Ventrolla Anmeldelser 

I would have given Ventrolla 5 stars when they first put the windows in but within roughly a year the mastic from the top of the window frame has fallen off. They say this is not part of their responsibility in their contract, but but given that i had no choice but to rely on them to put in the mastic, it seems poor service to put it in such that extra costs are incurred. it was already inconvenient as frames came with primer paint. Had i known how poor the after service is, I would have chosen another company as there was another local one which was not that much different on price

I’m really pleased with my new windows and the whole experience from start to finish. Catherine, the Project Coordinator, was friendly, helpful and kept everything well organised. A big thank you to the installers, Andy, Miles & Lewis, who were professional, polite and did a fantastic job. The windows look great, and I’d happily recommend the team!

Absolutely great company! Andy, Myles and Lewis spent 3 days changing our windows and was very professional and polite.

They all work hard through the very hot weather. We were also told it would take them 4 days but 2 extra guys, Andy and Derek, came all the way up from London (i'm Midlands based) to get the job finished sooner. The finished product looks amazing

Can't fault them at all and would recommend them to anyone!

Rob, James, Tyler and Scott were friendly, communicative and did an excellent job, leaving the flat in great condition. Highly recommended!

From 7th- 10th August 2026 Rob,James,Tyler, Scott are amazing contractors !!

This is the third time we have used Ventrolla to maintain our sash windows. As before, we were very pleased with the service from Ventrolla from the first contact through to the installation. The craftsmanship is excellent. The installers were very polite, friendly, efficient and professional in their workmanship. They worked with minimal intrusion into the household activities. The end result is excellent and the rooms were left clean and tidy.

We had Tyler, Scott, James and Rob here for the past two days redoing all our windows, and they were incredibly efficient, respectful and professional. House was left neat and tidy, work completed quickly and skilfully, and all were warm and friendly despite being here first thing in the morning! Would highly recommend Ventrolla 👍

Fantastic experience from Ventrolla.
The installation guys, Dave and James were super punctual every day, very polite, very tidy and all round awesome dudes! I cannot commend them highly enough.

I love my new windows, they open and close tightly with ease, absolutely beautiful and top notch quality, and I am now draft free and a very happy customer.

Very pleased with the service I received, from initial contact all the way through to completion of installation. Staff courteous and respectful. Quality of work excellent.

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.

The whole process of having one new window fitted and one sash repair has been well managed and efficient. Thank you to Rob, James, Scott and Tyler for their professional work at the house and for leaving everything so tidy. I highly recommend this company.

I have recently had more completed by Ventrolla at my property. Carl and Dean who completed the installation at my property arrived promptly, were polite and courteous, considerate to our needs and completed the work to a high standard. Really pleased.

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.

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.

Well planned and executed. The guys doing the work were on time, courteous and tidy. We've used them twice now and they've been really good. Windows are no longer draughty!

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.

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 .

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. The level of attention to detail was high, for a really pleasing findih

The Ventrolla team Miles and Andy came today to fit a huge bespoke picture window. They did a superb job. Arrived on time, were professional and careful and very polite.
