Blown Windows

What Are Blown Windows?

Blown windows occur when the seal between the panes of double-glazed windows fails. This seal failure allows moisture to enter, causing condensation and fogging between the glass panes. Identifying blown windows is relatively straightforward. If you notice persistent fogging or condensation that cannot be wiped away from the inside or outside, you likely have a blown window.

The causes of seal failure can vary. It might be due to poor installation, the natural degradation of materials over time, or extreme weather conditions that stress the seals. A damaged window not only reduces the thermal insulation of your windows but may also lead to higher energy expenses and a less comfortable living environment. Timely attention to blown windows is crucial for preserving the overall energy efficiency of your house and mitigating further harm.

The Impact on Your Home

Blown windows can significantly affect your energy bills and home insulation. When the seal is compromised, it allows for air exchange between the inside and outside of your home. Greater energy use happens when your heating or cooling system has to work harder to keep the temperature inside comfortable, which causes energy costs to go up.

Diy Vs. Professional Repair

DIY vs. Professional Repair

Pros of DIY Window Repair

  1. Cost-Effective: One of the primary benefits of do-it-yourself window repair is the reduction in expenses. The cost of professional maintenance may be high, mainly when dealing with several windows that need to be repaired or replaced. By opting to do it yourself, you only need to invest in the materials and tools, which are often significantly cheaper than hiring a professional.
  2. Convenience: With a DIY kit, you can fix the problem at your own pace and convenience. There’s no need to schedule an appointment or wait for a professional to come to your home. You have the flexibility to work on the repair whenever it fits into your schedule, whether it’s during the weekend or in the evening after work.
  3. Satisfaction: There’s a certain sense of accomplishment that comes with completing a DIY project. When you repair your windows, you gain hands-on experience and practical skills. Plus, you’ll have the satisfaction of knowing you tackled the problem yourself, which can boost your confidence for future home improvement projects.

Cons of DIY Window Repair

  1. Skill Level: Only some people are handy with tools, and some may find the process challenging. It often requires a certain level of expertise and understanding of how windows are constructed and function.
  2. Time-Consuming: DIY repairs can be incredibly time-consuming, especially if you’re doing it for the first time. You may need to spend hours researching, gathering materials, and learning techniques before even starting the repair.
  3. Risk of Error: There’s always the risk of making mistakes, which could lead to additional costs if you need to call in a professional to fix your errors. Errors can range from minor issues, like improper sealing, to significant problems, like damaging the window frame or glass.

Cost Comparison

When evaluating the prices associated with do-it-yourself (DIY) window repair vs professional repair services in the United Kingdom (UK), it is crucial to take into account both immediate and long-term costs. Here’s a detailed breakdown:

DIY Window Repair Costs:

  • Materials and Tools: The initial cost of a DIY repair kit varies depending on its quality and complexity. On average, a basic repair kit might cost between £20 and £50. Kits typically include the necessary sealant, cleaning brushes, and instructional materials.
  • Additional Tools: If you don’t already have tools like a caulking gun, glass cleaner, or protective gloves, you should purchase them separately. These extra tools can add another £10 to £30 to your expenses.
  • Time Investment: While this isn’t a direct financial cost, it’s worth noting that DIY repairs require a significant time commitment. Be prepared to spend several hours on research, preparation, and the actual repair process.

Professional Window Repair Costs:

  • Service Charges: Hiring a professional to repair blown windows usually involves a service call fee, which can range from £50 to £100. This fee covers the professional’s time and travel expenses.
  • Repair Costs: The precise cost of repair is contingent upon the magnitude of the damage and the dimensions of the window. On average, professional maintenance can range from £100 to £300 per window. If multiple windows need repair, some companies may offer discounted rates for bulk services.
  • Guarantee: One advantage of professional services is the guarantee they often provide. If the repair fails within a specified period, the company usually offers a free follow-up repair.
