Why Choose Apex Windows in Hitchin?
Most double glazing companies still send a salesperson to your home before giving you a price. Apex doesn’t.
You get a real, accurate quote online in under 10 seconds. No appointment, no commission-driven rep, no pressure. For homeowners on Hitchin’s Victorian terraces or the post-war semis of the Poets Estate and Walsworth, that matters: over half of North Hertfordshire homes currently fall below EPC Band C, and replacing failing glazing shouldn’t mean sitting through a sales pitch first.
Apex has been trading for over 35 years, based in Luton and serving Hitchin and the wider Hertfordshire area. Every fitter is directly employed. No subcontractors, ever.
All installations come with a 10-year insurance-backed guarantee through InstallSure. Apex is FENSA registered (No. 31157), endorsed by Which? Trusted Traders, and rated 9.83/10 on Checkatrade.

Our Double Glazing Service in Hitchin
Hitchin’s housing spans several eras, from Victorian terraces in and around the town centre to Edwardian semis in Bearton and West Hitchin, post-war houses on the Poets Estate, and 1960s family homes across Walsworth. That variety means window and door choice is rarely one-size-fits-all. Chalk valley winters and easterly winds make heat retention a real consideration in the town’s older stock.

Conservatories in Hitchin
Period properties on the town centre streets and in Bearton suit sliding sash windows or flush sash windows, while casement windows are the standard replacement choice on the Poets Estate and Walsworth semis. For homes close to the railway line on Walsworth Road or Cambridge Road, triple glazing rated A++21 cuts train noise as well as heat loss. Double glazing is A+13 rated.
All windows are priced with VAT and fitting included. Apex also carries out double glazing repairs and replacement sealed units for homeowners whose existing glazing has failed but frames are still sound.
Composite and uPVC front doors suit the full range of Hitchin property types, from Victorian terraces needing a period-sympathetic entrance to post-war semis where security and weatherproofing are the priority. Patio and French doors work well on the larger plots in Purwell and Walsworth.
Multi-point locking and toughened safety glass come as standard on every door. Use the instant online calculator to price yours.
Conservatories add usable space without the cost or disruption of a full extension. Victorian conservatories suit the bay-fronted terraces and Edwardian semis common in Bearton and the older streets off the town centre. Edwardian conservatories work well on the larger detached and semi-detached homes in Purwell and Walsworth, where rear garden plots give space for a full-width build.
Modern glazing keeps them usable year-round. Every installation is covered by the 10-year insurance-backed guarantee through InstallSure. Speak to our team to discuss your options.
What Our Customers Say
Frequently Asked Questions
My windows are misting up between the panes. Do I need a full replacement or just a repair?
Misting between the panes means the sealed unit has failed, not the frame. If the frame is still sound, Apex can replace just the sealed unit for considerably less than a full window. For 1960s properties on the Poets Estate and across Walsworth, this is often the more practical fix. A site visit will confirm which option suits.
Will new double glazing reduce the noise from trains near Walsworth Road and the Poets Estate?
It will, and triple glazing will do more. Streets close to the East Coast Main Line deal with regular intercity and freight traffic. Triple glazing, rated A++21, adds a third pane and a wider air gap that cuts more of the low-frequency noise trains produce. Apex fits triple glazing across its full window range.
I live in a Victorian terrace near Hitchin town centre. Can I replace my windows with uPVC?
In most cases, yes. uPVC doesn’t automatically require planning permission outside the conservation area, and sliding sash or flush sash uPVC windows are designed to suit period properties without compromising their appearance. If your property is listed or sits within the Hitchin Conservation Area, see Q4.
Do I need planning permission to replace windows in Hitchin's conservation area?
It depends on the property. Hitchin’s Conservation Area covers the historic town centre and contains around 300 listed buildings. Window replacements don’t automatically require planning permission, but the council expects materials and style to preserve the character of the area. Listed buildings have stricter controls. Apex can carry out a site visit to assess your property before any work is planned. Confirm requirements with North Hertfordshire Council’s planning team first.
Is triple glazing worth the extra cost in Hitchin?
For many homes here, yes. Hitchin sits in a chalk valley exposed to easterly winds, and older properties lose heat quickly through ageing glazing. Triple glazing, rated A++21, retains significantly more heat than A+13 double glazing and reduces noise from the railway and the A602. The comfort improvement is immediate.
Are you FENSA registered?
Yes. Apex Windows is FENSA registered (No. 31157). This certifies that your installation complies with Building Regulations. Every job includes a 10-year insurance-backed guarantee through InstallSure.
Do I need to wait for a salesperson to visit before I can get a price?
No. Apex provides quotations without a home visit. Use the online calculator to get a fitted price in under 10 seconds, including VAT. If you decide to proceed, we arrange a survey to confirm measurements before manufacturing starts.
