What Our Customer's Are Saying About Us...

October 2018

We had one of our windows done as an experiment.

We live on a busy main road.

It certainly reduced the noise from the traffic. As a result of this we then had four more Windows done. It has been a big success.

The gentleman came, measured the windows and gave us a price. We decided to go ahead. We were given an approximate date that the secondary glazing would be ready for fitting. On both occasions they were slightly early.

All the fitters appeared to be very competent in their job. They did not make much mess, but what they did make they cleaned up before they left. An excellent service. Thank you very much.

IG Spilsby - Oct 2018 - 12th October 2018

The job is excellent really well fitted and we noticed the difference in the acoustics straight away, and based on how well its fitted we should notice the performance in thermal as well. The looks are great really does look like its one unit with the existing windows. Very very pleased

Adam and Tim were brilliant very helpful very clean and proud of their work. Adam helped me out with drilling a hole to relocate the telephone line. Top job by them.

BC Bebington - Oct 2018 - 4th October 2018

Thank you very much for arranging for the installation to be carried out so quickly. The chaps were very careful and efficient and we are very pleased with the unobtrusive design. It may be our imagination, but an hour after completion the room feels warmer already.

We have two neighbours who may contact you once they’ve been to see our panels.

The product is excellent and the installation was carried out in the most professional manner. Unfortunately, we are not good on names but please thank the installers for their quality installation with absolutely no mess- some of the single glass replacements were to say the least challenging.

AC Telford - Sep 2018 - 25th September 2018

I just wanted to take this opportunity to express my heart felt thanks for an outstanding service, as well as for such a superb product. Combined with such professional installation.
Rarely does the purchase of a single product have such an extra ordinary effect on the quality of daily life & well being to such a degree. However, in this instance the secondary glazing has provided near perfect 100% sound proofing. It has utterly transformed my office bedroom into a sanctuary of calm, of deep peace & quiet. The difference is incredible & the effects beyond my expectations & hopes.
Since installation of the secondary glazing I now no-longer hear any of the following since installation.
• No traffic noise from Kirkstall road.
• No Ambulances or Police sirens (which were especially intrusive)
• No House alarms (which can ring for hours)
• No Low flying Aircraft or jets
• No car alarms
• No music from rental tenants in the street
• No loud talking & conversations in the street at night
• No disturbance from the neighbour directly over the street at No.28 (late night parties).
Note: Have now stopped having to use ear plugs just to get a normal nights sleep.
My room has become a space in which its now a great pleasure to spend time in. I have needed this deep tranquillity ever since being bereaved & having moved back to Leeds. About three years ago. The stress & anxiety I used to suffer from in the past few years, due to noise nuisance has literally gone. Knowing that the secondary glazing is a permanent fix is also very re-assuring. Having broken sleep is awful but these concerns are all ancient history now.
My only regret is that I didn't have secondary glazing fitted two or three years before when noise was causing me even more distress & annoyance.
