How We Build Your Deck

Consultation & Design

We start by understanding how you want to use your deck. Is it for grilling? Hosting family? Creating privacy? We'll sketch out the layout, discuss materials, and review your wish list.

Accurate Quotes & Timelines

Once we understand your needs, we provide a transparent quote that includes labor, materials, and timeline. No hidden fees — just straightforward information to help you plan.

Material Selection

From classic pressure-treated lumber to ultra-durable composite decking, we offer options that suit your style and maintenance preferences. We also provide railing, stair, and lighting choices.

Permit Handling

Decks require permits in many parts of New Jersey. We’ll take care of the paperwork so you don’t have to worry — making sure everything is up to code.

Expert Construction

Our team builds to last. Every cut is precise, every board leveled, and every fastener placed for long-term performance. We work clean, respect your property, and stick to schedule.

Final Walkthrough

Before we wrap, we walk through every part of the deck with you. If something isn’t perfect, we’ll make it right. Your satisfaction is our top priority.

Frequently Asked Questions – Decks

What materials do you use for decks?

We offer both wood (pressure-treated pine, cedar) and composite options (Trex, TimberTech, etc.). Composite is a popular low-maintenance choice that resists fading, splintering, and insects.

How long does it take to build a deck?

Most decks are completed within one to two weeks after materials are delivered and permits approved. Complex designs may take longer, but we’ll give you a clear timeline before we begin.

Do I need a permit to build a deck in NJ?

Yes, in most municipalities a permit is required. K&H handles all permitting to ensure your deck is 100% up to code and approved by local authorities.

Can you rebuild or expand an existing deck?

Absolutely. We can tear down old decks, expand layouts, or upgrade your current deck with new materials, railings, and steps.

What’s the lifespan of a typical deck?

Wood decks can last 10–15 years with proper care. Composite decks often last 25–30 years with minimal maintenance. We’ll help you choose the right material for your goals.
