A Custom Deck That Fits Your Home
Room for a large dining table. A separate place to relax. Stairs that connect your deck to the yard more naturally. The right layout starts with how you want to use the space.
We’ll help you work through the layout, materials, and details, including:
• Multi-level decks and custom stairs to connect different areas of your outdoor space.
• Aluminum or cable railings to complement the deck and your preferred look.
• Porches and pergolas to extend your outdoor living options.
• Deck lighting for the spaces you want to enjoy after sunset.
• Under-deck drainage to help make the area below an elevated deck more usable.
Whether you have a clear plan or a folder full of ideas, we’d love to hear what you’re considering.
Composite, PVC & Wood Decking
Your material choice affects the look of your deck, its upkeep, and the overall project budget.
• Composite decking: An option for homeowners who want to reduce the regular staining or sealing associated with wood.
• PVC decking: Another option for reducing finishing upkeep, with different products to compare for appearance, specifications, and cost.
• Wood decking: A natural wood surface, including pressure-treated options, with ongoing care and finishing needs to consider.
Low maintenance still means some maintenance. Cleaning and care depend on the specific product you choose. We’ll discuss those requirements alongside the colors, finishes, and railing options that suit your home.
Deck Replacement & Repair
If your current deck no longer fits your needs, we can discuss a replacement, a different layout, or updated decking and railings. Leo’s also handles deck repairs.
The right scope depends on the condition of the existing deck and what you’d like to change. We’ll review those details before recommending the next step.
Quality, Not Quantity.
A custom deck involves more than choosing boards and railings. The layout, stairs, material choices, and connections to your home all need to work together.
Leo’s brings its own crew and trusted specialty subcontractors to the project. We want you to understand what’s included, feel comfortable asking questions, and know who to contact as the work moves forward.
Our interior and exterior remodeling experience also helps when a deck project includes other improvements to your home.
Our projects include a one-year limited workmanship warranty. See the warranty for coverage, exclusions, and how to request service.

Questions Before You Get Started
What affects the price of a custom deck?
Size, height, layout, material selections, stairs, railings, site conditions, and added features all affect the scope. For replacements, the condition of the existing deck matters too. Your free estimate will be based on your project rather than a single price applied to every deck.
Can I contact you before I’ve settled on a layout or materials?
Yes. Share what you have in mind, even if you’re still comparing ideas. We’ll discuss your goals and the information needed to put together an estimate.
What happens after I request an estimate?
We’ll follow up to discuss your project and the next step toward an estimate. Sending a few details about the space and what you’d like to change gives us a useful starting point.
