Double glazing installation in Enfield

We supply and install A-rated double glazed windows and doors across Enfield. All glazing units use argon gas filling, low-emissivity glass, and warm-edge spacer bars as standard, achieving whole-window U-values that comply with and exceed the requirements of Approved Document L of the Building Regulations.

Whether you are replacing original single-glazed windows in a period property in Bush Hill Park or Palmers Green, upgrading draughty existing double glazing in a 1980s or 1990s property, or glazing a new rear extension across Edmonton or Grange Park, we supply the right glazing specification for the property and the budget.

Triple glazing is available as an upgrade on all window and door types. It improves thermal performance further and provides additional noise reduction, which is worth considering for properties on or near the A10, the A1010, or close to railway lines at Enfield Chase or Gordon Hill. For most standard Enfield residential properties, modern A-rated double glazing with low-e glass and argon gas is the appropriate and most cost-effective specification.

Double glazing repairs in Enfield

Misted or steamed-up windows indicate a failed sealed unit where the airtight seal has broken down and moisture has entered the gap between the two panes. This is the most common double glazing problem in Enfield properties where original installations from the 1990s and early 2000s are reaching the end of their effective life.

In most cases the sealed unit can be replaced within the existing frame without touching the surrounding reveal, the hardware, or the frame itself. This restores clarity and thermal performance at a fraction of the cost of full window replacement and is typically completed in a single visit.

We also repair and replace handles, friction hinges, and multipoint locking mechanisms across all uPVC and aluminium window types. If the frame itself is damaged or structurally compromised we will tell you honestly at the survey stage rather than recommending repair when replacement is the appropriate solution.

Single glazing vs double glazing vs triple glazing

Single glazing has a U-value of around 5.0 W/m²K. Modern double glazing achieves 1.0 to 1.4 W/m²K. Triple glazing achieves around 0.8 W/m²K. The jump from single to double glazing is substantial and immediately noticeable in comfort, noise reduction, and condensation.

The improvement from double to triple is real but smaller, and the additional cost is only justified in specific situations such as high-noise locations or particularly exposed properties.

All replacement windows must meet the minimum thermal performance requirements of Approved Document L. Our double glazed products achieve an A Window Energy Rating as standard, which exceeds the minimum requirement.

What double glazing costs in Enfield

New double glazed window, supply and install, from £500 to £1,200 depending on style and size. Sealed unit replacement in an existing frame, £150 to £350 per unit. Handle, hinge, and lock repairs, £60 to £180 per window. Triple glazing adds approximately 20 to 35 percent to the window cost.

We carry out free surveys across EN1, EN2, and EN3 and can usually arrange a visit within a few days of your enquiry. All quotes are provided without obligation.

Frequently asked questions

The airtight seal around the perimeter of the sealed unit has failed, allowing moisture to enter the gap between the two panes. This is called a blown unit. The sealed unit can be replaced within the existing frame in most cases, restoring the window without full replacement.

For most standard residential properties, A-rated double glazing is sufficient. Triple glazing is worth the additional cost for properties on busy roads, near railway lines, or with specific high-performance thermal requirements. For noise reduction specifically, acoustic glass within a double glazed unit is often a more cost-effective option than triple glazing.

Sealed units typically last 20 to 25 years before the seal begins to degrade. uPVC frames last 25 to 35 years. Aluminium frames last 35 to 40 years or more. Many Enfield properties have frames in good condition but units that need replacing, making sealed unit replacement the right solution rather than full window replacement.

In most cases no, replacing like-for-like windows falls under permitted development rights. If your property is in a conservation area such as the Enfield Town conservation area, there may be planning considerations. If your property is listed, listed building consent is required. We are happy to advise on your specific situation.

Full replacement may not be permitted. Secondary glazing, an additional internal panel fitted inside the existing window, is the appropriate alternative in these situations and significantly improves thermal and acoustic performance without altering the external appearance. We cover secondary glazing in more detail on our sliding sash windows page.

We can usually arrange a survey within a few days across EN1, EN2, and EN3. Sealed unit replacements are typically completed within one to two weeks of the survey depending on the unit specification and current lead times.
