How Much Does Window Installation Cost In New London?

The price of window installation or replacement is influenced by several factors, including the materials you choose, how difficult your windows are to access or install, and the number and size of the windows. On average, New London homeowners spend about $280 per window*. Below are additional cost breakdowns. *Cost data based on sample pricing for window installation from multiple retailers and adjusted for local cost of living.

When To Replace Windows

Installing new energy-efficient windows can substantially boost your home's value, noise reduction, comfort, insulation, and appearance. Some clear indicators it's time to invest in new windows include the following:

  • Condensation issues, fogging between window panes, or rotting window frames allowing moisture intrusion into the home.
  • High energy bills and discomfort from poor insulation.
  • Drafts and cold air coming in through old, loose-fitting windows.
  • Inefficient and outdated window styles that reduce your house's curb appeal.
  • Windows that are hard to open, close, or lock properly due to wear and age.

How To Choose a Window Company

Hiring an experienced window installation professional contributes to good results and a great experience. Below, we outline the main criteria for identifying a qualified window installer.

Experience

Look for well-established local companies with many years, ideally decades, of experience successfully installing all types of windows. These providers are more likely to have a deep knowledge of New London's climate and local homeowner needs. Request references from recent clients to verify quality and experience.

Certifications

Look for installers that are backed by major window manufacturers and accredited by top industry associations, including the Fenestration and Glazing Industry Alliance, formerly known as the AAMA. Appropriate credentials mean that a provider has gotten proper training in quality installation methods. Ensure installers are employees, not subcontractors, and verify that the technicians assigned to your job have the right certifications.

Reputation

Spend time reading through online reviews, checking the Better Business Bureau, and requesting local references. Review customer feedback to verify that the company regularly provides good workmanship and service. Avoid companies with complaints of poor or incomplete work.

Process

A quality provider will give you a detailed project plan, well-outlined timeline, clear expectations, and an overview of all material and installation options. Avoid providers that offer unclear quotes or timelines. Insist on consistent contact throughout the process, so you aren't caught off guard once the work begins.

Warranties

Research contractors that back their work with guarantees and provide warranties on products and labor. This demonstrates confidence in their window installations. Look for unlimited lifetime warranties that can even transfer to new homeowners.

Materials

Ensure that a company installs durable, energy-efficient window brands that work with your budget. Look for good energy ratings, design flexibility, and enhanced UV protection. Confirm the window materials have their own manufacturer warranties as well.

Frequently Asked Questions About Window in New London, CT

In New London, the best time to install windows is when temperatures are mild, generally in the spring or fall. These conditions enable installers to work without having to worry about the weather.

The ideal type of replacement windows for your New London home depends on when your home was built –the average house in New London was built around 1968. For older homes, you may want to consider efficient windows such as double-pane windows, which are designed to keep your home cool in the summer and warm in the winter. Wood frames also have a timeless look that's great for older homes. For newer homes, you can consider vinyl windows, which are affordable, durable and have a modern look.

The most expensive windows are double-hung windows. They are more complicated than single-hung windows, which makes them more costly. Single-hung windows are the least expensive on the market. Vinyl and aluminum are the most affordable frame options.

The process for installing windows typically begins with measuring the existing windows and ordering new ones. Next, a professional installer will prepare the work area, remove the old windows, and install the new ones. Once this is done, the installer will trim the opening and finish by sealing the window.

If you live in a rainier climate like New London, you should wipe off any debris or dirt buildup on the windows often. Additionally, you need to check your windows monthly to make sure they're still functioning properly. It's also a good idea to get a professional to inspect your windows once a year for any potential damages or issues.

Yes, many window companies offer payment plans for their services. Different companies have their own financing options, so you should do your research to find the best option for you. Depending on your income level, which is a median of $56,237 a year in New London, you may be able to qualify for special financing.
