The Typical Cost Of Sash Windows You Can Expect

The average cost of sash windows in Dulwich, London, is between £ 2,000 and £4,000. The cost of installing a new sash window ranges between £600 and £1,125 per window, and the cost of repairing your sash window ranges between £150 and £800.

However, this cost may vary depending on size, material, weight, and other factors.

Factors Affecting The Cost Of Sash Windows

Now that you know the average cost of sash windows, here is the breakdown of factors that affect them:

1. The Type Of Sash Window You Choose

The type you select is the first factor influencing the cost of your sash windows. Traditional sash windows come in various forms, including double-glazed versions, bespoke designs, and energy-efficient upgrades.

• Single-glazed vs. double-glazed sash windows: Single-glazed windows are often less expensive upfront but offer inferior insulation and are more prone to draughts and heat loss. On the other hand, double-glazed sash windows provide superior energy efficiency, better soundproofing, and an improved thermal barrier, making them a worthwhile investment in the long run. The added cost of double-glazing can vary but expect to pay more than single-glazed units.
• Bespoke sash windows: For homes in Dulwich in conservation areas or listed buildings, you may require bespoke sash windows that adhere to specific design and material guidelines. This will often lead to a higher price tag due to the custom work required and the need to adhere to planning restrictions.
• Energy-efficient glass options: As energy efficiency awareness increases, many homeowners opt for premium options such as FINEO vacuum glazing or safety glass. While these features can increase the upfront cost, they offer substantial heat retention and soundproofing benefits.

2. Materials Matter

The materials used to construct your sash windows also significantly affect the cost. The quality and durability of the materials will directly influence the lifespan of your windows, so it’s essential to choose wisely.

• Timber: Traditional sash windows are made of timber, a material prized for its beauty, authenticity, and excellent insulating properties. Timber frames require regular maintenance to prevent issues such as rot or warping, which can drive up costs over time. However, timber remains popular due to its classic appeal and natural look.
• Accoya wood: For those who want the best of both worlds — durability and aesthetic appeal — Accoya wood is an excellent choice. This high-performance wood is treated for enhanced stability and resistance to weathering, making it a great investment for long-lasting windows. Accoya windows are more expensive than regular timber but are worth considering for their extended lifespan and reduced maintenance needs.
• uPVC or aluminium: Some homeowners opt for uPVC or aluminium sash windows as a modern alternative to traditional wood. These materials can offer lower upfront costs and require less maintenance but may lack timber’s traditional look and feel. If you’re working on a period property in Dulwich or a listed building, uPVC or aluminium frames might not be an option due to planning restrictions.

3. Size And Number Of Windows

The number and size of the windows in your home will directly affect the total cost. Larger or more windows generally mean more material and more time spent on installation.

For example, replacing a single, smaller sash window will cost less than replacing several large, multi-pane windows. If your property in Dulwich has multiple windows to replace, such as in a larger home or multi-storey building, the project’s total cost will increase accordingly.

4. Condition Of Existing Sash Windows

If you’re considering sash window repairs rather than a complete replacement, the condition of your current windows will influence the cost. Many older sash windows can be restored, but depending on the damage, this could require extensive work, such as replacing sashes, pulleys, or cords or addressing rot or damaged timber.

• Repair vs. replacement: The costs for sash windows that are structurally sound but need cosmetic repairs or minor adjustments will be considerably lower.

However, replacement may be necessary if the frames or sashes are beyond repair. You’ll also need to factor in additional treatments, such as draught proofing, which adds to the cost but can dramatically improve the comfort of your home.

5. Labour Costs

Labour costs can vary depending on the installation’s complexity, your property’s location, and the window fitters’ experience. Sash window installation requires expertise to ensure the windows are functional and secure, so hiring skilled craftsmen is necessary.

6. Additional Features And Customisation

Additional features can add to the cost of your sash window project, but they may be well worth the investment. For example:

• Sash window shutters: Shutters are a fantastic way to enhance the functionality and aesthetics of your home. They offer extra privacy and light control and add a touch of classic style.
• Secondary glazing: If you live in a particularly noisy area of Dulwich or want to increase insulation without entirely replacing your windows, consider secondary glazing. This option adds a second layer of glass to your existing sash windows, offering additional soundproofing and thermal benefits at a lower cost than complete replacements.
• Decorative detailing: If your home is in a conservation area or has historical significance, you may need windows with detailed architectural elements. Custom designs and finishes can add to the overall cost, but they will ensure your new windows blend seamlessly with your home’s aesthetic.

Budgeting Tips For Your Sash Window Project

Now that you know about the cost and factors that influence them, here are some budgeting tips for sash windows that you must follow:

• Plan ahead: Set a realistic budget early on. Consider the total number of windows you want to replace or repair, the style of the sash window, and any additional features.
• Consider long-term savings: Double glazing and energy-efficient windows can have a higher upfront cost but will save you money on heating bills in the long term. Make sure to factor in potential savings.
• Get multiple quotes: Always obtain quotes from reputable companies to ensure you get a fair price. Look for companies with good reviews and a reputation for quality craftsmanship, which offers transparent pricing and a 10-year guarantee.
• Look for finance options: If your project exceeds your immediate budget, some companies offer finance options to spread the cost over time.
