How To Choose a Window Company in Altadena

Trustworthiness is essential when it comes to choosing a window installer. However, your chosen company should also match your priorities and respect your vision. Think about the following factors during your company search:

Window Cost by Type

Replacing your windows is a major purchase, so balancing cost with quality is important. Choosing budget windows could actually raise your overall cost, due to their shorter lifespan and more intensive maintenance needs. The age of your home, in addition to the materials, sizes, and styles of replacement windows you opt for, can influence pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. It's advisable to consult a trusted window installer to decide on your best options.

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

Window TypesAverage Cost
Arched$244-$1,495
Awning$353-$982
Bay$812-$6,026
Custom$362-$1,004
Casement$281-$1,629
Double-hung$131-$848
Egress$241-$602
Glass Block$48-$610
Picture$212-$1,562
Single-hung$96-$1,607
Skylight$121-$1,451
Sliding$277-$1,406
Storm$57-$397
Transom$295-$616

Window Material Cost

You'll also need to pick a window material. Homeowners usually base their decision on aesthetic preferences, energy efficiency objectives and the local climate. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows 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 TypesAverage Cost
Aluminum$57-$1,607
Composite$580-$1,303
Fiberglass$96-$812
Vinyl$196-$1,808
Wood$290-$1,629

Other Window Replacement Costs

Ask each window installer you're considering about labor costs, warranty fees, and permit fees. This will help you gain a complete understanding of the total costs involved in the project.

Experience and Training

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

Licensing and Credentials

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

Types of Windows Offered

There are several replacement window types you can choose from, and it's important to find a company that has expertise with the ones you want. Browse a company's website and reviews for any of these types:

Also, check the style of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include wood, fiberglass, composite, vinyl and aluminum.

Customer Feedback

Reading other customers' stories is one of the smartest ways to screen potential window companies. You can find customer reviews on websites like Trustpilot, Yelp, the BBB, and Google. Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.
