S. Minihan – Harp Customer
    • “I have to say I have been impressed with HARP from start to finish. I was guaranteed the best price from John at the beginning, There was no hard sell or tricks, Just simple and honest. I ordered 1 window to replace my old bay which I was advised would take 6 weeks from ordering. My window arrived slightly earlier than anticipated and was fitted without delay. The fitting team worked in a clean and tidy manner, were punctual and had a great attention to detail.”
      J Anastasia, Watford (Checkatrade – read more here).
    • “Initial consultation arranged to suit me and also the surveyor came early so I didn’t have to take time off work. Fitter was excellent. Arrived on time and tidied as he went. Would highly recommend this company.”
      S Peskin, Chesham (Checkatrade – read more here).
    • “We set out to have our ancient double glazed units replaced with some trepidation as we are in an older property. We needn’t have worried, the service and more importantly, the fitting, was excellent. Our fitter didn’t stop from the moment he arrived, he took a real care in making sure the finish was just right and we were also pleased that Harp had recognised on their survey that our old windows were substantially out of fit, hence the reason it was so draughty! We have no hesitation in recommending them, they were to budget and accommodated the date we wanted them to be fitted. Many thanks!”

Andrew Foster – Harp Customer
    • “Thought I’d drop you a note to say thank you for completing such a great job on my double-glazed windows! The men that fitted the windows were extremely hard-working,finished the job in only one day (without any breaks!) and the end result is extremely professional, well-finished and I didn’t even need to hoover! I would be grateful if you could pass up my thanks on to them. I wouldn’t hesitate to recommend Harp to friends or use you again in the future and am extremely satisfied with the timeliness and quality of your work.”

      Mrs Brogen, Bushey.
    • “This is the second time we have used Harp Windows and, as before, can have no complaints. From the initial inquiry through to completed installation we received a professional service. I believe the price of our work to be highly competitive. Our property was left tidy throughout the period of installation and we are happy with final installation. The workmen even repaired some broken skirting that I’d been meaning to do for ages! I’ve recommended Harp Windows to friends and family in the area who are thinking about getting new windows or doors, and will continue to recommend them.”
      Mr Bezdel, Watford.

We would like to commend you on an excellent service throughout. Every part was easy and we still can’t believe how quick it was … very clean, tidy and friendly. We will have no hesitation in recommending you to all …

M & L Sheppard – Harp Customer
    • “The job was more complex than usual as three of the windows were into existing dormers and a bay. The windows were fitted accurately and neatly with minimal making good. The work areas were left clean and tidy and Terry and his mate were very friendly and cheerful. Alan the design engineer was especially helpful with the design and manufacture of the hardwood sills and accurate detailing for the bay window.”
      Mr Weller, Rickmansworth.
    • “We are very pleased with this company and highly recommend them to others. They are professional, polite and put customers first.

Thank you Harp windows, Watford for doing such a fantastic job.”
