Mitchell and his dad were great to work with. He was very reasonable with his quotes. They did a 16×40 foot deck and replaced my front porch too. All composite. It looks great! And they were fast and very communicative so that I never had to wonder if they were coming to my job site or not. I’d highly recommend them!”

Custom Patio and Deck Installation FAQs

Frequently asked questions

How long does it take to build a custom deck?

Most standard deck builds are completed in three to seven days depending on size, complexity, and material availability. Larger projects with covered structures, built-in features, or multi-level designs may take longer. We provide a realistic timeline with every estimate so you can plan accordingly.

Do you handle permits for deck construction in New York and Pennsylvania?

Yes. Deck construction almost always requires a building permit, and requirements vary by municipality. We manage the permitting process on your behalf to ensure your deck is code-compliant, structurally inspected, and fully documented — which matters for both safety and resale.

What is the difference between composite and pressure-treated wood decking?

Pressure-treated wood is cost-effective upfront and takes paint or stain well, but requires regular sealing and maintenance to hold up against moisture and freeze-thaw cycles. Composite decking costs more initially but is highly resistant to rot, fading, and splintering — and requires little more than occasional cleaning. We’ll help you weigh the long-term tradeoffs for your specific situation.

Can you repair or reinforce an existing deck instead of replacing it?

In many cases, yes. If your decking surface is worn but the framing and ledger board are structurally sound, a surface replacement or targeted repairs can extend the life of your deck significantly. We assess every existing structure honestly and will tell you whether repair or replacement makes more sense — and why.

Will a deck addition increase my home’s value?

Yes. A well-built deck is consistently ranked among the higher-return outdoor improvements for resale value. In the Western New York and Northern Pennsylvania market, usable outdoor space is a genuine selling point, and a professionally built, permitted deck adds both appraised value and buyer appeal.

What time of year is best for deck construction in Western New York?

Late spring through early fall is the ideal window — typically May through October — when ground conditions are stable and weather allows for consistent scheduling. That said, we book up quickly in peak season. If you’re planning a deck for summer use, scheduling your estimate in late winter or early spring gives you the best chance of securing your preferred start date.
