Professional vs. DIY: Making the Right Choice for Window Installation
*Updated January 2nd, 2025
1. Installation Done Right
A window that isn’t put in right can let in air and water, making your energy bills go up. These extra costs can add up and might even cost more than if you had hired a professional from the start. Deciding to fix or install windows yourself might seem like a good way to save money at first. It’s true, doing it yourself can save you the money you’d pay someone else to do it. However, it’s important to think about the costs that can come up later. Unless you’ve installed windows professionally, you may not get the installation just right. Even 1/8 of an inch difference in the fit and you could have water and air leaks, neither of which you want, especially with brand new windows. Energy loss can cost you more than you’d save on the window installation. Plus professional installers know the quirks of each brand, ensuring proper fit and installation.
2. Professional Advice
A good window installer should help you choose the right windows if you haven’t done so already. Whether you’re wondering about a certain style or function or you need to stay within a specific budget, who better to go to than the professionals? Professional installers can go over the pros and cons of each window option and will likely cover aspects of window installation that you didn’t even think of but that could save you a lot of money over the life of the windows.
3. Legalities and Building Codes
Imagine installing your windows, feeling a sense of pride and accomplishment, only to be informed later that your hard work violates a local building code. Such a scenario could lead to fines, mandated reinstallations, or, in severe cases, legal repercussions, transforming your feel-good DIY project into a strenuous, costly ordeal. Professional window contractors will be familiar with the permits required for window installation. They can adeptly handle the paperwork, inspections, and any other administrative tasks required, removing this burden from your shoulders. Their experience allows them to foresee and avoid potential legal hurdles, ensuring that the installation process is smooth, compliant, and hassle-free.
4. Access to Better Windows
Shopping for windows at your local hardware store is a lot different than getting them directly from the manufacturers. You’ll have access to higher quality windows when you work with professional installers. They may even provide their advice or opinions on various windows given their personal experience. Nothing compares to personal experience, especially from installers that have seen the good and bad.
5. Better Warranties
A window installed improperly and not in compliance with the manufacturer’s instructions could void the warranty, leaving you unprotected against defects and additional costs. All windows come with warranties, but you’ll likely get a better warranty on windows bought from a professional installer. Not only will they guarantee the windows themselves, but also the labor. Human error happens and the right installer will live up to the mistake and make it right at no cost. If you install them yourself, there’s no one to fix it but you and it will likely cost you more money in further supplies or even a whole new window.
6. More Curb Appeal
Your windows play an important role in your home’s curb appeal, believe it or not. They don’t seem like they’d make much of a difference, but they do and professionals know this. If you’re choosing a style or color that may take away from your home’s curb appeal, the right installer will tell you and point you in the right direction.
7. Time Savings and Reduced Stress
Professional installers are efficient and experienced, able to complete projects in a fraction of the time it might take a DIY enthusiast. They know the potential pitfalls and have the tools on hand, so you’re not left with prolonged periods of construction or needing to fix mistakes. This saves not only time but also reduces the stress of dealing with unforeseen issues, which can add up with a DIY installation.
8. Enhanced Safety Measures
Window installation involves more than just fitting the glass and frame—it often requires climbing ladders, handling heavy panes, and working with sharp tools. Professionals are trained in safety protocols and have the right equipment to avoid accidents or injuries during installation. Their expertise ensures that both you and your home are protected throughout the process.
9. Proper Insulation and Sealing
Beyond simply placing the window in the opening, professionals understand the importance of insulation and sealing to maximize energy efficiency. They use specialized materials and techniques to ensure a snug fit, preventing drafts, water infiltration, and energy loss. This level of precision is difficult to achieve without the right training and experience.
10. Comprehensive Cleanup
After the installation, professionals handle the cleanup, removing debris, old windows, and packaging materials. This ensures your home is left in pristine condition and saves you the hassle of dealing with disposal or recycling requirements.
Selecting the Right Window Contractor
Choosing the right window contractor is necessary for a successful window installation project. The task might appear challenging, but a few simple steps can help ensure you make the right choice. Start by asking for recommendations from friends, family, or neighbors who’ve had similar work done. Word-of-mouth references can provide honest insights and lead you to reliable professionals. When you’ve got a few names, check out their reviews and ratings online to see what other customers have to say about their work. It’s essential to look for contractors with a solid reputation for quality work and good customer service. Once you have a shortlist, reach out to the contractors and ask them about their experience, certifications, and whether they are insured.
It’s also a good idea to ask for references and, if possible, check out some of their completed projects. This can give you a clearer picture of the quality of their work. Discussing your project with them can also help you gauge their knowledge and expertise, allowing you to see if they’re the right fit for your needs. It’s also important to get quotes from several contractors to compare prices, but remember, the cheapest option isn’t always the best. Consider the value they bring in terms of quality, reliability, and service. Finally, a good contractor will be transparent and open about the process, costs, and timeframes, and they should be willing to answer any questions you have. They should provide a detailed, written contract that outlines the scope of work, costs, and timeline. Take your time to read it carefully and make sure you understand everything before signing. Remember, the right contractor will not just provide a service; they will be your partner in ensuring your window installation project is a success, bringing value, and peace of mind to your home improvement endeavor.
