How to Tell if you Need New Windows

Let’s be honest—spending money on windows isn’t a high priority for many homeowners. Because choosing new windows can be overwhelming and costly, you may wonder if you actually need replacements. Here’s how to tell if you need new windows.  

• Wood is rotting on the inside or outside of your window.
• The windows are drafty. Check for drafts by closing the window and holding a candle to it. If the light flickers, there’s probably a draft.
• Caulk that is not sealed correctly.
• The windows have warm or cool zones. On a hot or cold day, check for these zones by holding your hand over every inch of the window frame and feeling for a change in temperature.
• The windows don’t open or close properly.
• Your current windows require too much maintenance.

Home Window Replacement Alternatives

Even if you decide to replace your windows, the method you choose is dependent upon the age of your home and the type of windows you have. You also might decide to only replace sashes. Check out these home window replacement alternatives to see which is right for you:

Replacing the Entire Window

Many people choose to replace the whole window, even if the existing window is in good structural condition. This way, they know today’s materials ensure the new window will be insulated and sealed correctly.

In the case of a whole window replacement, you have a wide range of options. For whole window replacement, it is necessary to remove trim work on the interior and exterior of the window. This generally is not a big problem and is more easily done in new homes. However, it involves more labor and usually more material costs.


Pocked Window Replacement Method

The pocket method is most common on double-hung windows or sliding windows. This method is very popular in much older homes or character homes with older-style trim work, where the homeowner does not want to disturb the interior or exterior trim work.

A pocket replacement window is manufactured to fit inside an existing window frame already installed in your house. For example, let’s say you have wood double-hung, single-pane windows with storm windows in your house. A pocket replacement window is perfect for this application.

Sash Replacements

A sash is the framework that holds window panes in the window frame. If sashes need to be replaced, sash replacement kits are available. These include new sash and jamb liners for older double-hung windows and are typically less costly than other options.

I just spoke with Dave V. by phone, but wanted to be sure that my appreciation did not go unnoticed. Jeff and Mark of your residential division just left my home after spending two days replacing several storm damaged windows.  I am calling and writing to express my deep appreciation for their professionalism, expertise and spirit.  They are both an asset to your company.  With a positive experience like the one I have experienced, you can bet that if there is additional work that I need done, Omni will be my first call.   ~ Thom N.

My recent experience with Omni Glass & Paint was fantastic. I had been waiting 3 months for a part for our front door from another glass company in Oshkosh. I reached out to Omni Glass & Paint; they came to look at the door, found the part and installed the part in less than a day. The door works perfect now. I was so impressed with Omni’s work and would highly recommend them to anyone. – Matt Bakalars, Fox Valley Savings Bank

Mark and Jeff installed windows in our home in Oshkosh.  We were extremely happy with their work but more than that, they went above and beyond to install those windows and were extremely friendly and informative along the way.  They even found an issue with rotten wood that the workers who installed our siding just covered up…so we are very grateful. Because of their services we would highly recommend Omni Glass to everyone.  And the windows are outstanding too!   ~ Roxanne D. – Oshkosh, WI

I just called to compliment the man who installed my new shower door.  Jeff was very pleasant, he did an AWESOME job, everything is perfect, and he left the place neater than when he arrived!  Everything lines up, everything fits, nothing leaks! I am so happy with the job he did!   ~ Nancy, Oshkosh, WI

I just wanted to congratulate the great crew we had working at my home, they were fantastic.  I am very, very pleased with their knowledge and abilities, they were the most impressive group of people I have ever worked with. Mark was especially helpful, he was absolutely wonderful to work with. Thanks again!   ~ Rick, P
