Windows, Doors & Extensions

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.

2. How long does it take to install a conservatory in Waterlooville?

The timeline for conservatory installation depends on the size and complexity, but our hup! extensions are typically completed 5 times faster than traditional builds. Most standard conservatories in the Hampshire area take 2-3 weeks from groundwork to completion, with minimal disruption to your home. We’ll provide a precise timeline during your free consultation.

3. Are your composite doors more secure than standard uPVC doors?

Yes, our composite doors offer superior security features including multi-point locking systems and reinforced frames that meet police-approved Secured by Design standards. They’re constructed with durable materials that resist forced entry much better than standard uPVC doors, making them ideal for front entrances in Portsmouth and surrounding areas.

4. What's the difference between fascias and soffits, and when should they be replaced?

Fascias are the vertical boards behind your gutters, while soffits are the horizontal boards underneath the roof overhang. You should consider replacement if you notice rotting, peeling paint, water damage, or if they’re over 20 years old. Our uPVC roofline products in Havant and Waterlooville never need painting and come with a 10-year guarantee against weathering.

5. Can bi-fold doors be installed in older properties in Hampshire?

Absolutely! We regularly install bi-fold doors in period properties across Portsmouth, Havant, and Emsworth. Our team can create a structural opening that maintains your home’s character while providing modern thermal efficiency. Aluminium bi-folds are particularly popular for older homes as they offer slim sightlines that complement traditional architecture.

6. How much does double glazing replacement cost in Fareham?

The cost of double glazing replacement varies based on window size, style, and material. For a typical 3-bedroom home in the Fareham area, complete uPVC window replacement usually ranges between £3,000-£6,000. We offer free, no-obligation quotes and can discuss financing options. Remember, quality window replacement improves energy efficiency and can save on heating bills.

7. What makes hup! extensions different from traditional home extensions?

Our hup! extensions are pre-manufactured offsite, which means they’re built 5 times faster with minimal disruption to your Hayling Island or Portsmouth home. Unlike traditional builds, there are no weather delays, less mess, and guaranteed timelines. These stylish extensions come with the same quality and guarantees as our other products, just with a quicker, cleaner installation process.

8. As a FENSA registered company, do I need separate building regulations approval?

No, our FENSA registration means we self-certify that all window and door installations comply with building regulations in Hampshire. You’ll receive a FENSA certificate upon completion, which is important for home insurance and future sales. This applies to all our work in Portsmouth, Waterlooville, and throughout our service area.

9. Can you replace just one window or door, or do I need to do the whole house?

We’re happy to handle single window replacement or door installations throughout Havant and the surrounding area. Many customers start with one problematic window or door and gradually replace others. We can match new units to your existing ones if needed. No job is too small – we provide the same quality service whether it’s one window or a whole-house upgrade.

10. What maintenance do uPVC windows and composite doors require?

Our uPVC windows and composite doors are designed for easy maintenance. Just wipe them down with mild soapy water occasionally, and lubricate moving parts annually. Unlike other materials that may require ongoing upkeep, our uPVC and composite products retain their appearance for years with minimal care — perfect for busy homeowners in Hampshire who want durable home improvements.
