The real steps. Licensing, pricing, finding clients, and the tools you need.
No fluff. No "believe in yourself" filler. Just what to actually do.
Starting a window installer business takes $500-5,000 in startup costs, proper licensing for your state, and business tools (invoicing, scheduling, CRM, bookkeeping). The median window installer earns $55,000/year. Most new window installers make the mistake of renting $100-200/month in software subscriptions from day one — that is $1,200-2,400/year before you have a single client. Nexa is $279 once for all of it. Biz Wiz ($19.99) builds you a personalized plan with your state's exact licensing requirements, pricing research for your area, and a 90-day action checklist.
Median income for window installers. Top earners make significantly more.
Your income = your pricing × your volume × (keeping overhead low).
Every state is different. You may need a business license, trade-specific license, insurance, or permits. Don't skip this — getting caught without proper licensing can cost more than the license itself. Check your state's requirements →
Research what window installers charge in your area. Don't underprice to "get started" — you'll burn out. Price for profit from day one. Most window installers charge based on job size, complexity, or hourly rate.
You need: Pry bar, oscillating multi-tool, demolition saw, Window-buck shim shop (cedar, plastic), Caulk gun and tubes (silicone, polyurethane), Tape measure, levels, plumb bob, Lift table (for large picture windows), Their van with material rack. Buy quality — you'll use these every day. This is a real investment, not a subscription you're renting. Own your tools from the start.
You need invoicing, scheduling, client tracking, and bookkeeping. Most window installers pay $100-200/month renting these from 3-4 different companies. Or you can get Nexa — all of it for $279 once. You own it. See what the subscriptions really cost →
Start with people you know. Post on Nextdoor. Join local Facebook groups. Tell everyone what you do. Your first 5 clients become your first 5 reviews — and reviews are everything in this business.
Set a weekly schedule: when you work, when you do admin, when you market. Track your hours. Send invoices same day. Review your finances monthly. The window installers who build a rhythm survive. The ones who wing it don't.
Sound familiar? That's what happens when your tools don't talk to each other. Nexa connects everything — log a job, invoice from it, track the payment, update your books. One app. $279 once.
Biz Wiz ($19.99) builds a plan around YOUR specific problems — not generic business advice.
Here's what window installers actually say about the tools they use:
These are real frustrations from real window installers. Nexa was built specifically for solo operators — not enterprise teams, not agencies. $279 once. Or $99 today and two more payments.
Everything you need to go from idea to open:
Everyone talks about equipment costs. Nobody talks about the software tax.
Most window installers end up paying $100-200/month for business software — invoicing, scheduling, bookkeeping, client management. That's $1,200-2,400/year. Over 5 years with price increases: $8,000-15,000. For tools you don't even own.
Nexa: $279. Once. Invoicing, scheduling, CRM, task management, and full QuickBooks-style accounting. You own it like you own your Pry bar, oscillating multi-tool, demolition saw.
Depends on equipment and licensing. Typically $500-5,000 to start. The biggest ongoing cost is software subscriptions ($100-200/month) — which Nexa eliminates with a $279 one-time purchase.
Varies by state. Biz Wiz ($19.99) researches your specific state's requirements and includes them in your personalized plan.
Start local: Nextdoor, Facebook groups, word of mouth. Get 5 clients, get 5 reviews. Reviews compound. Your plan from Biz Wiz includes a marketing strategy tuned to your area.
