Questions Before Installation

Is vinyl, fiberglass, or wood the best option for my new windows?

At RUSCO we offer all three options because any of these options may be right for your project. Our professional consultant will be happy to meet with you, listen to your concerns, review your options, and make a recommendation based on your needs, budget, and taste.

What causes condensation?

Excessive humidity is generally the cause of window condensation. As the outside temperature drops, the window glass also develops a lower temperature. When moist air particles in the warmer room come in contact with the colder glass pane, the moisture particles condense and form water droplets. Determining when condensation will occur and preventing it depends on the type of window, the relative humidity level inside your home and the temperature of the air inside and outside.
If you experience condensation on your windows, contact us and our professional consultant will be happy to come out to your home, review your specific situation and, offer you solutions.

What is insulated glass?

Insulated Glass is the combination of two or more panes of glass sealed with air, or inert gas between the panes. The construction of an insulated unit is designed to help control energy transfer from outside to inside or vice versa.

What does Low-E mean?

“Low-E” literally means low emissivity, which in turn means a surface that emits low levels of radiant heat. All surfaces reflect, absorb, and transmit heat. So, a Low-E coating reduces the amount of that heat transfer. When talking about replacement windows the term Low-E really applies to the glass being used.

What is Argon gas?

Argon is the gas most often used between panes in a double- or triple-glazed window. The gas is colorless, non-toxic, and odorless. Argon is denser than the atmosphere, providing more thermal efficiency than having air between the panes.

What is U-value?

The rate of heat loss is indicated in terms of the U-factor (U-value) of a window assembly. The lower the U-factor, the greater a window’s resistance to heat flow and the better its insulating properties.

What is R-Value?

The R-Value is a measure of the resistance to heat loss. Many people are familiar with R value because of its use in home insulation, but actually, for windows and doors, U factor and solar heat gain coefficient are more important measures.

What is Solar Heat Gain?

Solar heat gain coefficient (SHGC) 
is the fraction of solar radiation admitted through a window, door, or skylight — either transmitted directly and/or absorbed, and subsequently released as heat inside a home. The lower the SHGC, the less solar heat it transmits and the greater it’s shading ability.

What is Energy Star?

ENERGY STAR is a U.S. Environmental Protection Agency (EPA) voluntary program that helps businesses and individuals save money and protect our climate through superior energy efficiency products.

Do I need custom sized windows or doors?

Many of the brands we carry offer both standard and custom sized products. Our professional consultant will be happy to educate you on the advantages of either option. Therefore, you will be able to make an informed decision when selecting the products that work best for your project.

How long will I have to wait for my new window, door, siding, skylight, sunroom, or roof?

On average, you new product will arrive 6 to 10 weeks after they have been ordered. This range depends on the time of year and the product purchased. A better estimate will be given by our professional consultant at the time your product is ordered.

Is there a manufacturer’s warranty?

Yes. Each of the products installed by RUSCO has a warranty provided by the product manufacturer. Our professional consultant will review with you each brand we offer and their warranties.

What is the difference between the foam insulation and the other stuff?

RUSCO uses low expansion foam which is specifically designed for window and door installation. This foam expands to fill voids that are sometimes missed by fiberglass batt insulation.

What type of insulation does RUSCO use?

RUSCO uses both fiberglass and low expansion foam that is environmentally conscious and ensures the best insulation possible.

Do you offer full frame replacement with new casing?

RUSCO provides full frame installation with all new interior casing. Alternatively, we provide insert installation when existing interior casing stays. Our professional sales consultants will explain both options and offer an explanation about the best option for your home.

Will my current window treatments work with my new windows?

It depends on a multitude of factors; therefore, please bring this concern to the attention of our professional consultant when discussing your project.

Will I need to paint my interior walls?

Since trim is usually different on newer windows, we can install a thicker trim thereby avoiding the need to repaint your walls.

What happens to the shutters on the outside of my house?

If possible, RUSCO will be happy to remove and re-install your current shutters. However, please discuss this option with your sales consultant when discussing your project. Our professional consultant will also be able to provide you with a written estimate for new shutters.

Questions About Installation

Do I need to provide a dumpster?

No. You will not need the added cost of a dumpster because RUSCO always removes any old product (and related debris) from your property. We also we use a shop vacuum and sweep (if necessary).

Do I need to obtain a permit?

No. Each community has different permit requirement. RUSCO will check with your township and if needed, we will obtain the permit for your project.

How long will it take to install my new product?

On an average size house, all the windows can be replaced in 1 to 3 days. Most doors can be installed in as little as 4 to 8 hours. Siding (with soffits, facing, and gutters) can be installed in 3 to 5 days on a typical home. Roofing is usually complete in 1 day.

Will my (window/door, siding, skylight, sunroom, roof) be delivered directly to my home?

RUSCO has a warehouse and will store almost all products until the day of installation. However, to minimize harm to your product, some products that are unusually sized or heavier than normal may be delivered to your home prior to installation.

Will my house be a mess during and after installation?

Our factory certified installers will use your driveway (or seek permission to use your garage in inclement weather) for all saw work thereby reducing saw dust. They will also sweep the driveway upon completion of the project. We take every measure to reduce the amount of dust inside your home.

Will RUSCO protect my floors and belongings?

Yes. RUSCO has factory certified installers that use drop cloths and runners to protect your floors. You may want to also cover furniture with drop cloths (or bed sheets work great too) for dust protection.


Questions After Installation

Who do I call if there is a service issue?

RUSCO has a full installation and service team of professionals available to you. Just contact us to talk to a professional consultant immediately.

Will I have to paint the exterior of my windows periodically?

No. RUSCO installs low maintenance exterior products and exterior trim that is custom wrapped in aluminum and will not need to be painted.

Will I need to re-caulk the exterior soon?

RUSCO uses an oil-based silicone caulk that is the best in the industry and will not need re-caulking for years.

When will I have to re-stain or do a new clear coat on my new door?

If your door has severe sun exposure it may require top-coat maintenance on the stained door exterior every few years.

How should I clean my door and/or windows when they get dirty?

Mild soap and water usually works well. However, always consult the manufacturers owner’s manual prior to the first cleaning of your new product.
