How To Choose a Window Company in Lake Forest

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

Window Cost by Type

When it comes to window replacement, value is king. Each window you buy should deliver unparalleled durability at a fair price point. Although top-of-the-line windows may come with a higher initial price tag, they often provide better long-term value due to their longer lifespan. The size, material, and style of your new windows have the greatest impact on your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. If you're undecided, a window provider can help you determine which options are most suitable for your home.

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

Window TypesAverage Cost
Glass Block$46-$584

Window Material Cost

Window prices also vary based on material. Each option provides unique advantages depending on the local climate and energy efficiency needs. Vinyl and fiberglass are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost

Other Window Replacement Costs

Your total cost for new windows will also include warranty fees (if applicable), permit application fees, and labor. Be sure to discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

Choose a provider that focuses on window installation and repair, and look for this information on its website:

  • How long it's been in business
  • Photo galleries of completed projects
  • Privately-issued certificates attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

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

Types of Windows Offered

No two businesses offer the same window designs and materials. Look for one that focuses on 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 kind of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include wood, fiberglass, aluminum, composite and vinyl.

Customer Feedback

One of the best ways to evaluate a company is to see what other customers have said about their experiences. Read customer reviews on sites such as Yelp, Trustpilot, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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.

Frequently Asked Questions About Window Replacement in Lake Forest

How much energy and money will I save by upgrading my windows?

In Lake Forest specifically, most homeowners using efficient windows reduce their carbon emissions by 120 pounds each year. That amounts to $390 of annual savings.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By investing in new, more efficient windows, you can enhance your home's energy efficiency and reduce your electricity bills.

How can I fix a rotting or molding window frame?

A window frame with mold or rot is usually a moisture issue. You likely won't have to replace the entire window. Instead, a simple framing job could do. It's best to consult a window expert to ensure correct sealing and weatherproofing.

How can I fix a broken window screen?

It depends on the tear size and its location on your window. You can usually address small tears yourself using a special kit. Some window providers will supply you with one when they set up your windows, or you can buy one for $5–10 from a local hardware store. Larger tears, or those located at the edge of a window, usually need expert help.
