⭐⭐⭐⭐⭐ Excellent Service and Quality Sash Window Installation by Optima Builders We had a great experience with Optima Builders for our sash window installation at Hampstead Garden Suburb. From start to finish, the team demonstrated a high level of professionalism, excellent workmanship, and a strong commitment to quality. Their work ethic was... Read more impressive, with the team being punctual, organised, hardworking, and attentive to detail throughout the project. They took great care to ensure the installation was completed to a high standard, with a neat finish that complements the character and appearance of the property. The quality of the sash windows is excellent, both in terms of appearance and performance. The installation feels solid and well-finished, and the windows operate smoothly. The attention to detail and care taken during the work really made a difference to the overall result. Communication was professional, and the team approached the job with care and respect for the property. It was clear that they take pride in their work and aim to deliver a quality product rather than simply complete the job. I would happily recommend Optima Builders to anyone looking for professional sash window installation, quality workmanship, and a reliable team. A very positive experience and a great result at Hampstead Garden Suburb!

October 22, 2026Daniel was a pleasure to work with, offering advice and guidance when asked and giving me confidence that what I wanted to achieve was never a problem. Looking forward to working with him on the next project.

August 30, 2026We hired Daniel to paint the interior of our house, and the results are amazing. The work is neat and the paint lines are sharp. They turned up on time everyday and kept the work space neat and tidy. The price was fair and the job finished on time. Daniel... Read more has also done work for other family members and friends who were equally as impressed with the work done and the standard the work was carried out too. If you want a reliable decorator who delivers to a high quality finish and result, I would highly recommend Daniel.

Builders with a dream Daniel and the Optima Builders team did a major renovation for our new home, a very old Edwardian property. A scope including structural changes, plumbing, electricals, an expanded open kitchen and three new bathrooms, and many many overall cosmetic changes. Renovating a home is difficult business. Once you... Read more start the project and open up the walls, you will constantly run into hidden problems and new constraints, and the scope of the work might increase. After all, you can only get certain things done while they stay open, and you know you never want to open them again. That is why it is extremely important who your builder is. You want a person with integrity. You want a person who really knows what they are doing. You don't want to have to question every step of that constant stream of very difficult decision making, or live in the fear that the quality of your house may be compromised without your knowing. When we started this project, Daniel told me it would be as if he is working on his own house, and he would take care of everything. And this he did. We did discover many previously unknown problems along the way, and sometimes had tough conversations on how to solve them. But never was there any discussion which was in bad faith, or any problem Daniel couldn't solve. He has 25 years of experience in the field. We must also say we were clients with many specific and peculiar requirements, both in terms of required speed as well as aesthetics. Optima Builders finished this complicated project in a mere 3 months, and faithfully implemented many of our design requirements that I know most other builders wouldn't even consider. He provided adequate expert consultation so that we, in our ignorance, didn't try to do something too impractical. Last but not least, my comments apply to not only Daniel, but the entire team. They were some of the sweetest and kindest people that I have ever met, and they worked with their sincere hearts. I am truly grateful that I had the good fortune of having this team work on my house, and would see any of them again with the gladdest of hearts.

June 21, 2026Daniel came to help us progress with the renovation of one of our bedroom. He gave a good push in our project (install new door frame, insulate external wall, fit plasterboard to walls & ceiling, skimming, change floor deck, and a bit of electricity). We have been happy with the... Read more work delivered. Daniel was available quite quickly once we agreed on a price. His quote are detailed with a breakdown too. Thank you.

March 8, 2026Review on: Daniel Wisniewski – Optima Builders Ltd Daniel laid new flooring in two rooms for me and I couldn’t be happier with the result. He and his colleague were extremely tidy, efficient, and completed the work to a very high standard with clear attention to detail throughout. Daniel was a pleasure... Read more to deal with from start to finish – always accessible, communicative, and helpful. He even took the excess flooring back to the shop for me, which was much appreciated. I will certainly be looking to use Daniel again for future projects and would highly recommend him to anyone looking for quality workmanship and a reliable tradesperson.

August 19, 2025Daniel fitted a new kitchen for us. He was very diligent, and worked hard to ensure the job was completed to a high standard. Daniel's team also re-turfed our garden and fitted a new fence - his team were friendly and hard working. And after several years, our kitchen... Read more still looks great and works perfectly, and Daniel is always on hand to help if needed - for example, Daniel recently fitted a replacement integrated dishwasher including plumbing, positioning, and alignment of the front panel. We would certainly recommend Optima Builders.
