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

Carpentry- 15 Aug 2025
I would 100% recommend John and his team. We have been really unlucky with 3 other builders taking off with our money and not completing the work. John is very professional, took on someone else’s mess and done a brilliant job. We wanted exposed oak rafter detail and the team done an excellent job. John is very good at problem solving on the spot when there are issues, he is very approachable and keeps you updated with the progress throughout the job. What he has been good at is also talking through different options with us before doing different sections of the work and he does not take short cuts. If you need excellent honest builders John is your guy! We will get the decorations done and post the end product.

Conversions - General- 5 May 2025
Zak and his cousin began working on our project on the 10th of March and delivered everything on time. From start to finish, they were consistent, meticulous, and completely committed to bringing my vision to life. They worked collaboratively with me throughout the process, always open to ideas and focused on achieving the best outcome. Together, they handled everything — brickwork, building, tiling, rendering, plumbing, and electrical — with a high level of skill and professionalism. The quality of their work speaks for itself, and I’ve already recommended them to others. We are truly grateful for all the hard work they put in and couldn’t be more pleased with the final result.

Loft Conversion- 6 Mar 2018
Loft conversion. We were delighted with Peter and his team. We were impressed with the hard work shown by all of the builders on site. We were particularly impressed by the speed(2 months) and quality of the work at a competitive price. There was surprisingly limited disruption to family life. Most access was from outside with toilet facilities also located outside. As with all big builds issues will occur. These issues were dealt with switly in a professional manner. We would highly recommend Peter and his team

Handyman- 25 Jun 2026
Do not hire this individual whatever you do. He is highly unprofessional and condescending when you try to ask him any questions, he clearly doesn’t know what he is doing and just wings it. Always makes out the fault lies with wall or the part but never his lack of skill/competence. He fitted the bracket wrong way round and when I told him this he denied it until he was forced to face facts. The tv is tilting forward and he told me that’s how it supposed to be when the diagram says otherwise and it is supposed to rest flat on the wall. I now have to pay a competent person to come and fix his mistakes! I would give him 0 stars if I could! Avoid like the plague!!!

Restoration & Refurbishment- 20 Jul 2015
We hired Zebra Property for a complete strip out and refurbishment of a GF flat. The JOB: The job included initial removal of existing bathroom, kitchen and flooring. The works itself were for a side return wrap around kitchen extension, basement refit, installation of new kitchen and bathroom, new windows (including velux) and bifold doors, tiling and complete decoration throughout. FEEDBACK: Zebra were a great company to work with on this job. Communication levels were clear. There were inevitable delays to the project but there was always a focus to get back on track and deliver as quickly as possible. The resulting finish is a high standard throughout the property, with any minor snags completed quickly. Thank you!

Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.

Restoration & Refurbishment- 19 Apr 2026
Didn’t return to finish the job, respond to calls or messages in response to finishing the job. Sadly wouldn’t hire Ovi & Mihai (O&C) again. Friendly & responsive initially. Worked well, on time, eager to please, did a good job - not perfect but adequate, average attention to detail but corrected when asked. We initially had a faux chimney put in, they touted for more work & provided alcove shelving/cabinet ideas which we subsequently hired them for. They worked intermittently (dad around for first half of job then left for Romania) as this was agreed as best for both parties. However they left the job incomplete once paid (were paid on time, each time, with no bargaining). Didn’t respond to texts or calls, leaving cabinet doors unfinished, large chips & cracks unfilled. Laminate was also poorly cut around hearth stone, left chimney cutout unfinished with no cement to the base. Lack of respect and wouldn’t hire again as cannot trust they won’t disappear. Note previous reviews.

Questions to ask local loft conversion companies in Catford

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 Catford?

A local loft conversion company in Catford 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 Catford 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 Catford 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 Catford

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 Catford before agreeing to start the work.

Do I need planning permission for a loft conversion in Catford?

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 Catford 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 Catford loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
