How much does new window installation cost in Essex?

Pricing depends on number of openings, frame material (PVC vs aluminium), glass spec and access. We always price line-by-line on a written quote so the breakdown is transparent — request a free survey for an itemised figure on your specific job.

How long does a full house of windows take to install?

Most 3-bed Essex semis are 2–3 days on site, 4-bed detacheds 3–4 days. We work continuously rather than splitting installs over multiple weekends, so you're not living on a building site.

Will I need scaffolding?

Standard first-floor windows are reached from inside or with a tower. Scaffolding is only needed when first-floor windows sit above a single-storey extension or conservatory roof, or for full-house installs on three-storey townhouses. We flag this at survey.

Do replacement windows need building regs approval?

Yes, but Certass notification handles it without involving the local authority. We register every install within 30 days and you receive the Certass certificate by post — proof of compliance for future house sales.

Can I get coloured frames instead of white?

Yes — woodgrain foils (rosewood, agate grey, anthracite, chartwell green) are popular on PVC. Aluminium is powder-coated to any RAL colour. Coloured frames add 1–2 weeks to lead time and a small premium per opening.

What's the warranty on new windows?

Manufacturer warranty on the frame system is typically 10 years (leading PVC manufacturers) or up to 25 years on aluminium. Sealed glass units carry a 5-year fog-free warranty as standard. Our workmanship guarantee adds 10 years on the install itself.

Will trickle vents be fitted?

Building Regs Part F requires background ventilation on new windows in most habitable rooms. We specify discreet trickle vents in the head section by default — they can be opened or closed manually but must be present to comply.

Do you remove and dispose of the old windows?

Yes — included in every quote. Old frames, glass and any debris go in our van and to a licensed recycling facility. You don't pay for skips and you don't have a pile of old PVC on your driveway after we leave.

Overview

Window Installation done properly across Essex

We install replacement windows across Essex from compact two-bed terraces in Basildon up to full-house refits in Hertford and Brentwood. Most jobs are A-rated PVC casements, slim-sightline aluminium for contemporary frontages, or timber-effect PVC where conservation guidance applies.

A typical full-house install runs 2–4 days on site once frames are manufactured. Single windows fit in a day. Every opening is surveyed in person — no off-the-shelf sizing, no manufacturer's templates lifted off a tape-thrown measure.

What goes wrong

What goes wrong when window installs are rushed

The most common issues we get called to fix on other people's installs are: oversized openings packed out with foam instead of properly sized frames; missing trickle vents triggering Building Regs Part F failures; sealant beads applied over wet brickwork that fail within 18 months; and EPDM tapes omitted entirely, letting wind-driven rain track behind the frame into the cavity.

None of those are product failures — they're survey and install failures. A window system from any reputable manufacturer (any leading aluminium or PVC system) will perform for 25–30 years if it's measured and fitted correctly. The cost of a redo is the original price plus disruption, so getting the first install right matters.

Walk-around with you to test every opening, snag list resolved on the spot, Certass notification within 30 days and a written workmanship guarantee.

Benefits

What you get from a window installation job done right

Lower heating bills

A-rated double glazing typically cuts window-related heat loss by around 70% compared to single glazing — measurable on your next winter bill.

Quieter rooms

4mm/16mm/4mm acoustic-laminated units knock 5–8 decibels off road noise — meaningful on the A12, A127 and A13 corridors.

PAS24 security

Multi-point shoot bolts, internally-beaded sashes and laminated glass options on ground-floor openings as standard, not as an upsell.

Weather-tight detailing

EPDM tapes, properly sized frames and silicone-bedded cills — not foam-only installs that fail at the first horizontal-rain storm.

Clean, period-correct lines

Trickle vents specified discreetly, slim sightlines on bays and casements, and timber-effect woodgrain finishes where the property warrants it.

Certass + 10-year guarantee

Building-regs notification handled by us, plus our own workmanship guarantee on top of the manufacturer's frame and glass warranties.

In Detail

Frame systems, glass specs and detailing — what we install and why

PVC frames: we mainly fit leading PVC systems — fully reinforced, multi-chambered, with steel inserts on larger openings. Standard finish is white internally and externally; foiled woodgrains (rosewood, anthracite, agate grey, chartwell green) are a 1–2 week longer lead time but visually transform a frontage.

Aluminium frames: Smart's Alitherm 70/Heritage and premium aluminium window systems are our go-to systems for slim sightlines and large openings. Powder-coat colour is to RAL specification — anthracite (RAL 7016), jet black, slate grey and pure white are the most-asked finishes in Essex.

Glass spec: 4-16-4 argon-filled units with a warm-edge spacer bar are baseline. Acoustic laminated glass (6.4mm front pane) is standard on roadside elevations. Solar-control glass goes onto south-facing rear extensions where overheating is a real risk.

Bay windows: structural posts where required, lead-rolled flashings on bay roofs, and proper soffit detailing — not just three windows trim-stuck together.
