How To Choose a Window Company in San Luis Obispo

It's crucial to find a window installer that meets your individual values, needs, and preferences. Consider the following points during your search:

Window Cost by Type

When you're shopping for new windows, it's essential to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Choosing economy windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The age of your home, together with the styles, materials, and sizes of windows you choose, can affect pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. A professional can help you with choosing the options that fit your preferences.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window Types Average Cost
Arched $238-$1462
Awning $344-$960
Bay $794-$5892
Custom $353-$982
Casement $274-$1593
Double-hung $128-$829
Egress $235-$588
Glass Block $47-$596
Picture $206-$1527
Single-hung $93-$1571
Skylight $117-$1418
Sliding $270-$1374
Storm $55-$388
Transom $288-$602

Window Material Cost

Materials also help determine a window's cost. You might select a material based on the local climate, your desired look, and your energy efficiency goals. For example, wood windows can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

Window Types Average Cost
Aluminum $55-$1571
Composite $567-$1274
Fiberglass $93-$794
Vinyl $191-$1767
Wood $283-$1593

Other Window Replacement Costs

Ask each contractor you're evaluating about warranty fees, labor costs, and permit fees. This will help you gain a complete understanding of the financial commitment involved in the project.

Experience and Training

The longer a window installer has served your area, the better its workmanship will likely be. Call a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often keep photo galleries showcasing previous work technicians have done.

Licensing and Credentials

A California window company must be licensed as a Window Coverings Contractor, General Building Contractor and Glazing Contractor if it handles jobs valued at over $500. Each certification has its own exam and experience requirements. If a contractor is caught working without a license, they'll have to pay steep fines.

Types of Windows Offered

No two contractors offer the same window types and materials. Look for one that's an expert in the type you want for your home.

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Also, check the type of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include vinyl, fiberglass, aluminum, wood and composite.

Customer Feedback

One of the greatest ways to vet a company is to read what other customers have written about their experiences. Read customer reviews on sites such as Google, Yelp, and Trustpilot. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Talk to people you know who have used the company you'd like to hire, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in San Luis Obispo

Why should I hire a professional to install or replace my windows?

Replacing your windows is a big investment that greatly impacts your home's livability and energy efficiency. Hiring a skilled window installer to oversee your project ensures your windows will be properly installed, perform efficiently, and be properly insulated. Companies also typically include a guarantee that takes care of required maintenance and most needed fixes.

I've heard there are tax credits for energy-efficient windows. How much could I save?

Yes. No matter where you're located, you can claim a federal tax credit of up to $3,200 per year on up to 30% of your window replacement's cost. Further, most state and some local governments offer financial incentives of their own. We recommend checking with your local energy department for specific information about tax incentives available in your area.

I broke my window's glass. Could I replace just the glass?

If your window has a cracked pane, it might not be required to replace the entire frame. Usually, only the glass needs to be repaired unless the frame has also taken extensive damage. A professional can determine exactly what's necessary during an estimate visit.
