How To Choose a Window Company in Lowell

With Lowell's large population, you're sure to find a trustworthy window company that aligns with your values and preferences. As you reach out to companies, keep the following factors in mind:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with quality is vital. Although top-of-the-line windows may cost more upfront, they often yield better long-term value due to their longer lifespan. The style, size, and material of your new windows play the largest role in determining your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. It's advisable to speak with a trusted installer to determine your ideal options.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window Types Average Cost
Arched $253-$1555
Awning $366-$1021
Bay $844-$6267
Custom $376-$1044
Casement $292-$1694
Double-hung $136-$882
Egress $250-$625
Glass Block $50-$634
Picture $220-$1624
Single-hung $99-$1671
Skylight $125-$1508
Sliding $287-$1462
Storm $59-$413
Transom $306-$640

Window Material Cost

Window prices also vary based on material. Each option offers different benefits depending on the local climate and energy-saving goals. Vinyl and fiberglass are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window Types Average Cost
Aluminum $59-$1671
Composite $603-$1355
Fiberglass $99-$844
Vinyl $203-$1880
Wood $301-$1694

Other Window Replacement Costs

Your total cost for window replacement will also include applicable warranty fees, permit application fees, and labor. Make sure to discuss each of these aspects with an estimator before committing to a window company.

Experience and Training

The longer a window installer has been operating, the better its workmanship will likely be. Speak with a company representative to learn more about its public and private credentials, guarantees, and experience. Company websites often have photo galleries showing off previous work technicians have done.

Licensing and Credentials

Massachusetts window companies are classified as general contractors and require a Construction Supervisor License (CSL) with a window classification. CSL applicants need to pass an open-book exam and prove 36 months of work experience. Once a company has a CSL, it also needs to register with the Office of Consumer Affairs and Business Regulation as a "home improvement contractor."

Types of Windows Offered

No two contractors offer the same window styles and materials. Find one that specializes in the type you want for your home.

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as wood, vinyl, fiberglass, aluminum, or composite.

Customer Feedback

Reading other customers' stories is one of the best ways to screen potential window companies. Read customer reviews on sites such as Google, Trustpilot, and Yelp. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

Frequently Asked Questions About Window Replacement in Lowell

How much energy and money will I save by upgrading my windows?

Lowell homeowners could potentially save $460 per year by upgrading to efficient windows. They'll also reduce their property's carbon dioxide emissions by 140 pounds per year.

According to the national Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. Efficient windows help keep heat out in the summertime and retain heat in the wintertime, improving your comfort and furthering your dollar.

Does window replacement involve pulling permits?

Whether you need a building permit to replace your windows varies on your local building codes and regulations. Some towns require permits for window replacement projects, especially those that involve structural changes or alterations to the window openings. We recommend you check with your local building department or contact a professional before beginning any window replacement work.

Do window companies have guarantees or warranties for their work?

Window companies often give assurances for their services. Each typically addresses defects with workmanship and materials for a specified period of time. It's essential to confirm the conditions of the guarantee with a window company before you sign a contract.
