timely project completion, we are committed to turning homeowners’ visions into reality. With a foundation of integrity and community commitment, our team creates spaces that homeowners can cherish for years to come.
We understand that a new deck is a significant addition to your home, which is why we provide a robust deck building warranty to protect your project.

This approach covers the labor and the materials used in your project.
MAKE YOUR OUTDOOR LIVING PROJECT AFFORDABLE WITH GREENSKY®
Investing in a custom composite deck, home addition, or outdoor living space shouldn’t mean compromising on quality or waiting years to build. At Allan Trant’s Exterior Finish Work, we partner with GreenSky® to offer flexible, hassle-free payment solutions tailored to fit your budget.
Through our dedicated GreenSky financing options, New Hampshire homeowners can take advantage of fast approvals, competitive rates, and deferred interest or low monthly payment plans. Whether you are planning a complete deck resurfacing, an ADU build, or a luxury outdoor kitchen, you can start construction today while managing payments comfortably over time.
Applying is quick, secure, and will not impact your credit score during initial pre-qualification. Contact our team today or visit our financing page to learn more about funding your upcoming project.
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 and 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.
Choosing Allan Trant’s Exterior Finish for your custom decks means you’re partnering with a team that is passionate about quality. With generations of carpentry experience, we bring a high level of skill to every project. We are committed to your satisfaction and work diligently to create an outdoor space that exceeds your expectations and enhances your home.
