I recently had my windows replaced by Window Wise. They were highly professional in the lead up to the installation, making sure that I was aware of the progress of the order and who would be completing the installation. Oli and Adam were absolutely amazing. They had a huge amount of experience of replacing windows in Bolnore Village. There workmanship was fantastic, they were polite and friendly and left absolutely no mess. What a fantastic team you have with Oli and Adam. I would have no hesitation to recommend Window Wise to my friends and relatives. Thank you.

Excellent communication from start to finish.Tom, Martin, Oli and Adam all had an enthusiasm and knowledgeable approach and I felt in safe hands throughout. I also thought the costs were very reasonable, certainly not the most expensive and not the lowest, but only a small premium up from the lower end. I like that they are Fensa registered too.

I cannot recommend this company highly enough, from the moment of first contact to the aftercare the customer service has been excellent. I’ve had a few jobs done with the house recently and this company were by far the most proficient and professional. Also the installers, Olly and Adam, were excellent in their conduct and a pleasure to have around. Great job.

The thought of replacing my crumbling conservatory was daunting but Window Wise held my hand, from beginning to end, making the whole experience easy and stress free. Such a professional and friendly team and the installers were extremely hardworking, efficient and tidy. I couldn't be happier with the result - a superb service. Thank you!

First class service from beginning to end. Tom, Sally, Martin and the A Team (Ollie and Adam). A special thank you to Ollie and Adam who went over and above to help. Finding years worth of birds nests when taking a window out was a shock but not only did they clear up, clean, put the new window in, they boarded up the entrance. A professional job with customer service. I will back in touch for more work in the future. Thrilled with the windows and front door. Thank you all.

Really happy with the work replacing the units in our conservatory. Everything was on time and to a great standard. The fitters were polite and efficient and even rectified quite a significant issue we had with the roof. Very pleased.

We thank window wise for the professionalism that they used in getting to fit three new windows. From when they came to estimate until the windows were completely installed, the service was first class. Adam and Oli fitted our windows on 19th October and work was as professional as all the others that have attended us.. many Thanks Gordon & Valerie

Just a lovely company to deal with. Professional, high quality and Chris and Steve were fantastic with the installation (thank you both). The windows and doors look great in our house and I would definitely recommend Window Wise to my friends.

Delighted we are with our new windows. From beginning to end, working with window wise has been complete joy. Gavin gave great advice and was so patient (I am quite indecisive!). Quotes were received quickly and rewritten with the same speed as I changed my mind again and again. I was never ever made to feel like a problem. The survey was straightforward. We were kept up to speed with the wait times. Finally, the fitters were outstanding. An absolute pleasure to have in the home! They got on with the job, were attentive to detail and they tidied up at the end of the day. To be honest, I was dreading the upheaval... but needn't have worried at all. There's no doubt ... it is a lot of money BUT totally well worth every penny.
