Why Choose Grinyer?
The Grinyer System replaces manual tape measuring and on-site cutting with precision digital measuring and robotic factory finishing.
This new process allows us to custom fit fully-finished doors while keeping your existing frames, eliminating demolition and preventing misalignment.
The result is doors installed right the first time, engineered to last, and overall project cost savings passed to you.
The Grinyer System Difference
Two approaches. Two different results.
QUALITY NAME-BRAND MATERIALS
Superior Doors Built to Last
We use name-brand door slabs from trusted manufacturers like Masonite and JELD-WEN. Superior materials provide lasting strength, durability, and results built to last.
DIGITAL MEASURING
Doors that Fit & Function Better
We use high-tech digital measuring to capture precise dimensions of your existing door frames, eliminating guesswork and ensuring consistent door alignment throughout your home.
