PowerLift Doors by SEK Designs
378 Old Country Rd, Melville, NY 11747

Welcome to our family-owned and operated business right here on Long Island! We welcome the opportunity to be involved in your door or opening wall project.

We design, build, deliver, install and support PowerLift doors and walls right here in our own shop. Our position as leader in the hydraulic door business is evidenced by tens of thousands of customers around North America.
A PowerLift door is the best choice for your new aviation, commercial, farm or architectural project. We also have extensive experience replacing old sliding, bifold, fabric or overhead doors with a PowerLift retrofit. Our retrofit doors will expand your clear opening height and width for improved access.
We’ll be glad to stop by next time we’re in your area with our tape measure. We can look over your new or older building and suggest an attractive, zero-maintenance PowerLift solution. We’re only a phone call away at any stage of your project and are there for support long after completion!
