Best Window Companies

Windows come in several different shapes, styles and sizes. Depending on the style of your home and your budget, you may have a specific style of window in mind. Typical window options on the market today include:

• Double-hung windows: With two sashes that slide up and down independently, double-hung windows are the most popular type of residential window sold today.
• Casement windows: Popular on contemporary-style homes, casement windows crank open and are particularly well-suited for hard-to-reach installations, such as in front of a kitchen sink.
• Bay windows: These windows project from the house at an angle to provide wide-angle views and architectural interest.
• Bow windows: Projecting out from the house in a gentle arch, bow windows provide a panoramic view of the outdoors.
• Picture windows: Picture windows are stationary windows that add great views and aesthetic value — but they don’t open. They’re often flanked by narrow casements or double-hung units.
• Hopper windows: Tilt-in hopper windows are typically installed in basements and crawl spaces. The narrow sash locks at the top and tips in toward the interior when unlatched.

Types of window frame materials

With windows, material is just as important as style. Window frames are made from vinyl, wood, aluminum, fiberglass, clad or composite materials. Factors such as price, aesthetics, climate adaptation, longevity and energy efficiency vary depending on the window frame material you choose.

Ask the company you’re buying from what material is best for the climate you live in and what’s in your price range. Window materials have come a long way in terms of durability and energy efficiency, and there are several options to choose from.

The cost of window replacement can vary greatly depending on your specific needs. A single window can cost anywhere from around $100 to close to $2,000, depending on the material and size. Multiply that cost by the number of new windows your house needs and the price will quickly add up.

Here’s an overview of what you can expect to pay for each type of window.

There’s a lot of misleading cost advice out there, according to Andrii Gurskyi of Mr. Glazier, a window replacement company in New York. “Most sources don’t include installation costs,” he said. “This leads to surprise costs for customers.”

You can expect to see a difference in the cost of standard sizes versus custom sizes.

“The starting price for a custom window is no less than $400, plus installation costs of a minimum of $350 per window,” Gurskyi said.

Whether you go with standard or custom sizes, installation costs are likely to be the same — and they very much depend on the cost of labor in your area. Gurskyi emphasized the huge range in window costs: “Based on average prices in the New York City market provided by contractors, the cost of replacing a single window ranges from $700 to $3,000.”

Note: These are just estimates; homeowners should get multiple quotes for a more accurate cost analysis.

Keep in mind that New York City is costlier in general than rural areas due to higher labor, transportation, storage and parking costs. Costs also tend to be higher in places that see severe weather conditions because of the need for sturdier materials and specialized installation techniques, Gurskyi said.

Other factors that affect the cost of replacement include the window material, style and size. Wooden windows tend to be the most expensive, while vinyl is the most affordable. Edie, the homeowner in Michigan, paid $2,000 (not including installation) for six vinyl windows that were all the same size: 34 inches by 62 inches. She opted for vinyl because she “wanted well-insulated, double-paned, double-hung” windows.

Factors that affect the cost of windows

Several elements influence the overall cost of replacing windows. Homeowners should consider the following factors:

• Material: Different materials like vinyl, wood, fiberglass and aluminum have varying price points.
• Size: Larger or custom-sized windows cost more than standard-sized ones.
• Type and style: Specialty designs such as bay or bow windows are more expensive than double-hung or casement windows.
• Glass options: Double-pane, triple-pane and energy-efficient glass can increase the cost.
• Installation complexity: Hard-to-reach areas or complicated installations add labor costs.
• Location: Labor and material costs vary by region, with urban areas typically charging more.
• Upgrades: Additional features like impact resistance, UV protection or soundproofing will increase prices.

To find the best window companies in your area, ask around — referrals from local friends and neighbors are best because you want an installer familiar with local building codes.

Here are a few quick tips for finding a good window company and installer:

• Ask for referrals from friends and neighbors.
• Read customer reviews on sites like ConsumerAffairs.
• Look into the company’s window options.
• Decide on a budget and compare company costs.
• Look into the company’s financing options.
• Gather multiple quotes from different window companies and compare.

Once you’ve narrowed your list, it’s time to ask each installer a few more specific questions:

• Is the installer licensed and insured?
• Has the installer been trained or certified to install particular brands?
• How many years of experience with windows does the installer have?

Going through those steps and asking those questions during your search for the best window company will ensure you choose an established company.

Choosing the right windows for your home is a balance of functionality, aesthetics and long-term value. Start by assessing your home’s architectural style — modern, traditional or a mix — and choose window designs that complement it. Energy efficiency is also crucial. Look for windows with an energy-efficient certification to help reduce heating and cooling costs.

Consider how much ventilation you need in each room. Operable windows like casement or double-hung styles work well in living spaces, while picture windows are better for areas where ventilation isn’t as important. Evaluate the durability and maintenance requirements of different frame materials based on your climate and lifestyle. For example, vinyl and fiberglass offer low maintenance, while wood provides a classic look but requires regular upkeep.

Finally, think about natural lighting and views. Larger windows or designs like bay and bow windows can make spaces feel more open and bright. Don’t forget to factor in noise reduction if you live in a busy area — double- or triple-pane glass can make a big difference. Taking time to carefully evaluate these factors will ensure you make a choice that enhances both the beauty and functionality of your home.

Energy-efficient windows are designed to reduce heat loss in the winter and heat gain in the summer, helping homeowners lower energy bills and improve indoor comfort. They use advanced glass, coatings and frame materials to better control how heat and air move through the window.

What to look for

To help you get a better idea of which energy-efficient windows will work for your home, compare these key performance factors.

• Air leakage measures how much air passes through the window assembly. Lower air leakage ratings mean fewer drafts and better overall energy performance.
• Visible transmittance indicates how much natural light passes through the glass. Higher visible transmittance means brighter rooms, but can sometimes increase glare.
• Condensation resistance shows how well a window resists moisture buildup on the interior glass. Higher ratings reduce the likelihood of condensation, mold and water damage.
• U-factor or U-value rates how well a window prevents heat from escaping. Lower U-factor values indicate better insulation and are especially important in colder climates.
• Solar heat gain coefficient measures how much solar heat passes through the window. Lower values help keep homes cooler in hot climates, while higher values can be beneficial in colder regions.

The consensus among installers and manufacturers is that replacement windows last 20 to 30 years. How long yours last depends on a number of factors, including the material they’re made of, weather conditions, how often you use the windows and how well you maintain them.

Vinyl windows require the least care and stand up to the harshest cold-weather conditions, but wood windows can last just as long with proper care.

Signs that it’s time for replacement windows include the following:

• Loss of structural integrity
• Loss of functionality
• Notable airflow when closed
• Shabby appearance
• Condensation
• Noise

Window warranties will vary from manufacturer to manufacturer, but they typically cover signs of wear and tear or deterioration within a specific time frame.

For example, the manufacturer may guarantee that the windows they sell will last 15 years. If something malfunctions or breaks before that time is up, the warranty will cover it.

Some warranties cover parts, hardware and labor; others won’t. Some cover glass and others don’t. The lifetime coverage for some windows may be longer than others, depending on the quality or material of the windows.

Questions to ask

Beware that the wording of warranties can get confusing — here are some questions to ask the manufacturer before you purchase your windows:

• What is the length of the warranty?
• What is covered in the warranty? Is installation covered?
• How quickly will someone be able to come to fix the problem?
• Is there a service fee for someone to come out to fix the window?
• Can the warranty be transferred if I sell my house?

Proper maintenance can significantly extend the life of your windows, saving you money on premature replacements. Here are some practical tips to keep your windows in excellent condition:

By incorporating these maintenance steps into your routine, you can help your windows maintain their functionality and appearance for years to come.

• Regular cleaning: Clean window panes and frames with a non-abrasive cleaner to prevent dirt buildup. Avoid harsh chemicals that can damage the glass or frame material.
• Inspect seals and caulking: Check for cracks or gaps in the seals around your windows. Reapply caulking as needed to maintain insulation and prevent water intrusion.
• Lubricate moving parts: Use a silicone-based lubricant on tracks, hinges, and locks to keep them functioning smoothly and to prevent rust.
• Check for damage: Periodically inspect windows for cracks, chips, or warping, especially after severe weather. Addressing small issues early can prevent bigger problems down the line.
• Repaint or stain wooden frames: For wood-framed windows, apply a fresh coat of paint or stain every few years to protect against moisture and UV damage.
