Written project scope

Southern Maine Deck Builders plans and builds new decks and complete deck replacements in South Portland, ME, using pressure-treated wood, composite or PVC.

Basic pressure-treated decks have a planning figure of about $80 per square foot with a $10,000 minimum. Complex or upgraded work is about $100 to $120 per square foot, and composite projects have a $15,000 minimum. None of these figures is a binding quote.

Each project starts with a site review of the ledger, footings, drainage and access, followed by a written scope. Permit and setback requirements are confirmed with the city for each parcel.

Why choose deck builders in South Portland, ME?

You should choose a deck builder who explains the structure before the finish boards. Our planning starts with the house connection, the supports and the route to the yard, then moves to layout, railings and material.

That order keeps estimates comparable, because two bids only line up when demolition, framing, stairs and railings are described the same way.

  • A written scope for your South Portland property that names the ledger, footings, stairs and railings, so you can compare our estimate line by line against any other bid.
  • Plain planning figures before design work goes far: about $80 per square foot for basic pressure-treated decks, a $10,000 project minimum and a $15,000 minimum for composite.
  • One point of contact from the first measurement through the final walkthrough, so questions about framing, access or material samples go to the person who knows your plan.

What deck material suits South Portland homes?

The right material depends on how much upkeep you want, how the deck faces the sun and how it will be used. Here is how our three project types compare.

Pressure-treated wood decks

Pressure-treated lumber is a direct way to build a sturdy, practical deck. It cuts and fastens with standard tools, takes stain or paint, and keeps the budget closest to our basic planning figure of about $80 per square foot.

Wood asks for regular attention. Plan on cleaning, checking fasteners and refreshing the finish as boards weather, and expect some surface cracks and color change over time.

If you enjoy that kind of seasonal care, wood is a sensible, honest choice.

Composite and PVC decking

Composite and PVC boards trade some upfront cost for less finish work. They do not need staining, and the color comes with the board.

Composite projects start at a $15,000 minimum, and we quote each one individually.

These boards still need cleaning, with installation details drawn from the selected product's instructions for gaps and fixings. We also follow that guidance for airflow beneath the surface.

If you select Trex, for example, we work from the current documents on the Trex installation downloads page.

Complete deck replacement

Complete replacement makes sense when the frame, supports or house connection are uncertain enough that new boards would only hide the problem. We remove the old deck, open up the connection at the house and build a new structure from the footings up.

We make the replacement recommendation in writing after looking underneath. If rot, undersized framing or weak attachment shows up, the scope says so plainly.

We do not call an existing deck safe based on photos.

What keeps a deck connection sound?

Ledger and flashing

The ledger board ties the deck to your house, so we check the rim behind it, plan fasteners for that wall and lap flashing so water sheds away from siding and framing.

Hidden fasteners and hardware

Hidden fastener clips and screws must match the board line you select. We use the hardware that product's instructions call for, along with connectors and coatings suited to treated lumber.

Door threshold

The step from your door onto the deck should feel natural and keep water out. We set deck height against the threshold, allow for board movement and leave room for drainage.

Not sure how to plan a deck project in South Portland?

  1. Two men talk on a lawn behind a light blue clapboard house; one holds papers while the other points toward the house.

    Site visit and measurements

    We visit the property, measure the house wall, entry height and yard, and look at any existing deck from above and below. We also walk the delivery route and note gates, slopes and parking so the estimate and written scope reflect how materials actually reach the work area.

  2. Undecked wood deck framing with joists set on concrete blocks on a lawn in front of a cedar-shingled house.

    Footings and framing

    Construction begins with layout, footings and the ledger connection, followed by beams, joists and blocking set to the written plan. We keep the frame open for any required inspection and review it before decking goes down, because the structure is hard to see once boards cover it.

  3. Two people stand on a finished low wood-toned deck with a single step behind a gray shingled house on a lawn

    Final walkthrough

    After decking, railings and stairs are installed, we walk the finished deck with you against the written scope, item by item. We review care for your chosen material, point out the ledger flashing and stair details, and clear debris from the yard before we call the project complete.

What should your South Portland lot plan show?

Footing layout

Footings are sized and placed for your deck's actual loads and the ground conditions we find on site. We confirm depth and size requirements for your parcel with the city before digging.

Drainage and airflow

Water from roofs, downspouts and slopes should move away from the footings, and air should reach the framing. The plan notes grade, downspout locations and open space beneath the deck.

Site access

Lumber, boards and debris need a workable route between the street and the build area. We look at gates, fences, plantings, utility areas and slopes on your actual property.

What should we check before building in South Portland?

Every South Portland parcel is different, so we check yours directly. That means the distance from the deck to property lines, the existing deck's condition, the wall where the ledger will attach and any slope, trees or structures that affect layout.

Permits, setbacks and inspection steps are set by the city, and we review them for your specific address through the Official South Portland municipal website. For structural reference, the American Wood Council decks resources offer general guidance, and local rules govern your project.

Everything we find goes into a written scope listing layout, materials, demolition, stairs and railings. You review it before anything is ordered, municipal decisions stay with the city, and the outside guides we cite inform our planning without endorsing our work.

When should I start planning a South Portland deck?

You should start planning a South Portland deck well before you have a firm date in mind. Design choices, material selection, any municipal review and our schedule all take time, so we set dates only after the site review and written scope.

Weather and access also shape when exterior work can proceed.

How should the deck work day to day?

Railings and guards

Guard placement shapes the view and how furniture fits. We plan post spacing, rail height and openings around where you will sit, then confirm the requirements for your project.

Stairs and landings

Stairs should land where you actually walk, toward the driveway, garden or side door. We plan the run, any landing and the ground surface at the bottom so the route feels steady.

Sun and shade

Exposure changes how a deck gets used and how boards feel underfoot. We note afternoon sun and seating areas, and we suggest setting real board samples outside before you choose a color.

How much does a deck cost in South Portland?

A deck in South Portland costs about $80 per square foot for basic pressure-treated work, with a $10,000 project minimum. Complex or upgraded designs run about $100 to $120 per square foot.

Composite projects start at $15,000 and are quoted individually. The minimum applies when area times rate is lower.
