What does this page tell me about Marioconstructionco Ltd?
The registered company name, registered office address, Companies House number and incorporation date, all taken from the public Companies House register. It does not include reviews, prices, staff details, or confirmation that the company is currently trading.
Can I see reviews for Marioconstructionco Ltd?
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.
