- Part 3 - Action plan to get started
What are the costs involved in opening a window installation and repair business?
Initial costs for opening this type of business can be relatively low. Licensing and insurance and tools and transportation are often the bulk of your costs. Much of your inventory will be ordered and delivered directly to your business or the job site, itself, eliminating a need for warehousing much product.
An average startup cost could range between $5,000- 10,000.
Some of the cost areas associated with a start-up:
-
Residential or commercial contractor’s license (check state and local requirements for your area)
-
Business insurance for yourself and any additional employees.
-
Certification courses for installs and repairs of certain company’s windows. These courses will vary, from company to company. It is also recommended that you seek national certification. Fenestration and Glazing Industry Alliance and American Window and Door Institute are great resources to get you started.
-
Tools and equipment for installation, basic construction and care and maintenance of windows and window parts.
-
Reliable transportation and ability to transport and deliver windows. A truck or panel van are reasonable options. Commercial auto insurance coverage may also be a strong consideration.
-
Office equipment, such as a desktop or laptop, printer/scanner/fax machine, and file cabinet, plus additional consumables.
What are the ongoing expenses for a window installation and repair business?
Maintenance for service vehicles and tools and related materials costs will be the bulk of your expenses. If you choose to rent office space or warehouse space, that will also be an additional cost.
Who is the target market?
Depending on if you choose to perform residential or commercial services, you will be targeting new construction and remodels within each sector. If you are able to become a sub-contractor for a larger building company or a window retail company, your target market may shift a bit to be more focused on the companies that are sub-contracting you. Overall, make sure you are always presenting a professional image for your business and services.
How does a window installation and repair business make money?
For each window replaced or newly installed, the customer is charged the price of the window and labor costs for installation. If working as a subcontractor for a window retailer as a repair specialist, the retailer’s warranty pays for your services, as well as the cost of the window for the consumer.
How much can you charge customers?
Depending on if you are charging the customer directly, or billing a window retailer or contractor for your services, you should be charging for the labor, transport of products, and additional fees for preventative maintenance and specialty work. Hourly rates range from $25-50 an hour. Make sure this is part of your initial market research to determine average fees in your area and overall numbers for ensuring profitability.
How much profit can a window installation and repair business make?
The national average for annual sales for a residential window business is $600,000. Earnings after taxes and business costs would average around $250,000-350,000, annually.
How can you make your business more profitable?
Offer customers a preventative maintenance service in which you regularly check window hardware, seals, and overall construction, as well as cleaning glass and servicing hinges, sashes, locks and related hardware. You may also consider a recycling and restoration service for older, hard to find sized windows. Being able to replace windows to match historical restoration specs can allow the window installer to charge considerably more than the average install.
Day-to-Day and Growth
What happens during a typical day at a window installation and repair business?
For most window installation and replacement businesses, day to day work revolves around estimations of damage and warranty coverage, actual window installation, customer service before and after the job is complete, devising and implementing business marketing techniques, and contacting new and potential customers, either through referral, customer contact via website or email, or direct service requests from authorized window retailers.
What are some skills and experiences that will help you build a successful window installation and repair business?
Having experience in retail sales of windows will give you great insight into the types of windows available on the market and will increase customer service ability by understanding what types of windows are available and for which applications. At the very least, you should attend seminars or classes on the brand, styles, or types of windows and installation techniques for the windows you are looking to install and replace.
Experience in construction is also a bonus, as you will need to understand the ins and outs of measuring and installing windows properly. A poorly done installation can nullify the effectiveness and, in some cases, the warranty of a window. Make sure you are regularly staying abreast of industry standards and policies for window installations and repairs.
What is the growth potential for a window installation and repair business?
Window installation and replacement is a profitable and steadily growing industry. With homebuilding on an upswing, the need for qualified and licensed window specialists continues to grow. Additionally, many consumers are looking to replace older windows for more energy efficient models, which ensures window installers have multiple growing aspects within their industry.
What are some insider tips for jump starting a window installation and repair business?
As with any start up, research the number of competitors in the area, determine your niche, and advertise accordingly. You have to know what kind and how much business you can anticipate and you have to make sure people know who you are. Window installation and repair can be a saturated market, so always test the waters to see what your best options are and follow those leads.
Connect yourself with other professionals in the area, both in your industry and in related industries, such as residential and commercial contractors, insurance providers, and window retailers. A large part of successful marketing grows from networking. Attending seminars, taking training courses, and connecting to industry associations, both in person and online, will allow you to drive your business in positive directions.
How and when to build a team
Initially, your business can grow and thrive with only one or two other employees, especially if you handle all paperwork and expenses internally. Two to three workers will be able to handle most installs and repairs. As your business grows, an office manager will be a critical addition to ensure orders, deliveries, job tickets, and all other aspects of a smooth running business are being carefully overseen. Additional field techs can be added, as business remains steady or is growing.

Part 3 - Action plan to launch your Window Installation and Repair business in 90 days
Nine concrete steps to take you from idea to open business, grouped into 30-day phases. Complete the planner above and we'll highlight what's most important for your situation.
First 30 days — Foundation
-
Form your legal entity
An LLC keeps your personal assets separate from business debts and lawsuits — the most common reason small business owners choose this structure. Sole proprietorships and partnerships do not provide this protection.
-
Get an EIN and register for taxes
Apply for your free Employer Identification Number through the IRS, then register for any state or local taxes that apply to your business (sales tax, franchise tax).
-
Open a business bank account and credit card
A dedicated business account is required to maintain personal asset protection. Mixing personal and business finances ('piercing the corporate veil') can void your LLC's liability shield.
-
Set up business accounting
Recording expenses and income from day one makes tax filing easier and lets you see when the business is actually profitable. Use software (QuickBooks, Wave) or a part-time bookkeeper.
Days 30–60 — Compliance & Risk
-
Get permits and licenses
State and local requirements vary widely. Brick-and-mortar businesses typically need a Certificate of Occupancy; service businesses may need specific professional licensing; food businesses need health permits.
-
Get business insurance
General Liability Insurance is the most common starting point. If you'll have employees, most states require Workers' Compensation. Specific industries need additional coverage (product liability, professional liability, etc.).
Days 60–90 — Launch
-
Define your brand
Your brand is how customers perceive and remember you. A clear name, logo, and visual identity make every later marketing decision easier and protect you legally as you grow.
-
Create your business website
Every legitimate business needs a website. Social media pages are not a substitute — you don't own the platform. Modern website builders mean you can launch a clean site in a weekend without a developer.
-
Set up your business phone system
A dedicated business number keeps your personal life private, makes the business look legitimate, and lets you route calls professionally. Cloud phone services start under $20/month.
