FAQs – Cost & Value
Learn about common window and door problems and their solutions.
Are new windows and doors a good investment?
Definitely. Not only do they improve your home’s curb appeal and security, but their energy efficiency can lead to significant savings on your heating bills. They are also a highly desirable feature for potential buyers, adding to your home’s value.
What factors affect the cost of a new window or door?
The main factors are the size, the material (uPVC or Aluminium), the style (e.g., casement vs sash), the colour, the hardware choices, and the glass specification (e.g., triple glazing or acoustic glass).
Why are bifold doors more expensive than patio doors?
Bifold doors have a far more complex design, with multiple moving panels, sophisticated roller systems, and advanced locking mechanisms. This intricate engineering and the high-grade materials required contribute to their higher price point.
Is it cheaper to replace all my windows at once?
Yes, it is usually more cost-effective. Ordering a full house of windows at once can reduce the overall cost per window due to economies of scale in manufacturing and the efficiency of completing the installation in a single project.
Do you offer finance options?
We don’t offer finance.
How much value will a new front door add to my home?
A new front door, especially a high-quality composite door, dramatically improves your home’s kerb appeal. It creates a fantastic first impression and can make a property feel more secure and well-maintained, which is a huge plus for potential buyers.
Is paying a deposit safe with KMJ Windows & Doors Ltd?
Yes, completely. As a reputable Assured-registered company, your deposit is safe. We also provide an insurance-backed guarantee, which gives you an extra layer of security for any money you pay upfront.
Does the price in my quote include VAT?
Yes, all our quotes are fully transparent. The price you are quoted is the price you pay and includes VAT, professional installation by our own expert team, and the disposal of your old frames.
Will new windows really reduce my energy bills?
Yes. Replacing old, inefficient windows with our modern A-rated double glazing can stop a huge amount of heat from escaping your home. This means your heating system works less hard to maintain a comfortable temperature, which can lead to noticeable savings on your bills.
Do different uPVC colours cost more?
Standard White is the most cost-effective option. Coloured and woodgrain foil finishes involve an extra process during manufacturing, so they typically cost a little more than white.
