Can I install just 2 or 3 windows at a time?

Of course! We sell plenty of partial-order projects.

If you can only do a few windows at a time, we’ll work within YOUR budget. We also offer excellent financing to help secure you a monthly payment that’s comfortable for you.

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

Absolutely. You want the type of window that best complements your home’s natural design. No matter what style or combination of styles you choose, however, we can custom-manufacture it for you.

What is the process of getting new windows installed?

Getting windows at Rescom breaks down into three simple steps:

  1. Schedule an appointment with a Rescom Window Consultant to determine the perfect solution for your home.
  2. After you’ve signed the agreement, we’ll have an expert come and measure each opening to ensure a flawless fit.
  3. We will contact you to set up your installation date. After installation, you can relax and enjoy your new windows!

Can I have new windows installed in any weather?

Yes. In fact, most homeowners will experience the best results from new replacement windows when they are installed in the winter or summer.

Do your windows require 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 remove storm windows in order 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.

Will new windows from Rescom help with condensation?

They definitely can. Condensation is a direct result of interior humidity and the difference between indoor and outside air temperature. The efficiency of your window will also impact the temperature and humidity level at which condensation occurs. Our energy-efficient windows will help reduce condensation.

Here’s why: high-performance windows with low U-factors result in inside glass surface temperatures much closer to the room air temperature. Windows with warm edge technologies and non-metal frames are also less likely to have condensation on the frame or at the edge of the glass.

Three layers of insulated glass will greatly reduce condensation on the interior surface of the glass–even under extreme cold weather conditions. Note that in certain conditions (humid mornings after a clear night sky), some triple pane windows may have dew on their outside surface. These windows are such good insulators, the dew is condensing there just like it does on an insulated wall.

Will your windows reduce outdoor noise pollution?

Yes. Our windows can reduce outside noise by up to 66%. Visit our Whisper Quiet page for more details.

Aren’t all window warranties practically the same?

Not at all! 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.

When you choose Rescom windows, your unit is warranted from the extrusion and parts to the glass and construction for a full 50 years, with transferability provisions. It’s one of the most comprehensive warranties available—just what you’d expect from an industry leader.


What is a replacement window?

A replacement window is a window that’s custom-built to fit within the opening of an existing window. It is a custom-measured item designed to fit exactly and can be normally installed without removing or disturbing the interior and exterior stops/trim work around the window.

What’s the difference between the windows in my home now and replacement windows?

When your home was built, the window openings were made to accommodate a stock size window, whereas replacement windows are typically manufactured to custom fit existing openings.

The biggest differences are reduced maintenance, ease of operation, and thermal performance features driven by new technologies.

How is replacing my windows different from putting windows in when the house was built new?

Your house now has finished siding, walls, and trim, which you probably want left intact after the windows are replaced to minimize disruption and cost.

A replacement window is made to fit into your old window’s sash opening (the area of glass including its frame and any hardware) and doesn’t require the removal of interior or exterior casings.

The installation of a new construction window (most likely what is being replaced) would require removal of the entire window including its jamb, head, sill, and casings to expose the stud opening.

Although certainly an option, this method is more labor-intensive and invasive and would involve walls and siding beyond the casings.

Why is a custom measured replacement window system preferable to an “off the shelf” window?

Standard or lumberyard windows are always cheaper—unless you take into consideration the increased costs of labor and the problems with how to trim or finish out the inside of the window opening.

Custom windows will provide the best energy performance, the best fit, and the most attractive look for your home.

What are the best reasons to install new windows in my home?

Save Money on Energy Bills: If you have single-pane windows, upgrading to our triple-pane Windows will result in unbelievable year-round energy savings.

Improve Your Home’s Appearance: Our high-quality vinyl and selection of styles and hardware options can improve the look of your home both inside and out. Often, simply changing the window style can dramatically change the entire appearance of a room.

Increase Ventilation: Get more fresh air circulating in your house by replacing fixed units with operable venting windows. You’ll be amazed at the difference quality windows make to the quality of life in your home.

Will replacement windows really improve the value of my home?

Yes, for a variety of reasons. First, you will realize savings on your heating and cooling bills. Second, quality replacement windows are virtually maintenance-free, which eliminates painting costs. Finally, the transferability of a window’s warranty may easily add to the resale value of your home.

The top things future homebuyers look for in a new home are kitchens, bathrooms, and windows. Curb appeal is very important to your home and investing in new energy efficient windows will definitely be a great advantage if you ever want to put your home up on the market.

How should I clean my new windows?

When cleaning windows and doors, use the mildest cleaners possible. NEVER use solvents or abrasive cleansers -some chemicals can harm vinyl and PVC surfaces and other window components.

We recommend Fantastik® and similar products to clean vinyl window frame surfaces. Over-the-counter glass cleaning products are recommended for cleaning windows.

What is the difference between the cheap vinyl windows I see advertised on TV versus better quality vinyl windows?

There is a huge difference in the quality and performance of different windows. The glazing technology, glass system, vinyl composite, profile, and construction of the rails, are just a few things you need to consider.

When should I consider replacing my home windows?

You should consider replacing your windows if…

  • The windows aren’t energy efficient.
  • The wood frames are rotting.
  • They allow excessive amounts of condensation, fading of furniture and draperies.
  • You are tired of painting and staining.
  • You can feel drafts while sitting near your current windows.


How do I know if a window is energy efficient?

The easiest way to compare the energy performance of different windows and doors is to read the National Fenestration Rating Council (NFRC) label.

It provides valuable energy efficiency information about the product. Also, check to see if the product is Energy Star® qualified ENERGY STAR Windows.

For in-depth details, visit our Window Energy Efficiency page.

What is double glazing and triple glazing?

Two or three panes of glass separated by a space (usually filled with an inert insulating gas) to form insulating glass. These are also called double-pane and triple-pane windows.

What is more important for efficiency: 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.

Rescom uses the latest technology to improve the performance and the longevity of the insulated glass unit, and is standard on all windows we install.

What is Low-E glass and why should I care?

Low-e glass is short for low-emissivity glass. It has a very thin coat of material on the glass to make it more efficient, especially in very sunny, hot areas such as the west coast.

It helps reflect standing heat away from the surface of the glass, keeping unwanted heat out in the summer and desired heat inside in the winter.

Low-e glass is the most cost-effective way to increase the energy efficiency of the windows.

Low-e coatings can also help reduce furniture and carpet fading by reducing the amount of ultraviolet (UV) radiation that enters the home.

Harmful ultraviolet radiation can alter the chemical structure of dyes and other colorants in carpets and furniture causing fading.

Everything about this company is great! Right from the beginning with the salesman Ben to the whole crew that came out to do the install. They communicated everything very clearly about the install and what to expect. They actually exceeded our expectations (which is hard to do considering we have had many issues with contractors.) We love the new windows and even saw a decrease on our heating bill. Can't say enough about these guys!!! Definitely consider them when looking for new windows!

What an amazing company. The salesman Ben is so polite and helpful. He’s responsive to emails and always got me the answers I needed. The installation crew was AMAZING. The work done was far better than I expected. The quality of the windows and doors are better than any other “popular” company I’ve used in the past. Highly recommend.

This is the second time I've used Rescom. Very happy with the windows. Easy to open and clean. The patented locking system is nice. Ben has been very helpful. Sales and install teams are professional. Left the areas clean and organized when they were done.
