  • What To Ask References
    Questions for References of Skylight Companies in the San Francisco

    It's best to choose a Diamond Certified skylight company because all certified companies have passed an in-depth ratings process that most other companies can't pass. If you want quality from a skylight in San Francisco and the greater Bay Area, including the major neighborhoods of Hayward, Berkeley, San Leandro, and Alameda, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you'll never be fooled by fake reviews. That's because all research is performed in live telephone interviews of actual customers.

    If you can't find a Diamond Certified skylight company within reach, you'll have to do some research on your own. If you do, it's wise to call some references provided by your skylight company. Keep in mind, though, that references provided to you by the skylight company are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That's because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the local skylight company's ten most recent customers. This will help avoid them giving you the names of only customers they know were satisfied. Ask general questions about their experiences with the company's personnel, as well as questions about the installation. Questions you might want to ask include:

    • What type of skylights do the _ (name the skylight company_) install for you?
    • Were you satisfied with the skylight installed from this San Francisco skylight company?
    • Did the skylight company finish their work on time?
    • Did the skylight company keep you up-to-date with the status of the skylight? Or did you have to call in order to get information?
    • If you live in a smaller neighborhoods, such as Cole Valley, and Noe Valley, did they charge extra to travel to your home?
    • Did the company show up on time?
    • Did you feel the price was fair for the skylight?
    • Did they clean up after completing the job?
    • What did you like best about this particular skylight company?
    • If you need a skylight in the future, will you consider hiring this skylight company?
    • Would you recommend this skylight company to your friends and family?

  • How To Work With
    Getting the Most Benefit from Skylight Companies in San Fran

    Once you find a local skylight company that meets all your standards, it is time to ask for a written contract. This contract should include the written details about the price of the skylight and the installation, as well as the dates to begin and end the job.

    Be sure to read and understand all the terms and restrictions before you sign the contract. This contract should protect your property and your interests, as well as those of skylight company. Because of this, you should never sign an incomplete estimate.

    Do not be afraid to write specific requests or verbal agreements in the contract. This will protect you and confirm that you get the services you agreed on. You might include issues that are not always in a contract, like roof or lawn damage from installing the skylight.

    Also protect your home by being proactive. Before the skylight is installed, schedule a walk through with the company supervisor and conduct a pre-work inspection of the property. You may want to take pictures of the home and landscape where the company will be working. Speak to the representative about the protection of your roof and yard during the work. After reaching an agreement, both you and the representative should sign and the date the contract. After the skylight is installed, do a final inspection together to confirm that your expectations were met.

    Prepare Your Home for Skylight Installation
    There are some things you can do to prepare for the skylight installers arrival and while the work is in progress to help their job go more efficiently. You could cut back on billable hour or the possibility of damage to your home.

    Remove furniture and other movable objects from the working area. Before the workers arrive, remove all furniture, and movable items from the room where the skylight will be installed. Anything you can't remove should be moved as far out of the way as possible an covered with drop cloths.
    Provide parking space for the work vehicles. Some skylight companies have large work trucks and may need more parking space than the regular vehicles. Communicate with the company before the start date and ask them how many vehicles will need parking space and whether any of the vehicles is oversized.

    Keep children and pets away from the work area. The contractors will be concentrated on their work and should not have to watch out for children or pets. Rope off the room that is being worked on and keep that area clear until the work is finished.

Bathroom, Pantries, Laundry Room, Hallway, Walk-in Closet
13/14 Inch Skylight- 150 -250 sq. feet.
Kitchen, Foyer, Garage,  Living Room, Family Room

18 Inch Skylight- 300 – 500 sq. feet.
Room with a vaulted ceiling, Great Room, Garage, Family Room, Living Room

21 Inch skylight- 500 – 700 sq. feet
Only for Commercial Flat Roof Application

Q: Is it important where you place the skylight on the roof?
A: The best location is normally on the southwest facing side of the home. You must  take into consideration a chimneys or adjoining roof structures or even trees – things that can put a shadow over the dome will to effect how much light goes in. They also can work well on the north side of the house.  Always remember that the best light output is gained by exposing the skylight to direct sunlight.

Q: How long can sunlight tubes be?
A: The ideal length of tube is approximately 6 feet. Lengths over 15 feet are routinely installed with very good results. The unit to the next size for runs that are longer than 14 feet.

Q: What is the difference between acrylic plastic and Plexiglas?
A:There is no difference. Plexiglas is a brand name for acrylic plastic.  Lucite is another popular brand name.

Q: What is the difference between tempered glass and laminated glass?
A: Tempered glass is glass strengthened by heat like the glass used in shower doors and patio doors. It is a very strong glass, but, when it breaks, it will explode into hundreds of tiny pieces. Tempered glass is also usually used in the side windows of your car.

Laminated glass is glass that has a plastic interlayer.  This layer is designed to hold in place when it breaks. Another type of laminated glass is the front windshield of cars. Another advantage of using laminated glass is that is a very effective block against ultraviolet light.  UV light is the leading root of fading.

Q: Explain "Low-E" glass.
A: Many skylights these days are made of Low-E (which stands for low emissivity) glass. Low-E glass was first designed for energy efficiency, but now it has the added benefit of blocking heat gain and also heat loss through a skylight. It  can provide a comfortable light and it does not darken the skylight, like tinted glass does. Both tempered glass and laminated glass can include a Low-E feature. Greater benefits are gained through Low-E2, which is a denser version with a slightly darker look.

Q: Can a skylight be removed from the roof later?
A: Yes, it can. If a skylight is correctly installed, it can be removed it is curb-mounted.

Q: Why would you choose tubular skylights?
A: Tubular skylights are a less expensive choice if you are seeking to highlight an area with natural light. These skylights install quickly and are economical because they don’t  require the construction of a shaft from the roof to the ceiling below it. They do lack the drama of traditional skylights, but are an excellent choice for  adding natural light to a small area such as a closet,  hallway, or a small bathroom.

Q: Can skylights function as light fixtures at nighttime?
A: Yes, they can. You can buy a kit that turns your skylight into an artificial light fixture.
