Window Replacement

Windows are one of the few elements of your home that can be enjoyed both inside and outside of your house. Your choice of a replacement window can have a profound impact on interior décor as well as curbside appeal. In addition, the improved energy efficiency of properly installed replacement windows can pay dividends for years to come. Not all replacement windows are created equal. It is always important to choose the type of window that will best serve your needs as a homeowner. Windows made of wood or vinyl may need to be replaced in as few as 5-10 years based on exposure and quality of product. Windows are exposed to wind, rain, ultraviolet light, and the changing temperatures of the seasons, which cause materials like vinyl and wood to expand and contract, ultimately compromising the window’s fit. For this reason many homeowners are considering fiberglass window products as an alternative to traditional materials because they are stronger and do not expand and contract the way wood and vinyl replacement windows do.

ALL ABOUT WINDOWS

REPLACEMENT WINDOW MATERIALS:
WHATS IN A NAME?

Many homeowners come in to buy windows with a brand name in mind. There is nothing wrong with brand loyalty or using branding as a guide for your purchasing experience. What is really important, however, is knowing what you are buying. Some customers ask for a brand and then they are surprised to find out that they only use one type of window material. Our customers are surprised to learn that the brand they want does fit their goals and needs in purchasing replacement windows.

For this reason, we recommend that buyers think first about the window material that will work best for them. Learn more about the three major types of windows: wood, vinyl, and fiberglass below:

Wood windows are classic. In many ways purchasing a wood window is like investing in a fine piece of furniture. Over time it will need to be maintained and cared for, but the look will be unmistakably classic, especially if you choose to stain. A wood window may be required if you live in a home governed by a historical society. So, if you need a historical, authentic look, take a look at the wood windows we have to offer. You should note that wood’s undeniable beauty comes with a cost and wood windows are usually on the higher end of the cost scale. Also, wood windows expand and contract with the changing of the temperatures. This means that over time the fit of your window may become compromised, resulting in draftiness or seal failure. Below are some details when considering wood:

  • Historically accurate aesthetics
  • Unlimited colors and stains
  • Variety of wood species
  • High efficiency and privacy glass options
  • Convenient cleaning options
  • 20 year glass /10 year non glass component warranty
  • Needs to be maintained
  • Can be considered an aesthetic investment like furniture
  • Usually the most expensive window material option
  • Internal blinds

Fiberglass windows are without a doubt the very best windows you can get. They are stronger than wood or vinyl windows and for this reason they can use a thinner frame, which will give you more glass. Whenever you replace the windows in your home you will be losing a small fraction of the glass in the window due to materials and installation. Fiberglass windows reduce the impact of glass loss when replacing windows. You will get more glass, more view, and more light with a fiberglass window. Fiberglass windows also expand and contract much less than wood or vinyl, making the window fit stay true. Surprisingly with all of these advantages, fiberglass windows are not the most expensive windows on the market. They are available in a wide range of colors and configurations and are appropriate for just about every home style. Once you replace your windows with fiberglass, you will never need to replace your windows again. Below are some details when considering fiberglass:

  • Historically accurate aesthetics
  • Most durable colors and finishes
  • Prefinished, paintable and stainable interiors
  • High efficiency and privacy glass options
  • Low maintenance
  • Convenient cleaning options
  • Most stable, reliable and strongest material
  • Limited lifetime warranty
  • Stronger than vinyl and wood
  • More glass/thinner frames as a result of strength
  • Least amount of expansion and contraction compared to other window materials
  • Approximately 25% more expensive than vinyl, but less expensive than wood

Vinyl is probably the most popular replacement window out there. It is inexpensive, easy to maintain, and there are plenty of options. Vinyl windows, however, expand and contract in the changing temperatures, so depending on how harsh the conditions are, the window can warp in as little as 170 degrees. Vinyl windows also have weld scars (bumping in the corners of the windows where they are attached) that some homeowners find unappealing. For those on a tight budget, vinyl windows are a good option, and we at Lawrenceville Home Improvement carry two brands of vinyl windows that have been proven over time to be of good value. Below are some details when considering vinyl:

  • Low maintenance
  • Prefinished interiors
  • High efficiency and privacy glass options
  • Convenient cleaning options
  • Most economical window material
  • Limited lifetime warranty

Types of Replacement Windows

The three main types of replacement windows available are wood, vinyl, and fiberglass. There are advantages to each type of window frame, and a wide variety of available options. It is important to review all of the considerations, which we will help with.  Windows are one of the few elements of your home that can be enjoyed both inside and outside of your house. Your choice of a replacement window can have a huge impact on interior décor as well as curbside appeal. In addition, the improved energy efficiency of properly installed replacement windows can pay dividends for years to come. Not all replacement windows are created equal. It is always important to choose the type of window that will best serve your needs as a homeowner. Believe it or not, windows made of wood or vinyl may need to be replaced in as early as 5-10 years—this varies based on exposure and quality of product. Remember that your windows are exposed to the elements day after day including damaging wind, harsh bouts of rain, strong sunlight, and the extreme nature of current weather patterns. The changing temperatures of the seasons also contribute to compromising a window’s fit as wood and vinyl will expand and contract with the rising and dropping temperatures. For this reason many homeowners are considering fiberglass window products as an alternative to traditional materials because they are stronger and do not expand and contract the way wood and vinyl replacement windows do

A Word on Window Grids

Grid patterns are very popular in distinguishing the aesthetic of your window. Window grids are a purely aesthetic option that does not affect the functionality of the window. Historically, when large pieces of glass were expensive and difficult to get, window makers would take smaller squares or rectangles of glass and hold them together with grids of wood, creating a design out of necessity. Modern manufacturing has made large sheets of glass far more accessible, and now the look of a gridded window has become an endearing design element that many homeowners gravitate toward.

There are two main ways to have grids installed on your windows: grids between the glass (GBG) and simulated divided lite (SDL). GBGs have the contoured grids nestled between the two panes of glass in the window thereby making the glass flat and easy to clean. GBGs are by far the most popular way to incorporate grids into your window’s design because they provide the look of grids with the ease of a flat piece of glass. This is also the less expensive option when it comes to grids.

SDLs offer a more authentic gridded look. The grids actually protrude past the glass creating the look of old fashioned grids while preserving the insulating properties of double paned glass. Because of the bumps in the glass, homeowners tend to find this configuration a bit more difficult to clean as dust and particles can get wedged in the corners. There are some historical societies that require the SDL grids for replacement windows, so always check to see if your home falls under those guidelines. 

Window Fit is Everything

It can’t be stressed enough that the key to a successful replacement window installation is the fit. This is why Lawrenceville Home Improvement will measure and order your windows according to your specific window opening dimensions. 

Measuring is the first step, choosing the right material is the second step. As referenced earlier, windows are available in three different types of materials: wood, vinyl, and fiberglass (there are also composite materials available, which are usually a combination of vinyl and wood). Wood, vinyl, and composite expand and contract over the years and can compromise the fit of the window. Comparatively, the expansion and contraction of fiberglass windows is so minuscule that the fit of the window will not be compromised over time. This is definitely something to consider when making your replacement window purchase.

When is it Time to Replace My Windows?

Where to Start on Your Replacement Windows

The decision to replace your windows can be a difficult one. Not only is it a significant investment, but many homeowners can become overwhelmed by the many choices available to them. Some ways that you can begin the process include:

  • Read reviews online. Customers are always more motivated to leave negative reviews than positive reviews, so some negativity is always expected. This is all the more reason to give attention to a company that has more positive feedback than negative feedback.

  • Ask the community. Social media offers many ways to ask your neighbors for recommendations.

  • Do some research. We all know that information on the Internet has to be taken with a grain of salt. However, as long as an article compares the three major window materials (wood, vinyl, and fiberglass) then you will be able to get a picture of all of the pluses and minuses available.

  • Visit a showroom. There is nothing like actually touching and feeling a product. Showrooms are the “please touch museums” of home improvement. Get a look at the windows you are interested in to see how they work and compare them to other options.

Also, it is important to determine what your goals and limitations are when choosing a replacement window product. For example:

  • What is the most important factor for you when selecting a replacement window? Price? Value? Sustainability? Aesthetic? A combination of these?

  • Are you planning to stay in your home longer than five years? If so, it may be worth the investment to consider a fiberglass window product.

  • What is your time frame for getting the project done?

  • What is the style of your home? Colonial? Contemporary? Modern? Tudor?

  • Would you like to incorporate a grid pattern in your window?

  • Are you located in a historic district? Will you need to obtain approval from an historical society before beginning your project?

  • Do you have an association that has standards or requirements for window installation?

When to Replace Your Windows

When is the best time to replace your windows? The simple answer is now. Most homes that have been constructed in the past 20 years were built using builder’s grade materials. In other words, the windows were not built to last. The sooner you put new replacement windows into your home, the sooner you can realize the benefits. You will enjoy improved energy efficiency, which will lower the monthly bills. You will also have more attractive curb appeal and enhanced interior aesthetics. And if you decide to sell your home, you can leverage the improved windows as a contributing asset to the home’s value. 

Taking the first step in the window replacement process can be difficult and overwhelming. Many homeowners are not sure that their windows need to be replaced. So one question that we get time and time again is, “How do I know when my windows need to be replaced? Are there any tell-tale signs?” The following are a few questions that we recommend you ask yourself when determining whether or not your windows need to be replaced: 

Are your windows over 20 years old? If your windows were installed 20 years ago, they are probably made of wood or vinyl. Both of these materials expand and contract with the changing temperatures of the seasons. As a result, the fit of the window can become compromised thereby making the window susceptible to leaking. 

Do you have trouble opening or closing your windows? Although mechanism failure can sometimes be repaired, it is more likely a sign of total unit compromise. If your windows are sticking, it often means that the window has expanded and contracted over time and has potentially warped its shape, making it difficult to maintain the track system that opens and closes your window. You can always have a handyman tinker with the window to make it operational, but this route may be costly and repetitive. 

Do you feel a draft? In other words, on a windy day are you able to feel a draft pass through the window cavity? If you feel air coming through, heat or air conditioning is seeping out. A drafty window is a clear call to action to replace your windows. Some homeowners like to use the “tissue test” to determine the severity of their drafting. To complete this test, wait for a windy day and take a tissue and hold it by the frame of your window. If the window is still maintaining a good fit, the tissue will not move. If the window is compromised, you will see clear movement of the tissue. If the tissue moves, it’s time to get your windows replaced. 

Is there cloudiness or fogginess between the glass of the window? Seal failure is the cause of discoloration or fog within the window panes of glass; you will not be able to wipe it off with your hand or a cloth. In some cases you can just replace the glass, but if your window frame has been warped or compromised in any way, the problem will reoccur. In addition to the unsightly discoloration and fogging that results from seal failure, you are also losing the insulation provided by the heavy gas (like argon) used to insulate the window between the two panes of glass. Seal failure is definitely a red flag that the window needs to be replaced. 

Are your windows single paned? Most windows made today have two panes of glass with a heavy insulating clear gas in the middle. If your window is old enough to be single paned, it most likely needs to be replaced. Single paned glass windows are usually only used in homes that need to preserve historical authenticity. But even so, most historical societies will allow double paned glass because of the significant insulation that double paned windows provide. 

What to Expect When Replacing Your Windows With Lawrenceville Home Improvement

In terms of planning your replacement window project, you will need to factor in time for window manufacturing, scheduling, and then the actual installation of the product. Contrary to popular belief, there really is no such thing as a standard-size window. Yes, builders will often use the same size window when constructing developments or planned communities, but this hardly follows a set of standards. As a result, Lawrenceville Home Improvement will only install windows that are custom ordered to insure a perfect fit.

The process starts with a showroom or in home visit. Once you determine the kind of window you would like, final measurements are made of the openings and a price is given. Once a deposit is made on the project and a contract is signed, materials are ordered. Windows can take anywhere from 4 to 9 weeks to be manufactured and delivered. Once the windows arrive, we call to schedule you for installation. Based on your availability, this can take up to two weeks, but we always try to schedule you as soon as the windows come in and weather permits. 

One challenge that every installer faces is the weather. Rain and snow are difficult to overcome and can push back a schedule significantly. Wind can also prevent an installation, especially if second floor work is required using ladders. It is the policy of Lawrenceville Home Improvement to hold off on cancelations until the day of the scheduled installation so that we can have the most current and accurate forecast for the day’s weather. We are committed to protecting your home as well as the safety of our installers.
