Highly recommended

Ventrolla recently carried out extensive work on the front of our house, including a new replacement window, installation of double glazed sashes and casements, and refurb and repairs to our existing frames. In line with what other reviews have said here, the service we received was brilliant from start to finish, and we couldn't be happier with the results. The care and professionalism shown by our fitters (Andy, Lewis & Miles) was fantastic, and a big thank you to Catherine and Lee for going above and beyond with the aftercare.

I am bitterly disappointed with the draught proofing system Ventrolla installed 11 years ago. I know I'm outside the warranty period of 10 years now but I have only just taken back the flats after tenants left. Ventrolla have just visited and told me I have to repeat all the same work they did 12 years ago.

As it was a very expensive before I was hoping it would last longer than 12 years. Another expert tells me the sashes have been cut back too much, possibly to allow the sash to be manoeuvred for painting. The top sashes all move from side to side by maybe 5mm each way. I thought the solution was suppose to correct this movement. The windows don't keep the draught out.
I have now had a large quote to repeat the work all over again and the technician wont visit to assess the work until I pay a deposit. To be honest I don't want them replacing the system they installed.

Excellent restoration on Victorian property

We used Ventrolla to restore a large number of sash windows throughout our Victorian home. Some of the windows were in poor shape, they were very draughty and all needed some attention. I had limited expectations of what could be acheieved with the state they were in, but am absolutely delighted with the results. The excellent draughtproofing means the curtains no longer billow in the wind, and the fantastic restoration means all the windows can now be safely opened, closed and secured. It makes a huge difference to the property.
From the first visit by Russell to quote the work, and the technical survey from Jac, the guys at Ventrolla were thorough, had great knowledge and the sort of positive, problem solving attitude needed for working on older buildings. I felt confident in their expertise. When Andy, Scott and Paul arrived to do the installation they were tidy, considerate of the property, and showed great craftsmanship. Work overran by a few days due to scale of the job, but I was kept well informed throughout. I highly recommend Ventrolla for any heritage window projects.

A pleasure to deal with and a professional job

Everything was easy and clear from start to finish - prompt communications, understanding of our funding and LBC needs, and detailed information. Hayley and Lorna were great communicators, and Alan and Lindsay did a great job. Would definitely recommend, and we will likely use again for other windows that will need some repairs in the near future. In a world of being ghosted by roofers, talked down to by builders and having frankly bizarre conversations about the nature of reality with council planners, it has been a simple pleasure to deal with this company.

Bathroom window refurb on a listed building

As we live in a Grade2 listed building, I researched some companies specialising in refurbishment of Georgian sash windows as our bathroom window was in a poor state, draughty & the top sash wouldn't open. From quotation by Steve to installation, our window refurb was the most stress free experience. Dates given were all adhered to, albeit the job took a little longer than anticipated but that was down to the weather & nothing else and we were kept informed by Catherine (Project Manager) of the delay and both Dean (who refurbished the sash window) & Alan (who painted and finished the window once refurbished) were both extremely professional in their approach and workmanship. All mess was tidied up by both and probably left cleaner than when they arrived!! The sash window now works perfectly and looks great. I would definitely recommend Ventrolla for both their customer service & workmanship and as we have a few windows that need a bit of TLC, we will be using them again.

I had three Georgian windows restored and one made to match from scratch , the service for the restored windows and the fit of the new one was impeccable bar one issue , in order to fit the new window a brand new sink had evidently been stood on - there was a boot imprint mark in the stainless steel . A tarpaulin had covered the work top when the work men were there . I sent an email and photo the very same day alluding to the issue however my concern was dismissed and the damage was denied. It will probably only cost £ 50 to replace and my works cost in the region of £ 15,000 so I did expect they would at least call me or visit to see the issue .

Window Refit

From initial quote, to technical survey to fitting the service was considerate, friendly and efficient. Dave and James went the extra mile with a complicated window, taking out original panes and successfully reusing those where possible.

Window Replacement

We had 5 windows replaced and could not be happier with the job. From the estimate by Mark, to measurements by Davie, to office support from Hayley and Diane, to installation by Alan and Kevin everything went like clockwork. Communication throughout was excellent and the windows look great. A pleasure to do business with such a professional team.

I have used Ventrolla before with excellent results. While the quality of the windows and the work of the fitters is still great, the manufacturing process took over 5 months and during this time communication was poor.

Ventrolla are excellent in every way

Ventrolla are excellent in every way! From start to finish everyone involved has been efficient, very helpful & professional. We had Ventrolla windows installed in a previous house in Edinburgh too. Hayley & Diane in the Lockerbie office are wonderful & the fabulous teams we had working at our home were John & Paul recently (& previously it was Alan & Kevin). The windows are beautifully crafted & look perfect in our Listed property. Thank you to all at Ventrolla. We highly recommend this company.

Scottish team

Hello. We are currently in the process of having our new windows installed by Paul, Steve and Stuart from your Scottish branch. So far everything has far exceeded our expectations. The windows are beautiful and Paul and the team are an absolute credit to Ventrolla. Polite, helpful and very skilled at what they do. They have been working so hard in what can only be described as torrential weather without complaint. We couldn't be happier.
They are back next week to complete the installation of the new frames and to refurbish the rest. I am so looking forward to seeing the completed job.
I won't hesitate to recommend Ventrolla in the future.
