Inspect First
Find the exact fault, draught, failed seal, or sticking sash, before committing to any repair cost.
What Goes Wrong
A window can look perfectly fine and still let in cold air, moisture, or noise, the difference is in the components you cannot see at a glance.
Misting between panes is often blamed on room humidity, when the real cause is a failed sealed unit that needs replacing.
The inspector examines the glazing unit directly, confirming whether the seal has broken down and the unit needs replacing.
Draughts felt near a window can originate from the frame edge, weatherstripping, or a fixing gap, each requiring a different fix.
Where air infiltration is suspected, a smoke test pinpoints the exact gap location so the right repair is agreed.
A window that sticks or will not close flush is often a hinge or lock alignment issue, not a frame fault, but it is treated as one.
Hinges and locks are tested through a complete open-and-close cycle to identify alignment or wear before any frame work is considered.
Post-installation windows without verified FENSA certification may not meet Building Regulations performance standards, creating a compliance gap.
The inspector confirms FENSA certification and checks that the installation meets Building Regulations performance criteria, producing a written record.

Test Before You Spend
Draughts, condensation, and sticking sashes each point to a different component, the inspection identifies which one.
Havering’s mix of older terraced homes and newer builds means window age and specification vary widely across the borough. A quality inspection covers five symptom areas: draughts, condensation between panes, sticking or misaligned sashes, water ingress around the frame, and post-installation sign-off where paperwork is unclear. Each symptom is traced to a specific component, weatherstripping, sealed unit, hinge, frame seal, or fixing, rather than treated as a reason to replace the whole window.
The inspector works through a structured checklist: visual check of the uPVC, timber, or aluminium frame for cracks and movement; sealed unit check for misting or failed seal; weatherstripping condition along the full sash perimeter; hinge and lock operation through a full open-and-close cycle; and a draught check at the frame edges. Where air infiltration is suspected, a smoke test confirms the location of the gap.
Rental properties in Havering are subject to landlord obligations around draught-proofing and habitable conditions, and an inspection report provides a clear record of window condition. For post-installation checks, the inspector verifies FENSA certification and confirms that the installation meets Building Regulations performance standards. The written report sets out each finding and, where faults exist, the repair options available.
