Your outdoor space should feel like a natural extension of your home — a place to relax, entertain, and enjoy every season. At Affinity Building Solutions, we specialize in custom deck building, delivering durable, high-quality outdoor spaces designed for real-life use.
Whether you’re looking for a brand-new deck, replacing an aging structure, or upgrading to a modern outdoor living area, our team handles everything from design to final construction. We combine expert craftsmanship, premium materials, and a streamlined process to ensure your deck not only looks great but lasts for years.
Every home is different — and your deck should be too. We design and build custom decks tailored to your property, lifestyle, and budget.
Our deck building services include:
• New deck construction
• Custom outdoor living spaces
• Deck extensions and upgrades
• Integrated seating, lighting, and features
We focus on creating functional, visually appealing decks that enhance both your home’s value and your day-to-day living experience.
We offer a wide range of deck styles and materials to match your needs and preferences.
Low-maintenance, long-lasting, and resistant to weather damage. Composite decking is ideal for homeowners who want durability without constant upkeep.
Classic and natural, wood decks provide timeless appeal and can be customized with different finishes and designs.
Extend your outdoor living season with a covered deck that provides shade and protection from the elements.
Perfect for sloped yards or large spaces, multi-level decks create defined areas for relaxing, dining, and entertaining.
If your existing deck is showing signs of wear, damage, or structural issues, we provide professional repair and replacement services.
Common issues we fix:
→ Rotting or weakened wood
→ Loose railings or unstable framing
→ Outdated or unsafe designs
→ Weather damage and surface wear
If repairs are no longer cost-effective, we can recommend a full replacement that improves both safety and aesthetics.
Not every deck needs a full rebuild. In many cases, a professional refresh service can restore the look, safety, and performance of your existing structure without the cost of starting from scratch.
At Affinity Building Solutions, our Refresh Decks system focuses on upgrading the visible and functional parts of your deck while preserving the existing structural frame when it is still safe and sound.
Refreshing a deck refers to improving and restoring an existing deck through resurfacing, refinishing, or selective replacement — without a complete structural rebuild.
This approach is ideal for homeowners who want to modernize their outdoor space while saving time and cost.
We replace worn-out deck boards, railings, and stairs with new, high-quality materials such as composite or upgraded wood — while keeping the existing framing intact.
This is a popular option for converting older wood decks into modern, low-maintenance outdoor living spaces.
For decks that are structurally sound but weathered, we provide cleaning, sanding, staining, and sealing to restore their appearance and protect against future damage.
A refresh is ideal when:
➢ The structural frame (joists and beams) is still strong
➢Surface boards are worn, faded, or damaged
➢ You want a visual upgrade without full replacement
➢ More cost-effective than full rebuild
➢ Faster project completion
➢ Extends the life of your existing deck
➢ Improves appearance and usability
➢ Option to upgrade to composite materials
