Windows & Doors FAQ

Here are some sure signs that your old windows need to be replaced:

– Drafty, with air leaking through or around the window
– Excessive condensation or icing on the inside of the window panes
– Windows rattle in the wind
– Paint chipping or peeling
– House is always too cold in winter – or too hot in summer
– Difficult to open or close

This is one of the most commonly asked questions by homeowners. In comparing price, it is critical for you to understand what you are getting for the money you will be investing. Be sure that you are making an “apples-to-apples” comparison. If a price sounds too good to be true, it probably is, and some critical ingredients will be missing. Extensive dry rot or other damage around existing windows may require repairs before new windows can be installed. Depending on the type of repairs needed, this will add to the cost of your new windows. Be sure the estimate includes disposing of the old windows. So, why the diversity in price? While some companies are only in the business to engage in a “one-shot” transaction, the more reputable companies are in business to build relationships and make a small profit. These companies build their business slowly through word of mouth and an impeccable reputation for integrity, honesty and service. This type of window company has clients who know that at any given moment they can call on their company where someone will answer to immediately help solve any problems they may have.

Custom replacement windows give you the perfect fit. Stock windows are available only in standard sizes. When your window opening is larger than a standard size, you’re left with an opening around the perimeter of the window. This opening is often filled with sheet rock or molding and you are left with extra all space to patch and paint. Custom replacement windows allow you to maximize your viewing area without jeopardizing the visual esthetics of your home.

It is strongly recommended that you have a professional install your custom windows. It is critical that the measurements of your windows be exact. Otherwise the new windows will not fit. A professional installer will also have the necessary tools to do the job correctly.

In most cases, we normally install 10 to 15 windows per day.
