Installing trim yourself is a rewarding DIY project that saves thousands in labor costs. Use NailIt to estimate exactly what materials you'll need and budget accordingly. Our calculator covers lumber, fasteners, finishes, and tools for your next trim project.
Estimated DIY materials cost for total materials for one room (average 200–300 linear feet of trim) — you supply the labor. Prices vary by region and brand.
Across the full range this works out to $2.83–$18 per linear ft, depending on material grade and how much waste you plan for.
Here is the arithmetic, so you can redo it with your own numbers: a typical project here is 200–300 linear ft and runs $850–$3,500 in materials. Divide the middle of that cost range by the middle of the area range ($1,800 ÷ 250 linear ft) and you get $7.20 per linear ft. Measure your own space, multiply, and you have your materials budget.
Materials only — labour is not included. See what a contractor charges below.
A handy DIYer can usually take this on; if it needs permits or systems you are unsure about, get a pro quote first. The pro figure is a rough rule of thumb (labor on jobs like this often runs 1–2.5× the materials) — always get real quotes. It is not a NailIt estimate.
NailIt estimates materials only, so here is the honest version of the labour question rather than a number we cannot stand behind. Installed, this job commonly lands somewhere around $1,700–$12,250 — that is the materials range above with labour applied at the rough 1–2.5× multiplier trades typically work to on jobs like this. It is a sanity check for reading a quote, not a NailIt estimate and not a substitute for a real one.
What actually moves that number: your region and local labour rates, access and prep work, whether a permit and inspection are involved, disposal of the old material, and how much the crew has to work around your schedule. For this project the DIY route is realistic for most homeowners, and the labour saving is the whole point. Always collect three written quotes from licensed, insured contractors and compare what each one includes — how we handle pricing.

All materials you purchase: trim lumber, fasteners, caulk, filler, primer, paint, and abrasives. Labor and installation are not included—you're doing the work yourself.
Measure the linear feet of walls where trim will go. Average room trim runs 200–400 linear feet. Account for door frames, window casings, and baseboard. Add 10% for waste and mistakes.
Basic hand tools (miter saw, nail gun, level, tape measure) are typically already owned by DIYers. If renting, rental costs are separate from materials; NailIt covers materials only.
