Professional wallpaper installation for homes that deserve better than plain paint. Accent walls, full rooms, powder rooms, ceilings - measured, prepped, and hung right.
You get the same standard on every job and a written scope before any paper goes up - whether it's an accent wall or a whole house.
The fastest transformation in home improvement. One wall, one day, a whole new room.
Dining rooms, bedrooms, nurseries, home offices - measured and hung to the pattern, corner to corner.
Small rooms with the biggest personality. Moisture-aware prep and flawless tight-space work.
Wallpapered ceilings are the design move nobody expects. Delicate work, done carefully, overhead.
The jobs other installers decline. Angles, height, and pattern control - handled.
Traditional paste-the-paper, paste-the-wall non-wovens, grasscloth, and peel-and-stick. Client-supplied paper or sourced for you.
Wallpaper magnifies everything underneath it. Every surface gets evaluated before a quote - and where walls need skim coating or wallpaper primer, it's on the estimate as its own line. No surprises, no shortcuts underneath your paper.
Drop matches, straight matches, half-drops - the label math decides how your room is cut, and it's the first thing checked on walkthrough. The pattern meets at every seam, or the job isn't done.
Free on-site measure. Itemized quote within 24 hours - labor, prep, and materials laid out in plain English.
Walls cleaned, patched, skimmed where needed, and sealed with wallpaper primer so adhesive cures right.
Plumb lines before a single strip goes up. Pattern matched seam to seam, trimmed clean at every edge.
Every seam, edge, and corner gets a final inspection before the tools are packed - backed by a written 90-day workmanship warranty.
A lookbook of styles and spaces we install - from first accent wall to full-room statements.
True Line Wall Co is a wallpaper installation company based in Westerville, Ohio, owned and led by Darrel Grumman.
I spent twenty years running operations before I ever hung a strip of paper commercially - managing teams, schedules, and standards where "close enough" wasn't. I brought that same discipline to this trade: every wall plumb-checked, every seam matched, every job documented from bare wall to final trim.
This is an owner-led company, and it's built to grow. Whether the work is done by me or by an installer trained to my standard, the rules don't change: estimates in writing, prep itemized honestly, a written workmanship warranty behind every job. If a wall can't hold paper properly, we'll tell you before we quote it, not after we hang it.
