Window & Glass Repair Service FAQs

How long does it take to replace a storefront window in Denver?

In general, a straightforward replacement of a standard-sized storefront window can take around 1-2 hours, while a more complex installation requiring custom glass and framing may take several days.

Factors that will affect the time needed include:

  • Size of the window
  • Type of glass
  • The complexity and accessibility of the installation
  • Availability of materials
  • Weather conditions
  • Permits needed

It is best to consult with a professional window installer to get an accurate estimate of the time required for your specific project.

How much does it cost to replace a sliding glass door near Denver?

On average, homeowners in the Denver area can expect to pay between $1,000 to $3,000 for a standard sliding glass door replacement. Factors such as energy efficiency features, glass type, and additional options like blinds between the glass can also affect the overall cost. If you choose a French door style expect to pay more than the average.

Can you replace glass in a window without removing the frame?

Yes, it is possible to replace the glass in a window without removing the frame in certain cases. This is often referred to as retrofit replacement or insert window installation.

Today, I replaced an old skylight for a homeowner. The existing unit had developed leaks around the edges, compromising the roof’s weatherproofing. I began by removing the damaged skylight and cleaning the surrounding area to ensure proper adhesion. I then installed a new Low-E glass skylight, which improves energy efficiency. After sealing the edges with high-quality silicone and securing the flashing, I tested the seal to ensure it was watertight. The new skylight allows natural light into the home while providing better insulation and eliminating the previous leaks. The installation was completed smoothly and efficiently.
