Is it Cheaper to Replace Your Own Windows? An Expert's Perspective

Replacing windows can be a daunting task, especially for DIYers. While it may seem like a cheaper option, making mistakes can cost you more in the long run. Contractors often get preferential pricing from window manufacturers, but the high labor rates may still exceed any money you'll save if you order your replacement windows yourself. Homeowners are unlikely to save money by replacing windows themselves, unless they are professional window installers.

The longer homeowners wait to replace windows that are leaking and have water damage, the more serious the problem can become. Some companies only offer replacement windows through one of their licensed installers, limiting homeowners to buying windows directly. Replacing all windows at once will often save you money, as installers usually quote a fixed price for the job and their overheads remain the same for a part or full work day. It's up to you if you prefer to pay less now for cheaper windows and have to replace them in three to five years or if you want to spend more and have your windows replaced for a decade or more.

Along with all of the parts and labor required to replace a window, there are some tangentially related factors that can also affect the size of your final bill. Unique challenges include custom parts made to fit non-standard sizes, repair or replace rotten or broken moldings, match historic architecture, eliminate counterweights, upgrade to current code standards, and fill empty areas with insulation. Two of the most important factors affecting the cost of a window replacement are the window frame material and the type of window. One way to know if the window needs to be replaced is to pick up a lighter and keep it close to the window.

Structural repairs, insulation, waterproofing, job location, and removal and cleaning costs can add to the total cost of window replacement. Before installing replacement windows, homeowners should consider the size, function, and appearance of the window. However, a retrofit window replacement is only a good option if the wooden or aluminum frames you already have are structurally sound. Doing it yourself may seem cheaper at first glance but making mistakes can cost you more in the end.
