We have been badly let down
Disappointingly we have to leave a negative review. In mid-December 2020 we commissioned a replacement purpose built Victorian style conservatory in hardwood at a cost of nearly £29,000 and paid a deposit of £7,160 on the basis of it being fitted in around 10 – 12 weeks at the end of March. The terms and conditions provided by Hertford Glass included our approval of manufacturing drawings prior to commencement of manufacture. After 3 or 4 visits from 2 different people we became anxious as the drawings weren’t forthcoming and time was marching on, even though we anticipated some delay due to Covid. There were many verbal apologies and excuses for the delay in producing the drawings and we started to lose confidence. We tried to speak to Managing Director David Bailey but he did not return our calls. Eventually, some 15 weeks after placing the order we received a drawing of a standard rectangular casement window which did not represent the conservatory that we had ordered. On 28th March we emailed to re-confirm our request to see proper manufacturing drawings and the following day received a rather curt reply saying they were cancelling the order as their supplier was unable to provide detailed drawings. They have subsequently refunded the deposit having held it for 15 weeks. If we had known at the beginning they would not comply with the terms of the agreement we would not have placed the order.

This was not the first time we have used Hertford Glass they installed replacement windows and doors in our previous property and also installed windows for an extension we had built. We have had 2 bedroom windows replaced in our new property one of which is a bay window, lovely looking windows with integrated blinds. We are extending into the loft space of the property and will definitely use Hertford Glass for the new windows and also to replace the rest of the existing windows and doors at the same time. Work was done within agreed schedule and budget. The installation was carried out professionally, efficiently and in a friendly manner. Old windows were taken away and in both bedrooms the area being worked in was tidied before leaving.

Excellent work carried out on replacement windows in our flat.
Customer Service
We obtained 3 quotes for the replacement of all windows in our ground floor flat which included a large bay window. We had to comply with the overall look of our development in respect of sight lines etc. & Management consent had to be obtained. We chose Hertford Glass, although not the cheapest quote, but they offered the most professional approach & we could look at the products in their local Hertford showrooms & discuss options with staff there. All visits for measuring & quotes were done in a timely manner & options discussed on site. Job done in two stages. Excellent & considerate workmanship by the fitters. Site left neat & tidy at all times. Delighted with the product fitted. Bay window, in particular, is a treat. The fitted windows are much more secure & robust than the original ones fitted by Barretts, the builders, 16 years ago. A replacement door was also fitted in the bay window, which is very secure. All the old windows were removed from site by the fitters. I have no hesitation in recommending Hertford Glass to anyone, especially our neighbours on this development in SG13. A job well done. Thank you. 👍👏👏

Hertford Glass completed our lovely conservatory on time, and far exceeded our expectations: was on budget and any minor issues were resolved without issue. Great company and staff would certainly have no hesitation in recommending them to anyone in the future.

Fantastic company and fantastic service
Customer Service
Hertford Glass replaced all our windows and doors over 11 years ago and they still look as good as new.Recently had a minor problem with the front door.Despite being outside the 10 year guarantee the company sent a surveyor round quickly who diagnosed the problem and proposed a cost effective solution.An appointment was made for a service engineer to call who was an absolute gem. He carried out the required work and left the job site spotless.

Replacement back door.
Customer Service
Hertford Glass installed our double-glazed windows and doors more than 30 years ago. The lock on the back door became defective and the door had to be replaced because fittings have changed during this time. We automatically go to Hertford Glass because we trust them to do a good job. They did the work without fuss, took away the old door and left everything tidy. We can't comment on value for money because we didn't approach any others trader. We recommend them without hesitation.
