Kent-based since 1998 · FENSA registered · 10-year workmanship guarantee
Serving Kent, DA, BR, ME, TN…
Kent is our home county. Our workshop and office are in Greenhithe (DA9), and the majority of our installs each week are within a 30-mile radius across Dartford, Sevenoaks, Tunbridge Wells, Maidstone, Medway, Ashford and Canterbury. That proximity means faster survey slots, quicker snagging visits and no travel-surcharge nonsense on the quote.
Because we live and work here, our surveyors already know the housing stock: 1930s semis in Bexleyheath, weatherboarded cottages in the Weald, coastal properties exposed to salt-laden winds, and new-build estates around Ebbsfleet and Ashford. Specification is tuned accordingly, coastal-grade hardware where relevant, thermally broken aluminium for exposed elevations, and heritage profiles for conservation villages.
Our typical Kent projects include full-house window replacement, warm-roof conversions on tired conservatories, composite front doors, and aluminium bi-folds on kitchen extensions. Every install is FENSA registered, backed by our 10-year workmanship guarantee, and covered by £5m Public / £10m Employers' Liability insurance.

Common issues in Kent properties
Kent's housing mix spans Victorian and Edwardian terraces in the north-west towns, inter-war semis across Dartford and Bexley, Kentish weatherboard and tile-hung cottages in the Weald, coastal bungalows and interwar seaside stock along the estuary and channel coast, and dense modern estates around Ebbsfleet, Ashford and Maidstone. Openings vary wildly, so we measure every one on site.
Coastal exposure
Salt-laden winds along the estuary and channel coast attack cheap hardware and unprotected steelwork. We specify marine-grade fixings and powder-coated aluminium where exposure warrants it.
Ageing conservatories
Many Kent conservatories fitted in the late 1990s and early 2000s are now too hot in summer, freezing in winter and leaking around the box gutter. Warm-roof conversions solve all three.
Chalky ground and settlement
North Kent's chalk geology can cause differential movement on older properties. We survey base condition before quoting any conservatory or extension glazing.
Rural noise and wildlife access
Rural Kent properties often need better acoustic performance against agricultural machinery and improved sealing to keep out insects and wildlife around openings.
