The Risks of DIY Window Installation

DIY window replacement

Home improvement has been gaining popularity for several years now. If you factor in the cost of material and labour, things can get quite expensive quickly, especially if it’s a bigger project. So, naturally, homeowners might look at DIY or do-it-yourself options to reduce costs. In some areas of the house, you don’t necessarily need any specialized knowledge to get the job done. However, going DIY can become a bit more challenging when it comes to window installation.

Today, we’ll explore the risks of DIY window installation and why it might be better to hire a professional window replacement company for your future vinyl window installation.

The Risks of Replacing Windows Yourself

The temptation to install your new windows yourself is strong. After all, you’ll be spending considerable money on modern, high-quality windows that will save you money in the long run. But if you can save on the installation cost, how difficult can it be, right? Well, given that windows play a critical role in protecting your home against the elements, drafts, burglars, and more, getting the installation right is critical.

One of the most significant parts of a window’s efficiency lies in the proper installation so that any errors can lead to structural issues and other problems. Improper installation can lead to leaks and drafts that can allow water and air into your home. Water seeping into your walls can then also lead to mould and mildew and cause even bigger issues. However, during the installation process, there is also the risk of damaging bricks or framing, which could compromise the structural integrity of the whole wall. 

Product Damage

Installing windows on your own also carries the risk of damaging the windows or frames. The glass can break, or the frames could warp or crack if you drop or overshim them. But even if nothing breaks, trying to install windows with the wrong tools or not knowing how to handle them properly can lead to scratches or cracks that may not seem like a big deal but can harm the looks and potentially also lead to more problems down the line.

Less Efficient

As mentioned before, windows are meant to be energy-efficient and firmly separate the interior from the exterior. Professional window installers have years of experience getting a window to fit perfectly and sealing and insulating it for maximum efficiency. Whether it’s to ensure the right fit, apply the right amount of the right caulk or be able to adjust things where they might need a little shim for the perfect fit, many DIYers simply lack the experience to know the details by heart.


Windows are large, bulky, and often heavy, and handling them is not an easy job. You have to get them off the truck and to the house and then lift and hold them to keep everything in place while you do the installation. Even with help, it can be challenging if you don’t know how to properly lift and handle them to avoid damaging the windows in the process or hurting yourself when trying to manoeuvre them around. 


Many homeowners underestimate the time it takes to install a window. It’s not a “lift in place, snap it in and done,” but there are a lot of steps involved that can get challenging quickly. You might have a timeline in mind, but you underestimate how long it takes; you might encounter a problem, the weather might not cooperate, and many things can influence this. And you must keep in mind that removing an old window leaves your home open to external elements, which can cause problems with your security, comfort and privacy.


“In with the new” is great, but the “out in the old” can become a scrappy and potentially expensive endeavour. You’ll need to take the old windows and any debris from the replacement to the dump and probably pay for scrapping. If you don’t have a truck, you might also have to rent one, adding to the expenses.

Unexpected Costs

DIY projects are notorious for unexpected costs due to miscalculations, oversights, or unforeseen complications. Unless you have a pretty well-equipped toolbox, you might have to invest in several tools and other necessary materials, such as caulking, spray foam, flashing, etc., which can quickly add up. Professional installers have all the tools and materials they need and also the experience to use them efficiently.


As mentioned above, windows are heavy, with the average-sized window between 30 and 40 lbs, so it’s easy to hurt your back when trying to lift one. Depending on the height of your window or if you have two stories, falling off a ladder could also severely hurt you. And obviously, you can never forget that broken glass can be razor-sharp and cause mild to severe cuts. Professional installers don’t only have the experience to handle windows properly but also have liability insurance in case of an accident so that you won’t be liable for any potential injuries

Wrong Window Size

Windows are generally custom-made products that can’t be size adjusted if something goes wrong. They would have to be remade completely if you don’t want to risk them not fitting properly and compromising their performance or structural integrity. Measuring windows properly is not as easy as it seems because you have to take several factors into account. Professional installers do this every day and know exactly which measurements are crucial and from where to where you must measure to get the right measurements.

Limited Warranty

Finally, windows are an investment in your home, as well as safety, comfort, and energy efficiency, so you want to ensure they are protected beyond the installation. If you opt for the DIY approach, you will only get the manufacturer’s warranty on defects, not labour. Sometimes, even those warranties may stipulate that they must be professionally installed. Some home insurance policies also state that a professional installation is necessary for coverage.

If you get a professional window replacement company to do the installation for you, you know that they will properly and professionally install the windows and also guarantee the quality of the installation, so if you encounter any issues after, they will come and fix it at no additional cost.
