Period bay, 1930s semi, townhouse, apartment or contemporary extension — the house comes before a default product.
About ClearCrest
A more considered way to improve a home.
ClearCrest Windows is built around thoughtful specification, careful surveying, clean installation and a better handover for homeowners across London and the Home Counties.
London & Home CountiesBeautiful windows, doors and living spaces for characterful homes.
Our point of view
A window is part product, part architecture and part installation.
That is why we do not treat an opening as a line item alone. The proportions, material, glass, ventilation, security, access and surrounding finish all influence the result.
Our job is to make those decisions understandable before manufacture, then carry the agreed scope through survey, installation and aftercare.
What we value
Confidence should come from the process.
Four principles shape the way ClearCrest presents, surveys and delivers residential work.
Specify visibly
Important choices belong in writing, not buried in a sales conversation.
Measure before manufacture
Final sizes and installation details are survey decisions, not assumptions.
Stay accountable
Our written workmanship guarantee and aftercare route continue after the installation day.
The ClearCrest Standard
From first brief to final handover.
We have structured the customer journey around the points where home-improvement projects most often become unclear: scope, measurements, substitutions, finishing and aftercare.
- Brief & optionsUnderstand the home, priorities and broad product direction.
- Measured surveyConfirm dimensions, access and installation details.
- Written specificationRecord material, colour, glass, hardware and finishing.
- Handover & guaranteeCare information and applicable warranty documents stay with the customer.
Good specification should make the finished result feel intentional.
