Window Replacement Cost Factors
Window replacement costs in Baltimore, Maryland, range from $215 to replace one window to over $14,995 to upgrade all the frames and panes in your home. Here’s how to budget for your specific project requirements.
Number of Windows
Window replacement costs in Baltimore, Maryland, average $630 per window, and the average house has eight to 15 windows. Baltimore is known for having a high proportion of attached row houses, so your home’s window numbers may be on the lower side. The average cost to replace eight windows in Baltimore, Maryland, is $4,530 to $5,540.
| Number of Windows | Price Range |
|---|---|
| 6–8 | $3,400–$5,540 |
| 8–12 | $4,530–$8,310 |
| 12–16 | $6,800–$11,000 |
| 16–20 | $9,070–$13,860 |
| 20–24 | $11,340–$16,630 |
| 25 | $14,175–$17,325 |
Size
Popular window sizes include 38 by 48 inches and 38 by 72 inches. However, if you have a Queen Anne or Late Victorian-style historical home, which are common in Baltimore, your home may feature larger bay windows that cost more to replace. If you live in a traditional, 19th-century working-class row house, your bill will be smaller—their windows tend to be narrower, especially in the side and rear parts of the building.
| Size of Window in Inches | Average Cost |
|---|---|
| 24 x 36 | $300–$840 |
| 24 x 48 | $420–$980 |
| 36 x 48 | $560–$1,120 |
| 36 x 72 | $700–$1,400 |
| 60 x 72 | $840–$1,750 |
Material
In Baltimore, it makes sense to select moisture-resistant window frame materials that can withstand the region's high summer humidity levels and the extreme temperature fluctuations that may occur in the colder months.
The top choice is durable fiberglass. Its insulating properties help keep you cool in summer and warm in winter. Because it’s weather-resistant, it won’t warp in high humidity or when temperatures change rapidly. However, it does come with a high price tag. Vinyl, while not quite as heat-resistant, is a practical, more wallet-friendly runner-up.
| Material | Pros | Cons | Average Cost |
|---|---|---|---|
| Aluminum | Durable | Heat absorbent | $75–$400 |
| Vinyl | Energy-efficient | Warping in heat | $100–$900 |
| Composite | Heat-resistant | UV ray fading | $300–$1,200 |
| Wood | Heat-resistant | Rotting in humidity | $150–$1,300 |
| Fiberglass | Insulating and durable | High cost | $500–$1,500 |
Glass Type
Baltimore has particular regulations regarding window energy efficiency to improve building energy performance and reduce energy consumption. Current guidance stipulates that replacement windows must have a U-factor of 0.40 or less to maximize the insulating properties of the glass.
While these regulations mean you’ll have to invest in pricier double- or triple-pane glass—low-cost single-pane glass isn’t available with such a low U-factor—it does make for a better long-term investment. These insulating, energy-efficient window options can lower your energy bills, keeping your home comfortably cooler in the subtropical summers of the region and warmer in the chilly winter.
| Type of Glass | Qualities | Average Cost |
|---|---|---|
| Single-pane glass | Cost-effective and easy maintenance, but poor insulation | $100–$400 |
| Double-pane glass | Durable and heat-resistant | $300–$2,000 |
| Triple-pane glass | Highly heat-resistant, but high cost | $600–$3,000 |
| Low-emissivity (Low-E) glass | High energy efficiency, but can reduce natural light | $300–$1,100 |
Style
Below are some popular window styles for traditional and contemporary Baltimore homes, along with their average replacement costs.
| Window Type | Average Cost per Window | Qualities |
|---|---|---|
| Bay | $700–$5,500 | Common in Victorian and Queen Anne homes; offer enhanced views |
| Casement | $115–$800 | Tight seal provides excellent water resistance |
| Custom | $800+ | Perfect for non-standard window sizes or shapes |
| Double-hung | $115–$600 | Popular in Victorian row houses; top and bottom sash helps control moisture |
| Floor-to-ceiling | $500–$4,000 | Let light into modern homes; can pose privacy concerns |
| Picture | $50–$550 | Unobstructed views in contemporary homes; offers no ventilation |
| Single-hung | $80–$300 | Easy operation and timeless design; limited ventilation |
Historical Preservation Guidelines
Baltimore is known for its rich heritage and has more than 30 historic districts. If your home is in a Commission for Historical and Architectural Preservation (CHAP) district, costs can be higher when replacing windows to comply with preservation standards.
The guidelines stipulate that you shouldn't replace historic windows unless they’re deteriorated beyond repair. While the average window repair costs range between $200 and $700, extensive repairs of historic windows could cost as much as replacement.
Window Replacement Pro Costs
Learning how to install replacement windows is only a DIY project for the most handy of homeowners, so it often pays to hire a window pro in Baltimore, Maryland. However, keep these location-specific cost factors in mind to avoid unexpected budgetary surprises.
Labor
According to the Bureau of Labor Statistics, construction labor costs are similar to the national average in Maryland. Budget for a local window company to charge between $100 and $300 per window for installation.
Permits
There’s a good chance you will need to budget for the cost of a building permit for window replacement work in Baltimore, Maryland, especially if your home is in one of the historic districts. Average prices range from $50 to $200 for application and permit fees in this region.
Tipping
Consider budgeting to tip your contractor 10% to 20% of the original window replacement cost estimate if their work is exceptional, completed on time, and within budget. This will be between $340 and $1,700 if your window replacement costs in Baltimore are within the average range.
Does Window Replacement Increase Home Value?
Investing in new windows can increase your home’s value. The average return on investment for window replacement costs in Baltimore, Maryland, is between 70% and 85%. However, the exact return depends on the frame and glazing materials you select when choosing new windows, the quality of the work, and the condition of the rest of your home’s exterior.
