Basement window replacement is no longer just a cosmetic upgrade. With evolving energy codes, storm-resistant requirements, and a growing demand for healthy indoor air, the choice of casing material is now mission-critical. Steel casing delivers unmatched durability and weather-tight performance—qualities that resonate with Boston’s freeze-thaw cycles and New England’s coastal moisture. CountBricks has spent the last decade perfecting the workflow to replace basement windows steel casing in occupied homes, minimizing disruption while maximizing ROI for homeowners and property investors.
Replacing a basement window involves more than swapping glass. The process includes:
1. Removing deteriorated wood or vinyl units
2. Addressing potential structural rot at the sill plate
3. Installing new galvanized or stainless steel casing with integrated thermal breaks
4. Flashing and air-sealing to exceed current IECC standards
5. Finishing interior trims and exterior masonry interfaces
CountBricks manages every component through our AI-powered estimating engine, ensuring no hidden tasks are overlooked.
Picture this: you walk your basement with a phone in hand, describing each window. Our platform converts your real-time voice notes into a detailed line-item estimate—materials, labor, and local permit fees—within seconds. No more back-and-forth emails or missed dimensions.
Key advantages
• Instant clarity on project cost drivers
• Automatic selection of steel casing profiles sized to your rough openings
• Live sync with regional material suppliers to reflect today’s steel pricing
If you already have architectural plans or an inspection report, simply upload the PDF to CountBricks.com/services. Our blueprint AI traces masonry openings, converts them to quantities, and pairs them with steel casing SKUs in minutes. This keeps your project on schedule even when city approvals shift.
• Entry-level egress window (32" x 48") with galvanized casing: $1,450 – $1,850 per unit
• Premium stainless steel casing with low-E glazing: $2,050 – $2,650 per unit
• Add-on interior trim package (paint-ready MDF): $180 – $275 per opening
All figures are updated every morning via CountBricks’ live materials feed, so there are no post-contract surprises.
1. Permitting and call-before-you-dig: 3–5 business days
2. Demolition and rough opening prep: 1 day
3. Steel casing installation and flashing: 1 day
4. Insulation, air-seal, and trim finish: 1 day
5. Final punch list and inspection sign-off: 1 day
Even multi-window basements average under a week from start to finish with a CountBricks crew.
Steel is an excellent structural material, yet it can be a thermal bridge. CountBricks specifies insulated thermal blocks and low-conductivity fasteners to eliminate cold spots. We also integrate self-adhered flashing membranes that tie into your existing drainage plane, preventing the condensation that often plagues older New England foundations.
Basement windows doubling as emergency egress must meet specific clear-opening dimensions. CountBricks’ AI engine references Massachusetts Residential Code section R310 automatically, flagging any non-compliant openings during the estimate stage—saving costly rework down the line.
A landlord needed to legalize a basement apartment by upgrading four 1950s steel hopper windows. Using CountBricks’ voice walk-through, the entire scope was priced in under five minutes. The project included galvannealed steel casings, tempered low-E glass, and brick-mould extensions to match the historic façade. Installation took three days, and blower-door tests showed a 21% improvement in ACH50. View more details at CountBricks.com/portfolio.

Homeowners often assume steel casing limits design freedom. CountBricks proves the opposite. Our fabrication partners laser-cut custom profiles, allowing curves, flanges, and integrated brick moulds that blend seamlessly with Victorian rowhouses or modern townhomes.
1. Triple-Pane IGUs: Boost your window’s overall R-value by up to 40 % while deadening street noise for basement media rooms.
2. Factory-Applied Powder Coatings: Select from over 200 colors with coastal-grade corrosion resistance, extending repaint cycles to 25+ years.
3. Integrated Smart Sensors: Optional magnetic contact sensors tie into CountBricks’ smart-home ecosystem, alerting you to forced entry or abnormal humidity.
• Precision Saw-Cutting: Instead of hammer-chipping masonry, we deploy track saws with HEPA extraction, reducing dust by 93 % and safeguarding indoor air quality.
• Pre-Fabricated Flashing Kits: All sill pans and head flashings arrive CNC-folded to exact sizes, eliminating jobsite improvisation.
• AI-Guided Punch Lists: Technicians scan a QR code at completion; our app cross-checks fastener patterns, insulation depth, and caulk bead continuity before the site is marked ready for inspection.
