Our Double Glazing Service in Hertford
Hertford housing ranges from dense Victorian terraces near the town centre to mid-century builds on the Pinehurst estate. This architectural split means window replacements must respect strict period aesthetics while delivering modern thermal performance, especially for homes exposed to heavy traffic along the A414 corridor.

Conservatories in Hertford
Period properties dominating the Hertford Conservation Area require historically accurate profiles. Our Liniar flush sash windows and sliding sash windows replicate original timber sightlines while upgrading energy ratings to A+13 or A++21.
For post-war housing, standard casement windows provide excellent thermal upgrades. Apex also fits standard windows and provides double glazing repairs or replacement sealed units for failed older frames.
Replacing a front door on a Hertford Edwardian terrace requires matching the original aesthetic without compromising modern security. We install authentic-looking composite and uPVC front doors, plus patio and French doors for rear access.
Every door features multi-point locking and toughened safety glass. Compare styles and prices instantly using our instant online calculator.
Many older Hertford properties benefit from deep rear plots, making them ideal for traditional conservatories. We design and install Victorian conservatories and square-plan Edwardian conservatories to match your home’s original brickwork and era.
Our directly employed fitters manage the entire build under a 10-year InstallSure guarantee. Speak to our team to discuss your project.
What Our Customers Say
Frequently Asked Questions
Will triple glazing reduce traffic noise from Gascoyne Way (A414)?
Yes, upgrading to triple glazing or specific acoustic glass significantly cuts decibel levels in your home. The extra pane of glass and varying gas cavities disrupt sound waves from heavy traffic far more effectively than standard double glazing. If your property backs onto the A414 or the A10, this upgrade makes a noticeable difference to your daily comfort.
Do I need planning permission for replacement windows in the Hertford Conservation Area?
You likely will, as East Herts District Council uses Article 4 directions to remove standard permitted development rights in these zones. This means even exact like-for-like replacements require approval before installation begins. We supply fully compliant flush sash profiles and can advise you on meeting the local heritage requirements.
My Pinehurst home has older double glazing that is misting up. Do I need whole new windows?
Condensation between the panes means the edge seal has completely failed. While swapping just the glass is sometimes possible, most homeowners choose a full frame replacement when dealing with older first-generation uPVC. Upgrading the entire window ensures you benefit from the superior thermal efficiency and advanced locking systems of modern Liniar profiles, rather than putting new glass into a deteriorating frame.
Can uPVC windows replicate original timber frames for character properties in Hertford?
Modern manufacturing allows uPVC to mimic the exact proportions and aesthetics of traditional wood. Our flush sash and sliding sash options feature mechanical joints and authentic woodgrain finishes that satisfy strict conservation guidelines. You gain the historical look required for Hertford period homes without the constant sanding and repainting timber demands.
What security features are included with your composite front doors?
Every door we fit comes equipped with advanced multi-point locking systems as standard. The core of a composite door is inherently much denser and heavier than traditional timber or older uPVC panels, making it highly resistant to forced entry. We also install toughened safety glass in all glazed sections for complete peace of mind.
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.
