Monsta Windows

Ben replaced our cloudy bedroom window. Absolutely no mess. Ben did a quick and professional job, reasonably priced and the bonus is that he is a really nice guy.

Ben and his team replaced several broken and misty double glazed panes efficiently and quickly. During which they discovered and corrected the dodgy work undertaken by the previous kitchen window installer and then offered to check and, consequently repair, all the other windows in the kitchen. Then Ben discovered the seized bathroom window handle required new mechanism within the frame (he had a spare in the van), so he replaced that too. All the time friendly and all the time keeping us informed. Best of all, all the extras were done under the same (very reasonable) quote. Really, if you're lucky enough to find that Monsta Windows operate in your area, don't bother with anyone else...

Ben is very friendly and keen to help, he replaced three double-glazed units that had clouded over. He showed me where the moisture had entered through the seals and repaired these before inserting the new units. He also went round and checked other windows and sealed those if they showed signs of deterioration as well. I asked his advice about a conservatory door that wouldn't close properly and he adjusted the frame for me. I would most definitely recommend him to other people and will use him again if and when I have the need.

Ben did a good job replacing a blown double-glazing window panel, and he charged a reasonable price. He responded quickly to my request for a quote, and was courteous, punctual and efficient in doing the repair so I have no hesitation in recommending his work.

Ben installed some windows for me back in December after my garage was converted into a utility room. My experience with Ben and his company was very positive. Ben was quick to respond to my messages and did a great job of the installation. More generally, Ben and his staff have been very friendly and supportive to me throughout the process, and have always had very helpful advice. Thanks again Ben!

I cannot recommend Ben and his team highly enough and feel very lucky to have found them. I had a difficult-to-find leak between the edge of my window frame and the side of my dormer window. I contacted many companies, but all of them said all they could do was replace my windows - even though my actual windows were completely fine and the issue was around the very edge of one frame. I had seen Monsta's name come up in my searches but at that point they didn't have many reviews so I hadn't initially contacted them. However, I noticed they said they did repairs, and on further investigation I realised that they were quite a young, new company, hence fewer reviews. Company founder Ben responded quickly, came round, figured out the right approach, measured up for a couple more jobs I added on, sent a fair and reasonable quote via email and booked in the work as soon as he could, kindly prioritising the leaking window issue. He did a brilliant job and his team also did a fab job a few days later on some other pane and window replacements elsewhere in my flat. I can't praise Ben highly enough. He is amazing at his job, extremely conscientious, diligent, ethical, working sustainably by repairing not replacing unnecessarily, honest, helpful and went above and beyond to assist me several times, even though my jobs were small and not big earners for his company. I would say grab Monsta whilst you can, before there's a long waiting list, because they are a one in a million.

We were urgently looking for an accredited glazier in South London to carry out a leak repair on a double glazed fixed window which was part of a set which had been installed some years earlier on a 60s end of terrace house which we were about to sell. We shortlisted 3 contractors - only Ben from Monsta Windows was prepared to do a site visit and, subsequently, a detailed repair. One of the other contractors said we needed an entirely new window. Ben discussed with us in some detail what he proposed to so, agreeing with us to come over at 9.am on a Saturday. He removed the fixed window and explained why there was water ingress from the frame. He checked the surrounding frames of the other windows, cleaned out the old sealant & applied new, cleaned drainage holes & added new ones, capping all with appropriate covers to avoid debris blockages. He replaced the fixed window, this time with appropriate glazing packers keeping the glass off the bottom of the frame where it should have been installed originally, thereby allowing any water to escape via the drainage holes. He took videos of what he was doing, tidied up afterwards & supplied a written report for our solicitors. All this for a very reasonable price done with grace, charm and good humour. We happily recommend Monsta Windows to anyone with similar problems in South London. Great job, Ben. Many thanks. We are delighted with Ben's work,

We have had a brilliant experience with Ben and the team. They were friendly, informative and approachable throughout. The whole process moved quickly from the initial quote, to placing the order and booking the install date. The installation was managed brilliantly with the team being considerate of our young baby in the house. We are very happy with the window! We also asked Ben to check/ advise on the condition of some other windows in the property (we recently purchased the house) he did not sell us new windows and instead fixed one that was not closing properly. His approach is very much appreciated and refreshing, when compared to dealing with other window companies that are super salesy and pushy! We are planning to use Monsta again in the spring to install bifolds at the back of our property. Would absolutely recommend this company to all!

we have had problems with water getting in and had opinions such as needing new frames . Ben was able to pin down what the real problem was ie in the sealing surrounds and correct it . he really comes across as an authentic guy who knows his stuff , does great work and is on the look out to save you money when he can . really pleased to find him and totally agree with the other reviewers . Highly recommended

During a recent storm our skylight glass blew out. Ben came out to inspect the damage the same day I called and made the roof watertight while the glass was being ordered. He worked cleanly and went above and beyond, even putting a towel over the top of the ladder so the ladder wouldn’t scratch the wall - I’ve never seen a trader bother to do that! I thoroughly recommend calling Monsta Windows. Excellent value too.
