WINDOW POINTERS
Worth knowing before you plan the work, set a budget and hire a Window Specialist.
REGULATIONS & SAFETY
You should receive a FENSA or CERTASS certificate within a few weeks of completion — chase it if it hasn't arrived, since some installers register the job but delay sending the physical certificate. Keep it with your house paperwork; you'll need it when you sell.
USEFUL TO KNOW
Modern replacement windows and doors use multi-point locking as standard, and some are tested to PAS 24 security standards — worth asking about specifically if security is a priority, since not every installer fits PAS 24-rated hardware by default even on similar-looking frames.
WORTH KNOWING
Cost depends on frame material, glazing type (double vs triple), the number and size of openings, and whether it's a like-for-like replacement or involves altering the opening size. Bay windows and bifold doors cost more than standard casement windows of the same total area.
GOOD TO KNOW
In a leasehold flat, window replacement sometimes needs freeholder or management company permission, particularly if it affects the building's external appearance — check your lease before booking work, not after ordering.
SAFETY & COMPLIANCE
Do I need a certificate for a single window replacement? Yes, the same Part L rules apply whether it's one window or the whole house. Can I fit my own windows? Technically yes, but you'd then need a separate council building control inspection, which most installers' FENSA/CERTASS registration avoids automatically.
GOOD TO KNOW
A garden room used year-round needs the same Part L-compliant glazing as house windows, not just any glazed unit — worth checking this is specified if you're having a garden office or similar built, since it affects both comfort and any future certification needed.
USEFUL TO KNOW
Condensation on the inside of the glass is a ventilation/humidity issue in the room, not a window fault. Condensation between the panes means the sealed unit has failed. Condensation on the outside (on a cold morning) is actually a sign of a well-insulated window, not a problem.
USEFUL TO KNOW
New-build glazing has to meet Part L from the outset, same as replacement windows, and is usually specified alongside the wider build rather than as an afterthought — window position and size affects room lighting and ventilation calculations the rest of the design depends on.
ABOUT THIS AREA
St Winnow is a civil parish in Cornwall with a population recorded at 328 in the 2011 census. The parish church town sits on the east bank of the River Fowey, south of Lostwithiel, and part of the village of Lerryn and the Chapel of St Nectan lie within the parish; the Redlake Meadows & Hoggs Moor SSSI is also in the parish. St Winnow is administered by Cornwall Council and is in the PL22 postcode district. For trades searches, PL22 helps identify local contractors serving rural mid-Cornwall. Practical implications: small-parish scale means limited local contractor pools, so allow time when sourcing specialists; rural riverside locations often require attention to flood risk and moisture management in repairs; and older ecclesiastical and vernacular buildings common in such parishes typically need trades experienced in traditional stonework, timber repairs and sympathetic conservation approaches—check Cornwall Council for any permissions needed before major works.
Window work in St Winnow’s parish often involves older stone cottages and ecclesiastical buildings where traditional appearance matters, so specialists experienced with timber sash repair and sympathetic replacements are valuable. Conservation sensitivities in PL22 mean that uPVC or aluminium may not always be acceptable for visible elevations; installers should be prepared to discuss material choices that respect the building’s character.
FENSA or CERTASS registration allows installers to self-certify compliance with Building Regulations for replacement windows, but where a building is listed or within a conservation area you may need to consult Cornwall Council before replacing frames. Homeowners should ask for evidence of experience with timber windows and examples of sympathetic replacements, plus FENSA/CERTASS certificates for non-listing work. Also confirm whether the installer will advise or assist with any council permissions required for historic façades.
