  • Can I repair double glazing myself?

    In theory, you can attempt some basic window maintenance yourself – such as oiling hinges or replacing a draft excluder. But for blown panes, broken locks, or cracked glass, DIY is not recommended.

    It’s generally best to leave double glazing repair to the professionals. Attempting DIY repair could invalidate the double glazing warranty and damage the window or door further.

    Most homeowners choose a trained glazier for jobs like replacing a unit or repairing a blown window. You’ll also get better-quality materials and (in most cases) a warranty for peace of mind.

    If you have issues with your double glazing, discuss the details with experienced double glazing repairpeople working in London.

    Benefits of hiring a professional

    Here are some of the reasons why it pays to hire a repairperson to fix your double glazing:

    • A double glazing repairperson will have the expertise to identify and fix a wide range of door and window issues
    • Reputable double glazing repairpeople use high-quality materials and techniques to ensure a durable and long-lasting repair
    • Double glazing repairpeople are trained to work safely, especially when dealing with glass and heights
    • A properly repaired double glazing unit can significantly improve your home's energy efficiency and reduce your energy bills
    • A well-maintained double glazing system can enhance your home’s security and deter potential intruders
    • Professional double glazing services should have insurance coverage that protects you from potential liability issues
    • Many double glazing repair companies operating in London offer warranties on their work to give you peace of mind
    • A professional will understand local building codes and regulations and will carry out compliant work

    By hiring a double glazing repair service in London, you can enjoy a safer, more energy-efficient, and more valuable home.

  • How long does it take to repair double glazed windows?

    The time it takes to repair double glazing depends on the problem. Some repairs can be done in under an hour, while other major issues (such as blown double glazing repairs or full replacements) might take days.

    As a guide, here are some estimated timings for common double glazing repair jobs in the UK – actual times may vary:

    • Replacing a broken window handle – 1-2 hours
    • Replacing a broken window hinge – 2-3 hours
    • Replacing a broken window lock – 3-8 hours
    • Replacing a broken pane of glass – 3-8 hours, or split over 2 days if custom glass is needed
    • Repairing a broken seal – 3-8 hours
    • Replacing a faulty double glazing unit – 1-3 days, depending on supplier lead time

    For accurate timings, discuss details with a double glazing repairperson working in London.

    In most cases, a tradesperson will need to assess the window first and measure up before ordering the right part. This might mean a short delay before they return to complete the work. Some window repairpeople are able to offer an express service if the part is standard size and in stock.

    If your issue is urgent (for example, a cracked or broken pane), mention this when you request a quote. Many Checkatrade glaziers offer emergency callouts in London.

  • Can I claim tax relief on double glazing repair costs?

    The tax implications of double glazing repair costs will depend on whether you’re dealing with your home or a business property.

    For your home:

    • Unfortunately, you can’t claim tax relief on the cost of double glazing repair on your home
    • You may be eligible for tax relief if you're making energy-efficient improvements to your home, such as installing new, energy-efficient windows

    For a business property:

    • Double glazing repair and maintenance costs are typically considered to be a deductible business expense
    • If the repair involves a substantial improvement to the property, you may be able to claim capital allowances, which can reduce your taxable profits over multiple years

    To understand the tax implications of double glazing repair and to claim any deductions, consult with a qualified tax advisor or accountant.

  • How often should I have my double glazing checked?

    Ideally, it’s recommended that you have your double glazing checked annually. An annual inspection should cover the following key areas:

    • Checking seals for any signs of damage or deterioration
    • Inspecting the glass for cracks, scratches, or fogging
    • Examining the frames for any signs of rot, warping, or damage
    • Testing all locks, handles, and hinges to ensure they’re working properly
    • Checking drainage channels to ensure they’re clear and free of debris

    By addressing any issues identified during the inspection, you can help maintain the energy efficiency, security, and overall performance of your double glazing.

    In addition to regular inspections, check out our guide on how to maintain double glazing to help extend its lifespan.

  • What are the signs that I need double glazing repairs?

    If your double-glazed windows or doors are showing any of the following signs, it could indicate you need double glazing repair, including:

    • Condensation or misting inside the panes: This often means the seal is broken and the insulating gas has escaped, which affects the window’s performance. It’s a classic symptom of blown double glazing.
    • Drafts or uneven temperatures indoors: If you’re noticing cold spots or rising heating bills, it could be due to damaged seals or warped frames.
    • Cracked, chipped or broken glass: Even small chips can compromise safety and insulation. If the outer pane is damaged, it needs urgent attention.
    • Sticking handles or stiff hinges: If the mechanism is worn, misaligned, or damaged, it can make windows hard to open and close securely.
    • Excess outside noise: Failing seals or thin panes can lead to reduced sound insulation, which can be especially frustrating in busy areas.

    If you notice any of the signs above, it’s time to contact an experienced double glazing repair service working in London. Many small fixes can be done quickly and affordably - and may prevent the need for a full replacement down the line.

  • How much does window replacement cost?

    The exact cost will depend on several factors, including the size, style, material, and glazing type.

    As a rough guide, here are some average costs for the supply and installation of a new window in the UK:

    • Casement windows – £500
    • Sash windows – £1,000
    • Sliding windows – £700
    • Tilt and turn windows – £700
    • Bay windows – £2,500
    • Bow windows – £3,000

    Factors affecting the cost of window replacement

    To get a more accurate price for replacing your window(s), you’ll want to consider the following factors:

    • Size of the window(s) – Larger windows generally cost more

    • Type of glazing – Double or triple glazing is more expensive than single glazing

    • Window style – Bay windows and other complex styles cost more than standard windows

    • Quality and type of materials – Higher-quality windows often come with a higher price tag and different materials, like uPVC and timber, have varying costs

    • Number of windows – The more windows you need, the higher the overall cost

    • Location – Labour costs often vary depending on where you live, e.g. London and the South East are typically more expensive than other parts of the country

  • Is double glazing repair covered by home insurance?

    Whether double glazing repair is covered by your home insurance depends entirely on the specific terms of your policy.

    Therefore, it’s essential to check your policy documents carefully to understand the specific terms and conditions.

    Typically, accidental damage to your double glazing, such as a broken pane due to a storm or accidental impact, is often covered by home insurance.

    However, general wear and tear or negligence is not usually covered.

    And, remember, your home insurance policy is likely to have an excess amount, which you'll need to pay before the insurer covers the rest.
