Learn MoreReach out by phone or form. We will ask a few quick questions - roughly what you are looking for, where on your property, and your general timeline. You do not need to have everything figured out. We respond within 1 business day and schedule a free on-site visit at a time that works for you.
We come to your property, take measurements, assess the yard and any slope, and walk through your options with you. We look at where the structure attaches to your house and discuss materials, design, and features. Within a few days you receive a written proposal with a full price breakdown - no surprises.
Once you approve the proposal, we pull the permit from Williamsport's Bureau of Codes on your behalf. When the permit is approved, our crew arrives, builds the structure, passes the city inspection, and hauls away all debris. You get a copy of the permit and inspection record - and a deck or fence you can use right away.
We are registered with the Pennsylvania Attorney General's Home Improvement Contractor program and carry full general liability coverage. We provide proof of both before any work starts - no exceptions.
We come to your property, measure, and give you a written proposal at no cost. You will have a clear, itemized price before anyone picks up a tool. There is no pressure to decide on the spot.
We have been building decks and fences in Lycoming County since 2015. We know the local permit offices, the frost depths that matter here, and the housing stock in Williamsport's neighborhoods.
Every project starts with a signed written contract that spells out the full scope, materials, timeline, and price. We do not add charges for things that were always part of the job. You know the total before we break ground.

"They built a composite deck off our back door last spring and finished on time. The footings were deep - they explained the frost line requirement before we even signed the contract, which I appreciated. The crew cleaned up every evening and the final inspection passed first try."
Brian K., Montoursville - Custom deck design and build
"Our old wood deck was soft in two spots after the last winter. They assessed it honestly - told us two boards and a joist needed replacing, not the whole deck. Repair was done in a day and it feels as solid as new. Straight talk and fair pricing."
Diane M., Muncy - Deck repair and replacement
"We wanted a vinyl fence for the backyard before summer. They came out, measured, gave us a written quote the next day, and had everything installed within two weeks of signing. The fence line is straight and the posts are solid - no wobble at all."
Carrie S., Jersey Shore - Vinyl fence installation

In north-central Pennsylvania, footings must go at least 36 to 42 inches below grade to sit below the frost line. Shallow footings get pushed upward by freeze-thaw cycles each winter, causing the deck to shift and crack over time. The North American Deck and Railing Association recommends confirming footing depth requirements with your local building office before construction begins.
Composite decking handles Williamsport's 40-inch annual rainfall far better than untreated wood, since it does not absorb moisture or develop rot. Pressure-treated wood is a solid option when sealed regularly, but composite boards require almost no annual maintenance. For most homeowners planning to stay in their home long-term, composite tends to cost less over the life of the deck.
Yes - any deck attached to your home or elevated more than 30 inches off the ground requires a permit from Williamsport's Bureau of Codes and Building Inspection. A permitted deck gets inspected by a city official and is documented in your property records, which matters when you sell or refinance. Skipping the permit is the single fastest way to create a problem at the worst possible time.
The quality of a deck is mostly invisible once the boards go down - it lives in the footings, the joist spacing, and the ledger flashing at the wall connection. A deck built with properly sized hardware, correctly spaced joists, and a waterproof ledger barrier at the house will last 25 years. One built to cut corners will show problems within two to five winters.
The best build window in Williamsport runs from late April through September. Spring is when most homeowners start calling, so local contractors fill up fast. If you want your deck ready before Memorial Day weekend, reaching out in February or March gives you the best chance of landing a start date that works with your schedule.
Research from the National Association of Realtors Remodeling Impact Report consistently shows that a wood deck recoups roughly 65 to 75 percent of its cost at resale. Beyond the number, homeowners who add a deck rank it among the projects they are most satisfied with - because it changes how they actually use their home, not just how it looks from the street.
Williamsport Deck & Fence is a licensed and insured deck builder company based in Williamsport, PA, serving Lycoming County and 12 surrounding communities since 2015.
We are registered under Pennsylvania's Home Improvement Contractor program, administered by the Pennsylvania Attorney General's office, which requires contractors to carry liability insurance and maintain a clean record for homeowner complaints.
Since 2015, we have completed deck, fence, pergola, and outdoor structure projects across north-central Pennsylvania, working with homeowners in both the city's older Victorian-era neighborhoods and newer suburban developments across the county.
An unpermitted deck shows up in almost every home inspection. Buyers' lenders often require it to be torn down or rebuilt before closing - at the seller's expense. The Pennsylvania Uniform Construction Code applies statewide, and Williamsport enforces it.
Soft or spongy boards, visible rot, or a deck that sways under foot traffic all point to structural issues that repair alone may not fix. If the frame and footings are in good shape, surface repair makes sense. If the framing is compromised, replacement is usually safer and more cost-effective long-term.
A complete contract names the materials (brand, grade, dimensions), the total price, a payment schedule, who pulls the permit, and a start-and-finish timeline. Pennsylvania's Home Improvement Consumer Protection Act requires written contracts for projects over $500 - do not sign anything that leaves these details open.

Williamsport is the largest city in Lycoming County and the county seat of north-central Pennsylvania, with a population of roughly 28,000 to 29,000 residents. The city sits along the West Branch of the Susquehanna River, and its geography - from the flat river corridor to the hillside neighborhoods above downtown - creates a variety of yard types and site conditions that affect how outdoor structures are designed and built.
Much of the city's residential housing stock dates to the late 19th and early 20th century, reflecting the wealth that came with Williamsport's lumber boom era. Neighborhoods like Vallamont and the West End are filled with Victorian and early Colonial-style homes, and the stretch of grand mansions along West Fourth Street - known locally as Millionaires' Row - is a visible reminder of that era. Newer residential development sits on the city's edges, in townships like Loyalsock and in communities out toward Muncy and Montoursville.
The city is best known outside Pennsylvania as the home of Little League Baseball and the annual Little League Baseball World Series, held each August in South Williamsport. Major employers include UPMC Susquehanna and Pennsylvania College of Technology, which bring a steady base of long-term residents who invest in their properties. Whether you live in one of the city's older in-town neighborhoods or in the newer suburban areas to the north, our crew works across the entire Williamsport area and knows the site conditions that come with each part of town.
