Hopper Replacement Windows for Basements and Below-Grade Openings
Hinged at the bottom, opens inward. The right answer for basements, foundation-line openings, and secondary ventilation where standard styles don't fit.

Signs Your Hopper Has Aged Out
The patterns that tell you it's time. None subtle once you're looking for them.
Spot one or two? Time to call. We'll come measure and tell you straight whether it's a fix or a full replacement — no pressure.
- Symptom
Water seeping at the bottom track
Bottom-hinged windows below grade are exposed to water at the most vulnerable point — the hinge line. Water seepage means the seal has failed.
- Symptom
Sash won't latch closed at the top
Hopper latches at the top of the sash. When the latch won't engage, the seal can't pull tight.
- Symptom
Visible frame rot in basement openings
Below-grade openings are humid year-round. Original wood-frame hoppers in unfinished basements often have rot at the sill and lower jambs.
- Symptom
Foam insulation cracked at the foundation line
Basement hoppers sit at the foundation transition where settling cracks open up over decades. The original foam packed around the unit no longer seals — air and moisture infiltrate.
How We Install Hopper Windows
Basement hoppers sit at the foundation transition — waterproofing matters as much as the window itself. We verify drainage, flash the rough opening, and seal the foundation interface before the unit goes in.

MEASURE
Below-Grade + Drainage Verification
Hopper installation in a below-grade opening is as much about waterproofing as the window. We verify the well drainage clears, the sill flashing is intact, and the rough opening is sealed against capillary moisture before the unit goes in.
- Below-grade well drainage verified
- Sill flashing inspected
- Capillary moisture sealed
- Custom-fit every opening
MATERIAL
Vinyl for Humidity Resistance
Basements stay humid year-round. Vinyl is the right material for finished basement hoppers — no rot risk and the cost-to-value is strong on a window that's mostly utility.
- Vinyl — basement standard
- Aluminum — utility-grade option
- Humidity-resistant frames
- ENERGY STAR® on premium lines
INSTALL
Waterproofing + Egress Code
Below-grade installs need waterproofing detail that flat-wall installs don't. We flash the rough opening, seal the foundation interface, and verify egress code if the basement is finished as habitable space.
- Flashed against water entry
- Foundation interface sealed
- Egress code verified
- Installation workmanship guaranteed

Where are hopper windows installed in NC homes?
Hopper windows are bottom-hinged and tilt inward at the top, which makes them the standard pick for basements and below-grade openings where the wall is short and the sash needs to clear without projecting outside the foundation line. Common in finished basements, split-foyers, and secondary egress points in eastern NC.
