Labor cost to install redwood siding

The labor cost to install redwood siding varies according to the type of siding panels, local real estate values, and the region that the home is in. Costs fluctuate between $1.89 to $4.68 per square foot. It is best to get 3-7 quotes from local contractors to compare pricing.

Wood Siding Repair Cost

Repairing wood siding involves removing affected panels, treating the area for water/pest damage, replacing the panels with new ones, then finishing to match the existing siding. 

As wood siding is a natural material, it is quite common that it would need repairs from time to time to keep the structural integrity intact. Small isolated areas cost less to repair and most installers will charge approximately $100-150 per section, while repair work to large sections can cost $50-70 an hour. It is in your favor to get that maintenance done as early as possible. 

Installing redwood sliding

Whether you DIY or hire a contractor, there are a few essential steps to take before installing your redwood siding.

First of all, you must allow your wood 1-2 weeks to adjust to the climate of your site before you begin the installation. Even if sourced from a local supplier, the wood has likely been stored in different conditions to those of the outdoors on your property. It is very costly to install the wood too soon after it arrives at the site – the wood needs time to settle. Stack and store your wood siding outdoors on a dry, flat surface using 2×4 pilings to allow air to circulate under the pile. Do not store the lumber indoors with drywall or fresh concrete, or near artificial heating/cooling.

“It must adjust to the natural conditions where it will reside.” – Buffalo Lumber Co.

If you are planning to DIY, first do proper research regarding air spaces, water run-off, and finishing. Use stainless steel siding nails as other types will stain the wood.

Additional cost factors of redwood siding

Existing Siding: If you already have wood siding that you want to replace, you will have to factor in the costs to remove and dispose of the existing siding – this can add up to $2000 to your project.

Supplier Location: buying siding from a local supplier is more cost-effective, as well as better for the environment. It also helps your local economy when you support local businesses.

Building permit: check if your local building codes require you to obtain a building permit to install the wood siding.

Priming and Sealing: proper finishing of wood siding is essential to ensure a long life span for your exterior. By investing in this initial stage, you will save on long-term costs.

Benefits of redwood siding

Aesthetic beauty: tannins give redwood a rich reddish-brown color that, giving houses a rustic charm.

Pest-repelling: redwood is naturally resistant to insects and disease thanks to chemicals naturally present in the wood.

Rot-resistant: redwood’s natural tannins and chemicals make it resistant to rot.

Fire-resistant: redwood has Class B compliance according to California fire safety law. The same tannins that make the wood red, and repel insects, make the wood resistant to fire.

Sustainable building material: redwood (Sequoia sempervirens), is a fast-growing tall tree. For industrial use, it is grown in sustainable redwood forests. This material also decomposes naturally if left in a landfill.

Reduce carbon: redwood trees absorb carbon and hold it locked into their wood fiber (carbon sequestration), which reduces the carbon footprint of your build.

Physical attributes: redwood is a lightweight softwood that is easy to install.

Long life span: with a good maintenance plan and proper finishing, redwood siding will last for many decades.

Tips on hiring a siding installer

If you plan to hire a professional contractor, check references and reviews, and get quotations from more than 3 companies. Beware of bids that come in a lot higher or lower than the rest as they may not understand the scope of works. Get a written estimate and ask to see portfolio pictures.

It is best to find an installer with a proven track record of successful redwood siding installation, especially one familiar with installing the profile style that you prefer.

Finishing and Maintaining Redwood Siding

Regular maintenance on redwood siding and a finish that preserves the integrity of the wood will keep it good for 30-50 years. Transparent stains will preserve the natural aesthetic of the wood, and also protect it from mildew and sun damage. Varnishes and polyurethane coatings are not advised as they will crack and peel very quickly, ruining the appearance of the wood.

If you choose to paint redwood siding, it must be primed to prevent resins from bleeding through the paint.

To save on long-term costs, inspect your redwood siding annually to check for any areas requiring repairs – then fix those areas as soon as possible.

Cleaning redwood siding

Simply spray your garden hose lightly on redwood siding to clean it. Hosing reduces dirt build-up, and the need for more intense cleaning regimes later on. Clean during dry weather to ensure that the wood will dry out properly before applying new finishes. For a more intense clean, buildingadvisor.com suggests using a low-pressure sprayer or sponge to apply a cleaning solution. High-pressure water can cause damage to the wood and the integrity of the installation, especially weathered wood.

Use a mild detergent if there is no staining or mildew. A bleaching agent can be applied to darker sections to blend them in. [source: https://buildingadvisor.com/how-to-clean-and-stain-weathered-redwood-siding/]

For severe cases of mildew, hiring a professional pressure washing company experienced with cleaning siding is advisable.

Redwood Dutch Lap: (Cove Lap, German Lap, and WWPA 105), this profile has a curved channel that tucks under the board above when installed. From a distance, the Dutch Lap profile gives a slight ‘log cabin’ impression and is a more cost-effective option than an actual log profile.

Redwood Rabbeted Bevel has a notched butt end and a saw-textured face. Also known as ‘Dolly Varden’, it is easier to install than the Clapboard Bevel siding option, though it gives the same appearance. Panels fit together to protect joints from water damage. This option costs slightly more than the Clapboard Bevel due to the notch cut.

Redwood rabbeted bevel

Redwood Clapboard Bevel: is a bevel siding with a triangular profile, a square butt end, and a saw-textured face. Though it costs less than the Rabbeted Bevel, it is not as easy to install, so labor costs may be higher.

Redwood T&G: is beveled on the edges to create a ‘V’ indent. The depth/angle of the bevel determines the prominence of the groove on the wall. Tongue & Groove SIDING is usually graded to the rough face unless requested otherwise for a higher price (one side is rough, and the other smooth). T&G Wood Siding is a versatile option that can be installed in various ways, making it a cost-effective best seller.

Channel Lap: traditionally has a 1/2” overlap and a 1” to 1 1/4” inch “reveal”. When installed, the gaps create a channel effect between siding boards. This option has a rustic, rough-hewn, textured appearance. Relatively simple to install with minimal wastage, it can be installed in a horizontal, vertical, or diagonal pattern. It is good for wet regions as the overlaps act as weather protection for the frame allowing the panels to ‘breathe’ when there is moisture in the atmosphere. Moisture levels should therefore have no adverse effects on the appearance of the siding.

Redwood Shiplap: is a type of Drop Lap siding with a flush joint profile. One side of the board overlaps the next board to create a clean joint. It can be installed either horizontally or vertically.

FAQ's

According to Mendocino Redwood, the “Redwood region currently totals approximately 2.2 million acres with a mix of industrial forest lands, non-industrial forest lands, parks, reserves, and conservation lands.”

Though old-growth redwood is protected, commercial redwood forestlands provide sustainable lumber supplies of smaller and younger trees. These forests comply with the California Forest Practices Act and their lumber is FSC certified.

“Redwood is a renewable, recyclable and biodegradable resource.” – Mendocino Redwood

Redwood is a more eco-friendly and sustainable building material than man-made options. Those rely on fossil fuels and chemicals in the manufacturing process. The growth of redwood trees is augmented by free solar energy, and growing the redwood forests help to reduce carbon emissions in the atmosphere. As redwood (Sequoia Sempervirens) is a fast-growing species, redwood forests can absorb a lot of carbon dioxide from the atmosphere as the trees grow. The lumber stores the carbon in the wood fiber (known as carbon sequestration), keeping it out of the atmosphere and reducing the carbon footprint of your build.

Yes. Redwood is an excellent option for siding in all climates. The natural tannins present in redwood give this softwood great benefits. The distinctive rich color of redwood allows for an aesthetically pleasing exterior. The wood absorbs and retains finishes very well and is low maintenance. It is naturally fire-resistant, insect-resistant, and resistant to decay. With redwood siding you can also be confident of your siding keeping its profile well and resisting warping, shrinking, and cupping.


Redwood is naturally fire-resistant due to the unique tannins present in the wood. These same tannins make the wood resistant to insects and decay, meaning that the wood does not need to be treated with any chemical additives. In turn, costly fire retardant treatments are not necessary on redwood.

According to Mendocino Redwood, “Redwood has been declared ‘safe to use in California’s Wildland-Urban Interface (WUI) areas.’”

If redwood siding is constantly exposed to UV rays, the wood will dry out and become vulnerable to environmental damage. In wet climates, mildew often grows on wood siding. Though redwood is naturally resistant to mildew, if the siding has been treated with finishing oils it will be more susceptible to mildew.

Redwood siding can last for many decades if it is well maintained. Whether redwood is treated with transparent stain or paint, a light maintenance plan of every 3-5 years is optimal to prevent mildew. A maintenance plan will help to preserve the structural integrity of the wood.

Redwood is more cost-effective than many other building materials. It falls in the mid-range of materials. As the wood is available in longer lengths (due to redwood being a tall tree), the need for joints and seams is reduced.


Redwood will last longer than cedar if properly maintained. As redwood is 23% harder than cedar, it is the more durable wood. Redwood has more natural tannins and chemicals than cedar that give it beneficial properties. The beneficial properties of redwood mean that it requires less maintenance than cedar over time.

As redwood is a lightweight softwood it is relatively easy to install. DIY enthusiasts should first research the correct methods to installing the specific siding profile they have chosen to avoid costly mistakes.

Redwood is a beautiful warm wood that is inherently durable and stable. Real wood gives a home a timeless look that is grounding and cozy. Wood is easy to install and is an eco-friendly renewable resource.

Redwood can be easily stained or painted, but maintenance every few years will keep the wood in good condition. As redwood is naturally repellant to insects and disease, it is a sound option for siding.
