When it comes to replacement home windows, Home Depot offers some of the most competitive prices on the market. Not only that, but their installation services are also top-notch. I have had some issues with the installation of the windows, as they did not arrive with the fixing flange as requested. However, their contractors are always willing to help you understand any tax rebates or relief you may receive by opting for windows with a certain energy rating. Before making your final decision, it's important to look at all the window and door suppliers available.
You should get additional offers before you buy, especially if you have a larger project and don't plan to do the installation yourself. Fortunately, you can easily find the energy ratings of all the storefronts offered in Home Depot in one prominent place. The quality of the window itself was good, but the installation was not up to par. No foam was shot in the cracks and crevices, so there is a little draft. If you're looking to replace metal windows with vinyl and they will be going to a house with vinyl siding, it's best to use an expert in the field rather than a more generalized company like Home Depot.
If a defect is later discovered in the windows and it has to do with the production process, you will usually need to deal directly with the manufacturer. In my case, I may have a special situation because my current windows (they are narrow profile) have a higher than normal installation cost. It's important to understand the differences between replacement windows and new construction windows before making your purchase.
