Window Types & Pricing
Every window style serves a different purpose. Use this guide to compare types, pricing, and performance so you can choose the right windows for each room in your Maryland home.
| Window Type | Price Range (Installed) | Best For | Energy Rating |
|---|---|---|---|
| Double-Hung | $300 – $800 each | Most popular style for Maryland homes. Both sashes tilt in for easy cleaning. Traditional look suits colonial, federal, and Cape Cod architecture. | Good to Excellent |
| Casement | $350 – $900 each | Best seal of any operable window. Crank-open design catches breezes. Ideal for hard-to-reach spots like above kitchen sinks or counters. | Excellent |
| Sliding | $250 – $700 each | Wide openings where you want maximum ventilation. No hardware protrudes, making them perfect next to walkways, patios, and decks. | Good |
| Bay / Bow | $1,200 – $4,500 each | Adds interior space, dramatic curb appeal, and panoramic views. Bay windows have 3 panels at angles; bow windows have 4-5 in a gentle curve. | Good to Very Good |
| Picture / Fixed | $200 – $600 each | No ventilation — purely for views and natural light. Excellent energy efficiency because there’s no operable seal to leak. Great for living rooms and stairwells. | Excellent |
| Awning | $350 – $800 each | Hinged at the top, opens outward to allow ventilation even during rain. Often paired above or below fixed windows for airflow without exposure. | Very Good |
| Egress Basement | $500 – $1,500 each | Code requirement for finished basements used as bedrooms. Provides emergency exit. Includes well, cover, and proper drainage for below-grade installation. | Good |
| Custom / Specialty | $500 – $3,000+ each | Arched, circular, octagonal, trapezoid, and other non-standard shapes. Perfect for gable ends, transoms, and architectural accents that define your home’s character. | Varies |
All prices include professional installation, insulation, interior/exterior trim, and cleanup. Final pricing depends on size, glass options, frame material, and accessibility.
Window Frame Materials
The frame is just as important as the glass. Each material brings different strengths in cost, durability, maintenance, and energy performance. Here is how they compare for Maryland homeowners.
| Material | Cost per Window | Lifespan | Maintenance | Energy Efficiency |
|---|---|---|---|---|
| Vinyl | $200 – $600 | 20–40 years | Zero — never needs painting or staining. Just wipe clean. | Good. Multi-chamber frames with foam insulation inserts achieve excellent ratings. |
| Fiberglass | $400 – $900 | 30–50 years | Minimal. Can be painted but rarely needs it. Will not warp, rot, or crack. | Excellent. Expands and contracts at the same rate as glass, maintaining a tight seal permanently. |
| Wood | $500 – $1,200 | 30–50+ years | High. Needs painting or staining every 3-5 years. Exterior cladding reduces upkeep significantly. | Good to Excellent. Natural wood is an inherently good insulator. Clad-wood windows combine beauty and performance. |
| Composite | $400 – $800 | 30+ years | Low. Resists rot, insects, and moisture. Does not need painting. | Very Good. Engineered materials provide consistent thermal performance across temperature swings. |
| Aluminum | $200 – $500 | 20–30 years | Zero. Strong and lightweight, but prone to condensation in cold weather. | Poor to Fair. Metal conducts heat rapidly. Thermal-break aluminum improves performance but still trails vinyl and fiberglass. |
For most Maryland homeowners, vinyl offers the best balance of cost and performance. Fiberglass is the premium choice for homeowners who want maximum durability and the tightest possible seal. Wood is ideal for historic properties or homeowners who prioritize natural beauty.
8 Signs You Need New Windows
Not sure if your windows need replacing? If you recognize any of these signs, it is time for a professional assessment. We provide free window inspections across Maryland.
Drafts & Cold Spots
If you feel cold air near closed windows during winter, the seal has failed and conditioned air is escaping. Drafts can increase heating costs by 10-25%.
Condensation Between Panes
Fog or moisture trapped between glass layers means the insulating gas seal has broken. The window can no longer insulate properly and must be replaced.
Difficult to Open or Close
Windows that stick, jam, or will not stay open indicate warped frames, failed balances, or structural shifting. This is also a safety concern for emergency egress.
Visible Rot or Frame Damage
Soft, spongy, or crumbling wood frames mean moisture has been penetrating for a long time. Rot spreads to surrounding framing and wall structure if not addressed.
High Energy Bills
If your heating and cooling costs keep rising despite normal usage, inefficient windows are often the culprit. Old windows can account for 25-30% of a home’s energy loss.
Outside Noise Infiltration
If you can clearly hear traffic, lawn equipment, or conversations through closed windows, the glass and frame are not providing adequate sound insulation.
Single-Pane Windows
Single-pane glass provides almost no insulation. If your home still has single-pane windows, replacing them is the single biggest energy upgrade you can make.
Windows Over 20 Years Old
Even if your windows look fine, 20+ year old windows lack modern Low-E coatings, gas fills, and multi-chamber frame technology. Replacing them improves comfort, efficiency, and home value.

Maryland Heating & Cooling Costs
Maryland’s position in IECC Climate Zone 4A means homeowners face both high cooling costs in summer and significant heating costs in winter. Old or inefficient windows account for 25-30% of a home’s total energy loss. By replacing outdated windows with ENERGY STAR certified models, a typical Maryland household saves $200-$600 per year on utility bills.
Federal Tax Credits (2024–2032)
Under the Inflation Reduction Act, homeowners can claim a federal tax credit of up to 30% of the cost of ENERGY STAR Most Efficient certified windows, capped at $600 per year for windows specifically. This is a direct dollar-for-dollar tax credit, not just a deduction. The program runs through 2032, so there is no rush — but qualifying windows must meet the ENERGY STAR Most Efficient criteria for your climate zone.
Maryland Energy Rebates
Beyond the federal tax credit, Maryland homeowners may qualify for additional rebates through:
- EmPOWER Maryland — Utility-sponsored rebates for energy-efficient home improvements through BGE, Pepco, Delmarva Power, and SMECO
- Maryland Energy Administration — Periodic incentive programs for residential energy upgrades
- Local utility programs — Some counties offer additional weatherization and energy efficiency incentives
Payback Period: A Real Example
Consider a Maryland homeowner who replaces 12 single-pane windows with ENERGY STAR vinyl double-hung windows at a total project cost of $8,400. With a $600 federal tax credit, the net cost is $7,800. Annual energy savings of $400-$500 per year mean the windows pay for themselves in 5-6 years — and continue saving money for the remaining 20-35 years of their lifespan. Add in the 70-75% cost recovery at resale, and the total financial return significantly exceeds the initial investment.

Window Replacement FAQ
Window replacement in Maryland typically costs $200 to $4,500+ per window depending on type, material, size, and style. Double-hung vinyl windows run $300-$800, casement windows $350-$900, sliding windows $250-$700, and bay/bow windows $1,200-$4,500 installed. Whole-home replacement for 10-15 windows ranges from $5,000-$15,000 for vinyl, $8,000-$22,000 for fiberglass, and $12,000-$30,000 for wood. We provide free, detailed estimates for your specific project.
Most individual windows are installed in 30-60 minutes for a standard pocket/insert replacement. A full-frame replacement takes 1-2 hours per window because the entire frame is removed down to the rough opening. A typical whole-home project of 10-15 windows takes 1-3 days. Larger projects with 15-20+ windows or structural modifications may take 3-5 days. We provide a clear timeline during your free estimate.
Yes, we recommend that a homeowner or authorized adult be present during window installation. Our crew needs interior access to each room where windows are being replaced, and we want you to inspect the finished work before we leave. We protect your floors, furniture, and walls with drop cloths during installation and clean up completely when done.
Maryland sits in IECC Climate Zone 4A with hot, humid summers and cold winters. The best windows for this climate are ENERGY STAR certified double-pane or triple-pane windows with Low-E coatings and argon gas fill. Look for a U-factor of 0.30 or lower and SHGC of 0.25 or lower. Both vinyl and fiberglass frames perform excellently in Maryland’s temperature swings. We recommend the specific products best suited to your home’s orientation and exposure during our free consultation.
For most Maryland homes, high-quality double-pane windows with Low-E coating and argon fill provide excellent performance at the best value. Triple-pane windows offer 20-30% better insulation and superior noise reduction, but cost 15-25% more. Triple-pane is worth the investment if your home is near a busy road, highway, or airport, if certain rooms are consistently hard to keep comfortable, or if you want maximum energy savings over the 20+ year lifespan of the windows.
Yes. Under the Inflation Reduction Act, homeowners can claim a federal tax credit of up to 30% of the cost of ENERGY STAR Most Efficient certified windows, up to $600 per year for windows specifically. The windows must meet the ENERGY STAR Most Efficient criteria for Climate Zone 4A (Maryland). This is a direct dollar-for-dollar tax credit, not a deduction. Maryland also offers additional utility rebates through EmPOWER Maryland programs. We can help you choose qualifying windows to maximize your available credits and rebates.
Pocket (insert) installation fits a new window into the existing frame, which is faster (30-60 minutes per window), less expensive, and causes minimal disruption to interior and exterior trim. Full-frame installation removes the entire window including the frame down to the rough opening, which allows for inspection of hidden damage, better insulation of the cavity, and maximum glass area. Full-frame is recommended when existing frames show rot, water damage, or are significantly out of square. We assess each window during our consultation and recommend the right approach.
Minor issues like a broken latch, worn weatherstripping, or a single cracked pane can often be repaired for $75-$300. Replacement is the better investment when you see condensation between panes (seal failure), rotted or warped frames, persistent drafts even when closed, difficulty opening or closing, or when windows are over 20 years old. A good rule of thumb: if repair costs approach 50% of replacement cost, new windows make more sense financially and deliver better long-term performance. We offer free inspections and will honestly tell you if repair is sufficient.
Yes, measurably. Homeowners who replace single-pane or older double-pane windows with modern ENERGY STAR certified windows typically save 15-30% on heating and cooling costs. That translates to $200-$600+ per year depending on your home size, current window condition, and utility rates. Maryland’s hot summers and cold winters mean windows work hard year-round, so the savings are significant. Over a 25-year window lifespan, that is $5,000-$15,000 in cumulative energy savings.
We install windows from Andersen, Pella, Marvin, Simonton, and Milgard — all industry leaders with proven track records in Maryland’s climate. Andersen offers excellent overall value, Pella provides the widest design variety, Marvin leads in premium wood and custom options, Simonton delivers strong value in vinyl, and Milgard excels in fiberglass durability. We help you choose the right brand and product line based on your home’s architecture, your performance needs, and your budget.
Yes. We install new window openings in existing walls, including structural framing, proper headers, insulation, flashing, interior and exterior trim, and drywall finishing. Adding new windows requires a building permit in Maryland, which we handle for you. New windows are a popular way to brighten dark rooms, improve ventilation, add egress to basements, or create architectural features. The cost for a new opening is typically $800-$2,500+ depending on wall type, structural requirements, and window size.
Bay and bow windows project outward from the exterior wall, creating additional interior space, a built-in window seat or shelf area, and dramatic visual impact. Bay windows typically have three panels at angles (usually 30 or 45 degrees), while bow windows have four or more panels in a gentle curve. Installation costs range from $1,200-$4,500 depending on size and materials. These windows require structural support (a cable or knee brace system) and proper head flashing and roof detail to prevent leaks. A building permit is typically required.
A standard same-size window replacement (pocket/insert installation) typically does not require a permit in most Maryland counties. However, changing the opening size, adding new windows where none existed, converting a window to a door, or installing bay/bow windows where none existed usually requires a building permit. Some historic districts have additional review requirements. Crown Remodeling handles all permit applications, inspections, and code compliance so you do not have to worry about any of it.
Vinyl frames cost 30-50% less than fiberglass and are the best value for most Maryland homeowners. They offer good energy efficiency, zero maintenance, and 20-40 year lifespans. Fiberglass frames are stronger, last 30-50 years, expand and contract at the same rate as glass for a permanently tight seal, and can be painted any color. Choose vinyl for the best value and fiberglass for premium long-term performance. Both are excellent choices — we help you weigh cost, lifespan, and performance during our free consultation.
The most energy-efficient windows for Maryland (Climate Zone 4A) are ENERGY STAR Most Efficient certified windows with triple-pane glass, dual Low-E coatings, krypton gas fill, fiberglass frames, and warm-edge spacers. These achieve U-factors of 0.15-0.20. For most budgets, double-pane windows with a single Low-E coating and argon gas fill in vinyl or fiberglass frames deliver excellent performance at a significantly lower cost. The key is choosing windows that meet at least the ENERGY STAR standard: U-Factor ≤ 0.30 and SHGC ≤ 0.40 for our climate zone.
Yes. All of the window brands we install offer custom sizing to fit non-standard openings. Custom windows typically add 4-6 weeks to the lead time and 15-30% to the cost compared to standard sizes. We take precise measurements of every opening during our free consultation to ensure a perfect fit, whether your openings are standard or unique. Many older Maryland homes have non-standard window sizes, so custom ordering is a common and routine part of our work.
Low-E (low-emissivity) glass has a microscopically thin metallic coating that reflects infrared heat while allowing visible light to pass through. In summer, it keeps solar heat outside your home. In winter, it reflects interior heat back in. For Maryland homes, Low-E glass reduces energy costs by 15-25% compared to clear glass. We strongly recommend Low-E coatings on all replacement windows — the modest additional cost of $25-$50 per window pays for itself within 2-3 years through energy savings, and it also blocks 75-95% of UV rays that fade furniture and flooring.
Yes, significantly. Modern double-pane windows reduce outside noise by 25-35% compared to single-pane windows. Triple-pane windows reduce noise by 35-50%. For homes near busy roads, highways, airports, or train lines in the Baltimore or DC metro areas, we recommend triple-pane windows with laminated glass, which provides the best sound insulation available. Frame material also matters — fiberglass and vinyl frames dampen sound better than aluminum because they do not conduct vibration.
U-Factor measures how well a window prevents heat from escaping (in winter) and entering (in summer). The lower the number, the better the insulation. For Maryland (Climate Zone 4A), ENERGY STAR requires a U-Factor of 0.30 or lower. Premium windows achieve U-Factors of 0.15-0.22. To put it in perspective: a window with a U-Factor of 0.20 loses half as much heat as one rated 0.40. When comparing windows, always look at the whole-unit U-Factor (which includes the frame), not just the center-of-glass value, since the frame accounts for 15-25% of heat transfer.
Vinyl and fiberglass windows need almost no maintenance. Clean the glass and tracks with mild soap and water twice a year. Lubricate hardware (hinges, locks, operators) with silicone spray annually. Wood windows need periodic painting or staining every 3-5 years for exposed wood surfaces. For all window types, check weatherstripping annually and replace if worn. Keep weep holes at the bottom of the frame clear of debris to ensure proper water drainage. Avoid harsh chemical cleaners, abrasive pads, or pressure washers on window frames and glass coatings.
Yes. We offer flexible financing options through our financing partners, including low monthly payments and promotional periods. Many Maryland homeowners finance whole-home window replacements to spread the cost over time while immediately benefiting from lower energy bills. Visit our financing page or call (410) 861-0039 to discuss payment options during your free estimate. We also accept cash, check, and all major credit cards.
Window replacement typically returns 70-75% of the project cost at resale, according to Remodeling Magazine’s annual Cost vs. Value report. Beyond resale value, new windows reduce energy bills by 15-30% annually, eliminate drafts and condensation, reduce outside noise by 25-50%, and significantly improve curb appeal. For a $10,000 vinyl window project, you can expect $7,000-$7,500 in added home value plus $200-$500 per year in energy savings. For Maryland homeowners planning to sell within 5-10 years, new windows are one of the highest-ROI exterior upgrades available.
