WINDOW ADVICE
Helpful information to plan your job, understand costs and choose the right Window Specialist.
USEFUL TO KNOW
Window specialists handle full window replacement, double glazing unit repairs (a fogged unit usually means a failed seal, not the whole frame), door replacement, conservatories, and draught-proofing. Composite and bifold doors are increasingly common alongside standard uPVC window replacement.
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.
USEFUL TO KNOW
Fitting itself is typically one day per 4-6 windows once the made-to-measure units arrive (the survey-to-fitting lead time, 2-6 weeks, is usually the longer wait). A full house re-glaze commonly takes 1-3 days of on-site work.
PROFESSIONAL STANDARDS
Frame guarantees commonly run 10 years, glazing unit guarantees are often shorter — ask specifically, since a failed seal (misting between panes) is a glazing unit issue, not a frame issue, and needs to be covered by the right guarantee. Installation workmanship guarantees are usually separate again.
WORTH KNOWING
Listed building consent is usually required to replace windows in a listed property, and uPVC replacements are often refused — timber matching the original profile is typically required instead. Conservation areas have similar restrictions even where the property isn't individually listed. Check with your local planning authority before ordering anything.
REGULATIONS & SAFETY
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.
COMMON QUESTIONS
"Misted double glazing means the whole window needs replacing" — usually just the glazing unit, not the frame. "Triple glazing always pays for itself quickly" — the payback period varies a lot by property and current window condition. "uPVC never needs any maintenance" — hinges and seals still benefit from occasional attention.
GOOD TO KNOW
Standard double glazing reduces noise somewhat, but for a genuinely noisy location (busy road, flight path), acoustic glazing with a wider gap between panes or laminated glass makes a bigger difference than upgrading to triple glazing for thermal reasons alone.
ABOUT THIS AREA
A soaring white-limestone spire is the visual anchor of Market Harborough: St Dionysius closes views along the High Street and rises directly from the pavement at the centre of the old market space. The Leicestershire market town, in LE16, began around a late-twelfth-century crossing of the River Welland. Its unusual centre grew as booths became permanent buildings, leaving a dense pattern of streets, yards and narrow burgage plots behind the main frontages. Much of upper High Street reads as Georgian or Regency, including substantial former town houses, but appearances can deceive; the council notes that later facades sometimes conceal seventeenth-century or earlier structures. Nineteenth-century housing extends along entry roads and near the river, while the timber-framed Grammar School of 1614 is a conspicuous survivor beside the church. This layered fabric makes careful diagnosis important before alterations, particularly where old timber, masonry and later additions meet. Practical access also varies sharply. Upper High Street is broad, whereas Church Street, covered passages and deep yards give vans and material deliveries much less freedom. A contractor working behind a frontage may therefore need to agree where to unload rather than assuming the property can be reached directly from the street.
Window work in Market Harborough is shaped by a high concentration of historic frontages where Georgian and Regency facades conceal older structures; this often means replacements must match period proportions and detailing. In conservation-sensitive areas, timber sash replicas or slim-profile frames are usually preferred, and installers registered with FENSA or CERTASS can self-certify compliance with Building Regulations.
Where later facades cover earlier fabric, careful site surveys are needed to ensure new frames fit within existing reveals without damaging historic plaster or joinery. Secondary glazing is frequently recommended as a less invasive way to improve thermal performance while preserving external appearance. When sourcing installers, ask for sash-window experience, registration evidence, and samples or photos of previous conservation-area work.
