Replacing your windows is a significant investment in your home’s value, comfort, and efficiency. If your windows are drafty, outdated, or damaged, choosing the right installer is essential. The quality of the installation affects durability, energy efficiency, and your home’s overall appearance.
With dozens of contractors in the Minneapolis–St. Paul metro alone, how do you decide who to trust?
This guide outlines the key factors to consider when selecting a window replacement company, so you can feel confident in both the process and the finished product.
1. Look for a Company with Local Experience
Window installation is not one-size-fits-all. Climate, housing stock, and building codes vary by region — and Minnesota’s seasons are especially demanding. You need a company that understands local conditions and knows what works for Twin Cities homes.
At RESIDE, our restoration and window installation team has decades of combined experience working specifically with Minnesota and Illinois homeowners. We know how to keep your home warm in the winter and cool in the summer with properly installed, energy-efficient windows.
Pro Tip: Ask how many projects the company has completed in your ZIP code or city. Local references are a good sign of trust.
2. Check Licenses, Insurance & Credentials
Before inviting anyone into your home, confirm they’re properly licensed and insured in your state. This protects you in case of accidents or damage — and filters out fly-by-night operators.
Ask to see:
- Contractor license number (and verify online)
- General liability insurance
- Workers’ compensation coverage
You should also look for certifications from window manufacturers, like Andersen or Pella. These demonstrate that the company trains its staff to install their products correctly.
3. Review Past Work & Project Photos
Seeing is believing. Does the company showcase a portfolio of real, recent projects? Look for:
- Before-and-after photos
- Variety of window types (casement, bay, double-hung, etc.)
- Projects in different home styles — from Tudors to mid-century to new builds
4. Read Reviews — Not Just the Stars
High ratings are important, but reading individual reviews is also key. This helps you understand the customer experience better.
Look for reviews that mention:
- Timeliness and professionalism
- Clean-up process
- Communication and customer service
- How the team handled problems (every contractor hits bumps — it’s how they respond that matters)
Check platforms like Google, Houzz, Facebook, and even neighborhood forums.
5. Understand Your Window Options
A reputable company will guide you through available options without pressure. Quality window replacement involves more than just swapping frames—it’s about making choices that align with performance and design.
Ask:
- What window materials do they offer (vinyl, fiberglass, wood)?
- Are the windows ENERGY STAR® certified?
- Do they offer windows from specific manufacturers or provide custom sizing options?
- Can the new windows be designed to match your home’s existing architecture?
Design matters. Poorly matched or generic windows can diminish your home’s curb appeal and even reduce its value. Many contractors focus solely on functionality, overlooking how window choices integrate with your home’s architectural style. Choose a company—like RESIDE—that takes the time to understand your design goals and helps you select window features that enhance both appearance and performance.
6. Ask About Installation Process & Timeline
Window replacement can take a day or several days depending on the project. Get clarity on:
- How many installers will be on-site
- Whether the job will be subcontracted (or done in-house)
- Cleanup procedures
- Weather considerations
Don’t be afraid to ask for a day-by-day breakdown. A trustworthy company will welcome the questions.
7. Get a Transparent Quote — and Know What’s Included
Cost is a critical consideration, but it should be weighed alongside factors such as quality, service, and long-term value.
Your quote should include:
- Materials and labor
- Disposal of old windows
- Trim or exterior repair (if needed)
- Warranty terms
At RESIDE, we provide clear, detailed estimates that eliminate surprises — because we know long-term satisfaction starts with transparency.
8. Carefully Review Warranty Coverage
Before making a final decision, ensure the company provides comprehensive warranty information in writing. Inquire about:
- Product warranties offered by the window manufacturer
- Workmanship warranties covering the installation itself
- The specific terms, duration, and conditions of each warranty
A reputable company should clearly outline all warranty coverage. If the details are unclear or the representative cannot give clear answers, it may show a lack of trust.
