Window Replacement in Hanover, MD

Hanover's homes are young by Maryland standards — the townhomes and single-family houses of Arundel Preserve, the Reserve at Arundel Preserve, Oxford Square, Two Rivers, and Parkside mostly went up in the 2000s and 2010s near Arundel Mills, where the 21076 ZIP straddles Anne Arundel and Howard counties. That youth fools people into thinking the windows are fine, but the builder-grade double-hungs installed during that boom were the cheapest units that met code, and fifteen-plus years of Maryland summers and winters have taken their toll: seals are starting to fail, you'll spot fog between the panes, sashes stick, and the thin glass packages let heat pour out of end units and top floors.

We replace them with ENERGY STAR-rated windows chosen for how each home is built and how it faces. For most Hanover townhomes and single-family homes that means double-hung or casement units with Low-E glass and argon fill, installed as inserts where the builder's frames are still square and sound, or full-frame where they aren't. On the tall, sun-exposed elevations common in these newer developments, the right Low-E coating cuts solar heat gain so upstairs bedrooms stop overheating in July. Every opening is flashed and foam-sealed — the same detail rushed builder crews often shortcut — so the new window actually delivers the efficiency on its label and your BGE bill reflects it.

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. Because Hanover sits across the county line, we pull permits from whichever jurisdiction your address falls under, and we coordinate with your HOA on approved window styles and grille patterns in the planned communities so your replacement clears review the first time. Before we quote, we measure every opening and note which frames can take an insert versus a full-frame replacement, then put that in writing so there are no surprises on install day. Apper Construction has been family-owned since 2016 and installs with its own W-2 crews on every Hanover job, so the crew replacing the windows in your Arundel Preserve or Oxford Square home is accountable to the same warranty we hand you — not a rotating cast of subcontractors.

Most Hanover 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 $28,000 depending on size, glass package, and full-frame versus insert.
