In most jurisdictions, yes — any permanent structure attached to or anchored in concrete requires a building permit. We provide stamped engineering drawings and structural calculations to support your permit application. Many of our clients find the permit process straightforward with our documentation package.

A standard TS-12 or TS-24 typically installs in 2–3 days once the concrete footings have cured (footings cure in 7–14 days). Larger models like the TS-44 and TS-64 take 3–5 days. We work with you to schedule installation around your schedule and weather windows.

We stand behind our work. The structural steel base plates and connections carry a 10-year warranty. Douglas Fir timber is warrantied against defects for 5 years. Glass roof panels carry the manufacturer's warranty (typically 10 years). We also offer annual maintenance inspection packages.

Yes — if the existing concrete is at least 4 inches thick and in good condition, we can core-drill anchor bolt holes and mount directly. Shawn will evaluate your existing slab during the site assessment. New pads are poured to our spec at 6–8 inches with rebar.

Properly finished Douglas Fir is low maintenance. We apply a penetrating oil finish before delivery. You'll want to re-coat every 2–4 years depending on sun and rain exposure. Unlike paint, the oil soaks in and never peels. A pressure wash and one-day re-coat is all it takes.

Yes. All structures are engineered to IBC standards for local snow and wind loads. We specify the load requirements for your location during the quote process. Pacific Northwest installations are typically designed for 25–40 PSF ground snow load and 110 MPH wind exposure.

TimberShield structures are installed by our team — they are not DIY kits. The precision of the V-leg geometry and the anchor bolt placement requires professional installation. We handle everything from footing layout to final finish inspection.

Current lead times are 6–10 weeks from signed contract to installation start. This includes fabrication, finishing, and scheduling. During peak season (spring/summer) lead times can extend to 12 weeks. Contact us early if you have a specific event or opening date.

Within limits, yes. The 18-foot depth (front to back) is fixed by the V-leg geometry. Width is modular in 12-foot bay increments — so 12, 24, 44, or 64 feet wide. Custom widths between standard sizes can be discussed with Shawn during the quote process.

Currently we serve Washington, Oregon, California, Arizona, and Nevada. We are actively expanding — if you're outside these states, contact us anyway. Shawn evaluates out-of-area projects case by case, particularly for larger commercial and transit installations.
