WINDOW BASICS
Advice to help you get organised, understand what things cost and find a reliable Window Specialist.
PRICING & QUOTES
Frame and glazing unit costs are often the largest share of a window quote, but fitting labour, old window removal/disposal and making good around the reveal add up too. If a quote looks cheap, check it specifies the same glazing spec as competing quotes, not a lower-grade unit.
RULES & STANDARDS
FENSA and CERTASS are the two government-authorised Competent Person Schemes for window and door replacement in England and Wales. An installer registered with either can self-certify that new windows meet Building Regulations Part L (energy efficiency) without a separate council inspection, and you'll get a certificate proving it — needed if you sell the property.
USEFUL TO KNOW
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.
USEFUL TO KNOW
French doors suit a more traditional look and a narrower opening than bifold or sliding doors, but both leaves typically need to open for full access, unlike sliding or bifold options. The right choice often comes down to the room layout and how the space is actually used day to day.
SAFETY & COMPLIANCE
Part L sets minimum energy efficiency standards for replacement windows and doors — a maximum U-value the glazing must meet. A FENSA or CERTASS registered installer certifies this automatically as part of the job; an unregistered installer means arranging a separate council building control inspection and paying its fee yourself.
GOOD TO KNOW
A misted glazing unit can sometimes be replaced on its own within the existing frame, which is cheaper and faster than a full window replacement — worth asking specifically if the frame itself is otherwise in good condition, rather than assuming the whole window needs replacing.
WORTH KNOWING
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.
RULES & STANDARDS
A proper quote should state frame material and colour, glazing spec, whether old windows/frames are removed and disposed of, the FENSA/CERTASS certificate, and the guarantee length on both frames and glazing units, which can differ.
LOCAL GUIDE
Conwy is a walled market town and the administrative centre of Conwy County Borough in north Wales, with the town and castle on the west bank of the River Conwy opposite Deganwy. Historically part of Gwynedd and earlier Caernarfonshire, the wider community (including Deganwy and Llandudno Junction) had a population of 14,753 at the 2011 census, while the west‑bank ward recorded 4,065. The Conwy County Borough resident population was estimated at about 116,200 in ONS figures. Conwy uses the LL32 postcode district for addresses within the area. For trades and building work, the town’s medieval walls, conservation areas and listed buildings mean contractors experienced in historic fabric and working within strict planning controls are often required; search and filter by LL32 to find local specialists, and expect specific conservation and listed‑building consent processes to be administered by Conwy County Borough Council.
Window work in Conwy’s LL32 postcode often intersects with conservation and listed‑building controls, so installers must be capable of proposing sympathetic replacements that respect original proportions and materials. Timber sash windows are common in historic streets and may require specialist repair rather than wholesale replacement; where new windows are needed a timber‑style solution or approved secondary glazing can preserve appearance while improving thermal performance.
FENSA or CERTASS registration lets installers self‑certify compliance with Building Regulations, but in conservation areas or for listed properties additional consents from Conwy County Borough Council can still be required. A good installer for Conwy will show examples of past work in conservation settings and offer options that match traditional detailing. When hiring a window specialist request FENSA/CERTASS documentation, references for LL32 historic projects, and a plan for any conservation‑area approvals needed. For sash repairs, ensure the fitter can address draught‑proofing and sash‑cord replacement without compromising the original fabric.
