Know Before You Spend
Find out exactly what is wrong and whether your windows meet building regulations before spending anything.
Common Inspection Pitfalls
A rushed or incomplete check can lead to unnecessary replacement costs or missed compliance gaps.
Misting between panes is often quoted as a full window replacement when only the sealed glazing unit has failed.
The inspection separates frame condition from glazing unit failure, so only the faulty component is addressed.
Replacement windows fitted without a FENSA certificate or local authority completion certificate breach building regulations.
The inspection checks whether a valid FENSA certificate or Havering building control completion certificate exists for the windows fitted.
Trickle vents are required under Approved Document F; their absence is frequently missed when only visible damage is checked.
The inspection records trickle vent presence and weatherseal continuity alongside frame and glazing condition.
Assessments based on photographs alone cannot detect draught paths, hinge wear, or lock failure that only show under handling.
The property gets an on-site visit: each window is opened, closed, and tested before findings are recorded in a written report.
What We Check
Every inspection looks at the full window assembly, not just the most visible symptom.
uPVC, timber, and aluminium frames are examined for warping, rot, cracking, and weatherseal continuity around the perimeter.
Each glazing unit is checked for misting, seal failure, and whether the glass specification meets Approved Document L thermal requirements.
Hinges, handles, and locks are tested through their full range of movement to identify sticking, misalignment, or worn components.
Trickle vent presence and condition are recorded against Approved Document F requirements for replacement window installations.
The inspection confirms whether a FENSA certificate or local authority completion certificate exists and matches the windows currently fitted.
