Trex Signature railings are great for preserving views into a treed backyard or greenbelt.

Since Trex Signature railings are aluminum, they don't rust and are very low maintenance.

Trex Signature Railing with Cocktail Rail:

Trex decking with Signature railing and Trex Cocktail rail in Flagstaff AZ

This deck features Trex Transcends deck boards and Trex Signature railing.
The Trex Cocktail rail is attached with special brackets made by Trex.
Decking color: Vintage Lantern.

Trex Signature railing is all aluminum and therefore will not rust like wrought iron rails.

The deck steps have Trex deck boards for treads and Trex Fascia boards for risers.
The concrete landing pad and footers are colored concrete.

The Trex Signature posts on this deck were kept extra tall for future special lighting.
The Trex posts can be cut to any length. Code requires a minimum guardrail height of 36" for residential decks.

Wild Hog Brand Metal Railing:

Wild Hog welded wire is a great choice for a see-through railing.
Wild Hog come pre-painted in a matte black finish.

For this cabin, we framed the Wild Hog railing with Redwood.
We stained the redwood before installation with SuperDeck Cedar Toner.
We built the stairs from 4x12 Doug-Fir.
We stained each piece before installation to insure that the stain penetrated the end grain of the treads.

Flagstaff Fire Department Tests Different Deck Materials:

The Flagstaff Fire Department tested four brands of Composite deck materials and wood decking.  Trex was the only composite material that performed well:

"Most of the composite materials ignited easily and resulted in high to extreme fire severity (fig. 4).But Trex,* a material made from plastic and wood, performed well. Trex was more difficult to ignite than the other composites and ultimately self-extinguished (fig. 5). Trex's fire resistance appeared to result from its density. The composites that performed poorly were less dense."

As a TrexPro Deck contractor, I recommend Trex as the only composite decking material to use.  Typically a Trex deck is installed on Doug-Fir Framing members.  We stain the top edge of the framing members before applying the deck boards. This helps the framing to last longer and color coordinate with the Trex material (light colored framing would otherwise be visible between the recommended 1/4" gap in the deck boards).

Redwood Decks:

Due to the high cost and high maintenance of Redwood decks, we highly recommend considering Trex Composite decking.

However, here are a few samples of our Redwood decks.

One of our Redwood decks was featured in Stanley's Guide to Decks by David Toht:

Redwood Deck with Redwood handrails

We build our Redwood decks and handrails with corrosion resistant fasteners.  All deck boards are screwed to the joists, after the tops of the joists have been sealed for protection.

Redwood Deck and Redwood handrails, Flagstaff, AZ:

Redwood deck in Flagstaff Arizona

The deck above is built with 6" x 6" Redwood posts under the main deck.  The post to beam connection is a decorative metal 'T' bracket. This deck also has a 2x12 Redwood rim joist to match the redwood handrails and to give a nicer view from the street.

Below: unstained Redwood Handrail built to code requirements.

Redwood Handrail

All Guardrails must be at least 36" high.  Guardrails that are also Handrails must be between 34" and 38" high and must have a 'grippable' handrail that continues from the top of the stairs to the next full landing - See the picture below:

Redwood Staircase

Redwood deck and handrail with clear sealer:

Redwood deck in Kachina Village

We built this all Redwood deck in Kachina Village and installed a new concrete landing.

Notice the graspable handrail required by code on the left side of the staircase.

Decks 30" or more above ground require a guardrail.

We sealed the Redwood in these pictures with two coats of Sherwin-Williams brand 'clear' Acrylic sealer.

Decks in Flagstaff should be re-stained or water sealed at least every two years on the horizontal surfaces and at least every four years on the vertical surfaces.

Deck Footings:

Footing under a Redwood deck

In Flagstaff and Coconino county, decks are required to have 30" deep concrete footings reinforced with #4 Rebar.

In the deck above we used round concrete forms with Simpson brand brackets and a exterior rated GLB to hold up the deck.  Decks in the Flagstaff area must be built to withstand heavy snow loads.  (View the 'other guys' work here)

The deck framing is also required to be sealed with two coats by code.  We used a 'clear' sealer on this deck, which preserves the natural color of the Redwood decking and handrails as well as the Doug-Fir framing members. 

Redwood Railing Options:

Redwood Hand rail with Trex Cap

Short Spindle Style:

This style of handrail has the spindles ending on a Redwood 2'x4' about 3.5" above the deck surface.  This can be useful for shoveling snow if the rail is located in a high traffic area.  However this style is not as strong as the handrail pictured below.

Redwood Handrail with Trex Cap

Full Length Spindle Style:

This style of handrail is made of Redwood and the spindles continue down on to the Rim Joist of the deck.  This is our preferred method of handrail installation as it provides the maximum strength.

If you are thinking about replacing your existing deck boards with composite decking (Trex), remember that Trex requires 16" on center framing.  Typically Redwood decks are built with 24" on center framing.

New decks, deck expansions, and deck replacements often require plans and a permit, especially if the deck is 30" above the ground.  We can arrange for one of our plans drafters to meet with you to discuss your design and draft your plans (hourly rates apply).

Here is an example of a 12' x 16' Trex Deck with Redwood handrails.  The stairs also have a Trex Riser board installed.

These deck stairs are made from Trex Transcends deck boards and Trex Fascia boards.
The stair handrail for this deck is Trex Signature aluminum deck rail.

Trex stairs with Trex Signature Handrails in Flagstaff AZ

Here is an option for heavy duty stairs.
These stairs are made from 4" x 12" Doug-Fir stringers and treads:

The railings on the stairs pictured above are Redwood 2x2 spindles and Redwood 6x6 posts.
The stain is Sherwin-Williams SuperDeck solid color stain - 2 coats.
We put tread grip sand in the stain on top of the treads to give better traction in slippery conditions.

Proper Deck Building Procedures:

Providing proper drainage under the deck and away from the house is important. Also installing a moisture barrier between the deck ledger board and the house siding helps prevent damage to both the house and the deck from water.  For this deck, we installed Grip-Rite brand self-adhesive moister barrier before installing the ledger board.

Site Prep for a Deck in Flagstaff Arizona    Closeup of Decking Site Prep in a backyard in Flagstaff AZ

The picture below shows how we attach the deck ledger to house and the deck joists to the deck ledger.
We use Simpson SDWS timber screws to attach the ledger.  They are driven with a #40 Torx bit.
The joists are then attached to the ledger with Simpson JUS28 Joist hangers and Simpson SD screws instead of TKOs.
The Simpson screws hold tighter and longer than nails.
It is important to use 2 1/2" screws for the side going through the joist as they are angled to pass through the joist into the ledger.

Simpson Strong-Tie joist hangers and timber screws

In the picture above and below we used brown pressure treated lumber.  The lumber is pre-stained brown to cover the green preservative.
  This lumber is dense Fir, so it is incised during the pressure treating so that the preservative will penetrate further.

Joist to Beam Connections for Decks:

deck joist to beam connection

The picture above demonstrates the proper way to connect deck joists to a support beam.
For this deck, the treated lumber joists are connected to the Glue-Lam beam with Simpson Strong-Tie H2.5 Hurricane straps.
The H2.5 straps are installed using 1 1/2" Simpson Strong-Drive SD connector screws.

Notice that we applied a special deck tape to the top of the beam before installing the deck joists.
We also used full height blocking between the joists, fastened with hot-dipped galvanized nails.
The blocks are also fastened to the GLB, which adds to the overall strength of the deck.
We stained the GLB with a high-quality exterior stain.  (Always stain - never paint!)

Deck Tape - Trex Protect

Before installing the deck boards, it is important to seal the tops of the deck joists.
Pictured below is Trex Protect deck tape.
We prefer the Trex deck tape over other brands because it has a higher level of adhesion and comes in 1 5/8" wide rolls which is perfect for sealing deck joists.

Installing Trex Protect deck tape on the tops of deck joists

Hidden Fasteners vs. Screws

We have installed numerous decks using hidden fasteners and also numerous decks with color-matched screws.
The cost is about the same for both systems, however after years of experience building decks, our recommendation is to screw through the deck boards with color-matched finish deck screws. Screwing through the deck boards adds rigidity to the whole deck system.
Plus the deck boards stay put, whereas when using hidden fasteners such as the Trex Hideaway system, the deck boards tend to "inch worm" along the joists.

The following picture demonstrates the installation of Trex decking with concealed fasteners.  Notice how the top edge of the joists are stained before installing the deck boards.  The solid-color stain will help prevent moisture damage in the long run.  This is important in Flagstaff, due to monsoon rains in the summer and snow sitting on the deck in the winter.   However the newer deck tapes, especially Trex Protect tape do a better job of sealing the tops of deck joists.

Staining of top of joists before installing Trex Deck boards

Treated Lumber vs. untreated Doug-Fir

It is not necessary to use pressure treated lumber in Arizona due to the dry climate.
Regular Doug-fir joists will last for several decades as long as they are able to breath and are NOT painted.
However the building code requires that un-treated lumber exposed to weather be sealed with a paint or stain.
We have found that it is more cost effective to simply buy the pre-stained pressure treated lumber rather than spend hours staining regular doug-fir joists.
When opting to stain, it is imperative to use a non-film forming stain on joists. NEVER paint deck joist.
Painting deck joists will cause them to rot, since the moisture will not be able to escape.

Causes of Early Deck Failure:

We have been building decks for over 25 years.  During that time we have taken apart numerous decks built by "the other guys".
Some of the most common reasons for deck failure are:
1. Not sealing the tops of the joists.
2. Painting the joists.
3. Not spacing the deck boards properly.
4. Not using the proper connectors.
