How does First Home Improvements compare to other double glazing companies?

First Home Improvements is company with a good reputation and a great selection of uPVC window styles. However, other companies may be a better fit for you, especially if you’re interested in different frame materials.

Anglian, our top choice of double glazing company in the UK, is similarly priced to First Home Improvements, offering a 10-year guarantee on all parts and labour and a 15-year guarantee on gas-filled windows. Its uPVC windows are rated A to A+ for energy efficiency.

Another benefit of choosing Anglian to supply your new windows is its selection of frame materials, including timber and aluminium. Additionally, many of its window styles (tilt and turn, sliding sash and casement) are SBD-approved for their high security standards.

If you are interested in a more premium brand, consider Everest. It’s one of the oldest and most reputable double glazing providers in the UK, with a host of accreditations, including Secured by Design, Quiet Mark, FENSA, TrustMark, BSI, BFRC, FSC and BSI Kitemark. Windows from Everest’s uPVC Exclusives range come with a 20-year guarantee. What’s more, Everest sells triple-glazed windows for extra energy efficiency.

There are plenty of benefits to uPVC windows. Unlike timber frames, they require very little maintenance and are not as vulnerable to degradation.

First Home Improvement windows come with a solid 12-year guarantee, which is longer than the industry average, and there are generally positive reviews about the company online.

Frequently Asked Questions about First Home Improvements double glazing windows

First Home Improvements services customers in most England counties, including Norfolk, Suffolk, Essex, Cambridgeshire, Lincolnshire, Leicestershire, Northamptonshire, Bedfordshire, Buckinghamshire, Oxfordshire, Berkshire, Hertfordshire, Warwickshire, Kent, East & West Sussex, Surrey, Hampshire and Dorset.

If you are noticing your energy bills increasing, draughts, or condensation between the panes of glass inside your double glazing, it may be worth updating your double glazing.

Although the sealed units can last for around 30 years, they can eventually become faulty. If this falls within your warranty period, contact your installer for replacement windows. Outside this period, consider the benefits you’ve enjoyed from having double glazing when thinking about getting new units.

Triple glazed windows are becoming increasingly popular, and many installers offer this option. Although pricier than double glazing, the addition of an extra spacer and glass panel increase the insulation offered by up to 40%.  Other benefits increase over double glazing, too, including sound insulation and home security.

Misting occurs when the seal on a double glazing unit become faulty, and this can be repaired by a professional, although the issue may return.

A small hole is drilled through the frame and a desiccant agent pumped in. This will absorb the moisture, leaving the space between the glass panes dry. This can be a risky process, and there’s no guarantee that the window won’t be damaged.

Many double glazing providers offer customisation of their uPVC window frames using a range of colours and finishes. This makes is easy to increase the appeal of your home, and give the windows a personal touch.

Woodgrain effects, such as oak, beech and maple, are popular choices, but colours, especially bolder hues are rapidly increasing in popularity. Blues and greens offer wide palettes, with the more subtle tones blending well with period architecture. Braver colour choices, such as burgundies and yellows bring a stylish splash of contemporariness to any exterior.
