How Much Does Window Installation Cost In Wilmington?

The amount you'll spend on window installation or replacement will be influenced by a number of factors, including the number and size of the windows, the materials you choose, and how difficult your windows are to access or install. On average, Wilmington homeowners should expect to spend about $270 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

Replacing your old windows with new energy-efficient ones can significantly improve your home's appearance, noise reduction, comfort, value, and insulation. Clear indicators it's time to invest in new windows include:

  • Cold air and drafts leaking in from old, loose-fitting windows.
  • Condensation issues, fogging between window panes, or rotting window frames allowing moisture intrusion into the home.
  • Outdated and inefficient window styles that reduce your home’s curb appeal.
  • Discomfort and high energy bills from poor insulation around windows.
  • Windows that are difficult to open, close, and lock properly due to wear and age.

How To Choose a Window Company

Hiring an experienced window installation professional helps ensure a great experience and excellent results. Below, we outline the main factors to consider when identifying a qualified window installer.

Experience

Find well-established local installers with lots of experience. Installers that have served Wilmington homeowners for years are more likely to know the local climate and how to best meet your needs. Request references from recent customers to confirm a company’s reputation.

Certifications

Choose an installer that’s certified like major window manufacturers, and that has Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Proper certification shows they've received proper training in installation best practices. Verify that installers are staff, not subcontracted laborers, and confirm that any technicians working on your home have certification.

Reputation

Read through online customer feedback, check the Better Business Bureau (BBB), and request local references. Review customer feedback to confirm that the provider consistently delivers quality work and good customer service. Avoid companies that have complaints of shoddy work or unfinished jobs.

Process

The best company will take time to provide you with a detailed project plan, timeline, expectations, and reviews of all material and installation options. Beware of vague quotes or timelines that don't provide enough specifics upfront. Look for consistent communication throughout the process to avoid surprises later on.

Warranties

Research providers that guarantee their installations and provide warranties on labor and materials. This is a sign of confidence in their window installations. Seek out unlimited lifetime warranties that can be transferred to new homeowners.

Materials

Verify that your window installer works with long-lasting, durable brands, offers power-saving window options, and fits your budget. Look for window options with good energy ratings, design flexibility, and enhanced UV protection. Check whether the materials include their own manufacturer warranties.

In Wilmington, the best time to install windows is when temperatures are mild, generally in the spring or fall. These conditions allow installers to work with less worry about the weather.

The ideal type of replacement windows for your Wilmington home depends on the year your home was built –the average house in Wilmington was built around 1958. For older homes, you might want to consider energy-efficient windows such as double-glazed windows, which are made to keep your home cool in the summer and warm in the winter.

This includes removing the old windows, measuring for the new windows, installing the new windows, and caulking them in place. In general, it takes around 30 minutes to install each window.

You should wipe off any debris or dirt buildup from the windows when they get dirty. Additionally, you need to check your windows monthly to make sure they're still functioning properly. It's also a good idea to have a professional inspect your windows once a year for any potential damages or issues.

Yes, many window installers offer financing for their services. Different companies have their own financing options, so you should shop around to find the best option for you. Depending on your income level, which is a median of $54,731 a year in Wilmington, you may be able to qualify for lower interest rates.
