Wow!   What a difference a day makes!   Actually three days.   That’s how long it took to replace all the windows in our house.

The whole process of replacing our windows has gone like a dream (literally).   After placing our order, the measure-up was carried out whilst our son (who was working night shifts) slept through the taking of dimensions and never knew a thing about it.

The fitters were efficient and professional, removed the old frames, installed the new and returned all roller blind brackets that were left on the frames.   They cleaned up after themselves each day and the only way you knew they had been was the new window frames and the warmer house.  After the windows went in, my wife commented “it was like having a new house”.   Thanks Windseal! That’s saved me several thousands of pounds in relocation expenses, more than the cost of the windows.

Since the windows went in, the house is warmer!   It is now mid-January and we have only had our central heating on very early in the morning whilst in the shower.   After that the house has remained comfortable for the rest of the day.   We still haven’t operated our central heating through the day during this winter so we are already saving on our heating bill.

If you’re thinking of replacing your windows, I thoroughly recommend Windseal Double Glazing.   Their product and service are second to none.

We have now lived with Windseal Double Glazing, installed by yourselves, for the last 8 months. During this time we have been absolutely delighted with the results of your work in the following ways:-

  1. we wanted them to be made in the 1930’s casement shape, and this you achieved
  2. the leaded lights of the period were reproduced with great accuracy
  3. additional leaded lights were added to the front bedroom windows
  4. other people who have visited the house have commented on the quality of the work
  5. the white of the window frames have lightened up all of the rooms
  6. the outside of the house has been freshened up
  7. they have cut down on the amount of traffic noise
  8. they have given a ‘calm’ atmosphere to the rooms
  9. the easy openings give ready access for cleaning both inside and out
  10. the opening in the big windows mean that I can still climb out onto the bay
  11. the smooth frames mean that they are easy to clean
  12. the front porch, the “tardis” has made a tremendous difference to the heat retention when the front door is opened, plus being somewhere to stand when opening the main front door from the outside

However, the main reason that we are so pleased, is the difference they have made to the heating in the house.   We were really surprised at how much heat retention there was and how little we switched on the heating, compared to before the installation.

We also want to say a big “THANK YOU” to the men who carried out the installation, for their professional and helpful attitude during the time they were here.

Just want to thank all players with regard to the insulation of my door and window today. The service throughout has been excellent. This goes from the office staff, to the fitters.  Many thanks

Glenn Fleet


I had a patio door and some windows that had misted over replaced by Windseal double glazing.  The fitters arrived when they said they would, the work was completed to my satisfaction quickly and cleanly.  I have to say the fitters were very professional and good ambassadors for the company. The patio door will enhance my dining room especially when we have days in the summer when it can be fully opened. I would certainly recommend Windseal for any type of double glazing and window replacement. Thank you to you all at Windseal

Testimonials. Satisfied clients make us happy.

I have recently had a new from door and surround supplied by Windseal Double Glazing. I was very grateful for their kindness, in person and on the phone. When getting estimates and measurements they were very helpful in giving me advice and explaining in full all that would be done. When the door was fitted, the care and attention that were given to my property and to the service that they provided was exceptional. I have no hesitation at all in highly recommending them. I am hoping to have further work done by them in the near future. Thank you so much to Kevin Moore and his team.



I would like to express my thanks to Liam, Donovan and Harry for a fantastic job when they replaced all my windows,doors and patio doors. The attention to detail was much appreciated along with their humour and work ethic. Would definitely recommend the company to any one who want’s a first class job .

Mr Jephcote



Would like to say a big thank you to Liam and the guys for all their hard work in fitting our new windows.  They have done an amazing job and we are absolutely thrilled.  I would have no hesitation in recommending Windseal for anyone who is in the market for replacement windows – we found the whole process to be smooth from start to finish.  The guys were professional, approachable, efficient and very tidy.  Superb!

Mr & Mrs Malin


Many thanks to all involved great job done would recommend to all.

Cath Davies and family


Just a quick note to thank you for all your work in refurbishing what until recently was our rather sad-looking conservatory. The new double glazed windows and doors look really good, plus the new window sills and exterior cladding finish the job off just perfectly. We have also noticed that the conservatory is a lot warmer and more comfortable these days, even when there is no sunshine.

The work was carried out quickly, efficiently and cheerfully and we were particularly impressed with the way your workmen took away all the rubbish and left the place clean and tidy. There was nothing for us to do at all, except sit and enjoy our new warm, light and airy “garden room”.

Mr & Mrs Smith


Kevin, just a quick note to say how pleased we are with the new windows and door you have recently fitted for us. I am particularly pleased with the level of care taken by Liam and his workmate to the installation leaving me with no decorating to do, although the wife thinks differently. Not only was the work done neatly but also quickly and on time as promised. I am now in the position that, thanks to the more efficient glass in the windows, her indoors doesn’t want the heating on every night. I would not hesitate to recommend your firm to anyone and once again thank you to you and your team.

Maurice Farndon



We recently had doors and windows fitted by your staff. I would have no hesitation in recommending you product or your fitting team. They had a really difficult job to do at our house many pipes and cables had to be negotiated to fit both doors and windows. The completed job was excellent and the fitters tidied up afterwards so there was no mess. A very professional job.

Lynne & Richard Gibson


I was more than pleased with the way the job was done good friendly fitters the patio door was of excellent quality and your fitters left the job very clean and I would not hesitate in recommending your company to anyone.

Mr D Glover
