How Installing Energy-Efficient Windows in Delhi Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, including:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
• Reduce your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Delhi

Each window replacement company offers various services and has different prices based on a few factors.

How Much Do New Windows Cost?

The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. But costs will differ considerably depending on your location, the current condition of your home, the number of windows you need and the quality of your products. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $633 a year on your energy bills in Delhi.

We recommend getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

There are typically two kinds of window installation services: full-frame and pocket installations.

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Delhi, the choice will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Delhi

In our search to make your home improvements easier and more eco-friendly in Delhi, the EcoWatch team chose the above companies as the best window installation companies in the city. We have evaluated the top window installers in Delhi mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Delhi, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Delhi.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have nice things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
