How do I get a quote from a window installer in Leicester?
Use the "Get Free Quotes" form on this page. Your job details go to FENSA or Certass registered installers covering the LE postcode area, who contact you directly. Leicester has 198 registered window and glazing businesses in this directory, though the installers who quote are not necessarily among them. It is free and there is no obligation.
Should I repair or replace my windows?
Repair makes sense for a failed seal (misted double glazing), a worn handle or hinge, or a damaged lock on an otherwise sound frame — usually a straightforward swap. Replacement is the better value once frames are warped, draughty, rotten (on timber) or past roughly 20 to 25 years old, or when several units across the house have failed. Ask the installer to price both where it's borderline.
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.
How many window and glazing companies are there in Leicestershire?
This directory holds 361 active window and glazing businesses across 31 towns in Leicestershire, all from the Companies House register. Leicester accounts for 198, among the county's busiest. About 30% of Leicestershire's registered window and glazing firms were incorporated in the last three years, so weigh incorporation date and FENSA/Certass registration, not just company age.
