Wood Sliding Doors
They Slide Sideways and Need No Headroom Above
A custom sliding door is the answer where a wall has no headroom for an overhead door. It is built to the opening, single-piece or bi-parting, with through-bolt construction for strength and less maintenance. They are common in warehousing and logistics, healthcare and large retail spaces.
- Custom, site-specific build, made to the opening and the wall beside it
- Single-piece or bi-parting to suit wide openings or split side room
- Through-bolt construction for strength and durability with less maintenance
- Manual or automatic operation, with safety mechanisms built in

Which Sliding Door Fits the Wall?
Whether the wall has room to one side or the opening is very wide, we match the sliding door to the opening and the space beside it.
Single-Slide Doors
A single door section that slides to one side, for openings with wall space beside them.
Bi-Parting Doors
Two door sections that part to each side, for wide openings or where side room is split.
Automatic Sliding
Powered sliding doors that open on approach, for high-traffic and accessible openings.
Custom Wood Build
Custom wood doors built to the opening with through-bolt construction, for spaces an overhead door cannot fit.

How It Works
From the First Call to a Door That Runs
Site Assessment
We measure the opening, headroom and side room, and look at how the door is used.
Scope and Fixed Quote
We spec the door, track and hardware and price it before the work starts. The quote is the invoice.
Scheduled Around You
We book the install around your shipping and production, including nights and weekends.
Install and Full Test
Certified crews install, align the track, set the rollers and run a full operational test.
Documented and Warranted
You get the paperwork for compliance and warranty, and one number to call.
Ongoing Service
Optional preventative maintenance keeps it running and catches wear before it becomes a shutdown.
Preventative Maintenance
We Keep You Ready for the People Who Count on You
A door that fails becomes an emergency call you have to explain. Scheduled maintenance catches the wear early, so it does not happen.
Peace of Mind
You stop watching the door. We are watching it for you, on a schedule.
Continuous Operation
Trucks keep moving and the building keeps running, with no surprise downtime.
Predictable Costs
Planned care and a set price, instead of emergency invoices you did not budget for.
