Petru fitted a new shower tray. It was a complicated job due to the location of the piping. Petru was very meticulous and ensured he completed the job correctly and to a high standard.

Extensions- 3 Jan 2025
Alexandr was a pleasure to deal with, frequently visiting the site to discuss variations with us and keeping us updated with progress. Ours was a complex project, very different to a standard rear extension, and there were variations and delays, but they were dealt with professionally and we are delighted with the final result. We would use MTB again and would recommend them to anybody.

Latest review:
I met Charlie and his team from CM Builders Ltd when they were completing a loft extension and ground floor extension for one of my neighbours. Quotation and budget I was given an estimate subject to drawings as I was on a strict budget that I had to keep to for the build. Charlie was able to help me keep to the budget, both at the final agreed plan and during the build. The project was complex in that whilst it was a loft extension, all of the house was rebuilt. The only thing kept was the external walls and first floor rafters. Whilst the footprint of the first floor was not being changed I wanted to bring it up to current building standards with extra insulation. All of the plumbing and electrics were also replaced including a new boiler. The overall build has come in on budget, save for agreed enhancements that I did not think of at the planning stage and or building regulations such as double ceiling fire plaster boards. There were also items such as the original stairs that I wanted to keep, but Charlie was able to increase the height space in the kitchen making the worktop much more usable for tall people for a larger part of the kitchen. These were suggested to me as potential options as part of the build. Stage payments The stage payments have all been sensible throughout the build and linked to the ongoing work schedule. I have not therefore had any concerns in this regard. Quality of work This was a very complicated build as unlike the ground floor the first and new second floor are “L” shaped. The new 2nd floor included an en-suite and 2 bedrooms. Overall the house has been increased from 2 bedrooms 1 bathroom, to four doubles and 2 bathrooms. The quality of work is excellent and Charlie project manages his team to ensure that they all deliver to a high standard- if it is not done correctlt they do it again, with Charlie spotting any issues. Timeline of build This has generally gone to plan very well. As with any build you have to be realistic as things will happen outside of anyone’s control. When issues have arisen Charlie manages them to a conclusion. Also be realistic if you are having to manage to a tight budget. I had to plan for various stage receipts of cash before I could order the kitchen and bathroom items - make sure you understand how this impacts the build and availability of the work force, recognising that CM Builders have to book kitchen fitters and plumbers. CM Builders are also very helpful in that they have sorted out issues with the brick work of my freestanding garage (nothing to do with the build) and also a neighbour’s wall that could have been dangerous to the public, should it have failed. Conclusion The whole family are very pleased with the outcome and we now have the equivalent of a brand new house that has been built to a very high standard. This has definitely been worth doing both from a valuation perspective and quality of life perspective. I would not hesitate to instruct Charlie and his team again.

Tiling- 24 May 2026
I cannot recommend John from Pacho Create Ltd highly enough. I'm a very particular client with high standards, I was impressed by his care, patience, and professionalism throughout. He clearly takes pride in delivering quality work and paid close attention to every detail. Living in a small flat, I was concerned about dust, but John proactively created a solution to minimise disruption, which I really appreciated. He also gave excellent advice on budget-friendly waterproofing products. We had a challenge with large-format tiles, but John worked closely with me to plan the layout, ensuring a natural, balanced finish. The workmanship is outstanding – minimal wastage, precise alignment, and superb attention to detail. I wouldn’t hesitate to use John again, in fact, I’m already planning to have him back to tile around my bath in the near future. I highly recommend him to anyone looking for a skilled, reliable professional.

Restoration & Refurbishment- 27 Mar 2022
Ricky Reid I was looking for a company who could help me with a light refurbishment (kitchen, bathroom and full decoration) of a one bedroom flat in south west London to be ready for rental within 15 days. I posted my ad request on mybuilder.com and a few companies contacted me. Ricky Reid, was the third one I met and eventually the one I chose. Why? R. was straight forward, no gimmicks and did his best to understand what my needs were from day one. Especially when my vision at the start wasn’t that clear. Him and his team delivered within the time frame agreed as well as within the quote given plus a few extras that hadn’t been considered at the start of the project. He was always available for questions or clarifications needed over the phone at any time! A rare quality in itself in the building world. If there was anything that could be improved, this would be clarifying certain jobs that were on the quote (and I mean specifically what they exactly covered) from the start to avoid stingy or unexpected surprises cost wise. However this isn’t Ricky’s fault and I take my full responsibility as I should have done my homework before hand. Overall satisfied with the result and I would certainly contact Ricky and his team for my next future projects and so should you reading this review. Thank you Ricky and all the best in your company venture.

Bathroom Fitting- 13 Oct 2015
Reece and his father did a great job in our bathroom and he was a real pleasure to deal with . He went above and beyond the role as he had to order and collect a bath end panel as he suggested it would be a better match from the one I had selected . He was correct in this. He is he first builder I have ever known to suggest an improvement, source it and collect it as part of the job !! I would thoroughly recommend him. :)

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Emir did a good job. The company did a bathroom refurbishment after water leak, repaired the damaged ceiling downstairs and painted the room. Emir’s attention to detail is very good and he went the extra mile to do the job properly. I will recommend his services.

Questions to ask local loft conversion companies in Winchmore Hill

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Winchmore Hill?

A local loft conversion company in Winchmore Hill will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Winchmore Hill should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Winchmore Hill loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Winchmore Hill

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Winchmore Hill before agreeing to start the work.

Do I need planning permission for a loft conversion in Winchmore Hill?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Winchmore Hill loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Winchmore Hill loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
