Wood Windows: Cost per Window, Clad Wood Options, Maintenance and Lifespan

Solid wood, clad wood and wood-interior hybrids

Most "wood windows" sold today fall into one of three builds, and the build decides how much upkeep you sign up for.

Solid wood

The whole frame and sash are wood, inside and out, and the exterior is primed and painted or stained. This is the traditional window and the type most common in older neighborhoods. HomeGuide notes wood is common in homes in historical districts, and ENERGY STAR says wood frames are generally favored in historic neighborhoods.

Clad wood

The interior is wood, but the exterior faces are wrapped in a protective skin. The Efficient Windows Collaborative describes vinyl and aluminum cladding as a permanent weather-resistant surface that lowers maintenance while keeping the wood finish indoors. Fixr adds fiberglass to the list of cladding materials. The trade-offs are a higher material price and fewer color choices, since claddings are generally sold in a limited palette.

Hybrids

Some manufacturers bond an interior wood element to an exterior fiberglass element, or put a wood veneer over another material. These look like wood from inside the room, while the outside face is a different material. Ask for the product series so you know which you are buying.

Price by window type

The style of window moves the price more than anything else. Fixr's figures per wood window:

Small, simple windows sit at the bottom. Bay and bow units need several installers to lift and set, which is why they reach the top of the range.

Price by wood species

The species changes both the price and how well the window resists weather. Fixr's ranges:

Pine and Douglas fir are the budget choices. Fixr says the hardwoods generally last longer and stand up to weather better, which matters most on a solid wood window with no cladding.

Other line items on a wood window quote

Beyond the window itself, Fixr lists several costs worth checking for in each bid:

• Labor of $150 to $300 per window, more for large units or second-floor openings.
• Disposal of the old windows at $50 to $200, if not already included.
• A permit, typically $50 to $300.
• A few hundred dollars more if the wall opening has to be resized.
• Repairs to hidden rot, mold or pest damage found once the old window is out, which can add hundreds or thousands.

Ordering ten or more windows at once can bring the per-window price down by about 20%, according to Fixr. Installers are busiest in spring and summer, so a fall install may price lower.

How well wood windows insulate

Wood is a natural insulator. The Efficient Windows Collaborative gives wood frames U-factors of about 0.30 to 0.50, far better than the roughly 1.0 to 2.0 it gives aluminum. ENERGY STAR lists wood among frames that provide good insulation.

Wood has one limit: a solid frame has no hollow cavities to fill with foam, the way vinyl and fiberglass profiles do. Manufacturers improve wood windows instead with thicker frames, by avoiding metal parts that bridge the inside and outside, and with low-conductance spacers between the panes. As with any frame, the glass package drives most of the rating, so compare NFRC labels between quotes. Our energy-efficient windows guide explains those numbers.

Lifespan depends on keeping water out

Fixr puts wood window lifespan at up to 60 years, and its comparison table gives 30 to 60. The Efficient Windows Collaborative is blunt that wood is not intrinsically the most durable frame material because it can rot. Well-built, well-maintained wood windows can last a very long time. Neglected ones fail early.

The National Park Service, in its guidance on historic wood windows, names moisture as the primary cause of decay. It points to the places water collects first:

• The sill, especially its underside.
• The joints where the sill meets the side jambs.
• The lower corners of the bottom sash rail.
• Muntin joints, where the small bars between panes meet.

Peeling, blistering or cracked paint usually marks where water is getting in. NPS cautions that failing paint does not by itself mean the wood underneath is bad. A simple probe test with a sharp tool shows whether the wood is solid or soft below the surface.

A maintenance routine that works

• Inspect paint and caulk regularly and touch up failures before water soaks in.
• Keep glazing putty intact, since cracked putty lets water into the sash.
• Repaint exterior wood on a regular cycle; paint is the frame's weather barrier.
• Choose clad wood for elevations that take the worst sun and rain if you want to paint less.

Repair or replace?

Old wood windows are often repairable, and repair usually costs much less. Fixr puts the average window repair at about $400, compared with about $1,200 for a new wood window.

The National Park Service describes a standard repair sequence: remove loose paint, take out and reglaze the sash, repair the frame, add weatherstripping, reinstall and repaint. Partly rotted wood can be consolidated with semi-rigid epoxy, filled with epoxy patching compound, then sanded and painted. Replacement makes more sense when large sections are badly decayed, many windows have failed, or you want modern insulated glass throughout.

If your house is in a historic district, check local review rules before ordering. The Secretary of the Interior's Standards, which NPS applies, call for repairing original windows where possible and replacing them in kind when they cannot be saved.

Do wood windows pay off at resale?

Partly. HomeGuide's summary of Cost vs. Value data puts a wood window replacement project at $24,376, adding $14,912 in resale value, a 61.2% return. Vinyl replacement returned a higher 68.5% on a lower cost, but wood added the larger dollar amount. Match the window to the neighborhood: in a market of historic or high-end homes, buyers may expect wood.

Pros and cons of wood windows

Points in favor:

• Warm, natural look inside that other materials only imitate.
• Good insulation, with frame U-factors around 0.30 to 0.50.
• Repairable, part by part, for decades.
• Expected in many historic districts.
• Can be painted any color, and repainted later.

Points against:

• Highest upfront cost of the common frames.
• Exterior paint needs regular attention, or rot sets in.
• Clad versions limit exterior colors and add cost.
• Lower percentage return at resale than vinyl.

Wood compared with other frames

Installed costs are from HomeGuide except steel (Angi). Lifespans are from Fixr except steel (Angi). Clad wood pricing comes from Fixr's note that cladding adds to material cost.

For a lower-maintenance wood look, compare fiberglass windows. For the lowest price, see vinyl windows. If you are drawn to slim modern frames, read about aluminum windows and steel windows.
