What do wooden window frames cost and what should you pay attention to?

1. What are the advantages of wooden frames compared to plastic or aluminum?

Wood offers a warm, authentic look, is easy to repair and very suitable for renovation projects in older or characteristic homes. Wooden frames are also flexibly adaptable (sizes, colors, detailing) and can be perfectly combined with modern insulation standards. With good maintenance, wooden frames last 40 to 60 years.

2. How often should wooden frames be maintained?

That depends on the finish and the weather influences. Professionally painted frames need repainting on average every 6 to 10 years. Transparent stain or oil finishes require more frequent maintenance. Low-maintenance wood types (such as accoya) require less frequent treatment.

3. Which wood types are common in outdoor applications?

Frequently used wood types are:

• Meranti: standard, durability class II, easy to process
• Mahogany: stable and beautifully even, higher price range
• Oak: robust and classic, especially for rural homes
• Accoya: modified wood with very high durability (class I)

The final choice not only affects the price, but also the maintenance interval and appearance.

4. Are wooden frames eligible for subsidy?

Yes, provided you combine wooden frames with HR++ or HR+++ insulating glass and have the work carried out by a recognized company. In 2025, the ISDE scheme applies with subsidies of up to €222 per m² for triple glazing in combination with other insulation measures. You must apply for the subsidy yourself via the Rijksoverheid.

5. Are wooden frames suitable for triple glazing (HR+++) and soundproof glass?

Yes, but the frame must be suitable for thicker glass construction. This requires adapted profiles, sturdier fittings and careful assembly. The costs are higher, but the insulation value and noise reduction improve considerably.

6. What about the warranty on wooden frames?

Professional suppliers generally give:

• 10 year warranty on the frame wood
• 10–15 year warranty on HR++ or HR+++ glass
• 5–10 year warranty on assembly and finishing

The condition is that the frame has been installed correctly and is regularly maintained.

7. What is included in a standard quote for wooden frames?

A complete quote usually includes:

• Custom frame (primed or painted)
• HR++ glass with spacer and filling
• SKG** hardware
• Removing old frame
• Assembly, finishing, sealing and disposal
• VAT and any ventilation grilles

Please note: interior finishing or painting on the inside is not always included. You should check this in the specification of the quote.

8. Can I choose different colors for the inside and outside?

Yes, but this entails an additional cost, especially with factory-finished frames. Many suppliers offer a wide range of RAL colors or transparent finishes. A different color on the inside costs an average of € 150 – € 250 extra per frame.

9. What is the delivery time of wooden frames?

On average, the delivery time is between 6 and 10 weeks, depending on the chosen type of wood, finish, dimensions and how busy the supplier is. This may be faster for standard sizes; for special profiles or colors it can take up to 12 weeks or more.

10. What should I pay attention to when comparing quotes?

Pay particular attention to:

• Material choice (type of wood and finish)
• Type of glass (HR++, HR+++ or special glass)
• Including or excluding interior finishing
• Specification of ventilation grilles, hardware and paintwork
• Clear mention of assembly costs and guarantees

Average cost of wooden frames per house type

Price-determining factors

• Wood type: Meranti is common, but oak, afzelia or accoya are more expensive.
• Finish: Primer is standard; lacquered frames or special colors are more expensive.
• Glazing: HR+++ glass or safety glass increases the price considerably.
• Ventilation facilities: Grilles or small hinged windows increase the total price per frame.
• Installation situation: Frames on a floor, in a dormer or difficult to reach facade involve additional labor costs.
• Interior finishing: Finishing with a cove, windowsill connection or stucco repair often counts separately.

jeofferte.nl distributes your request among recognized woodworkers and carpentry companies with experience in wooden frames. Compare the received quotes on quality, detailing and finishing to make the right choice.

Explanation by window type

Fixed window

The simplest type of frame, with no moving parts. Ideal for fixed facade sections or large glass areas.
Most affordable option, suitable for HR++ or HR+++ glass.

Tilt-and-turn window

Popular due to its ventilation position. More expensive than fixed windows due to fittings, hinges, and milling.
Surcharge on price due to extra hardware and fittings.

Combination frame

Consists of a fixed part and a tilt-and-turn part in one wooden frame.
Popular for larger windows or for combined functions (view + ventilation).

Fanlight

Small window that tilts inwards or outwards, often used as a transom window in toilets, bathrooms or hallways.
Compact and relatively inexpensive, but with moving parts.

Double casement window

Two sashes that rotate inwards or outwards. A beautiful solution for rural or classic facades.
Customization required, higher price due to double technique and finish.

Sliding window

Horizontally sliding sash, with higher requirements for precision, rails and running mechanism.
Relatively expensive, but space-saving and visually attractive.

Panoramic window

Large, fixed window with maximum daylight. Often as a facade-wide element.
Price is influenced by the weight of the glass and the need for extra strong frame profiles.

What is included in these prices?

• Fully custom hardwood frame (meranti or similar, class II)
• HR++ glass with insulating properties (U-value approx. 1.1 W/m²K)
• SKG-certified hardware on opening parts
• Full installation, including demolition of existing frame
• Interior finishing (finishing strips or windowsill connection)
• Topcoat or primer finish (depending on specification)
• Sealing and installation work, in accordance with building standards
• VAT (21% on materials, 9% on labor for renovation of homes older than 2 years)

Influence of glass choice

Glass type	Surcharge per frame (indicative)
HR++ (standard)	included
HR+++ (triple glazing)	€ 250 – € 400
Safety glass	€ 180 – € 300
Soundproof glass	€ 200 – € 350

HR+++ glass requires a thicker rebate, more rigid profiles, and heavier mounting. For large glass surfaces, measurement of strength and load-bearing capacity is essential.

Additional costs per option (if applicable)

Option	Indicative additional cost per frame
Ventilation grille (basic)	€ 80 – € 130
Ventilation grille (self-regulating)	€ 120 – € 180
Inside/outside in different colors	€ 150 – € 250
Burglar-resistant hardware SKG***	€ 100 – € 250
Lacquered finish (color)	€ 75 – € 125 per side

Why do prices vary?

Price differences between professional companies arise due to, among other things:

• Difference in chosen wood type (meranti vs. oak vs. accoya)
• Production method (standard profile vs. CNC custom work)
• Level of finish (primer or factory lacquer)
• Assembly conditions (floor, accessibility)
• Included services (interior finishing yes/no, transport, removal)

Important considerations

• When using HR+++ or soundproof glass, the wooden frame must be fitted with adapted profiles or thicker glazing beads.
• Ventilation grilles are often required when replacing without mechanical ventilation in the home.
• Most frames are supplied with a standard primer; factory finishing provides better durability, but increases the price.
• For larger projects (multiple frames), bundle discounts on extra options often apply.

jeofferte.nl offers clients the opportunity to see exact additional costs per option in the quotes from professionals. This provides insight per facade part or window position, tailored to glass requirements, function and use.

1. Wood type

The type of wood significantly influences the price. The more durable and stable the wood, the higher the cost. Commonly used wood types are:

2. Finishing and paint treatment

Frames with primer are the cheapest as standard. If you want a ready-lacquered product in a specific RAL colour (or different inside/outside), the price will increase due to additional labour and drying time.

• Primer: included as standard
• Single-sided finish: + € 75 – € 125 per frame
• Double-sided finish (colour inside ≠ outside): + € 150 – € 250 per frame

3. Frame / window function type

Fixed windows are cheaper than tilt-and-turn windows, sliding windows or doors. More moving parts mean more hardware, more work, and different profiling.

4. Glazing

The choice of HR++, HR+++, safety glass, or sound-insulating glass directly impacts the price. Thicker glass also requires stronger and more expensive frames.

5. Ventilation grilles

Ventilation grilles are desirable or required, especially for fixed or large windows. Depending on the length and type, the additional cost varies:

• Basic ventilation grille: € 80 – € 130 per meter
• Self-regulating grille: € 120 – € 180 per meter

6. Hinges and locks

SKG** is usually included. SKG*** (with anti-burglary protection) or additional locks increase the price per frame or door by an average of € 100 – € 250.

7. Installation conditions

Accessibility, working height, and the condition of the existing frame can increase labor costs. Some factors influencing the price:

• Recessed window frames: extra labor and/or scaffolding
• Dormer, bay window, or extension: custom work and limited access
• Rotten wood or damage to existing connections: additional work

8. Interior finishing

Not always included, but often desired. For example, paneling, connection to an existing windowsill, or repair of plasterwork.

• Standard finish (slats): included or € 100 – € 150 per frame
• Custom or repair: depending on the situation on site
