Find out how others have transformed the peace, warmth and sanctuary of their property for the better.  Here is just a small selection of great reviews we’ve received in recent months.

Bobby Pec – Homeowner

“I was so surprised at how effective it is at stopping sound. It has made my room almost completely silent and has completely wiped away the white noise of the road. For the first night ever, I’ve slept without earplugs.”

Catriona Johnson – Homeowner

“We had Granada’s secondary glazing product installed in our Grade II listed house and we are very happy with the results. We live on a busy main road and noise pollution has been drastically reduced. Being a very old house, installation wasn’t a straightforward job but the team worked very hard to complete it in a day. I’d highly recommend Granada.”

David Oldroyd – University of Leeds

“Granada has fully achieved their part of the brief providing a unique solution to the thermal issues at Leeds University. Their secondary glazing is non-intrusive and has helped to discreetly renovate this Grade II listed building.”

Giles Clements – The Window Centre

“We’ve been one of Granada’s trade partners for several years now and have always found their products to be of exceptional quality. We work closely with our local Business Development Manager who ensures we’re kept up to date with the latest product improvements and releases, installation training and marketing literature.”

“These guys are so good we’re using them again for our other meeting rooms as the difference in noise reduction is incredible. For all your commercial glazing needs, talk to them.”

Graeme Payne – Black Knight Secondary Glazing

“The Granada secondary window is the best of its kind; the design range and working parameters allow us to cater for any type of project in the marketplace and it is always built to a consistently high standard. We find all of Granada’s staff to be very friendly, responsive and helpful; nothing is too much trouble for them.”

John Mitchell – Homeowner

“Great communication and prompt, friendly service. We had secondary glazing fitted throughout our 17th century, listed farmhouse and it is noticeably warmer, but most importantly for us the condensation has been massively reduced!”

Les Gold – Goldstar Double Glazing

“Having dealt with Granada for many years, we have enjoyed a good relationship and strongly recommend them. The products and service are excellent, they adhere to delivery promises and return pricing options quickly and efficiently.”

Lucy Rowlands – Homeowner

“I had secondary glazing fitted in our Victorian flat with very old, big windows in for both sound reduction and thermal retention and I’m so happy that went with Granada. The glazing works a treat and service was over and above, fantastic from start to finish. The team are really friendly, super knowledgeable about the product and the fitting team even borrowed my vacuum to clean up after the fitting – brilliant!”

Mark Cox – BAM Construction Ltd

“We have employed Granada on a number of projects under the P21 framework in Sheffield. Their role in introducing blink glass to the Critical Care Unit was an industry innovation at the time, and a distinct benefit to the project as a whole.”

Shana Mona Khan – Homeowner

“When I saw the end product, I was literally speechless as it was so beautifully finished and in keeping with the original frame.”

Simon Lord – Houston Cox Specialist Joinery

“Granada’s secondary glazing systems have provided a unique solution to the acoustic issues presented by a key city centre location whilst remaining discreetly sympathetic to the renovation of this Grade II listed building.”
