How To Choose a Window Company in Gaithersburg

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

Window Cost by Type

When you're shopping for replacement windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Although top-of-the-line windows may come with a higher initial price tag, they often provide better long-term value due to their increased lifespan. The age of your home, together with the sizes, styles, and materials of windows you select, can affect pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. It's wise to speak with a trusted window installer to decide on your best options.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Arched$232-$1427
Awning$336-$937
Bay$775-$5751
Custom$345-$958
Casement$268-$1555
Double-hung$125-$809
Egress$230-$574
Glass Block$46-$581
Picture$201-$1491
Single-hung$91-$1533
Skylight$115-$1384
Sliding$264-$1342
Storm$54-$379
Transom$281-$587

Window Material Cost

Replacement window prices also vary based on material. Each option gives you unique advantages depending on your climate and energy efficiency needs. Vinyl and fiberglass are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost
Aluminum$54-$1533
Composite$553-$1244
Fiberglass$91-$775
Vinyl$186-$1725
Wood$276-$1555

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to factor in the cost of labor, warranties, and any other supplemental fees that your project may entail.

Experience and Training

Browse a company's website and talk to a representative to learn more about its product and service offerings, pricing, and guarantees. Many window companies also keep online portfolios that present past projects.

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been active, the more likely it will provide high-quality craftsmanship.

Licensing and Credentials

Window installers and subcontractors in Maryland must carry a license from the state's Home Improvement Commission. Each applicant for a license must successfully complete a trade and business exam, submit business filings, verify surety bond information, and show financial responsibility.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's important to find a company that is experienced with the ones you want. Browse a company's website and reviews for any of these types:

Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as aluminum, vinyl, fiberglass, composite, or wood.

Customer Feedback

One of the most surefire ways to evaluate a company is to check what other customers have said about their experiences. Read customer reviews on sites such as Yelp, Trustpilot, and Google. 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 Gaithersburg

Why should I hire a professional to install or replace my windows?

Window replacement is a significant expense that greatly impacts your home's comfort and energy efficiency. Hiring a skilled window installer to manage your project ensures your windows will be properly installed, perform efficiently, and be properly insulated. Companies also typically include a guarantee that addresses required maintenance and most needed fixes.

Does window replacement involve pulling permits?

Window replacement may require obtaining permits, depending on your local building codes and regulations. Some municipalities mandate permits for window replacement projects when they involve structural changes or alterations to the window openings. We recommend checking with your local building department or consult a professional before undertaking any window replacement work.

Do window installers also work with blinds and coverings?

Whether a company installs blinds ultimately depends on your state's licensing requirements and their own preferences. Many jurisdictions require window covering installers to get a separate license, and not every professional will carry one. If you'd like blinds with your new windows, inquire with a company representative if its crews can handle the measuring, cutting, and mounting. If a company can't work with blinds, they could recommend another company or subcontract the work.
