Make Room for the Way You Use the Deck

The board color can wait until we know the deck gives you room to sit and move. We look at where furniture will go, how you will get out to the yard and where the stairs can land. A surface that is easy to care for will not make a cramped layout work better.

A finished deck is easier to judge when you can see the board color beside the house, the stair placement and the railing together.

What Homeowners Say About Our Deck Work

A finished-deck photo cannot tell you what the process felt like. Reviews can show how homeowners describe the planning and build.

What Our Composite Decking Service Covers

For a new deck, we can handle design, footings, framing, boards, stairs and railings. We also offer 3D design and permit acquisition. Your estimate should name the selected material and make clear which parts of that work we have agreed to do at your property.

Skirting, privacy screens or an underdeck drainage system may fit the layout. They are separate choices, not features we assume every deck needs. We will talk through them while the design is still open so you can see what each one adds to the scope.

Already have a deck and thinking about a different surface? Tell us what is there now. We need to look at the frame and the board requirements before deciding what work makes sense. New boards will not solve a weak structure underneath.

Build the Frame for the Composite Surface

Composite boards need a sound frame underneath. We look at the height, grade, stair landing and railing positions before laying out footings, joists and blocking. If you already have a deck, we need to look at its structure before deciding whether new boards make sense. A new surface will not fix support that is not right for the job.

If you want a picture-frame edge or a board that breaks up a long run, we plan support for those joints and edges while the frame is still open. The border, stairs and posts all need to work with the board direction. We would rather settle that on the plan than try to add it after framing is finished.

The exact board matters for fastening too. Grooved boards and solid-edge pieces may use different fasteners, and spacing and movement allowances vary by product. We follow the current instructions for the collection you choose and put those details in the build plan, especially around borders and stairs.

Choose a Surface After the Deck Layout Makes Sense

Composite decking is a manufactured board made with plastics and organic material such as wood fiber. It can save you the routine sanding, staining and sealing of traditional wood, but it still needs cleaning. We look at colors outside beside your siding and railing rather than ask you to decide from a small sample indoors. Darker boards can feel warmer in afternoon sun, which matters if the deck is where you walk barefoot or spend time with the kids.

We also look at where snow, ice and meltwater would go on your deck. Any outdoor surface can get slippery in winter. The gaps between boards, the path for runoff and the space you need to clear debris all belong in the design. We will go through care instructions for the exact product, not promise a deck you never have to maintain.

Trex and TimberTech give us composite options to compare by finish, board profile, installation details and cost for the complete deck. We check the collection and availability before naming a product in your estimate. TimberTech sells PVC as well, but PVC is a different material without the wood filler found in many composites. If that distinction matters to you, we can compare both instead of treating the brands or board types as interchangeable.

What Changes a Composite Deck Estimate?

The boards matter, but they are not the whole estimate. Size, height, yard access, footings, framing, stairs, railings and the particular composite board all affect the work. A border or underdeck system can change it again. Once we have seen the property and talked through the layout, we can give you a written scope rather than a square-foot number with the important pieces left out.

When Can a Composite Deck Move to Construction?

Timing depends on the design, board availability, permitting and the work agreed for your property. We will discuss those dependencies with you instead of promising the same start date for every deck.

Check the Permit Office for Your Address

If your home is inside Idaho Falls city limits, the City of Idaho Falls Building Division is the permit authority. The city says a permit must be obtained before regulated construction begins. We confirm the jurisdiction and proposed work first, then say whether permit acquisition is included in your estimate.

Why the Board and Structure Belong in One Plan

A composite board is only as useful as the deck it sits on. If a border is chosen without enough support, or a railing post conflicts with the stairs, the problem shows up during the build. Planning the surface, frame and access together helps us catch those conflicts while the design can still change.

We can design the deck, compare composite with PVC and wood, and show you a 3D model when it helps you make a choice. Then we identify the material and construction details in the proposal. You should know what is under the boards as well as what they look like.

How We Start a Composite Deck Project

We start with the way you want to use the space, then work toward the material and construction scope. You do not have to choose a board before we have looked at the yard.

  1. Walk the Property and Talk About Daily Use

    Tell us where you want to sit, eat or spend time together, and how people will get to the yard. We look at sun, grade, doors, stairs and the space available for the deck.

  2. Compare the Design and Boards

    We develop the layout and talk through available composite boards by color, feel, care and cost for the whole project. If a 3D model would make the layout easier to picture, we can include that in the design conversation. The estimate names the proposed board and the work behind it.

  3. Agree on the Scope and Next Steps

    We confirm material availability, foundation and framing details, and the permit plan for your property's jurisdiction. Permit acquisition can be included in the agreed work. We will explain what has to happen before construction rather than treating an approval or start date as automatic.

Understand Coverage and When Composite May Not Fit

We won't treat a board maker's warranty as coverage for the entire deck. We'll go through the selected product's terms and any workmanship coverage in the project agreement before you decide.

If you prefer the grain and variation of real wood and do not mind the upkeep, let's compare wood. If you want a board without wood filler, we can look at PVC. Composite is an option, not the right answer for every yard.

Composite Decking Questions

What is composite decking and how does it work?

It is a manufactured board made from plastics and organic material such as wood fiber; many versions have a protective cap. The boards make up the walking surface. We plan the frame separately and use the spacing and fasteners required for the board you choose.

What are the benefits of composite decking installation?

You get a wood-look surface without wood's regular sanding, staining and sealing routine, plus choices in color and texture. It still needs cleaning. The bigger benefit comes when the board, supporting frame, stairs and railings are planned as one deck.

Do composite deck builders offer custom designs?

Yes. We design around the yard, the way you use it and the access from your home. We can work board direction, borders, stairs, railings and a 3D model into the plan before the construction scope is final.

How does composite decking compare to wood?

Wood has natural grain and can be refinished in ways composite cannot. Composite offers a more consistent manufactured look with less recurring surface treatment. We compare both by appearance, care and the cost of the complete deck, not just the boards.

Does the City of Idaho Falls require a permit for a composite deck?

The permit question applies to the deck project, not just the surface. Inside city jurisdiction, the City of Idaho Falls Building Division says a permit is needed before regulated construction starts. We check the property's location and the proposed work, then identify permit acquisition in the estimate if it is part of our scope.

When is composite decking the wrong choice?

If you want real wood grain, plan to refinish the surface in the traditional way, or find that another material better fits the complete project budget, composite may not be right for you. PVC is also worth comparing if you want a board without wood filler. We will walk through the actual options for your home.
