Is Dean Flannery Carpentry & Building Services Ltd FENSA or Certass registered?
This directory does not confirm registration. Window and door installers self-certify their work against Building Regulations through a Competent Person Scheme — mainly FENSA or Certass — so check the company name or postcode (ME10 5BH) directly on the FENSA or Certass website before booking, and ask to see the certificate number.
Can I see reviews for Dean Flannery Carpentry & Building Services 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.
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.
Does a listing here mean Dean Flannery Carpentry & Building Services Ltd 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.
How many window and glazing companies are there in Kent?
This directory holds 478 active window and glazing businesses across 41 towns in Kent, all from the Companies House register. Sittingbourne accounts for 23. About 26% of Kent'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.
