    “I just wanted to say how pleased I am with the windows and doors.  Your kindness, service and whole experience of dealing with you was first class.  From the very first phone call til the last visit to check I was satisfied was incredible.  Your whole team were wonderful to my family and I enjoyed every moment dealing with you.  Thank you to all of your team for everything.”

    Jules Healey

    “I’ve just had my new composite door installed by the team at Chiltern home improvements and im blown away by the quality at such a competitive price. More impressive than the door itself is the service levels ive experienced throughout the whole journey. Tracy has been fantastic and kept me up to date with regards to the timescales for delivery and installation. Ken & Matt where true perfectionist and a joy to have around. If you’re looking for Windows and doors i would certainly give them a call and doubt you will look any further.

    Thanks again for all your help and will be in touch when I need you again.”

    Matt Goss

    “STOP and READ THIS.
    We only needed one small window replaced and Tracy made us feel like just as an important client as a multi-million pound mansion house owner. Not only are they great to deal with, the installation was efficient and very tidy. I rarely write reviews but I have to for Chiltern as I’m so impressed by their high level of customer service – it’s simple – use them and you will not regret it. We will in the near future be getting some other windows replaced and we will be using Chiltern. Thank you Tracy and the team!”

    Jon Spier

    “Really pleased with our new windows. Tracy helped us work out the style we needed with astragal bars, double openers and safety catches, and the fitters Ken and Matt were friendly, hard working and professional. It took less then 3 days to install 11 new units in our town house and they look great!.”

    Jeanne Martin

    “Great job of refurbishing my mothers conservatory, from crumbling, leaky mess to smart usable living space. Helpful from start to finish, despite having to deal with a crooked wall and delivery problems the guys were professional and courteous throughout, working late to ensure the job was finished on time. Wouldn’t hesitate to use again or recommend.”

    Tony Mcmenamin

    “Very pleased how easy it was from start to finish to get a single replacement window. No call centre or sales-ey stuff, Tracy knew what I needed over the phone, got it measured and installed without any hassle. The two guys who did the measuring and installation were super nice as well. Definitely recommend this company.”

    Sharon Stevens

    “From start to finish we could not fault Tracy and her team at Chiltern Home Improvements. They quoted us the best price for a new back door, had the guys come and measure in advance and the fitting was done within a couple of hours, all to an excellent standard and even cleaning up after themselves. You will not be beaten on price or service in Hertfordshire.”

    Matthew Berry

    “These are really genuine people to deal with – really friendly and helpful.”

    Amanda Tyas

    “Amazing results, professional service and top top quality fixtures and fittings x”

    Kally Moorhouse

    “We have been customers of Chiltern Home Improvements for years and quite frankly would not use anyone else. Lovely family run business that is reliable and consistent in everything they do.”

    Sarah Gibbons-Cook

    “Quality service from genuine and ‘down to earth’ people – strong tea with two sugars for Ken and a black coffee with no sugar for John. Happy days….”

    Dean Isherwood

    “The installers came on time and were very polite and explained where they were going to start and how long they expected to take. They hardly stopped and were very clean and tidy workers. What I am trying to say is a big thank you to you and Chiltern for a service second to none and we have no hesitation in recommending you and your service.”
