How much does window replacement cost in York?
A single uPVC window in York typically runs £300 to £600 supplied and fitted; a full house of 8 to 10 windows is often £3,000 to £8,000 depending on style (casement, bay, sash-look) and glazing spec. Get two or three written, itemised quotes before agreeing to work.
Do uPVC windows need any maintenance?
Not much, but not none. Wipe the frames a few times a year, lubricate hinges and locks annually, and keep the drainage channels along the bottom of the frame clear so water can't pool and find its way inside. There is no statutory annual service like a boiler needs.
Can I see reviews for Coulsy Limited?
Not here. This is a register-based directory, not a review site. Look at independent review platforms, ask the installer for recent local references, and confirm FENSA or Certass registration before any work starts.
What is a FENSA or Certass certificate and why does it matter?
It's proof the window or door installation meets Building Regulations (thermal performance, safety glazing, ventilation) without a separate council building control sign-off. Without one, selling the property can mean paying for retrospective building control inspection or indemnity insurance, so keep the certificate with your house documents.
Does a listing here mean Coulsy Limited is recommended?
No. Companies appear in this directory because they are on the Companies House register under a window/joinery installation trade code. A listing is not vetting, endorsement, or a guarantee that the company is trading or FENSA/Certass registered.
