How To Choose a Window Company in San Marcos

Each window provider has specialized offerings and approaches. To streamline the company search, keep these factors in mind:

Window Cost by Type

Replacing your windows is a significant investment, so balancing cost with performance is crucial. Choosing cheap windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The style, size, and material of your new windows have the greatest impact on your final cost. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. If you're unsure, a window provider can help you decide which options are ideal for your home.

This table shows average prices for various window types to give you an idea of what to expect.

Window Types Average Cost
Arched $220-$1355
Awning $319-$890
Bay $736-$5462
Custom $327-$910
Casement $254-$1476
Double-hung $118-$768
Egress $218-$545
Glass Block $43-$552
Picture $191-$1416
Single-hung $86-$1456
Skylight $109-$1314
Sliding $250-$1274
Storm $51-$360
Transom $267-$558

Window Material Cost

You'll also need to pick a window material. Homeowners frequently make their selection by considering aesthetic preferences, energy efficiency objectives and the local climate. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less up-front, but you'll need to invest in regular maintenance to prevent the frame from wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window Types Average Cost
Aluminum $51-$1456
Composite $525-$1181
Fiberglass $86-$736
Vinyl $177-$1638
Wood $262-$1476

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to take into account the cost of labor, warranties, and any other supplemental fees that your project may need.

Experience and Training

Peruse a company's website and chat with a representative to learn more about its product and service offerings, pricing, and guarantees. Many companies also keep online portfolios that highlight past projects.

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been in business, the more likely it will provide top-notch service.

Licensing and Credentials

To install windows in the Lone Star State, all a contractor must do is enroll with the Secretary of State. Some cities, most notably San Antonio, require service providers to carry liability insurance and pass a background check. Dallas and Fort Worth require contractors to register with the city, and Houston does not require licenses or registrations at all.

Types of Windows Offered

The style of window you want should influence your company choice. Not every contractor will necessarily be familiar with the types you want. A company website will tell more about the styles of windows it specializes in, such as:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the framing materials that an installer uses. Each frame material has a different energy efficiency level, life span and price point. A company will usually specify whether the windows they place use composite, wood, vinyl, metal, or fiberglass.

Customer Feedback

One of the most surefire ways to evaluate a company is to read what other customers have written about their experiences. You can find customer reviews on websites like Trustpilot, Yelp, the BBB, and Google. Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

Frequently Asked Questions About Window Replacement in San Marcos

What are the benefits of hiring a window installer?

Replacing your windows is a substantial purchase that greatly impacts your home's comfort and energy efficiency. Hiring a professional window company to manage your project ensures your windows will fit correctly, operate effectively, and be properly insulated. Companies also typically include a guarantee that takes care of required maintenance and most needed fixes.

Do I need a building permit to replace my home's windows?

Whether you need a building permit to replace your windows varies on your local building codes and regulations. Some towns require permits for window replacement projects, especially those involving structural changes or alterations to the window openings. We recommend checking with your local building department or contact a professional before proceeding with any window replacement work.

How important are guarantees and extended support packages?

Window companies often offer assurances for the work they do. Each typically covers defects with workmanship and materials for a specified period of time. It's essential to check the conditions of the warranty with a window company before working with it.
