We don't just craft good products. We create great solutions. Over the years, Woodfold has earned a reputation among designers, architects and homeowners as the go-to company when faced with a real challenge. How to turn an odd-shaped window into a work of art. How to divide a cavernous room into cozy retreats. How to assure better security without sacrificing eye appeal. We're able to do all this and more thanks to a unique combination of assets: exceptional design and engineering. timeless, traditional craftsmanship, using the finest hardwoods, the best man-made materials, the highest quality hardware. and of course, the most advanced technological advances in equipment, machinery and process workflow.
We go the extra steps. At Woodfold, that's a given. Each piece going into a Roll-Up Door, for example, is individually finished to assure absolute color integrity, top to bottom. Our Roll-Up and Accordion Doors are installed, tested and re-tested before shipment to ensure flawless performance. And prior to being stained or painted, every hardwood Shutter is hand-examined with ultraviolet light to expose even the tiniest fleck of glue which could affect the integrity of its finish.
Woodfold combines decades of craftsmanship with today's most advanced computers and machinery for an unsurpassed level of quality, efficiency and precision. Best part is, to us, it's just the beginning. After all, we're only 61 years old and that's quite young in our minds.
