Frequently Asked Questions

We’ve done our best to answer some of the most frequently asked questions below. Feel free to get in touch if you require additional information about any of our services

Our Company

We are based in Norwich, Norfolk and service customers across South Norfolk, North Norfolk, Suffolk and Kings Lynn. You can view a full list of our service areas here.

Our office is based on Sweetbriar Industrial estate in Norwich and we are in the process of creating a boutique showroom here. Viewings are by appointment so just get in touch in the usual ways to book a visit. If you are interested in viewing a warm roof or any other products in situ, we would be happy to arrange a visit to a nearby property we have worked on in your area.

Yes, we do. We want to be as sustainable as possible and as such we have an outlet store where we list any windows and doors we cannot use. All of these products are in perfect or near-perfect condition and can be found on our Habify Outlet page.

Yes, we do. We offer finance through a company called Kanda – speak to a member of the team for more information.

Windows

We use A-Rated double-glazed glass units as standard for our windows. If you require extra insulation, we can upgrade these to triple-glazed. Talk to our sales team about your options and prices.

A true aesthetic rival to original timber, our flush sash windows are ideal for conservation and heritage locations, whilst adding an elegant, clean look to new build properties. Typically, they can be used within listed buildings but it’s always best to consult with your local planning officer to make sure as each location and property is different. We also supply and fit heritage-style aluminium windows which are a great alternative to traditional steel. If you require timber or alu-clad, take a look at our Rationel Forma Heritage range.

In line with our environment policy, all waste generated by the removal of your old windows will go to a local waste disposal company that will recycle 99% of the product with the remainder being used to generate power as electricity and heating.

Yes we do. Our ranges of heritage style aluminium windows, uPVC Flush Sash and uPVC Vertical Sliding windows can all be fitted in conservation areas and some listed buildings, too. If you live in a conservation area let us know when we survey your property and we will be happy to help.

Yes, we do. Our Rationel range of windows includes an all timber frame, as well as a timber frame with aluminium cladding, for extra protection from the elements.

Yes we do – We supply Velfac windows and Rationel Forma and Rationel Aura windows, all of which have alu-clad (otherwise known as Composite) options.

All windows or doors fitted since 1 April 2002 require a valid FENSA certificate or a building regulations certificate. A FENSA certificate confirms compliance with building regulations and we issue this once work has been completed, so it’s all done for you.

If looked after properly, double glazing can last for anything up to 30 years, but it is a good idea to give your windows a check over if they are 20 years old. More information can be found in this blog

A lower U-value means a better window for retaining heat. A window’s U-value is a measure of how much heat can pass through it. Lower U-values indicate less heat loss.

A G Value refers to how much heat from the sun’s rays passes through a window. A higher G value means more solar heat can enter the home. Homeowners often prefer windows that allow more sunlight to reduce heating costs.

Doors

The short answer is ‘Yes’! Chat to our sales team about designs for wider entrances that feature matching glazed side panels. We can also do double doors for a high-impact entrance. Explore our range of doors here.

We recommend that you apply oil to the hinges of all doors once a year to keep them in tip-top condition. It is also a good idea to vacuum in and around the door threshold area to keep it clear of gravel/ other bits and pieces. Other than that, the only maintenance your door should require is the occasional sponge down with a damp cloth to remove dust and grime.

All replacement windows and doors have to be registered with FENSA. If you ever come to sell your house, the purchaser may require FENSA certification – so it’s best just to do it. We will take care of this and you will receive your certification shortly after installation.

We offer a range of heritage-style aluminium doors in the Crittall style made famous in the Art Deco era. View our range here.

Yes, supply and fit both entrance and patio doors. we take care of the whole process from survey to installation. We can help you with building regs, too.

Yes we supply and fit aluminium bifolds. We also do aluminium sliding doors and french doors, too.

Conservatory Roof Replacements

Warm Roof installations are an innovative home improvement that can transform a conservatory into an all year round living space and provide incredible energy efficiency to your home. Warm roof conservatories give you the customisation options you need to make the space your own through tile colour and the addition of glazed panels or Velux windows for an extra wow factor. The long-term benefits make a Warm Roof a property investment, increasing the value of your home from its ‘extension’ like design, and reducing your annual heating bill through its temperature regulation.

Our warm roof system is a quality-engineered, fully ventilated structure that exceeds building regulations to all thermal and structural standards. 125mm of Celox insulation sits within the roof structure to eliminate any cold bridge between the rafters and roof covering, keeping the cold air out in winter months and preventing excessive heat build-up within the summer period – This is what gives the conservatory that perfect year-round environment.

Every project is different, but typically the whole process takes 3-6 days to complete. Due to the roof’s design and our installation process, you could have a watertight installation within the first day, depending on the size and complexity of the project. The approach we take to remove your roof, prepare the conservatory frame and begin the construction has been optimised over time to be as efficient as possible.
Habify uses Guardian’s market-leading Warm Roof System that has been subjected to independent thermal analysis. The analysis takes into account the entire roof assembly, including cold bridging, to give a true U-value as required by Building Regulations. The roof is a solid, tiled roofing system engineered using weatherproof materials and benefits from superior insulating properties. Many other roof conversion solutions state a similar U-value, but this is theoretical unless the entire assembly has had thermal testing.
The Guardian Warm Roof system carries LABC & LABSS certification, meaning it is Building Control compliant throughout the UK & Scotland. The process should proceed faster, smoother and without complication, covered as part of our full service with the assistance you require for related enquiries.

When purchasing a conservatory warm roof our project manager and surveyor will be your direct contacts. During the project, you will have a dedicated customer support advisor and direct contact with our project manager for any issues or enquiries. Our on-site workforce will also be available to assist you if needed. Our dedication to your property from start to finish is of utmost importance, there will always be someone available to help you when you need it.

Typically a conservatory roof replacement starts at around £6970 for a 3×3 metre conservatory. On our roof page, we have a cost calculator tool which will give you an instant guide price based on your conservatory measurements.

SIP Extensions

A SIP extension or SIP Panel Extension is a home extension made from Structurally Insulated Panels. They consist of an insulated foam core sandwiched between two structural facings and are used to build both commercial and residential structures, eliminating the need for traditional building materials such as brick/ block. In addition, a building made from SIP panels doesn’t require the deep foundations required for a traditional build, which can be time-consuming and messy.

Not necessarily. While a SIP extension will likely save you money on labour costs, the overall cost is fairly comparable to that of a traditional build. However, if downtime will impact your costs, you may well make a saving with a SIP Extension. This is because they go up in around 1-2 weeks rather than the months of disruption you can experience with a traditional extension build.

Usually, yes. Get in touch to book a free survey and we will take a look.

Structural insulated panels (SIPs) are highly efficient and eco-friendly building materials. Made primarily from renewable timber, SIPs require significantly less energy to produce compared to traditional materials like concrete and steel. This makes them a sustainable choice for construction projects. In addition, they make energy-efficient buildings, meaning less need for central heating.

As a general rule, a single storey SIP extension will be up and ready to use in 1-2 weeks.
