How long does it take to install a new window?
Most installations can be completed in just one day.
How long have you been in business?
California Energy Contractors has been serving Southern California in the art of window and door replacement since 1999.
Are your installers certified?
Not only does California Energy Contractors hold a valid B-General Building Contractor License, we are also Atrium Certified, which is the highest certification by Atrium and part of the “By the Book” methodology. Most other window installers hold only a C-17 license, which is nothing more than a glazing license.
How will replacing my windows save me money?
The truth is, poorly designed and improperly installed or deteriorated windows can be the biggest single cause of energy loss in the home. They can also, therefore, be the biggest opportunity to save energy. Many of our customers have reported a savings of up to 30% off their utility bills after replacing their old windows with any or our Window Products!
How will replacing my doors and windows improve the comfort of my home?
Any of our Window and Doors will give you a quieter home, improve homeowner safety, and improve security. Several of our glass options will also help to lock out heat and glare in the summer and lock in heat during the winter, as well as help protect your furnishings from the bleaching rays of the sun.
If I decide to sell my home, will new windows and doors increase the value?
It certainly will. Your investment in windows and doors is one of the best home improvements you can make. In fact, Realtors across the country report that homes with new energy-efficient, maintenance-free windows enjoy a return of up to 114% in resale value!
What happens if someone gets hurt while working on a job on my property?
Each and every one of our workers is completely covered under our company’s $1,000,000 worker’s compensation policy. You are not at risk of damages whether your homeowner’s insurance covers you or not. Ask your California Energy consultant to show you a copy of this policy.
How do I know that I’ll be taken care of after the installation?
One of the beauties of California Energy Contractors is that we have a full time service department dedicated to providing our customers with remarkable customer assistance beyond initial installation.
How long does it take from the time I order to the time of installation?
Depending on your custom features 4-10 weeks
I don't know if I can afford to pay for my new windows or doors all at once, do you offer financing?
We sure do. We offer financing with competitive interest rates that our salespeople would love to tell you about when visiting you in your home. Just ask!
Do you have references in my area?
Yes. We have many references available in various areas of Southern California. All of the pictures on our website are of actual installations we have completed. If you would like to see our work in person please make sure to tell us what city you would like the references to be in.
How long will it take for our installation to be completed?
The length of time depends on each situation and the number of windows and/or doors we’ll be installing. Our installation crews are the cleanest, most professional, knowledgeable, and efficient installers in the industry. The quality and care we take is unsurpassed. An average home can take as little as a day with a crew consisting of 2-4 men. Other companies could take up to two days due to lack of experience, knowledge, and expertise. Our goal is to not inconvenience our homeowners and to offer the highest quality available.
What type of warranty do you offer on the windows and on your installation?
All products California Energy Contractors sell carry a lifetime limited warranty from the manufacturers. and a full three year warranty on our labor.
How many years of experience do you have?

What happens in the event of rain?
We will reschedule your installation. There are many hazards when working in the rain with vinyl, glass, and electrical tools. We cannot guarantee that you will be re-scheduled for the next available dry day, but you will be given top priority. During the rainy season we constantly check the weather forecast in order to give homeowners as much advance warning as possible.
I work and cannot be home during the week, do you install on Saturdays?
Yes we do. We try to let or homeowners know that they will have a better chance of getting an install date within 4-8 weeks of ordering however, if they’re scheduled during the week. We recommend arranging for a relative or friend to be present at your home that day rather than waiting for an available Saturday. They book up quickly!
What is Low E glass and how does it work?
Low E stands for low emissitivity. It is a technologically advanced glass that utilizes a microscopic coating to reflect heat and block ultraviolet rays.
Why do some vinyl windows yellow over time?
One major factor in vinyl integrity is whether or not a window is made of only virgin vinyl. Some manufacturers will heat up the vinyl resin to extrude a window frame and once the frame has been cut will remelt the scraps to extrude again. This compromises the vinyl integrity. Each time the vinyl is reheated at such extreme temperatures it becomes weaker and therefore susceptible to UV infiltration. Another major factor is whether or not the window manufacturer includes titanium dioxide in the vinyl. Titanium dioxide strengthens the vinyl to protect from UV infiltration.
Why should I buy my windows through a dealer such as yourself, when some manufacturers allow me, the consumer, to buy directly from them?
When it comes to manufacturers there can be a world of difference between one company and the next. You should be aware of small companies that sell directly to consumers because they aren’t subject to all the same regulations that larger manufacturers are. Smaller companies are less likely to be around for the warranty that they offer.
Why does condensation occur?
Condensation (water vapor or moisture in the air) is a sign of excess humidity inside the home. Condensation occurs when moist air comes in contact with the colder surface, such as a window or mirror. Although the surface of a window may be the first place you notice condensation forming, the window is not the problem. Windows, in this case, merely provide a visible sign that excess humidity or moisture is present in the house.
Warm air holds more moisture than cool air. When that warm, moist air comes in contact with a cooler surface, the moisture suspended in the warm air transfers to the cooler surface as condensation.
What causes moisture inside the home?
Indoor moisture in the air is caused by a variety of factors. Common household activities such as cooking, showering, using the washing machine or dishwasher and other activities that use hot water all add moisture to the air. Newer homes are often more subject to condensation because they are constructed with better weather tight materials than older homes. Weather stripping, improved insulation, vapor barriers and modern construction techniques are designed to reduce air leakage. But at the same time, these materials and techniques can also seal moisture inside the home. In newer, more weather tight homes, it is important to be aware of humidity levels and to provide adequate ventilation to reduce humidity levels.
What is a U-factor?
The U-factor is a measure of heat flow or conductivity through a material, the reciprocal of R-value. Although R-values are used as for measures of the resistance to heat flow for individual building materials, U-factor is always used to measure the conductive energy of building enclosures.
What is a Design Pressure Rating?
Design pressure, or also referred to as DP, expresses a numerical value that defines the structural wind loading requirements (in pounds per square foot) for a building and the components and cladding of a building. For windows and patio doors, the higher the DP rating indicates better performance under wind load (eg: a DP-50 window is structurally more sound than a window rated DP-35). Coastal regions often require higher DP ratings by code to anticipate higher wind velocities that can be encountered in proximity to the coast line.
What is meant by “Solar Heat Gain Coefficient” (or, sometimes expressed as “SHGC”)?
The number to know when selecting windows and patio doors – it measures how much of the sun’s heat is transmitted through these fixtures, expressed in a number from zero to one. A window that has a SHGC of .30 will allow 30 percent of the sun’s heat to pass through. Whether you want a higher or lower number will depend on your goal. Especially in the South, you will be primarily interested in a window or patio door with a low SHGC that will help to block solar heat gain inside your home, thus reducing cooling loads in hot weather. Northern climates often look for higher SHGC performance to harness passive solar warmth on cold, sunny winter days.
What is insulated glass?
Insulated glass consists of two pieces of glass hermetically sealed to a spacer. This creates a sealed, insulated air space between the two pieces of glass, resulting in better thermal insulation performance. Insulated glass also helps reduce condensation while keeping the heat in during the winter, and heat out during the summer.
What is low-E glass?
Low-E stands for low-emissivity glass – this is a nearly invisible coating on the glass surface that are microscopically thin metallic oxide layers primarily to reduce the U-factor by suppressing radiative heat flow. The principal mechanism of heat transfer in multilayer glazing is thermal radiation from a warm pane of glass to a cooler pane. Coating a glass surface with a low-emittance material and facing that coating into the gap between the glass layers blocks a significant amount of this radiant heat transfer, thus lowering the total heat flow through the window. Low-E coatings are nearly transparent to visible light. Our primary glass supplier, Cardinal Glass, offers informative details on their website:
What is argon gas? How does it work?
Added inside an insulated glass unit air space, argon gas is an invisible, insulating gas with lower thermal conductivity than atmospheric air. During the manufacturing process, the atmospheric air is displaced when argon gas is pumped into the glass unit airspace. When combined with Low-E glass the Low-E glass helps reflect heat away, while the argon gas helps reduce thermal transfer to enhance the glass unit insulating performance.
What is the Energy Star® program?
