Deck Building
If you’re planning a new deck, the most important decisions happen before any boards go down. How you’ll use the space, where the sun falls, how the deck ties into the house, and how you move between the deck and the yard all shape the design.
A new deck project generally involves several planning areas:
- Layout and size based on how you’ll use the space and how it relates to doors, windows, and sightlines
- Framing and footings sized for the span and set to local frost-depth requirements
- Ledger attachment and flashing where the deck connects to the house, to keep water out of the structure
- Decking material selected for appearance, maintenance, and budget
- Railings and stairs that meet code and suit the site
- Permits and inspection coordinated with the authority having jurisdiction
Deck Replacement
Older decks fail in predictable ways. Boards soften, fasteners rust, railings loosen, and the ledger connection to the house can deteriorate where water has gotten in.
Common things worth checking include:
- Soft, cupped, or splitting deck boards
- Loose or wobbly railings and guardrails
- Corroded fasteners, joist hangers, or connectors
- Signs of water damage at the ledger where the deck meets the house
- Footings or posts that have shifted or settled
Choosing Deck Materials
Each deck materials involves tradeoffs in cost, maintenance, and appearance:
- Pressure-treated lumber: is the most economical option and widely used, but needs periodic cleaning and sealing.
- Composite and PVC: cost more up front and require less routine upkeep, with a range of colors and textures.
- Hardwoods: offer a distinct look and durability at a higher price point, with their own maintenance needs.

How do I know whether to repair or replace my deck?
It depends on overall condition, not age alone. A deck with a few worn boards but sound framing and footings may only need resurfacing or board replacement. Widespread issues point toward a full replacement: soft or rotted framing, corroded joist hangers and connectors, a deteriorated ledger where the deck attaches to the house, or posts and footings that have shifted. JLG Builds inspects the structure and explains what we find before recommending a scope.
What decking materials can I choose from?
The common options each involve tradeoffs. Pressure-treated lumber is the most economical but needs periodic cleaning and sealing. Composite and PVC cost more up front and require less routine maintenance, with a range of colors and textures. Hardwoods offer a distinct look and durability at a higher price point. We help you weigh appearance, budget, and how much upkeep you want before selecting a product.
Do I need a permit to build or replace a deck in Maryland?
Most new deck construction and many replacements require a permit, and requirements vary by county and municipality. The authority having jurisdiction sets the rules and determines approval. JLG Builds can identify the permits typically required for your project scope and coordinate applications and inspections when that work is included in the contract.
How much does a new or replacement deck cost?
Deck pricing varies widely and there is no single figure. Size, height above grade, framing complexity, material selection, railing and stair design, footing requirements, and existing conditions on a replacement all affect the total. JLG Builds provides a project-specific estimate after reviewing the site and settling on materials.
How long does a deck project take?
Timing depends on the design, scope, material lead times, permit timelines, weather, and any hidden conditions found during a replacement. Rather than quote a fixed duration, JLG Builds provides a project-specific schedule once the scope and major selections are established.
