How To Choose a Window Company in Nashua

Each window provider has different offerings and approaches. To ease the company search, keep these factors in mind:

Window Cost by Type

When you're shopping for new windows, it's essential to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Although top-of-the-line windows may be more expensive to buy, they often yield better long-term value due to their extended lifespan. The final cost of your window replacement will hinge on the specific materials, styles, and sizes you need. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. An expert can help you with picking the products that fit your preferences.

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 $234-$1437
Awning $339-$944
Bay $781-$5794
Custom $347-$965
Casement $270-$1566
Double-hung $126-$815
Egress $231-$578
Glass Block $46-$586
Picture $203-$1502
Single-hung $91-$1545
Skylight $115-$1394
Sliding $266-$1351
Storm $54-$381
Transom $283-$592

Window Material Cost

You'll also need to pick a window material. Homeowners frequently make their selection by considering the local climate, aesthetic preferences and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less up-front, but you'll need to invest in regular maintenance to prevent the frame from warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window Types Average Cost
Aluminum $54-$1545
Composite $557-$1253
Fiberglass $91-$781
Vinyl $187-$1738
Wood $278-$1566

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, permit application fees, and labor. Be sure to discuss each of these elements with a sales representative before committing to a window company.

Experience and Training

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

Licensing and Credentials

In New Hampshire, local governments can establish their own licenses, permits, and guidelines for service providers, including window installation companies. We strongly recommend calling your local building office to see what's required of contractors in your area. You can also visit each company's website to check for private accreditations and professional memberships. The two most well-known certificates come from the AWDI and Fenestration and Glazing Industry Alliance.

Types of Windows Offered

There are several replacement window types you can choose from, and it's vital to find a company that has expertise with the ones you want. Search a company's website and reviews for any of these types:

  • 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 provider if it offers the frame material you want, such as composite, vinyl, aluminum, wood, or fiberglass.

Customer Feedback

One of the simplest ways to vet a company is to check what other customers have written about their experiences. Trustworthy sources for customer reviews include Yelp, the BBB, and Google 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 Nashua

How could new windows help my energy efficiency?

In Nashua specifically, most homeowners using efficient windows cut their carbon emissions by 150 pounds each year. This means they save $460 on their annual electricity costs.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By upgrading to new, more efficient windows, you can boost your home's energy efficiency and minimize your electricity bills.

When's the best time to replace my windows?

With Nashua's cold and snowy winters, it's best to schedule your window replacement for the warmer months. You might also choose to replace your windows in the autumn, when costs may be lower.

My window screen tore. How should I fix it?

It depends on the size of the tear and its location on your window. You can usually repair small tears yourself using a special kit. Some window providers will supply you with one when they set up your windows, or you can get one for $5–10 from a home improvement store. Larger tears, or those located at the edge of a window, usually need professional repair.
