Latest review:
We initially hired Michael to convert a bathroom into an office. After meeting him and discussing our longer-term plans, we quickly felt confident moving forward with him on much wider renovation works across the property. Michael worked closely with us throughout the entire process—from early ideas and structural planning through to execution. He consistently provided insightful, practical advice that added real value. His ability to anticipate issues early not only prevented problems but also helped us save money by refining the plans to maximise our goals and avoid unnecessary costs. Michael’s broad knowledge and skill set were hugely beneficial on a project of this size and within a tight budget. He made the process far less stressful and, at times, genuinely enjoyable. He kept me informed and involved at every stage, which gave me a great deal of confidence in both the quality of the work and the decisions being made throughout. Michael helped us renovate every corner of our four-bedroom maisonette in West London—from bathrooms and structural opening-up works to a full kitchen renovation, hard landscaping, flooring, and carpentry. The list goes on. His wide skill set and depth of knowledge were truly impressive and exactly what we needed, particularly as we chose to stay closely involved in the renovation rather than hiring a larger construction and project management company. We genuinely don’t feel we could have made a better choice. It’s not always easy to find a builder who is reliable, honest, and trustworthy, so I feel very fortunate to have worked with Michael. I would recommend him without hesitation and will absolutely continue to work with him on future projects, big or small.

Extensions- 29 Nov 2023
We had the most fantastic experience with Sarunas. He was highly professional from start to finish and completed the work to the highest standard. We extended our project significantly once we realised how excellent he was and he has now renovated our whole home over an 18 month period. He was able to guide us through the process and help us make key decisions which made the experience smooth and efficient. He is extremely skilled in all aspects of building, has high attention to detail and is a pleasure to have in your home! I couldn't recommend him higher and look forward to having him back in future to convert our loft!

Extensions- 20 Aug 2016
Fantastic service, Lucas and Darota are an amazing professional team always reliable and our kitchen extension is to an exceptional standard. Darota offers an amazing interior design service. The builders have been punctual, worked really hard and when we have come home from work the house is always tidy so we don't even feel the house is being renovated. We offered LD Property services more work after our kitchen extension/complete refurbishment to include a complete renovation of all our home including garden and driveway. The project has been managed brilliantly as we work full time this has been really helpful.

Windows & Doors (uPVC & Metal)- 28 Jan 2026
Very unhappy with how things went with Angle Construction overall. Poor comms during the transaction was the first red flag - no communication for 2 days the moment money was sent, however afterwards received an apologetic call - parts ordered and arrived in due course. Andrei turned up, and got to work on removing the old gate, but then started shaving down the post without saying anything -we were told after that the posts were not level. Eventually he said the door would need to be cut, which we agreed to. The door and posts were both cut to fit, but massive gap left at the bottom, and only half of the door fittings and no handles were installed! In addition, where the door was cut and the wood shaved made, a lot of mess was left all over the garden furniture and patio floor. Shocked at the lack of care and professionalism. He was clearly agitated and in a rush to leave. We have a working back door, but it looks like a real botched job. Not happy, and I would not recommend.

Kitchen Fitting- 5 Nov 2020
An incredibly positive experience from start to finish. I found Robbie and team were hard workers, very likeable and provided brilliant results. Comms throughout were excellent. With Robbie happy to discuss the job over the phone beforehand and put our minds at ease. A big shout out to the team for undertaking this work during COVID. We understand the pressures this places on our tradespeople and we thank Robbie and his team for their diligence and commitment to wearing masks in our home and working safely. A brilliant experience.

Restoration & Refurbishment- 3 Jun 2021
Enrico pulled in a great team to refurbish my bathroom. It wasn't a straighforward suite swap out as I added a window, switched from an electric to plumbed shower, properly plumbed in the sink and changed the orientation of the shower and bath. Enrico took all of the stress out of ordering and receiving all the different elements, he added in some great suggestions of final touches and kept close to all aspects of the project until I was fully satisfied with clear timings and payment plan etc. on top. It's an old house and there were curve balls from time to time but Enrico and the team took them in their stride and made it a great experience. I'm totally thrilled with the end result.

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

Earlier this year, I was looking for a builder to erect a side extension and was given the details of Colin Richardson. He came highly recommended by various other people. He always arrived with a smile on his face and always at the time specified. The day to day work area was always cleaned at the end or the day, leaving it nice and tidy. I am very pleased with the work both Colin and Michael did and I would recommend them ti anyone looking for building work to be done.
