Replacement Windows in Lansdale, PA

Residential Window Replacement in Lansdale, PA

Old windows stick, fog between the panes, rattle in the wind, and leak air around the frame. That shows up as drafts in winter, hot rooms in summer, and water stains at the sill. We inspect each opening, explain what is failing, and recommend replacement when the unit or the frame is done.


Janville measures, supplies, and installs replacement windows on homes across Montgomery County. The opening is flashed and trimmed so water stays outside and the window looks built into the wall. Pair windows with new siding when you can so the exterior is finished in one project.

REPAIR OR REPLACE

Window Repair vs. Replacement in Lansdale, PA

A sticky sash or a worn lock does not always mean a new window. Hardware and weatherstripping can sometimes be repaired if the glass and frame are still sound. Fogged glass, failed seals, rotted sills, and chronic drafts usually mean the unit should come out.

Full replacement makes sense when the siding is brittle, badly faded, pulling away, or letting water in at multiple walls. New siding also lets us straighten lines, update the look of the house, and finish the exterior in one project. We inspect first and tell you which path is worth the money.

How a Janville Window Project Works

We start with measurements and a written estimate. On install day the crew protects the rooms and exterior, removes the old units, and sets the new windows plumb and flashed. Interior and exterior trim are finished so the opening looks complete. We walk the house with you, check operation, and clean the site before we leave.

Fog between the panes, condensation that will not clear, frames that move or rot at the sill, and rooms that never stay comfortable are the usual signs. You may also see water stains under the window or feel air at the lock and meeting rail.



One failed window can be swapped on its own. When half the house has the same issues, a full replacement is cleaner and costs less than doing them one at a time for years. Call (215) 368-5200 if you want the openings inspected.

DON’T IGNORE A DRAFT

FINISH THE EXTERIOR ONCE

Windows and siding installed together

New windows in tired siding still look unfinished and can leave flashing gaps at the opening. Doing both at once lets us wrap, flash, and trim every window against new siding so the wall is tight.

Ask for a combined estimate when we come out. One schedule, one crew, and one cleanup is easier on the house than two separate projects a year apart.
