How To Choose a Window Company in El Cajon

With El Cajon's robust local economy, you're sure to find a reputable window company that suits your values and preferences. As you make calls, keep the following factors in mind:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with long life is important. Although high-quality windows may be more expensive to buy, they often provide better long-term value due to their longer lifespan. The material, size, and style of your new windows play the largest role in determining your final cost. 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. If you're undecided, a window specialist can help you figure out which options are most suitable for your home.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window TypesAverage Cost
Glass Block$46-$593

Window Material Cost

Materials also help determine a window's cost. You might choose a material based on the local climate, your energy efficiency goals, and your desired look. 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 TypesAverage Cost

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 factor in the cost of installation, guarantees, and any other extra expenses that your project may need.

Experience and Training

Examine a company's website and talk to a representative to learn more about its product and service offerings, pricing, and warranties. Many companies also keep online galleries that highlight past projects.

Ensure that the company specializes in window replacement. The more specific training its staff has, and the longer it has been in business, the more likely it will deliver excellent workmanship.

Licensing and Credentials

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

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's essential to find a company that specializes in the ones you want. Browse a company's website and reviews for any of these types:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Equally important to your desired windows' shape is their framing. Ask your window provider if it offers the frame material you want, such as wood, composite, fiberglass, vinyl, or aluminum.

Customer Feedback

Reading other customers' stories is one of the smartest ways to screen potential window companies. Trustworthy sources for customer reviews include 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.

Frequently Asked Questions About Window Replacement in El Cajon

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

El Cajon homeowners could potentially save $490 each year by switching to efficient windows. They'll also reduce their property's carbon dioxide emissions by 120 pounds per year.

According to the federal Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. Energy-efficient windows help keep heat out in the summertime and retain heat in the wintertime, improving your comfort and furthering your dollar.

How frequently should I upgrade or replace my windows?

Windows don't last forever, and most wood models are built to serve your home for 15–20 years. Over time, caulking and weatherstripping loosen, framing contracts and expands, and window coatings fade. These changes result in air leaks, energy loss, condensation, and other expensive problems necessitating repair or replacement.

My window screen tore. How should I fix it?

Most broken screens are very simple to fix. For small tears, some window installers might offer you a repair kit that use strong adhesive patches. If your installer doesn't include a kit, you can get one for about $5–$10 at a home supply store.

You might need to get a new screen for large tears or those along the edges of the window. A window service provider you trust can get the job done affordably.
