Q: I’m very concerned about security. What reassurances can you offer me?

With every window or door installed by Harp, comes the peace of mind in knowing that your home and your possessions are protected by products that are proven in their ability to withstand forced entry. Our uPVC and aluminium casement windows and residential doors, French doors and composite doors are all Secured by Design accredited. Secured by Design is a range of national Police projects committed to home security, and all accredited products have been tested to the very latest BS:PAS security standards published by the BSI. Please feel free to contact us for any further information about the security of our products.

Q: I live in a period property and I’d love the benefits of double glazing, but can’t fit just normal double glazed windows because I’m in a conservation* area. What can I do?

We install the Sheerframe Environmental sash window and the Universal sash window, both are virtually indistinguishable from timber sash windows, yet are top spec, maintenance free, double glazed, easy clean and high security. You even have the option of an authentic style Georgian glazing bar and arched tops. Both our Sheerframe and Universal sash windows have been approved for the Oxhey Village Conservation area.

We are also official selected partners for Evolution Windows. They maintain the look and feel of traditional wood in the style of Georgian and Tudor but have all the advantages of state-of-the-art modern window technology. Handcrafted and tailor-made from only the finest materials, they offer outstanding energy saving, exceptional weather proofing and unequalled low maintenance.

Our Sheerframe, Universal and Evolution windows have been installed in conservation areas, and are the ideal choice for the discerning homeowner who does not wish to compromise on quality or choice.

*If you live in a conservation area, you may need planning permission to replace your original windows. Contact your local authority for details.

Q: Can I look at some previous installations that you’ve done?

Absolutely! We have many photographs that have been taken during installations and we are more than happy to email you photographs of installations in your area or that have a similar specification to your property or window type. We can also provide you with locations of recent installations which you are able to view. In addition, you can also see the results of our customer satisfaction surveys in our showroom at Bushey Arches and see genuine up-to-date customer reviews on our Checkatrade page.

Q: Do you make aluminium windows and doors?

We manufacture windows and doors using the Aluk Blyweert Beaufort System which is installed direct into brickwork.

Q: Are your windows energy efficient?

Yes! Our Rehau Total 70c uPVC casement windows are available with an A+ rating as standard. Aluminium and our Sheerframe uPVC box sashes with the authentic deep bottom rail (note not all makes of sash windows have a deep bottom rail) are B rated. Your quote/contract should always clearly state what energy rating your products are, but we are happy to clarify in all instances.

Q: What does this rating actually mean?

Simply put, this will determine how well a product will perform the functions of:

  • Helping you contain and conserve heat within your building in the winter;
  • Keep out the wind;
  • Resist condensation;
  • Contribute to improved sound insulation.

Our REHAU TOTAL 70c window (our standard uPVC casement window) is manufactured by Shepley and has been awarded an A+ WER licence from the BSI. The BSI Kitemark scheme for Window Energy Ratings (WER) is based on the approved document L1B of the Building Regulations which came into force on 1st October 2010. This stipulates that all replacement windows must have:

  • A Window Energy Rating (WER) of at least band C or
  • A declared U value of 1.6 W/m²K

The BSI Kitemark scheme for WER provides a quality assured process and supporting audit trail from simulation of the WER through to installation and is therefore accepted by Building Control Bodies. The WER Kitemark label can be used on the product down the supply chain ensuring that retailers and installers can use Kitemark Window Energy Rating certified windows.

Q: How long will it take for my windows/doors to be installed?

For standard installations we usually quote a lead time of around 6 weeks. However in reality, installation can often be quicker than this, it depends on the time of year and our current workload. If a customer needs their installation completed by a certain time, we will always do everything we can to ensure that takes place.

Q: I wanted timber windows but they are so expensive! What is your timber alternative window?

This is the Evolution Storm™ and Flush range of timber alternative windows. These windows truly stand out with a quality of finish that is unsurpassed:

  • The frames are all butt jointed using the same process of manufacturing a timber window; there no welded corners on the outer frames like in a standard uPVC window;
  • Windows have a timber grained finish in white, cream, black, natural wood or any colour that you require;
  • The internal edges on the outer frames are all ovolo with the exact detail of a timber window;
  • The external edges are a pencil round finish with a putty line edge to the glass;
  • Traditional style handles and peg stays complete the authentic look.

You can see examples of our Evolution installations in our gallery, or come and see our display windows in our showroom and appreciate the difference for yourself.

Q: What sash windows do you do?

We manufacture our Sheerframe Environmental Sash windows from our factory in Watford. We also install our Universal sash window which has a woodgrain effect foil. Both are virtually indistinguishable from timber sash windows, yet are top spec, maintenance free, double glazed, easy clean and high security. You even have the option of an authentic style Georgian glazing bar and arched tops. Both our Sheerframe and Universal sash windows have been approved for the Oxhey Village Conservation area.

Q: I’d like someone to give me a quote but don’t want to be hassled with high pressure sales or annoying salesmen!

Please don’t worry, we never engage in these tactics. We spend around 30-40 minutes with you, discussing your options and measuring up; we will then provide you with a quotation. We don’t keep ringing you up or hounding you for a decision and we fully respect your privacy at all times. That’s a promise.

Q: Who will fit my windows? Do you have your own teams of fitters or do you subcontract?

We don’t subcontract; we have our own teams of fitters who have been with us for many years now. They will treat you and your home with both courtesy and respect and will even clean up after themselves. We receive a lot of complimentary feedback about our fitters, see our testimonials page to see what our customers have said.

Q: What happens if I have a problem after installation?

Simply give us a call and we’ll send out our service engineer to rectify it for you. If you’re within your ten year guarantee period there will be no charge for this service. As a WHICH Trusted Trader,  we also offer a clear and transparent complaints procedure – we hope you will never have to use this of course! In the highly unlikely event that we are unable to resolve your complaint using our own complaints procedure, as a Which? Trusted trader we use Ombudsman Services Ltd for dispute resolution.

If your question hasn’t been answered here, please do not hesitate to contact us – we’re here to help!
