Window Buying Made Easy
Why Choose Thompson Creek?
Eight reasons why we’re the right choice for your home
Superior Selection
Unlike many window contractors, we are the manufacturers which gives us plenty of options to build the best vinyl replacement windows for your home and budget. Insulated glass packages include double pane, triple pane, or Sound Shield – our revolutionary sound reducing glass package. Other options include locking mechanisms, grid patterns, and a variety of exterior colors when choosing replacement windows.
Expert Installation
A replacement window is only as good as the installation.
Your Thompson Creek windows will be professionally installed using our propriety installation methods designed to outlast our warranty.
Thompson Creek replacement windows are protected by our No-Hassle Warranty on both the product and installation for up to 50-years.
Our installers will clean up the job, and leave your home as clean, or cleaner, than it was when we arrived.
No-Hassle Warranty
Home improvement projects typically have a warranty on the product, as well as the installation. In the typical home improvement supply chain, the manufacturer sells the product to a distributor, who sells the product to a contractor, with costs and mark-ups added along the way. To further complicate the process, the contractor usually hires a sub-contractor to do the installation. In this scenario, there are potentially four parties who could be responsible for your warranty.
What’s more, according to a Harvard Joint Center for Housing Studies, 51% of the general residential remodeling businesses in 2007 were no longer in business in 2012 leaving a trail of who’s to blame for incorrect window installation.
Thompson Creek is the manufacturer and installer, and we are one party responsible for both the product and the installation warranty saving you headaches, and potential additional expenses down the road.
Built For The Mid-Atlantic Climate
There are 4 climate zones in the United States, and choosing the correct replacement window for your climate zone is critical.
For example, if you lived in Miami, you would want a window that defends against solar heat gain, and the sun’s rays making some of the rooms in your home hot and uncomfortable. If you lived in North Dakota, you would want to allow some of the sun’s heat into your home to warm your rooms. Some window manufacturers could try to make a window that covers multiple climate zones to reduce the number of window types they need to manufacture, but this is not in your best interest.
Thompson Creek windows are built specifically for the Mid-Atlantic climate giving you the best solution for our unique climate.
Locally Built
Some of the national firms manufacture windows in the Midwest and have to ship their windows to local dealers. The shipping costs get rolled into the price of your windows.
Thompson Creek windows are locally manufactured in our Maryland facility, and you won’t pay for shipping costs in your Thompson Creek windows.
Beautiful By Design
We use the highest quality vinyl and raw materials to manufacture our windows to add beauty, comfort and value to your home. Every window is built to the exact specifications of the opening where it will be installed. We use premium materials and installation methods to ensure that our windows will outlast our No-Hassle warranty for up to 50 years. Some of our vinyl windows include beveled frames on the exterior of your home to enhance the beauty of the windows. You have several choices in style, glass options, color, screen options, and grid styles and patterns.
AAMA Water And Wind Tested
Thompson Creek windows are laboratory tested to exceed the weather conditions of the Mid-Atlantic region. The Mid-Atlantic region experiences an occasional tropical storm, and we want to make sure that our windows will withstand these conditions. Rest assured knowing that your Thompson Creek windows can withstand up to 146 mph winds and 8” of rainfall per hour to protect you from the potential mid-Atlantic weather conditions.
Remarkably Energy Efficient
Our replacement windows exceed the 2022 Energy Star criteria and are designed to increase your comfort and lower your utility bills, while increasing curb appeal.
Most middlemen are looking for the lowest priced window, to increase their profit margin. We are more interested in using the best raw materials to build a stronger, safer window that will easily outlast our warranty. Both our windows and the installation are covered by our No-Hassle warranty for up to 50 years.
