Frequently Asked Questions

How do I find good window repair contractors near me?

If you find yourself needing home window repairs, it can become an emergency situation pretty quickly if you are unable to board up your window or take other precautions as to not let the elements in. You are most likely in a pinch to get your home window repaired quickly – if so, you won’t have time to compare local window repair contractors to make sure you are getting the best price. This is where Modernize can help: we can get you in contact with up to four top local window repair contractors quickly, so you can get your windows fixed fast.  


Before being contacted by local, reliable contractors who can help, it will be beneficial to know an estimate of the size of glass pane and home window style you are looking to repair or replace. Your home window installer will be able to give you a roundabout estimate before coming to your home, but it could vary depending on a few factors about the window in question. 


How do I know if I need to repair my windows?

If you are trying to figure out if you need to repair your windows or completely replace them, there are a few things to look for that can help you decide. 



  • Detecting Drafts: 

    • Check for drafty breezes coming from closed windows, which may indicate bad seals or wear on the original installation. 

    • Escaping air impacts HVAC costs and significantly affects your home’s energy efficiency. 



  • Difficulty in Operation: 

    • If windows are hard to lock, slide, or open/close, it could be a sign of shifting in the house or damage to the framing. 

    • Difficulty in usability may necessitate repair or replacement. 



  • Condensation Issues: 

    • Condensation between window panes suggests ineffective window seals. 

    • Persistent condensation is an indicator that the seals may need attention. 



  • Rotting or Soft Frames: 

    • Soft and rotting window frames indicate water damage or wear from external elements. 

    • Such frames might require complete replacement instead of a simple repair. 




By assessing these aspects, you can make informed decisions about whether your windows need repairs or if it’s time for a complete replacement. 


What are some local contractor warning signs to avoid?

Before choosing your contractor for an affordable window repair or replacement, be sure that you can fully trust them and that their estimate is transparent and complete. 


Door-to-door contractors, for example, flock to areas impacted by storms and can scam unsuspecting homeowners with offers that boast prepayment or covered deductibles. The best way to avoid scams is to choose a local, trusted contractor — someone who has been around your area for a length of time.  


You will want to work with someone whose reputation and reliability are central to their success. You can confirm this by checking their physical business address and validating their licensing. 


Here are some warning signs that can protect your local window repair or replacement project: 



  • Avoid contractors who request the entire window replacement cost, or large cash deposit, up front. A down payment should not exceed 10% or $1,000.  

  • Avoid anyone who pressures you to sign a contract immediately after meeting. 

  • Be wary of any outliers in your quotes. All window replacement estimates should be relatively similar in costs unless the material type is significantly different. 

  • You’ll want to avoid any window contractors who are not licensed or insured. 


When it comes to window replacement projects, there are some hidden costs homeowners could be surprised by down the line. The best way to avoid these is to ask the contractor about them beforehand to ensure that they won’t be an issue or that they are already accounted for. 


Is it advisable to work with a licensed or certified window replacement professional?

Absolutely. Opting for a licensed and insured contractor provides a safety net in case any issues arise during the window installation. Collaborating with such professionals ensures the efficient handling of both major and minor project details. 


At Modernize, we uphold stringent standards through regular quality checks on our contractors. This process involves: 



  • Reviewing business profiles and customer feedback received. 

  • Conducting background checks on contractor companies. 

  • Verifying local licenses, certificates, and adherence to necessary policies by contractors. 


Our commitment extends to connecting you swiftly and effortlessly with reputable local window repair and replacement contractors. This enables you to receive genuine quotes, compare prices, and select the most suitable professional for your window replacement project. 


How comparing multiple quotes lowers project cost?

While considering multiple contractors may feel time-consuming, it could save you hundreds (or thousands) of dollars off your home improvement project.
