Yes, we do. We’re happy to come to your residence or place of business to assess your needs and discuss your best options.

Unfortunately we do not at this time. However, we can offer flexibility on payment schedules.

Ideally Spring and Autumn are the best time to replace windows. But, because we install windows only after they have been delivered to us, the exposure to the elements is greatly mitigated.

Not necessarily. Although many clients opt to replace the street-facing windows first, it depends on the condition of the windows.Rear windows might have issues due to shade and would be the logical choice to improve thermal value.

A brick to brick install can be very invasive to the existing building structure, which could include replacing the brick molding, new water proofing, new blocking, and is much more labor intensive therefore more expensive.

An insert install involves setting the new window inside the existing frame, thus is faster and less labor intensive.

Interior condensation is a result of a combination of factors, including stale air, no exchange of air, high indoor humidity, lack of ventilation, and poor insulation. The issue is not just the window. Air and moisture travel to the path of least resistance. The weakest point in your thermal barrier is usually where moisture/condensation will be visible such as the windows or glass. The window and glass is NOT the source of problem. Changing or repairing windows or glass will NOT solve the issue of interior condensation. 
  • Solutions:- Bring in fresh air. Open windows.- Move the air around so air can change. Turn on a fan.- You can change your window to products with higher insulation values. This will help but it will not address the source of the problem.

Condensation occurs between the panes of glass  when the seal fails. The only option is to replace the window.

Our service guarantee information can be found here.

The warranty offered varies by manufacturer. Generally,  glass is 20 years, non-glass components are 10 years, and the finish is 10 years.
