Getting Started

How to Launch Your Door Installation Business

Starting a door installation business is a straightforward path if you have basic carpentry skills, access to tools, and reliable transportation. Unlike many trades, you don’t need a storefront or inventory. Your business model is simple: measure, order, install, and collect payment. Most door installers charge $150–$400 per door installed, depending on door type and your market’s labor rates.

The key to launching quickly is handling the practical requirements first—licensing, insurance, and your first few customer connections—then scaling from there. You can start solo and add crew members as demand grows.

Your Step-by-Step Launch Plan

1. Check your local licensing requirements: Many states and counties require a general contractor license or a specific doors-and-windows installation license. Contact your state’s licensing board or local building department to confirm what applies in your area. This typically takes 2–4 weeks and may require a trade exam. Some areas have no licensing requirement for door installation; verify before spending time and money.
2. Register your business entity: Choose between a sole proprietorship (simplest, fastest) or an LLC (protects personal assets if someone is injured on your job). Filing an LLC takes 1–2 weeks and costs $50–$300 depending on your state. Use your state’s Secretary of State website or a service like LegalZoom or Northwest Registered Agent.
3. Obtain business insurance: Get general liability insurance ($300–$600 per year) and, if hiring employees, workers’ compensation insurance. Some customers—especially homebuilders and commercial property managers—won’t hire you without proof of coverage. Get quotes from 2–3 brokers before committing.
4. Set up your financial foundation: Open a separate business bank account. Choose accounting software like QuickBooks Self-Employed or Wave (free). If you’ll be invoicing customers, pick an invoicing tool. This takes one afternoon and clarifies your pricing and payment flow from day one.
5. Establish your pricing and service menu: Research what door installers in your area charge for entry doors, interior doors, patio doors, and storm doors. Create a simple price list or service menu. Include the cost of the door, your labor rate, and any removal or disposal fees. Write this down and keep it consistent across all quotes.
6. Build a customer acquisition plan: Identify your first customers. Start with referrals from friends and family, then contact local homebuilders, property management companies, contractors, and real estate agents. Create a basic one-page flyer or Google Business Profile listing your services, phone number, and rates. Spend your first two weeks making phone calls and networking locally.
7. Create a simple contract and quote template: Use a free Google Docs or Word template to build a one-page quote that lists the door type, size, materials, labor cost, timeline, and payment terms. Also create a simple contract customers sign before you start work. This protects both parties and clarifies expectations.
8. Invest in core tools and safety equipment: If you don’t already own them, buy a drill, impact driver, level, tape measure, square, and circular saw (around $300–$600 total for quality used or budget-friendly new options). Buy safety glasses, gloves, and a dust mask. Many installers work with standard carpentry tools rather than specialized equipment.

Your First Week

• Verify licensing requirements with your state/county building department; start the application process if needed.
• File your business entity (LLC or sole proprietorship) with your state.
• Get liability and workers’ compensation insurance quotes; select a broker and obtain a policy.
• Open a business bank account; set up basic accounting software.
• Research local door installation pricing; write down your price list.
• Create a simple quote template and one-page contract.
• Build a Google Business Profile with your phone, address, and service list.
• Make a list of 20 potential first customers: homebuilders, contractors, property managers, real estate agents, and friends/family.
• Call or email at least five of these prospects to introduce yourself.

Your First Month

Spend your first month acquiring your first 3–5 customers. Focus on outbound prospecting: phone calls, emails, and in-person visits to local contractors, builders, and property management offices. Deliver quality work on these early jobs so word-of-mouth referrals start flowing. Track every job—time spent, materials used, labor cost, and profit margin—so you understand your true unit economics.

By month’s end, you should have completed at least two full installations and have a second or third job lined up. Document your work with before-and-after photos; these become your portfolio and marketing material. Set a target of earning $1,200–$2,000 in revenue this month (roughly 3–5 doors at your regional rate).

Your First 3 Months

Your goal for the first quarter is to establish a rhythm: landing customers consistently, completing jobs on schedule, and building a reputation. Aim for 10–15 installations and total revenue of $2,000–$4,000 (assuming $150–$300 per door in labor plus material markups). By month three, you should have 5–10 repeat or referral customers so you’re not constantly cold-calling. You’ll also have enough data to refine your pricing, timeline estimates, and crew structure (solo versus needing help).

Track your customer satisfaction closely. Ask every customer for a Google review or referral. A door installation business thrives on reputation and word-of-mouth, so quality and reliability in these early months directly drive future revenue.

Legal Basics

Most door installation businesses start as sole proprietorships because they’re simple and require minimal paperwork. However, an LLC is worth considering if you’re handling customer money, working in homes, and want liability protection. The cost difference is small ($50–$300 in filing fees), and the legal protection for your personal assets can be valuable if a customer is injured or a door fails and causes damage.

Licensing varies by location. Some states require a general contractor license; others have no specific requirement for door installation. A few states require only a business license (cheap and fast). Start by calling your county building department and asking: “What license do I need to install doors in homes?” Your state’s contractor licensing board website will confirm. Many areas have no barriers to entry, which is why door installation is an accessible trade to start.

Insurance is non-negotiable. General liability covers property damage and bodily injury claims if someone is hurt or if your work damages their home. Most customers—especially homebuilders and commercial accounts—require proof of insurance before you start. Expect to pay $300–$600 per year for a $1 million general liability policy. If you hire employees, add workers’ compensation insurance (typically $15–$25 per $100 of payroll). See our legal resources page for state-by-state licensing specifics.

Common Launch Mistakes

• Starting without clarifying your state’s licensing requirements. You may launch, build clients, then discover you need a license and owe back fees. Verify first.
• Underpricing to land your first jobs. If you charge $100 per door when the market rate is $250, you’ll train customers to expect low prices and struggle to raise rates later. Price fairly from day one.
• Not separating business and personal finances. Mixing personal and business spending makes tax time a nightmare and hides your true profit. Open a business account immediately.
• Working without a written quote or contract. Verbal agreements lead to scope creep and payment disputes. Use a simple one-page quote and contract on every job.
• Skipping insurance to save money. One lawsuit or injury claim can wipe out your business and personal assets. Insurance is the cost of doing business professionally.
• Not documenting your work. Take before, during, and after photos of every installation. These become your marketing portfolio and proof of completed work if disputes arise.
• Trying to serve all door types at once. Start with the most common door type in your market (usually entry doors or interior doors) and expand once you’re efficient and profitable at that niche.
• Ignoring customer reviews and referral requests. Word-of-mouth is your main marketing channel. Ask every satisfied customer for a Google review or referral. This compounds over time.

Launching a door installation business is manageable when you handle the essentials first: licensing, insurance, and your pricing foundation. Then focus on landing your first few quality customers and building a reputation. Once you have a repeatable process and a pipeline of referral work, you can scale by hiring crews and expanding to adjacent services like trim or hardware installation.
