What We Do: Our Services to Upgrade Your Home
We design and build decks that make outdoor living effortless. Whether you’re dreaming of a space to host summer dinners or relax with ocean views, our deck installation services offer tailored solutions for every home.
Custom Decks & Deck Construction
As a trusted deck contractor in Portsmouth, we build custom decks that fit your space and the way you live. From multi-level layouts to swim/spa and rooftop decks, we tailor each design to make the most of your property. Our team handles everything from structural framing to finish work with care and precision, delivering a deck that’s ready for New England weather. Whether you want a spacious gathering spot or a quiet retreat, we build it right down to the last fastener.
Decking Materials: Composite and Wood Options
We offer both composite and natural wood decking to suit your home’s style and your maintenance preferences. For a traditional look, we install cedar and mahogany decks that bring natural warmth to outdoor spaces. If you prefer low-maintenance durability, we recommend composite options from Trex, TimberTech, Deckorators, or Fiberon. These materials resist moisture, fading, and wear—ideal for the New Hampshire climate.
Patios and Outdoor Living Structures Designed for Relaxation and Style
We design and build outdoor structures that expand how you enjoy your home. As a porch contractor, pergola builder, and gazebo builder, we create custom spaces that offer shade, comfort, and year-round use. Whether you’re looking for a screened-in porch, a three-season sunroom, or a fully insulated four-season room, we tailor each project to your lifestyle. We also install patios, outdoor kitchens, BBQ decks, and shower enclosures that blend function with style. Each structure is built with durable materials and designed to complement your existing space.
Deck Remodeling and Resurfacing Services
If your deck is showing signs of wear or no longer meets your needs, our deck remodeling services can bring it back to life. We handle structural repairs, surface upgrades, and layout changes to improve both safety and appearance. For homeowners looking to update their deck without a full rebuild, our deck resurfacing services are a cost-effective way to refresh the surface using new boards, while preserving the existing frame when possible. Whether you’re updating aging wood or switching to composite, we make the process smooth and hassle-free.
Custom Deck Features That Add Comfort and Function
We offer a full range of deck features to increase safety, comfort, and enjoyment. Our deck railing installation options include wood, metal, and cable styles that secure your space while complementing the design. For added visibility and nighttime use, we provide deck lighting installation with recessed lights, post caps, and stair illumination. Firepits and fireplaces create a natural gathering spot, extending the outdoor season. We also install dry space systems, bar top railings, and other details that turn a standard deck into your favorite place to relax.
Home Exterior Services for Lasting Curb Appeal
In addition to decks and outdoor living projects, we offer exterior upgrades that enhance both the appearance and efficiency of your home. Our siding installation services use durable materials that protect against moisture and require less maintenance. We also install energy-efficient windows that enhance natural light and help manage heating and cooling costs. For a polished finish, we offer custom exterior trim that highlights your home’s architectural style while adding an extra layer of weather protection.
