Coal Town Roots

Miners’ cottages, modern neighborhoods.

The Welch Mine opened in 1877, and Louis Nawatny platted the town beside it the next year. Mining lasted until 1955, and the houses it left behind, small wood-frame homes on the blocks around Main Street and Front Street, are still the heart of Old Town. Many have been added onto over the decades, so window openings are rarely standard sizes. We measure every opening on site.

If your Old Town home is a designated local landmark or you’re applying for historic preservation help, check with the City of Louisville’s historic preservation staff before you change windows. We’ll give you the product details and drawings a review typically asks for.

Beyond Old Town, Louisville spans 1970s neighborhoods like Parkwood with ranches, bi-levels and tri-levels; Centennial Heights and Hunters Ridge; the golf-course homes of Coal Creek Ranch; Harper Lake near Davidson Mesa Open Space; and newer construction in Steel Ranch and the North End. After the December 2021 Marshall Fire, many Louisville homes were rebuilt from the ground up, while others nearby are older homes with original windows still in place.

Wind & Hail in Boulder County

Louisville weather tests every window.

Louisville sits where strong downslope winds come off the foothills and where spring and summer hail crosses Boulder County. After a storm, we document window and exterior damage, write a detailed estimate and coordinate with your insurance adjuster when a claim is part of the project.

We’ll tell you plainly what needs replacing and what doesn’t.

Insurance claim assistance

We can assist with:

  • Storm damage documentation
  • Detailed repair estimates
  • Property inspections
  • Coordination with insurance adjusters
  • Communication throughout the restoration

Common signs of hail & window damage

After severe weather, watch for:

  • Cracked or broken windows
  • Broken window seals
  • Moisture between panes
  • Drafts around windows
  • Water leaks
  • Visible impact marks
  • Chipped or peeling paint
  • Loose exterior trim

If you notice any of these, schedule an inspection before a freeze or the next storm makes it worse.

Common Questions

Louisville window replacement FAQ.

Answers to the questions we hear most from Louisville homeowners and businesses.

Can you replace windows in an Old Town Louisville house?

Yes. Older wood-frame homes often have out-of-square openings and past remodels, so we measure every opening on site and explain whether an insert or full-frame replacement makes more sense. If your home is a designated landmark, check with the city’s historic preservation staff before changing windows.

Our 1970s split-level has aluminum sliders. What should we replace them with?

It depends on the room. Many homeowners keep sliders in some rooms and switch to casement or double-hung windows in others. We’ll walk each room with you and recommend what fits.

Is Louisville in your service area?

Yes. Louisville is a short drive up US-36 from our headquarters on W 73rd Ave in Westminster, and we also serve Lafayette, Boulder, Broomfield and Erie.

Do you help after hail or wind damage in Louisville?

Yes. We document damage, provide detailed estimates and can coordinate with your insurance adjuster as part of storm restoration.
