Common questions about window guarantees
Helpful answers before you decide.
Choosing new windows is easier when you understand the reassurance behind them. These answers explain what homeowners often ask about TWC’s 20 Year Window Guarantee.
1. Why does a longer guarantee matter?
A longer guarantee gives you more confidence that your replacement windows are designed to perform well beyond the short term. It shows that TWC expects its products, materials and installation standards to last. For homeowners, this means added reassurance when making an important investment in comfort, appearance, security and energy efficiency.
2. Does the guarantee show product quality?
Yes, a strong guarantee can be a useful sign of confidence in the product. TWC can offer a 20 Year Window Guarantee because its windows are made with durable materials, reliable components and careful manufacturing standards. This helps reassure customers that their windows are intended for long-term everyday use, not short-term replacement.
3. Can I compare guarantees before choosing windows?
Yes, comparing guarantees is sensible when choosing replacement windows. Look at the length of cover, what is included, the company behind it and the quality of the products being installed. TWC advisors can explain the reassurance available with its window collections, helping you make a more informed and confident decision.
4. Are all TWC window collections covered?
TWC’s window guarantee is designed to support its replacement window range, giving homeowners confidence across different styles and collections. Whether you are considering UPVC or aluminium windows, your advisor can explain what applies to your chosen product before you order. This helps make everything clear from the beginning.
5. Will my windows still need maintenance?
Modern TWC windows are designed to be low maintenance, but simple care can help keep them looking and working at their best. Cleaning frames, checking handles and keeping moving parts free from dirt can all support long-term performance. Your advisor can explain any care guidance relevant to your chosen windows.
6. How do I start my window quote?
Start by speaking with TWC about your home, preferred styles and what you want your new windows to improve. You do not need every detail decided. A TWC advisor can help you compare collections, colours, glazing and finishing touches before preparing a tailored quote for your replacement windows.
