Keep the Heat In and the Cold Out
Old, drafty windows and poorly sealed doors are one of the biggest sources of heat loss in Montana homes. DB Builders installs quality replacement windows and doors that improve energy efficiency, comfort, security, and curb appeal — products built to handle Butte's cold winters and temperature swings.
We handle the full installation — removal of existing windows and doors, proper flashing and sealing to prevent air and water infiltration, and a clean finished installation inside and out.

Quality windows with low-e coatings and proper installation dramatically reduce heat loss in Montana winters — a real difference in your monthly heating costs.
New windows and doors come with modern locking hardware and reinforced frames that improve your home's security over aging single-pane windows and hollow-core doors.
Double and triple-pane windows significantly reduce outside noise — a meaningful upgrade if you live near a busy street or in an area with significant ambient noise.
Proper installation means proper flashing and sealing. No drafts, no condensation between panes, no water infiltration around frames.
Windows & Doors FAQ
What type of windows work best in Montana?
Double or triple-pane windows with low-e glass coatings are the best choice for Montana's cold winters. They significantly outperform single-pane windows for heat retention and condensation control.
Do you supply the windows and doors, or do I need to purchase them separately?
We can work either way. We can source and supply products as part of the project, or install products you've already purchased. Let us know your preference when you request an estimate.
How disruptive is window replacement?
Most window replacements are completed in a single day per window, with minimal interior disruption. We work efficiently and clean up after ourselves each day.
Can you replace just one window or door, or do you require a full project?
We replace single windows and doors as well as doing full-home window replacements. No project is too small.
What areas do you serve?
We serve Butte, Anaconda, Deer Lodge, Bozeman, Helena, and the surrounding Southwest Montana area.
