Window Replacement Costs
How much does window replacement cost in Ottawa?
Window replacement in Ottawa typically costs $400-$1,500 per window installed, depending on size, style, and glass options. A standard double-hung vinyl window runs $500-$800 installed. Triple-pane and specialty shapes cost more. Most homes with 10-15 windows budget $8,000-$15,000 for a complete replacement project.
Is it cheaper to repair or replace windows?
Repair makes sense for minor issues like weatherstripping, hardware, or single-pane glass replacement ($100-$300 per window). Replace when you see condensation between panes (seal failure), rotted frames, or single-pane glass without storm windows. Failed seals and structural damage typically cost more to repeatedly fix than replacing once with quality windows.
What is the price difference between double and triple-pane windows?
Triple-pane windows cost 15-25% more than comparable double-pane units—roughly $100-$200 extra per window. In Ottawa's climate with -25°C winters, triple-pane provides noticeably better comfort and energy savings, often paying for the upgrade within 7-10 years through reduced heating costs.
Do window replacement costs include installation?
Our quotes always include complete professional installation—removal of old windows, installation of new units, insulation, interior and exterior trim, and cleanup. Some companies quote products separately from labor. We believe all-inclusive pricing helps you budget accurately without surprises.
How much can I save on energy bills with new windows?
Replacing single-pane or failed double-pane windows typically reduces heating costs by 15-25%. For a home spending $2,500/year on heating, that's $375-$625 annual savings. ENERGY STAR certified triple-pane windows in Ottawa homes often see even higher savings, especially in older homes with drafty windows.
Window Types & Selection
What is the best type of window for Ottawa homes?
For Ottawa's extreme temperatures, casement and awning windows with compression seals provide the tightest seal against air infiltration. Double-hung windows work well with proper weatherstripping. Choose triple-pane glass, Low-E coating, and argon fill for maximum energy efficiency in our climate zone 6.
What is the difference between vinyl and fiberglass windows?
Vinyl windows cost less and offer good insulation but can expand and contract more with temperature swings. Fiberglass windows cost 15-30% more but handle Ottawa's temperature extremes better, don't warp, and can be painted. Both outperform aluminum in energy efficiency.
Are triple-pane windows worth it in Ottawa?
Yes. Ottawa winters regularly hit -20°C to -30°C. Triple-pane windows with argon fill and Low-E coatings keep interior glass surfaces warmer, eliminating cold drafts and condensation. The comfort improvement and energy savings justify the added cost, especially for north-facing windows.
What is Low-E glass and do I need it?
Low-E (low emissivity) glass has a microscopic metallic coating that reflects infrared heat while allowing visible light through. In winter, it keeps heat inside. In summer, it reduces solar heat gain. For Ottawa homes, Low-E is standard on quality windows and provides measurable energy savings.
Should I choose argon or krypton gas fill?
Argon provides excellent insulation at lower cost and is standard in quality double and triple-pane windows. Krypton offers better insulation in thinner spaces but costs more. Most Ottawa homeowners find argon-filled windows provide ideal performance for the investment.
Door Installation
How much does a new entry door cost installed in Ottawa?
Entry door installation in Ottawa ranges from $1,500-$5,000 including the door, hardware, weatherstripping, and labor. Steel doors start around $1,500-$2,500, fiberglass doors run $2,000-$4,000, and wood doors cost $3,000-$5,000+. Sidelights and transoms add to the cost.
What is the best material for an entry door in Ottawa?
Fiberglass offers the best balance for Ottawa: it won't warp, crack, or dent like wood can, insulates better than steel, and comes in realistic wood-grain finishes. Steel doors provide excellent security at lower cost but can dent and feel cold. Wood doors look beautiful but require more maintenance.
How long does it take to install a new front door?
A standard entry door replacement takes 4-6 hours for one experienced installer. If the rough opening needs adjustment, framing repair, or significant rot remediation, allow a full day. We typically schedule one door per day to ensure proper installation without rushing.
Do I need a permit to replace my front door?
No permit is needed in Ottawa for a standard door replacement where the opening size stays the same. If you're enlarging the opening, adding sidelights, or making structural changes to the wall, a building permit is required. We handle permit applications when needed.
What should I look for in a patio door?
Choose a patio door with multi-point locking for security, Low-E glass for energy efficiency, and a thermal break in the frame to prevent condensation. Test the sliding or swinging action—quality doors operate smoothly without sticking. Built-in blinds are convenient but limit replacement options if they fail.
Energy Efficiency & Rebates
What rebates are available for window replacement in Ontario?
The Canada Greener Homes Grant offers up to $5,000 for energy efficiency upgrades including windows and doors. You must complete a pre-retrofit EnerGuide evaluation, then a post-retrofit evaluation after installation. ENERGY STAR certified products with specific U-values are required. We help coordinate the process.
What does ENERGY STAR certification mean for windows?
ENERGY STAR certified windows meet Natural Resources Canada efficiency standards for our climate zone. In Ottawa (Zone 6), windows must have U-factor of 1.22 or lower. These windows reduce energy consumption compared to standard products and qualify for rebate programs.
How do I know if my windows need replacement?
Replace windows when you notice: condensation between panes (seal failure), visible rot in wood frames, difficulty opening or closing, noticeable drafts even when closed, single-pane glass without storm windows, or fog that won't clear. These issues worsen over time and increase energy costs.
Will new windows reduce my hydro bill?
Yes, though most savings come from reduced heating (gas or oil) costs. New windows also reduce air conditioning costs in summer by blocking solar heat gain. Overall, expect 10-25% reduction in heating and cooling costs depending on your current windows' condition.
What is the U-factor and why does it matter?
U-factor measures how well a window insulates—lower numbers mean better insulation. In Ottawa, ENERGY STAR requires U-factor of 1.22 or lower. High-performance triple-pane windows achieve 0.9-1.1 U-factor. Compare U-factors when shopping; a window with 1.0 U-factor insulates better than one with 1.4.
Installation Process
What is the difference between full-frame and insert window replacement?
Full-frame replacement removes the entire window including the frame down to the rough opening—necessary when frames are damaged or you want to change window style. Insert replacement fits new windows into existing frames, preserving trim and siding. Inserts cost less and work faster when frames are sound.
How long does it take to replace windows in a house?
An experienced crew replaces 8-12 windows per day for standard insert installations. A typical 10-15 window home takes 1-2 days. Full-frame replacements take longer—roughly 4-6 windows per day. We schedule projects to complete your home efficiently without leaving windows unfinished overnight.
What happens to my old windows?
We remove and dispose of all old windows, frames, and debris as part of every installation. Windows are disposed of responsibly—glass and aluminum are recycled where possible. Your home is left clean with no debris from the project.
Can windows be replaced in winter?
Yes, we install windows year-round. Each window opening is exposed for only minutes during the swap. We work one window at a time and have the new unit ready to install immediately. Indoor temperatures drop minimally. We avoid installation during extreme cold snaps below -20°C.
Will you damage my walls or trim during installation?
We take great care to protect your home. For insert installations, existing interior trim typically stays in place. Full-frame work requires removing and reinstalling trim—we label and store pieces carefully. We use drop cloths, protect floors, and clean up completely after each window.
Window Styles & Features
What is the best window style for ventilation?
Casement windows (hinged to swing outward) provide the most ventilation—100% of the opening is usable when fully open. Awning windows (hinged at top) work well for ventilation even during light rain. Double-hung windows offer less airflow but allow flexible top or bottom opening.
Should I get windows with grids or grilles?
Grids between the glass (GBG) are easiest to clean—the glass surfaces are smooth. Surface-applied grids on the interior offer a more traditional look but require more cleaning effort. For heritage homes or traditional styles, grids add architectural character. Modern homes often skip them.
What is a picture window and when should I use one?
Picture windows are fixed (non-opening) windows that maximize views and light. They're more energy efficient than operable windows because there are no moving parts to leak air. Use picture windows for living rooms, stairwells, or any location where you want maximum glass without ventilation needs.
Can I get different window styles in the same room?
Yes, mixing styles is common and practical. A popular combination pairs a large fixed picture window in the center with smaller operable casement or double-hung windows on the sides. This maximizes light and views while still providing ventilation options.
What tint options are available for windows?
Beyond clear glass, options include bronze, grey, and reflective tints that reduce glare and solar heat gain. Tinted glass is useful for south and west-facing windows that get intense sun. Low-E coatings provide similar benefits without changing the glass appearance.
Bay & Bow Windows
What is the difference between bay and bow windows?
Bay windows have three panels at defined angles, creating a more angular projection. Bow windows use four or more panels in a gentle curve. Bay windows often have a larger center picture window flanked by smaller operable windows. Bow windows create a softer, more rounded appearance.
Do bay windows need special support?
Yes, bay and bow windows project beyond the wall and need structural support. Options include cable systems anchored to the wall above, knee brackets underneath, or a full roof structure. We assess your situation and install appropriate support that's both functional and attractive.
How much do bay windows cost compared to standard windows?
Bay and bow windows cost $3,000-$12,000 installed, compared to $400-$1,500 for standard windows. The higher cost reflects multiple window units, structural framing, interior seat board, exterior roofing or cladding, and more complex installation. They add significant architectural value.
Can I add a bay window where there isn't one now?
Yes, we can install new bay windows by enlarging an existing window opening. This requires structural work, permit approvals, and exterior finishing. The cost is higher than replacement, but bay windows add both living space and curb appeal that many homeowners find worthwhile.
Weather & Maintenance
How do I prevent condensation on my windows?
Interior condensation means indoor humidity is high. Run bathroom and kitchen exhaust fans, ensure proper ventilation, and consider a dehumidifier. Condensation between panes indicates seal failure—the window needs replacement. Exterior condensation on very cold mornings is normal and indicates the window is insulating well.
How often should windows be replaced?
Quality vinyl and fiberglass windows last 20-30 years. Wood windows with good maintenance can last longer, but many older wood windows have failed seals or single-pane glass. If your windows are over 15-20 years old and showing drafts, condensation, or operation problems, replacement is worth considering.
Do vinyl windows need maintenance?
Vinyl windows need minimal maintenance—just occasional cleaning with soap and water. Don't paint vinyl; it can affect expansion and contraction. Check weatherstripping every few years and replace if worn. Lubricate tracks and hardware annually with silicone spray. No staining or sealing required.
What warranty should I expect on new windows?
Quality windows carry lifetime warranties on vinyl frames and 20-year warranties on glass seals. Read the fine print—some warranties are prorated or don't cover labor. We offer workmanship warranties on our installation and work with manufacturers to resolve any product issues during the warranty period.
How do new windows handle Ottawa's extreme temperatures?
Modern vinyl and fiberglass windows are engineered for thermal expansion from -40°C to +40°C—Ottawa's full range. Multi-chamber frames provide insulation, and flexible seals maintain tight contact as materials expand and contract. Quality windows operate smoothly year-round without binding or sticking.
