Portable Buildings & Barns

Every building we deliver comes with a 1-year workmanship and materials warranty, plus full coverage under applicable manufacturer warranties. We stand behind what we build — because your satisfaction is how we've stayed in business since 1992.

LP Smart Siding: 8-year warranty on painted buildings. If properly maintained per manufacturer specs (kept dry and painted), LP Smart Siding carries a 50-year limited warranty. We don't just use it — we trust it.
Paint: Two coats of high-quality semi-gloss applied over primed LP Smart Siding. Backed by a 20-year limited warranty.
Framing Lumber: Standard and premium buildings use #1 grade lumber for best appearance. Value and Econo models use #2 grade. All floor joists are pressure treated to protect against termites and moisture.
Standard Flooring: 5/8” subfloor on 2×6 floor joists spaced 16” apart — built solid from the ground up.
Log & Lap Siding: Kiln-dried white pine, sealed with a Sherwin-Williams DeckScape two-coat process — a quick base coat followed by a UV-protective finish coat that shields against sun damage, the harshest enemy of any outdoor wood structure.

Extended Workmanship Warranties

Going beyond the standard 1-year, our extended workmanship warranties give you years of additional peace of mind — included with the building styles listed below, at no extra cost.
