What people are saying about Window Seal Systems!

"Previously we had a lot of complaints about noise coming from the surrounding streets but since the installation of the Wind-Do Seal Secondary Glazing System we have not received one complaint about noise from our guests. Excellent result!"

Jimmy Kealy, Hotel Manager, Jurys Inn, Parnell Street, Dublin 1


"This company stood out for both quality and price! We are absolutely delighted with our decision to invest - we have saved already a fill of oil after just 3 months; not to mention the drop in noise level from passing traffic!" 

McCormack Solicitors, 4 McElwain Terrace, Newbridge, Co. Kildare

"We manage a number of apartments in Dublin city centre. We were having issues with street noise in several of the apartments that was causing on-going issue for our tenants. We had secondary glazing installed by Wind- Do Seal Systems and the difference has been dramatic. I was very surprised at the level of noise reduction achieved by the glazing. I would definitely recommend this company and its product"


Stephen Mc Govern | Managing Director, Dublin City Rentals

"Harold McManus came to Cork and measured up exactly what was needed. He was able to provide me with a quote immediately which was a great help. My secondary glazing was installed a couple of weeks afterwards. I am really happy with the quality of them. They are worth every penny and a great investment in our home. I will definitely use this company again and am already planning the next project with them."


Margaret Moore, Old Douglas Rd, Cork 

''Just a short note to thank you so much for providing such an excellent service with your Secondary Glazing System. I am delighted to say that the road noise that prevented us from using our front bedrooms has been pretty much eliminated, thanks to the Sound Proofing work you did for us. We also find that the rooms feel so much warmer and cosier that we haven’t had to put the heating on anywhere near as much as before.  Many thanks for such an effective solution to our noise problem and we will be sure to recommend the Window Seal System to our friends and family''
