Treasure Valley Flooring Costs
How Much Does New Flooring Cost in Nampa & Boise?
Flooring costs in the Treasure Valley vary significantly by material. LVP (luxury vinyl plank) — the most popular choice for Idaho homes — typically runs $4–$8.50 per square foot installed, including materials and labor.
Hardwood commands a premium at $9–$20 per square foot installed, while laminate and carpet remain the most budget-friendly options at $3–$7.50. Tile work varies the most — basic ceramic is affordable, but large-format or porcelain can push $15+ per square foot.
The estimator below uses these local rate ranges. Enter your room dimensions and get a realistic ballpark in seconds — then reach out for a firm quote.

What Makes These Estimates Accurate?
These aren't national averages pulled from a database. They're built from real project pricing by a licensed GC operating in Nampa, Meridian, Boise, and the surrounding Treasure Valley — updated for 2025 material and labor costs.
Local Labor Rates
Labor costs in the Treasure Valley differ from national averages. These ranges reflect what licensed local contractors charge in 2025.
Material Grade Ranges
Each flooring type has a low-to-high range reflecting entry-level vs. premium materials — so you can plan for your budget.
Waste Factor Built In
Flooring always requires extra material for cuts, mistakes, and future repairs. The estimator factors this in so you order the right amount.
Room-by-Room Accuracy
The full estimators support multiple rooms — living room, bedrooms, hallways — for a whole-home project total.
Paint Coverage Formula
The painting estimator uses the standard 350 sq ft per gallon coverage rate and deducts doors and windows from your wall area automatically.

Treasure Valley Painting Costs
How Much Does Interior Painting Cost in Nampa & Boise?
Interior painting in the Treasure Valley typically costs $1.50–$3.50 per square foot of wall area for labor alone. Add materials — paint, primer, tape, and supplies — and a standard room runs $350–$900 depending on size, finish type, and condition of the walls.
Ceilings add roughly $150–$400 per room. Trim and baseboards are quoted separately at $0.80–$1.80 per linear foot. Paint finish matters too: flat and eggshell are the most forgiving, while semi-gloss and satin are more washable — ideal for kitchens, bathrooms, and high-traffic spaces.

Open Calculator →Built by a Working Contractor, for Contractors Who Price Their Own Jobs
These tools came out of real frustration. After years in the field, we saw too many skilled tradespeople walking away from jobs with nothing to show for it because they priced on gut feel instead of actual numbers.
Markup and margin are not the same thing. A 50% markup is only a 33% margin. If you mix them up, you quietly lose money on every job. The Markup Calculator was built specifically to make that distinction clear.
The Profit Calculator goes further: enter your real costs including your overhead share, the price you plan to quote, and your target margin. It tells you whether the job makes money before you commit to it.
Overhead Is Not Optional
Insurance, truck payments, tools, and slow weeks all cost money. If your quote does not account for overhead, the job is subsidizing your business.
Margin vs Markup
Margin is figured on your selling price. Markup is figured on cost. Confusing them is one of the most common ways contractors underprice their work.
Know Before You Quote
The best time to fix a bad price is before you give it. Running the numbers takes two minutes and can save you from locking into a money-losing job.
Why contractors stay broke
Every Contractor Without a System Loses Money the Same Three Ways
It is not about working harder. Skilled tradespeople leave money behind every week because the pricing and paperwork side runs on guesswork. These three patterns are where the money goes.
Bidding from gut feel
You finish a job and realize you left $400 on the table — or worse, you won a bid that cost you money. Gut feel has a price, and most contractors pay it for years before they track it.
Rebuilding estimates from scratch
Every new quote starts with a blank page. You re-type line items, redo the math, recalculate tax. Those are unpaid hours every single week.
No paper trail when it goes sideways
Client says "that wasn't in the scope." You have no signed estimate, no payment terms on paper. Now it's a dispute instead of a done job.
