New Siding Installation
A new siding upgrade protects your home from our harsh Onaway ID climate. Faded, buckling panels get worse over time. Choose licensed, warranty backed pros using quality siding systems, moisture control, and details for a durable - code tight exterior.
Siding Replacement
A siding replacement restores full protection when panels crack, fade, or fail over time. Local homeowners love our fast and fair siding estimates, how we explain the options, show up on time, and stand behind our work long after your new siding is installed.
Siding Damage Repairs
Siding repairs stop water intrusion after wind, hail, or flying debris and extend your exterior’s lifespan. Trust our 5 Star Onaway siding - our licensed crews handle emergency patches, photos for insurance, and lasting fixes to damaged panels on your home.
Onaway’s mill town setting means long winters, tall trees, and plenty of shade and snow stacking against lower walls. Old siding absorbs that punishment until it starts to rot, peel, and leak.
Replacing it with properly installed vinyl, fiber cement, or engineered wood siding puts a durable, low maintenance barrier between the weather and your framing. Your Onaway house or shop holds heat better, sheds water faster, and keeps the historic feel without the constant patch and paint routine.
Posted on Kevin CannonTrustindex verifies that the original source of the review is Google. Had a small roof repair after a home inspection that needed addressed within the month. They answered my call right away and were happy to help, fitting us in their schedule almost instantly. Luke and Alex were super nice and professional both on the phone and in person. Some poorly timed snow storms delayed them a few days but they were great at communicating what their plans were. Highly recommend these guys!Posted on SCTrustindex verifies that the original source of the review is Google. GCS went out right away to assess my roof, made the repair and gave ma great price for a new roof. They sent me photos during and upon completion of thr process. I dont live there full time, but my neighbor said they worked fast and furious to get it done. They did my roof during the winter, and completed it before the weather became a burden. Would definitely use them again for other projects I have coming up.Posted on Norman chesserTrustindex verifies that the original source of the review is Google. We hired this general contractor for our home renovation, and the results exceeded our expectations. The team was punctual, skilled, and communicated clearly throughout the project. They stayed on schedule and within budget while delivering high-quality workmanship. The entire process was smooth and stress-free. I would confidently recommend them for any construction or remodeling needs.Posted on Barbara FrananoTrustindex verifies that the original source of the review is Google. Our barn roof was damaged by a windstorm in December 2025. Our insurance appraiser estimated the cost to replace the damaged panels was less than our deductable so we were responsible out of pocket for the repairs. We contacted GCS, and Alex came out to give us an estimate for the repairs. His bid for parts and labor was less than the insurance estimate. We have also had leaks in other areas of the roof. Alex noticed the origional installers had used screws that were too small. He suggested removing the screws and replacing with the larger proper size and installing aditional screws to spec fastener pattern. They were able to come right away before weather got bad again, and did an outstanding job. We were very impressed by the level of professionalism and ease of interaction. We have no complaints! Thanks!Posted on Dan MaurerTrustindex verifies that the original source of the review is Google. GCS construction completed three separate projects at my home. New vinyl siding, new shed, and repair of a sagging garage door header. Alex and his crew did a great job and am very happy with the results of all the projects. Work was done in a professional and timely manner and I was kept apprised of what they were doing and they were available to answer all of my questions. I highly recommend GCS!Posted on Anne ETrustindex verifies that the original source of the review is Google. Alex did a phenomenal job on my home sealing and siding. He fixed the issue I had around my sliding glass door beautifully also.Posted on Laurie McGrawTrustindex verifies that the original source of the review is Google. I can't say enough about this company. They go above and beyond in customer service. We have worked with them on 3 projects (one of which is not complete yet and I will be writing a review when it is) They represent great quality workmanship, honesty, integrity, job completed in a timely manner, they clean up after themselves you will not have to walk around picking up empty drink bottles, garbage and debris, they take pride in what they do, you will not find them standing around on there cell phones. Luke, Alex and Caleb put up with all of my questions and non sense and are always kind and patient. I have not seen anything they are not capable of doing or willing to take on and do it well. Thank you guys for a fantastic experience. Highly recommend.Posted on Sandra ChavezTrustindex verifies that the original source of the review is Google. Amazing service definitely recommend!!!
"Top notch quality and service! They work hard to make sure all projects are done timely and with professional quality. Wouldn’t trust anyone else on the Palouse!"

What siding contractor services do we provide for Onaway and nearby timber country?
Onaway sits just northeast of Potlatch along State Highway 6, with homes and shops tucked into a historic mill community and the edge of timber ground. We install and replace fiber cement siding like HardiePlank, engineered wood such as LP SmartSide and Diamond Kote, vinyl siding, and steel siding for houses, barns, and mixed use buildings that grew up around the old mill.
Vinyl siding is a practical option here for owners looking for a budget friendly, low maintenance upgrade. It never needs paint, handles moisture and temperature swings well when installed correctly, and offers enough profiles and colors to match both older mill houses and newer country homes on the outskirts.
How do timber country and SH 6 weather affect siding around Onaway?
This area sees a blend of mountain and Palouse conditions:
- Heavy snow loads and sliding drifts against lower walls in tight lots and driveways.
- Cool, damp air along the Palouse River and around the mill corridor.
- Wind funneled along the SH 6 White Pine Scenic Byway pushing rain into west and south walls.
- Freeze thaw cycles that punish low grade siding and trim.
We back LP SmartSide, Diamond Kote, HardiePlank, vinyl, and steel siding with proper housewrap, flashings, and drainage details so the exterior can handle snow, rain, and shade without failing early.
What does a new siding installation look like for Onaway homes and shops?
Whether your place is on a town lot near Potlatch or on the way toward Princeton and Harvard, we follow a consistent process:
- Inspect framing, sheathing, and current siding for hidden rot and leaks.
- Study how rooflines, porches, and walkways move water toward or away from walls.
- Help you choose a system:
- HardiePlank lap siding for a clean, classic look with fiber cement durability.
- LP SmartSide lap or board and batten to complement timber and mill town architecture.
- Diamond Kote prefinished siding for long lasting color in a climate that is tough on paint.
- Vinyl siding packages when you want faster installation and minimal ongoing upkeep.
- Steel siding on shops and barns that see log trucks, equipment, and firewood every day.
We build to manufacturer standards and local conditions so your new exterior looks tight and stays that way.
What siding problems show up most often in Onaway and the Potlatch area?
Older exteriors around here often share the same issues:
- Soft, punky trim and siding near ground level where snow piles and water sit.
- Peeling paint and exposed substrate on south and west facing walls.
- Loose or brittle vinyl that has been patched over the years without addressing water paths.
- Rot around porch connections and roof to wall intersections.
- Cold spots and musty smells inside where moisture has worked past the siding.
We identify what needs immediate attention and then design a new siding package that shuts down those failure points.
Why do local owners mix engineered wood, vinyl, fiber cement, and steel on their Onaway projects?
In a historic mill town that also serves as a pass through to timber ground, buildings see a lot of different use:
- LP SmartSide suits older homes that need a wood look product with modern protection.
- Diamond Kote cuts down on repainting tall gables and steep roof transitions.
- HardiePlank offers fire resistance and stability near tree lines and logging corridors.
- Vinyl siding provides a low maintenance option for simple homes and rentals that still need curb appeal.
- Steel siding handles bumps, loaders, and everyday shop traffic without flinching.
We match material choice to how you use each structure, instead of forcing a single solution.
How can updated siding boost curb appeal in a small mill community?
On compact lots and narrow streets, exterior condition is obvious:
- Fresh siding tones down the patchwork look of older additions and remodels.
- New trim, soffits, and fascia clean up rooflines and overhangs that have been pieced together.
- Shop and home exteriors that match or complement each other make the whole property feel more intentional.
Whether you stay or sell, a modern siding package in vinyl, engineered wood, fiber cement, or steel gives the property a clear and confident first impression.
How do you get a siding estimate for a home or shop near Onaway?
We meet you on site so nothing gets missed. During your visit we:
- Walk all sides of the home or building, including tight alleys and back lot lines.
- Review LP SmartSide, Diamond Kote, HardiePlank, vinyl, and steel products that fit your budget and style.
- Explain repair versus replacement options and why we recommend each one.
- Deliver a written estimate with scope, materials, and scheduling expectations.
From small in town lots to rural properties toward Princeton and Harvard, we install siding built for timber country and SH 6 weather.
