Windows Installed to Fit and Seal

Window installation and replacement services in Denver that improve energy efficiency and home comfort.

If you feel a draft near your windows in Denver during winter or notice condensation between the panes, those are signs the seals have failed or the installation wasn't done right the first time. Blanks Construction LLC handles window replacement and new installation with attention to fit, flashing, and insulation so your windows perform the way they should.

The work involves removing the old window without damaging the surrounding trim or siding, preparing the rough opening so it's square and level, and installing the new unit with shims and fasteners that hold it in place without warping the frame. Flashing is applied around the exterior to direct water away from the opening, and gaps are filled with low-expansion foam to seal out air without bowing the jambs.

Why proper installation affects long-term performance

Window replacement in Denver starts with measuring the rough opening and selecting a unit that fits without forcing or leaving large gaps. The sill is checked for rot or water damage before the new window goes in, and any damaged framing is repaired first. The window is set level and plumb, then secured with screws placed in the mounting flanges or through the side jambs depending on the window type.

After installation, you'll notice the sash opens and closes smoothly without sticking, there's no visible daylight around the edges when the window is shut, and you don't feel air movement near the frame on windy days. Interior temperatures stay more consistent, and condensation on the glass reduces if you've upgraded to double or triple-pane units.

Blanks Construction LLC works with vinyl, wood, and composite window styles common in local homes, and the service is available for both remodels and single-window upgrades across the surrounding communities in Lancaster County. Exterior trim is caulked and painted if needed to match your home's siding.

Here's what homeowners typically ask

Before replacing windows, most people want to know what causes drafts, how long the work takes, and whether the new units will actually make a difference in comfort and energy use.

What causes condensation between window panes?
That means the seal around the insulated glass unit has failed, allowing moisture to enter the space between the panes. Once that happens, the only fix is replacing the glass or the entire window.
How do you make sure the window doesn't leak after installation?
Proper flashing is layered over the top and sides of the window, and a sill pan is installed underneath to catch any water that gets past the exterior seal. Blanks Construction LLC uses peel-and-stick membranes and caulking that flex with temperature changes.
Why do some windows stick or won't stay open?
That usually happens when the frame isn't installed square or the sash balances are broken. A properly installed window operates smoothly and holds position without props or force.
When should you replace windows instead of repairing them?
If the frame is rotted, the glass seal is broken, or you're losing heat around the edges, replacement makes more sense than ongoing repairs. Older single-pane windows also cost more to heat and cool than modern insulated units.
How long does a window replacement take?
Most single-window replacements in Denver take two to four hours depending on the condition of the opening and whether trim needs to be replaced. Multi-window projects are scheduled over several days to maintain security and weatherproofing.
