Ellicott City's housing runs the full range of Howard County — 1960s–1980s split-levels and colonials climbing the hills around Font Hill, Dunloggin, and Valley Mede, newer construction out toward Turf Valley, and the older, character homes tucked near historic Main Street and the Patapsco. What ties them together is windows that are due. The original aluminum and early vinyl units on the mid-century homes have lost their seals — you can see the fog between the panes — and they leak heat in January and cooling all summer, driving BGE bills up on some of the largest, most exposed elevations in the county.

We replace them with ENERGY STAR-rated windows matched to how the house is built and how it faces. For most Ellicott City homes that means double-hung or casement units with Low-E glass and argon fill, in a full-frame or insert installation depending on whether the existing frames are still sound. On the west- and south-facing hillside elevations that take the afternoon sun, we spec the Low-E coating that cuts solar heat gain so the upstairs bedrooms stop baking. Every opening is flashed and foam-sealed so the new window performs the way the label promises — a window is only as good as the water-and-air seal around it, and that's where cheap installs fail first.

Every project is installed by our own W-2 crews, never subcontracted, and backed by a written workmanship warranty separate from the manufacturer's glass warranty. We pull Howard County permits, and for the older homes near the historic district we're careful to match sightlines and grille patterns where it matters. Before we quote, we measure every opening and note which frames can take an insert versus a full-frame replacement, and we put that in writing so there are no surprises on install day.

Most Ellicott City window projects run $650–$1,400 per window installed for standard double-hung or casement units, with bay, bow, and specialty shapes higher. Whole-home replacements of 10–20 windows typically land between $9,000 and $26,000 depending on size, glass package, and full-frame versus insert. You get a written, per-window estimate before scheduling. Call 410-508-6141.

Windows in Ellicott City — Common Questions

How much does window replacement cost in Ellicott City, MD?

Most standard double-hung or casement windows run $650 to $1,400 each installed in Ellicott City. Bay, bow, and specialty shapes cost more. A whole-home replacement of 10–20 windows usually lands between $9,000 and $26,000 depending on size, glass package, and full-frame versus insert install.

Full-frame or insert replacement — which do I need?

It depends on the existing frame. If the frame and sill are still sound, an insert (pocket) replacement is faster and less invasive. If there's rot or you want to correct old air leaks, full-frame replacement is the right call. We inspect and note it per opening in writing before you decide.

Will new windows actually lower my BGE bill?

On the mid-century Ellicott City homes with failed aluminum or early vinyl windows, yes — noticeably. ENERGY STAR Low-E glass with argon fill stops the heat loss and solar gain those old single- and failed double-pane units let through, especially on the large west- and south-facing hillside elevations.

Can you match windows on an older home near Main Street?

Yes. On the older, character homes near the historic district we match sightlines and grille patterns where it matters, and we pull the proper Howard County permits. If a property falls under historic-review rules, we'll flag that before the order goes in.
