Hopper and Basement Replacement Windows in the Lehigh Valley
Hopper and basement replacement windows in the Lehigh Valley are the openings homeowners quote last and regret ignoring first. The rusted steel hoppers in an Allentown row or the rotted wood units in a Bethlehem twin let in cold air, water, and pests, and a basement window quote is often the difference between a dry, usable lower level and one you avoid.
This page covers what a hopper is, how basement windows differ from the rest of the house, the spec to ask for, and the mistakes that show up as water on the floor.

How a hopper and basement window works
A hopper is hinged along the bottom edge and tilts inward from the top, usually with a simple latch or a crank. Because it opens into the room, it works in a window well or where an outward swing would hit a wall. Basement openings in the Valley also take fixed units, small sliders for egress, and glass-block panels. The frames often sit in masonry rather than a wood rough opening, which changes how the installer attaches and seals the unit.
Where hopper and basement windows make the most sense
- Below-grade openings inside window wells
- Unfinished basements that need light and occasional ventilation
- Replacing rusted steel or rotted wood units in pre-war rowhomes
- Laundry rooms and utility spaces
- Combining with a slider where a basement bedroom needs egress
What hopper and basement windows do well
- Opens inward, so it fits inside a window well
- Compression seal when latched, better than the old steel units by a mile
- Small, straightforward install that fixes a big draft source
- Modern frames resist rot and rust that killed the originals
What to weigh
- Limited ventilation and no egress on its own
- Opening inward can catch curtains or shelves
- Masonry openings may need a buck or new frame, adding to the scope
- Below-grade units need drainage in the well to stay dry
What to ask for on a hopper and basement window quote
A hopper and basement unit is built to order for each opening, so the written quote is where the spec gets locked in. Ask for each of these in writing, per opening.
- 01
Glass package
Low-E double-pane is still worth it below grade for condensation control. Ask for tempered glass at floor-level openings and obscure glass if the well faces a neighbor.
- 02
Hardware
Latch type on hoppers, whether the sash removes for cleaning, and locks on any slider. Basement hardware sees damp air, so ask about corrosion-resistant finishes.
- 03
Frame and buck
How the unit attaches to block, stone, or poured concrete; whether a new treated or vinyl buck is installed; and how the perimeter is sealed against water.
- 04
Color and grids
Usually white with no grids, but confirm. If the exterior is visible from the street on a walkout, match the house.
- 05
Screens
Interior or exterior screens depending on the style. For a well, ask whether a well cover is recommended.
- 06
Warranty
Manufacturer coverage on the unit and the installer’s labor warranty covering the seal to masonry, which is where basement windows leak.
Common mistakes when replacing hopper and basement windows
Leaving the basement off the whole-house quote
Basement windows are easy to forget and the largest source of draft and water in the house. Have them measured with everything else so the order is one delivery.
Ignoring the window well
A clogged or undrained well fills in a storm and floods the new window. Ask the installer to look at the well and note any drainage or cover recommendation.
Reusing a rotted buck
The wood frame set into the masonry is often what failed. A new unit screwed to soft wood will move. Ask whether the buck is replaced.
Assuming the hopper covers egress
A finished basement bedroom typically needs a code-compliant egress opening, which the local code official confirms. Quote a slider or casement of the right size for that room and a hopper for the rest.
Hopper and Basement windows in Lehigh Valley homes
Nearly every pre-1950 house in Allentown, Bethlehem, Easton, Catasauqua, and the Slate Belt boroughs has steel or wood basement windows set in stone or block, and most are past saving. Freeze-thaw cycles pop the glazing, the steel rusts, and the wells fill with leaves. In mid-century ranches across Whitehall and Palmer, the basement units are often aluminum sliders that fog and stick. When homeowners in the Valley finish a basement, the egress question comes up immediately, and a good installer will quote the compliant opening along with the hoppers.
Hopper and Basement window questions
Do basement windows really need replacing?
If they are original steel or wood, almost always. Rusted or rotted frames leak air year-round, let water in during storms, and give insects and rodents a way in. Because basement openings are small and few, they are one of the most effective upgrades relative to the effort, and replacing them alongside the rest of the house means one measuring visit and one install. Ask for them on the same written quote.
What is a hopper window?
A short, wide window hinged at the bottom that tilts inward from the top. It is the standard style for window wells because it does not swing outward into the well. Modern hoppers latch with compression seals and are usually vinyl, which does not rust or rot like the steel and wood units they replace. Many can be removed from the frame for cleaning.
How do basement windows attach to a stone or block wall?
Older homes have a wood buck, a frame set into the masonry, that the window fastens to; newer ones may have a steel or vinyl buck. If the buck is sound, the new unit attaches to it. If it is rotted, the installer removes it and sets a new treated or vinyl buck, then seals the perimeter. The quote should state which applies at each opening.
Can I get an egress window for a basement bedroom?
Yes. Egress generally means a clear opening large enough to exit, plus a properly sized well if the window is below grade. Installers usually quote a slider or casement of the needed size, sometimes with a new well and cover. Rules are set by code and depend on the room, so ask the installer to confirm the requirement with the local code official and to put the specific opening on the quote.
Will new basement windows reduce condensation and musty smells?
They help. Insulated low-E glass stays warmer on the inside surface so moisture is less likely to condense on it, and a sealed frame stops the air and water that feed mold. A basement that still smells damp after new windows usually has another moisture source, which the installer can often point to during the measuring visit.
