2. Contact your local building department or licensing agency to find out what licenses are required to operate in your city. You may need to obtain a home improvement contractor license, a construction supervisor license, or obtain lead safe certification through the Environmental Protection Agency’s Renovation, Repair and Painting Rule.

3. Acquire a commercial vehicle. Then fill it out with business information, such as whether you are certified, licensed, insured, and obligated to post a bond. Include your site URL and phone number.

4. Be legal. Contact your current insurance provider about purchasing business insurance and commercial auto coverage. If the insurer can’t provide you with a policy, they should be able to connect you with someone who can. Buy a contractor’s surety bond from a surety company. This assures your clients that in the event that you are unable to complete the job, they are covered. It may also be necessary when bidding on government contracts.

Find reputable window suppliers who offer a variety of replacement windows, such as vinyl, fiberglass, double pane, thermal, paneling, aluminum siding, garden, landscaping, window boxes, and custom windows, as well as glass and grid options. Obtain samples and develop a portfolio to show clients.

How to set prices to start a window installation business

Demand in the window industry has been strong for centuries, as windows are necessary in the construction of almost any type of building, regardless of its purpose. Starting a showcase business can be an exciting opportunity to join this strong industry, although it can be challenging for new investors to gain market share. Pricing is an important element of your marketing mix that can set your window business apart from the pack.

Competitor prices

Looking at the existing pricing structures of the window business can be a good starting point when setting your own prices. Avoid making the mistake of simply sifting through your competitors’ prices and setting yours a little lower. This can trigger a price war that your established competitors may be more equipped to survive than you are. Rather, use your pricing models as a basis to get an idea of ​​the general range in which your own prices should be.

Cost-based pricing

Your costs can also serve as a solid starting point in forming your pricing strategies. Consider the cost of materials, labor, and overhead, as well as your desired profit margin, to set prices based on your cost structure. Cost-based pricing can help establish an image for your business and brand in the marketplace, as higher-quality products generally carry higher costs, resulting in higher prices and a feeling of superior quality.

Volume pricing

Consider offering different price tiers for higher volume purchases, or negotiating individual prices based on volume contracts. Selling 2,000 windows to a large company at a 20 percent margin, for example, can be much more profitable than selling two windows to a consumer at a 50 percent margin. Offer fixed-term price discount contracts to construction companies that also need a regular supply of long-term windows.

Promotional prices

After determining your optimal pricing structure, consider offering temporary discounts to bring your business to market, or to introduce new window models in the future. Offer big discounts for new models to any customer you have volume pricing contracts with to help promote your new product lines to your most loyal customers.
