Real numbers for real Maryland decks.
Most contractors won’t put prices on their website. The reason is simple: a number on a page is a commitment, and most contractors don’t want to commit until they’ve had a chance to read the customer in person.
KP works differently. The prices below come from decks we’ve actually built across Charles, Prince George’s, and St. Mary’s counties. They’re tied to real sizes, real materials, and real county requirements. If your project looks like one of these, it’ll cost about what these cost. If it doesn’t, the consultation is where we figure out why.
No bait pricing. No mystery quotes. Just the math, the way it actually works.

Every KP deck starts with the same foundation. Madison Lumber premium ground-contact framing that shows up to your house straight, dry, and dimensionally stable instead of the wet, lower quality lumber most contractors install. Capped composite decking with a real warranty. Real railings, properly installed. Footings that meet Maryland code without shortcuts. Whether you’re building a small deck off the back door or a showcase build that anchors the whole back of the house, the bones underneath are the same.
What changes between the three tiers below isn’t the quality of what’s hidden — it’s the time and design that goes into what you see. Craftsman is built for the homeowner who needs a clean, well-built deck on a predictable schedule. Artisan is for the homeowner who wants stair lights and a couple aesthetic upgrades to the undercarriage that KP would put on every deck if cost was not a factor. Legacy is for the homeowner whose deck is going to be the thing people notice when they pull into the driveway.
Most KP customers land on Craftsman, and most of them tell us later they’re glad they did. It has been our signature deck for many years. Read each tier with that in mind, and find the one that fits your house, your family, and the way you actually plan to use this deck.
The production tier. Built clean, built fast, built to the same standard as everything else KP makes.
You came here with a budget that needs to stay where it is. Craftsman is the tier built for you — and we mean that. It’s not a stripped-down version of a better deck. It’s the same Madison Lumber framing, the same structural standards, the same crews you’d get on any KP build. What it doesn’t have is the upgrade package KP would put on every deck if the market allowed: PVC-wrapped beams, vinyl-wrapped posts, and recessed step lighting. We hold those out of Craftsman because including them would push the base price out of reach for the homeowners who genuinely need a tier at this level — and we’d rather build you an honest deck than lose you to a contractor who’d cut corners on framing.
Craftsman uses Fiberon Good Life Weekender composite decking with a 30-year warranty. Vinyl railings with black balusters as standard, backed by a 25-year warranty. Clean rectangular layout. The upgrades available here are the ones that don’t slow the build down — decking upgrades, post cap lights, skirting underneath. Curves, picture-framing, aluminum railings, and PVC wraps aren’t on the menu at this tier. They’re not technically harder to do; they take more crew-time, and that crew-time is what the next tier is built around. Craftsman exists because some homeowners need a fair price on a real, high quality deck, and KP’s job is to deliver that without pretending it’s something it isn’t.
You’ll get a clean deck, on a predictable schedule, built by a crew that takes the same pride in a Craftsman build as they do in any other.
Best for ground-level and single-story decks, and homeowners who want the KP standard at the most accessible price.
The custom tier. Where the upgrades KP would put on every deck come standard, and the deck starts looking cleaner on the undercarriage.
This is the deck most KP customers tell us, after the fact, that they’re glad they bought the upgrades. Not because it’s fancier — because the upgrades that come standard at this tier are the ones that actually mattered to them. PVC wraps protect the structural posts and beams from twenty years of Maryland sun and weather. Recessed step lights turn the deck from a place you use until 8 PM into one you use until October. Vinyl-wrapped posts make the deck look finished from the yard, not just from above.
Artisan starts with everything Craftsman includes — same Fiberon decking, same vinyl railings, same Madison Lumber framing — and adds the wraps-and-lights bundle as standard. The reason it’s bundled instead of sold à la carte is simple: buying these three upgrades separately on a Craftsman deck costs more than buying them packaged as Artisan. If you want them, this is the cheaper way to get them.
Artisan is also where the design conversation opens up. Aluminum railings, picture-framed deck boards, decking upgrades, and hardwired post-cap lighting as a coordinated system all become available at this tier. So does KP’s signature curve — a smooth cantilevered front bow, roughly 16 inches across a 30-foot span, that turns a rectangular deck into something that reads as designed without taking the build out of production territory. Anything more dramatic — tighter radius arcs, multi-segment curves, full custom geometry — is where Legacy starts.
If you’re elevating a deck off the back of the house, planning to host on it, and want it to look like something you’re proud to show off when the neighbors come over, Artisan is the tier we’d point you toward.
Best for elevated decks where the view from below matters, mid-size to large footprints, and homeowners who want the upgrades that turn a clean deck into one that looks designed.
The architecture tier. Where the deck stops being a product and starts being a design conversation.
Some homeowners come to KP with a clear picture in their head — a deck that wraps the back of the house, sits two stories above a walkout basement, and changes the way the whole property feels from the yard. If that’s the deck you’re imagining, Legacy is where the conversation starts.
Legacy isn’t Artisan with more boxes checked. It’s a different kind of project. The conversation begins with what you want the deck to be — how it sits on the house, how the structure underneath reads from the yard, how the lighting works as a system after dark, how the deck integrates with whatever else is happening in the back of the property. From there, KP designs the deck around your house, not the other way around.
What comes standard on Legacy and isn’t available on Artisan at any price: glulam beams that reduce post count and open up the view from below, architectural columns that replace standard wrapped posts, designer railing systems, and shop drawings that document the build as a designed structure rather than a standard layout. Premium PVC decking comes standard. Curves beyond the Artisan signature — tighter radii, multi-segment arcs, full custom geometry — become possible because the structural design is being engineered for your specific build.
Legacy decks take longer to build than Craftsman or Artisan. They’re priced as projects, not packages, and we won’t quote one without sitting down with you to understand what you actually want. If you’re building a deck that’s meant to be the centerpiece of the back of your house for the next twenty years, this is the conversation we’d have together.
Best for large outdoor living programs, second-story builds with prominent sightlines, and homeowners building a deck where the design itself is the point.
