  • Are wooden windows better than uPVC?

    It’s safe to say that if you’re in the market for new windows, uPVC and wood are both fantastic options. 
    If your present windows are made of wood, it may not always be the best option to replace them with wood or uPVC.
  • What are the benefits of engineered timber windows?

    The advantages of this procedure include:
    • Expense.
    • Strength. 
    • Appearance.

    • Friendly to the environment
  • How long do wooden windows last?

  • Are wood windows Bad?

    Vinyl, metal, and fibreglass windows all have reputation for being low-maintenance, but wood has the opposite problem. 
    When it comes to wood windows, it’s true that they are vulnerable to pests if they aren’t properly sealed. 
    You don’t need to reseal windows for years if you give them decent dusting.
  • Why are wooden windows so expensive?

    Because hardwood windows take longer to mature, they are more costly. 
    For the typical house, replacement windows should cost between £8,000 and £20,000.
  • When should you replace wooden windows?

    Visible decaying or peeling paint is warning indication that wooden window should be replaced. 
    Wooden windows, although being treated to withstand the environment, may gradually lose their capacity to resist moisture over time. 
    When paint begins to separate from the wood, this is known as peeling paint.
  • How often should wooden windows be painted?

    Solid colours should last between five and eight years before repainting, whereas wood stains should last between three and five years before repainting.

  • Are Aluminium Windows better than timber?

    Aluminium windows are often less expensive than wooden windows. Better-quality aluminium windows that are more thermally insulated cost about the same as a comparable number of wood windows. Because they don’t need any upkeep, aluminium windows do deteriorate with time. Most wood windows can outlive most aluminium windows if they are properly cared for.
