Frequently Asked Questions

1. What are the benefits of uPVC windows compared to aluminium?

uPVC windows offer excellent thermal insulation, require minimal maintenance (no painting needed), and are generally more affordable than aluminium. While aluminium windows provide a sleeker profile, uPVC remains the most popular choice for energy-efficient windows in Havant and Portsmouth due to its durability and cost-effectiveness. All our uPVC windows come with high-security features and a 10-year guarantee.

How much does a new conservatory cost in Hampshire?

Conservatory costs vary depending on size, style, and materials. A basic uPVC conservatory in Waterlooville or Fareham might start from £10,000, while larger orangeries with premium features can cost £25,000+. We offer free, no-obligation quotes and can advise on the most cost-effective solutions for your needs. Remember, a quality conservatory adds value to your home and can be more affordable than traditional extensions.

Are composite doors more secure than uPVC doors?

Yes, composite doors are generally more secure than standard uPVC doors. They combine materials like wood, insulating foam, and GRP (glass-reinforced plastic) to create an extremely strong barrier. Our composite doors in Portsmouth and Havant feature multi-point locking systems, reinforced frames, and high-security cylinders that meet police-approved standards. They also offer better insulation and come in more design options to enhance your home’s curb appeal.

What's the difference between double and triple glazing for windows?

Double glazing has two glass panes with an insulating gas layer, while triple glazing adds a third pane for even better thermal and noise insulation. Triple glazing is ideal for homes near busy roads in Emsworth or Hayling Island, or for maximum energy savings. However, double glazing usually provides sufficient insulation for most Waterlooville homes at a more affordable price. We can advise which option best suits your property during our free consultation.

How long does it take to install new windows in my home?

Most standard window installations in Hampshire homes are completed within 1-2 days. A typical 3-bedroom house with 6-7 windows usually takes our team just one day. We work efficiently to minimize disruption, protecting your home and cleaning up thoroughly afterwards. For larger projects or conservatories, timelines vary – we’ll provide a clear schedule during your quote. Our customers often remark how quickly and neatly we complete installations.

What are the advantages of bi-fold doors over sliding patio doors?

Bi-fold doors create a wide, seamless opening by folding back in sections, offering better access to gardens than sliding doors. They provide more natural light when closed and create a modern, stylish look. Our bi-fold doors in Portsmouth and Waterlooville are available in uPVC or thermally-broken aluminium, with multiple configuration options. While generally more expensive than sliding doors, many homeowners find the aesthetic and functional benefits worth the investment.

Why should I replace my fascias and soffits?

Old or damaged fascias and soffits can lead to damp problems, insect infestations, and structural damage. Our uPVC roofline systems in Havant and surrounding areas are durable, maintenance-free, and protect your home from weather damage. They also improve aesthetics with clean lines and various color options. Replacement typically takes just 1-2 days and prevents costly repairs from water ingress. We’ll inspect your current roofline during our free assessment and advise if replacement is needed.

Are your home extensions faster than traditional building methods?

Yes, our hup! home extensions are completed significantly faster than traditional builds. Using pre-manufactured components assembled offsite, we can typically complete extensions 5 times faster with minimal disruption to your home. This method avoids weather delays common in Hampshire’s variable climate and reduces mess in your garden. From design to completion, our streamlined process ensures your extension is delivered on time and on budget, with the same quality as traditional builds.

What does FENSA registration mean for window installations?

As FENSA-registered installers, we can self-certify that our window and door installations comply with building regulations in Portsmouth and Hampshire. This means you won’t need separate local authority approval, saving time and hassle. FENSA also provides an independent complaints resolution process, though our 10-year guarantee and Checkatrade 10/10 rating give you additional peace of mind. All our installations meet strict standards for safety, energy efficiency, and quality.

Can you help with planning permission for conservatories or extensions?

While we’re not planning consultants, we have extensive experience with permitted development rules in Havant, Waterlooville, and across Hampshire. Many conservatories and extensions don’t need planning permission if they meet certain size criteria. For projects that do require approval, we can recommend trusted local architects and submit technical drawings on your behalf. Our team will guide you through the process during your initial consultation to ensure compliance with all regulations.
