Questions

Outdoor Living FAQs

How much does a paver patio cost in Northern Virginia?

Installed paver patios start at $35 per square foot, so most projects start around $9,500 — final price depends on size, material tier, and site prep. Complex grading, drainage, or premium stone push it higher. Every Lawn Theory estimate is a written, line-item quote in 24–48 hours — no upsells.

How much does it cost to build a deck?

Composite decking starts at $75 per square foot installed, so most decks start around $12,500 — final price depends on size, material, height, and built-in features like railings, benches, and lighting. We price transparently and explain the trade-offs of wood vs. composite vs. PVC.

Deck or patio — which is better for my backyard?

Patios are usually more budget-friendly, lower-maintenance, and longer-lasting, and they work best on level ground. Decks add elevated usable space and strong resale value, and they shine on sloped or raised lots. We help you choose based on your grade, how you want to use the space, and your budget — and we build both.

How much does an outdoor kitchen cost?

Outdoor kitchens start at $18,000, driven mostly by appliances, countertop material, and utility runs (gas, water, electric). A simple built-in grill station starts lower, while a full chef’s station with fridge, sink, and bar sits higher. We design to your budget and handle the hookups and permits.

Do patios and decks add value to my home?

Yes. Quality hardscaping and outdoor living space is one of the better returns in home improvement — often a 20–30% ROI or more — and it makes a home noticeably more appealing to Northern Virginia buyers who want ready-to-enjoy outdoor space.

How long do paver patios and decks last?

A properly-built paver patio can last 25–50-plus years, and individual pavers can be lifted and re-set if ever needed. Composite decks commonly last 25–30-plus years. The difference is the base: our engineered foundations are built for Virginia freeze–thaw, which is what prevents the heaving and sinking you see on cheaper builds.

Do I need a permit to build a deck or patio in Virginia?

Decks almost always require a permit in Northern Virginia, and many hardscape and structural projects do too. We are fully licensed and insured and handle permits, inspections, grading, and drainage for you — so the project is done right and to code.
