What Goes Wrong
The frame opening tells you more than the frame itself, skipping that check is where problems start.
Fitting a new frame over a damp or damaged reveal traps moisture and causes the new window to fail early.
The installer checks the reveal for damp and rot before the new unit is measured in and ordered.
Standard off-the-shelf units rarely fit older Havering properties, leaving gaps that let in draughts and water.
Older homes in the borough are measured individually so the replacement frame fits the actual opening.
Replacement windows without FENSA registration or a Building Regulations certificate can block a property sale.
The installer manages FENSA self-certification so the Part L compliance paperwork is ready when the job is done.
Replacing a whole window when only the sealed unit has failed adds unnecessary cost and disruption.
The written quote sets out both options, sealed unit swap or full-frame replacement, before anything is ordered.
Scope of Work
From a single misted pane to a full run of frames across the property, the scope depends on what the survey finds.
Old frames are removed and replaced with new uPVC units, fitted level and sealed on all faces for draught-free performance.
Rotted or warped timber frames are taken out and replaced with new timber units, sized to the original opening.
Aluminium replacements suit properties where a slimmer sightline or a more contemporary finish is needed.
Where the frame is still sound, a failed double-glazed unit is swapped out without disturbing the surrounding frame.
Non-standard openings in older terraced or semi-detached homes are measured and fitted with made-to-size frames.
Included where Approved Document F requires it.
Taken away as part of the job, not left on site.
All faces sealed and finished after fitting.
Remove, Inspect & Refit
The material choice, uPVC, timber, or aluminium, matters less than getting the opening condition right before the new frame goes in.
Many properties across Havering carry original or early-generation frames that are now warping, letting in draughts, or showing misted sealed units that cannot be fixed without removing the sash. The installer assesses the frame first: if the frame itself is sound, a sealed unit swap may be sufficient. Where the frame has rotted, shifted, or failed at the corners, full removal is the right call, and the quote will explain why.
Once the old frame is out, the opening is checked for damp, rot, and structural condition before the new unit is measured in. Older homes in the borough often need made-to-size frames rather than standard units. The replacement window, uPVC, timber, or aluminium, is fitted, shimmed level and square, and sealed on all faces. Trickle vents are included where required by Approved Document F.
Replacement windows in a dwelling require FENSA registration or a Building Regulations completion certificate to meet Part L thermal performance requirements. The installer handles self-certification, so the paperwork is in order when the job is finished. The written quote lists frame supply, glazing unit, labour, old-frame removal, and certification as separate line items.
Why Choose Us
We connect you with vetted local installers who survey first, quote in writing, and handle compliance, so nothing is left to chance.
A local installer visits the property to record frame condition before a quote is prepared or materials are ordered.
The itemised quote covers glass, frames, labour, old-frame removal, and certification, each listed as a separate cost.
Where a sealed unit swap is enough, the quote says so. Full replacement is only recommended when the frame warrants it.
FENSA self-certification and Part L documentation are arranged by the installer and handed over on completion.
Work is planned to keep time on site short, with old frames removed and the opening closed in a single visit where possible.
