FAQ

What types of window issues do you fix?

We address a variety of problems, such as rotten wood, cracked or foggy glass, faulty hardware, and damaged sashes or frames. Our expertise includes replacing double-pane windows and insulated glass units, as well as replacing broken glass.

We also offer re-caulking, rotten wood repair, and older window restoration to ensure both functionality and aesthetics are maintained.

Signs like foggy windows, difficulty operating the window, or visible issues like cracks, rotten wood, or deformation may indicate the need for repair.

Rising energy bills could suggest poor insulation due to damaged seals or frames. Moisture buildup, condensation, or mold around windows also signals potential problems.

Prompt repairs can prevent further damage and maintain efficiency.
We begin with a thorough inspection to assess the issue, whether it’s rotting wood, broken glass, or hardware malfunction.

After diagnosing the problem, we provide a detailed quote and schedule a convenient time for the repair. Our skilled technicians will then address the specific damage, repairing or replacing the necessary parts, such as the sash, frame, or glass units.

Finally, we ensure the windows function smoothly and improve energy efficiency, giving your windows a renewed look and performance.
Yes, we do. If you have a serious window issue that needs immediate attention, contact us right away, and we’ll help you as soon as possible.
Yes, we offer warranties on all of our repairs. Our coverage includes 3 years on hardware repairs, 10 years on woodwork, and a 20-year warranty on the thermal seal of insulated glass. This ensures that our high-quality repair services give you long-lasting peace of mind and protection.
You can get a quote by filling out the form on our website, calling us, or emailing us with your window issues. We’ll arrange a visit at a time that works best for you to conduct an initial inspection of your windows and provide you with a detailed quote.
Clear the area around the window so our team can work easily. This helps us finish the repair quickly and effectively.
We always prioritize repairs whenever possible, but if your window can’t be fixed, we can suggest replacement options (like sash replacement or a new window installation) that suit your needs and budget.
You can reach us by filling out the contact form on our website, calling us, or sending an email. We’re here to help with any questions and to schedule your repair.
