How Much Does Window Installation Cost In Allentown?

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, how difficult your windows are to access or install, and the materials you choose. On average, Allentown homeowners spend around $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

Replacing your current windows with new energy-efficient ones can greatly boost your home's comfort, appearance, noise reduction, insulation, and value. Signs it's time to invest in new windows include:

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  • Inefficient and outdated window styles that detract from your home’s curb appeal.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

How To Choose a Window Company

Hiring an experienced window installer contributes to a great experience and excellent results. Below, we outline the main considerations for identifying a qualified window installer.

Experience

Find well-established local installers with considerable experience. Companies that have been installing windows locally for many years are more likely to understand the local climate and how to best meet your needs. Request references from recent customers to confirm a company’s reputation.

Certifications

Choose companies that have certifications from top window brands, and that have Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Certification means they've been properly trained in installation best practices. Make sure installers are staff rather than subcontractors, and confirm that any technicians working on your home are certified.

Reputation

Spend time going through online reviews, checking the Better Business Bureau, and asking for references from people in your area. Review customer feedback to confirm that a company consistently does quality work and provides good service. Avoid companies with complaints of shoddy work or unfinished jobs.

Process

The right 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 ongoing communication throughout the process to avoid surprises later on.

Warranties

Seek out window installers that back their installations with guarantees and offer warranties on materials and labor. This demonstrates confidence in their work. Choose companies with unlimited lifetime warranties that can be transferred to new homeowners.

Materials

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

Frequently Asked Questions About Window in Allentown, PA

The ideal time to install windows in Allentown is when temperatures are moderate, generally in the spring or fall. These conditions allow installers to do their work with less worry about extreme temperatures.

The best type of replacement window for your Allentown home will vary based on your home's age, as well as your style preference and budget. You'll want to consider the style of your home — such as if it's older — so your new windows match. Wooden windows can provide a classic look and appearance, while vinyl-framed windows tend to be popular in newer homes. Fiberglass windows are also a popular choice, as they can be energy efficient and durable.

The types of window that generally last longest are ones crafted from vinyl or wood, with double glaze for extra insulation. Vinyl windows are renowned for their long-lasting nature and need little maintenance, while wood windows offer a more traditional look. Tripling up on the glazing will reduce energy costs over time.

The window installation process typically involves measuring and ordering the windows, prepping the area for installation, taking out the existing window, putting in the new one, and insulating the frame. Depending on the kind of window being installed, additional steps might be needed.

Yes, most window companies offer financing options. Some installers provide low-interest or no-interest loans based on your income, while other companies offer special financing plans with agreements and conditions that vary depending on the project.

Getting a professional window installer helps make sure the job is done correctly. Professional installers will measure to get a perfect fit and will use the right techniques and materials to ensure your windows are properly sealed and fitted. Additionally, professional installers are likely to have access to better materials and more knowledge than the average homeowner, so you can count on your windows to be installed correctly and last for years to come.
