Frequently Asked Questions

You have questions. We have answers.

1. What are various windows made of and what will work best for me?

Basically there are three types of materials used. Aluminum windows, with their easily scratched painted surfaces, conduct both heat and cold, so they’re very poor insulators. Wood windows, which require constant painting and caulking, can absorb moisture, making them difficult to open and close. They can even rot. Our solid vinyl windows, however, never need painting and won’t show scratches, because the color goes throughout the material. This is why vinyl windows are quickly becoming the most popular choice for both new construction and replacement applications.

In addition, you should certainly consider custom-sized windows for the very simple reason that they’ll fit better. Stock-sized windows require extensive carpentry work both inside and outside your house. That can be very costly and inconvenient. SEVEN SUN custom-sized windows, on the other hand, are manufactured to fit your existing window opening. You get the style and options you want while maintaining your glass area.

2. Is there any difference in how windows are made?

There are two basic types of construction: Mechanically fastened windows are screwed together at the corners. There are also welded windows, becoming more and more popular that use a chemical or heat process for joining. Our manufacturer produces mechanically fastened and welded windows. Our mechanically fastened windows feature a unique overlap corner design for extra strength, while our welded versions utilize state-of-the-art heat welding equipment. Beware of windows with mitered corners screwed together or chemically welded corners, as they probably won’t perform as well for you.

3. Can I replace my old windows with different styles or types?

Certainly, because we offer a wide variety of custom window styles and shapes for whatever style of your home may be. You may want to consult our design specialist to find the type of window that best complements your home’s natural design. No matter what style or combination of styles you choose, however, our manufacturer can custom-manufacture it all for you.

4. Aren't all windows manufacturers essentialy the same?

Not at all. Many companies buy their parts and glass from various outside sources. Our manufacturer extrudes most of their own parts from the raw vinyl (PVC) resin themselves.

You should also know that although a lot of manufacturers claim their windows are American-made, many in fact may be imported from Canada and other foreign countries. We’re proud to say that every window SEVEN SUN installs is manufactured right here in the U.S.A.

5. What about strength, protection and noise reduction?

You should look for a window that offers both superior strength and energy efficiency. Our windows are manufactured using a computer-controlled process that ensures a perfectly square window sash and mainframe with superior strength. And for exceptional energy efficiency, a full interlock at the meeting rail helps protect your home against the elements, or unwanted intrusions. In addition, our insulating glass unit traps either Argon or Krypton gas (that depends on your choice), creating an exceptional comfort barrier.

Moreover, homeowners with windows installed by SEVEN SUN say there’s a noticeable reduction in the amount of noise that enters their homes. A full interlock system at the point where upper and lower sashes meet helps stop air infiltration while providing an additional barrier against unwanted intrusions.

6. Do windows from SEVEN SUN require a lot of maintenance?

Because our frames and sashes are made of vinyl, you can say goodbye to painting and caulking. Our windows won’t stick, and you don’t have to go outside or use a ladder to clean them. In fact, you can do it all from inside your home. An occasional wipe with a damp cloth will keep your windows looking like new for years to come.

7. I have been reading about different test results on windows. How should this impact my buying decisions?

Be careful when looking at extremely specific results since many of them do not really indicate how well the window will work for you. Some apply to just certain parts of the window, like the center of the glass and its R-value, and do not give an overall picture. Tested in nationally-certified labs and our manufacturer’s own modern test facility, our windows are engineered to provide the optimum in energy savings and are monitored by the National Fenestration Rating Council.

8. What is more important in saving energy, the frame or the glass?

Since 80% of a window is glass, real heating and cooling savings come from what is known as “improved glass performance,” not a high R-value on the frame. Our windows are made using the latest technology, known as a high performance warm edge spacer system. This spacer system helps to improve the performance and the longevity of the insulated glass unit, and is standard on all SEVEN SUN.

9. What energy-saving options should I know about?

You should give careful consideration to the TG2 Triple Glass Insulated Glass Package. This package features not two but three panes of Low-E (low emissivity) glass with two chamber of argon gas. Low-E glass is an excellent barrier against ultraviolet rays which fade carpet, furniture, draperies, and even woodwork. In regular double -glass window there are 2 layers of Low-E coating. TG2 package features 4 layers of soft-coat Low-E that is applied to the inner part of glass making it impossible to damage or scratch while cleaning. Argon gas is colorless, odorless, nonflammable, nontoxic, and above all, a safe, inert gas that is heavier than air.

Not only does argon gas help to increase the energy efficiency of a window, but helps to make your home quieter as well. When your windows are equipped with the TG2 Triple Insulated Glass Package, they automatically exceed the energy-saving requirements for all four climate zones set forth by the ENERGY STAR® Window program. Or you can get the Triple glass package with Krypton gas that provides even further energy efficiency as an option.

10. What is the ENERGY STAR® Program?

The ENERGY STAR® program was created by the Environmental Protection Agency and the U.S. Department of Energy to help consumers in the recognition of energy-efficient products. This program also promotes the environmental and economic benefits of these products through the ENERGY STAR label and other program activities.

11. Will windows from SEVEN SUN be a good investment?

Yes, for a variety of reasons. First, you may realize savings on your heating and cooling bills. Second, they’re virtually maintenance-free, which eliminates painting costs. Third, the transferability of one of the strongest warranties in the business may easily add to the resale value of your home. And finally, our professional installation and post-installation service will ensure years of trouble-free operation. And this simply saves your valuable time and energy.

12. Aren't all window warranties practically the same?

Not really. There are as many warranties as there are window manufacturers. Some brand name factory warranties cover just the sash and frame. The rest is left up to the local fabricator who may or may not cover it. Your warranty is only as good as the company behind it. With SEVEN SUN, your window is warranted from the extrusion and parts to the glass and construction by our Free Lifetime Warranty , with transferability provisions. It’s one of the most comprehensive available, just what you’d expect from the professional company.

13. How long will I wait for my new windows?

All windows from SEVEN SUN are custom made. Unlike consumer grade stock windows sold through the home improvement retailers, professional-class windows are customized to your exact measurements for a better fit and more secure and energy efficient windows. Please allow 2 to 4 weeks before we install your new windows – tailored just for your home.

14. How longtime does the installation take?

While it may take anywhere from 1 to 5 days, we finish most (about 75%) window installations in just 1 day. Factors that decide about the timeframe of your window project are:

  • number and type your of windows,
  • the age, size, and style of your home,
  • any special requests on your part in regards to the installation process etc.
15. Do I need to move my furniture and take off the blinds/draperies before the installation?

In order to make the installation process more efficient, we ask that our customers move the furniture, if necessary, so that installers have easy access to the windows that need to be replaced. However, if you feel that you may not be able to do it by yourself, please let us know in advance so we can plan the installation accordingly and have our installers do it for you.

16. What about my beautiful hardwood flooring? I worry that installers may damage it during window installation.

Our installers always cover the floor in the working area with drop cloth and use special care not to damage your floor regardless of its type. We take respect your home and take great pains to protect it during installation.

17. Do I need to be home during installation?

It is entirely up to you. If you feel more comfortable to be home during installation, let us know what day would work best for you so that we can fit the installation day into your schedule. However, if you are, for example, a busy professional or you are planning a vacation at the time of installation, let us take care of your window project so that you can take care of your busy life. There’s really no need to change your plans because of the window project.

18. Will you take my old windows with you?

Yes. Upon completion, we will clean up all the debris and will haul away your old windows. You don’t have to worry about going to the landfill or paying for dumpster.

19. What insulation do you use around windows?

Over the years we tried using different types of insulation from batt insulation to the foam insulation that is already attached to the window frame. And we learned that the best solution is professional grade spray-in window and door foam insulation. It fills all the gaps around the window securely without bowing the frame. The problem with batt insulation is that if too much insulation is inserted in the window opening, it loses its insulating value. On the other hand, if installers put in too little batt insulation it is easy to overlook and leave gaps in insulation. That may cause drafts around the window. Sometimes foam wrap, which is basically a thin piece of insulation wrapped around window perimeter, is used. The two problems with foam wrap are that: first, it does not insulate entire width of the window jamb, simply because it’s usually narrower than window jamb, second, often it leaves gaps in all four corners of the window frame. Although it is a little more time consuming, for every window and door project we use spray-in foam. It is a minimal-expanding foam with a low pressure build that forms a durable, airtight and water-resistant seal between a window or door frame and its rough opening without bowing or bending the window frames. In most European countries, this type of insulation has been, for decades, the main choice for building professionals.

20. Will you replace an interior trim?

Normally, if the interior trim is in good shape, we will re-install it after new windows have been installed. However, we can, at your discretion install brand new interior trim for the more complete window project. Just ask us about your interior trim options during an in-home estimate.

21. Will you replace an exterior trim?

In 99% of homes, there’s no need to replace existing trim. We will cap an existing exterior trim with professional grade PVC aluminum. The benefits of capping exterior trim by SEVEN SUN are:

  • professionally installed with extreme attention to details for that beautiful newer look of your home,
  • virtually no maintenance, no more scrapping, sanding, and painting,
  • secures the existing trim from the elements and creates weather proof barrier.
22. Do you install windows during winter or should I wait until spring?

Yes, SEVEN SUN installs windows during winter months so you don’t have to wait till spring. During cold winter months, you may see the highest energy bills of the year due to the old inefficient windows. SEVEN SUN installs only high performance energy efficient windows that will start saving you money on energy bills right away. We will replace your old window with a new window one window at the time. This method will minimize the exposure to the cool air and will allow us to keep you as comfortable as possible.

23. Shoul I keep my storm windows?

It is entirely up to you. However, we recommend that old storm windows be removed and exterior trim be capped with professional grade PVC aluminum. Your home’s exterior will look newer. Plus, our windows are so energy efficient that your old storm windows will provide only marginal benefit in regards to the energy efficiency.

24. Do you install shuters?

Yes. Our shutter collection features the natural look of textured wood with colors that go clear through. They are available in a variety of styles and sizes to complement the scale and architecture of your home. The strong, one piece polymer construction makes these shutters nearly impervious to water and airborne pollutants. The ability to resist the fading, chipping and cracking caused by the hot summer sun’s harmful ultraviolet rays, is more important than ever. In the winter these shutters stand up beautifully to the effects of bitter cold, driving rain, sleet and snow. You can count on years of beautiful service on your home.

25. What is the payment schedule?

50% due at signing. 50% due upon completion.
