Restoration & Refurbishment- 8 May 2012
We hired Audrius initially as his quote was very competitive and I felt confident with his knowledge and practical approach to repair our roof, this was to remove all the slate tiles, lay new felt, new batons and replace with as many usable original tiles, this was organised and completed with as little disruption as possible to ourselves and we were highly pleased with the finished roof. We discussed further renovation works we wished Audrius to carry out so work continued with loft conversion, basement conversion, chimney brests removed, new boundary wall, replastered ceilings throughout, his team were polite and always cleared away when they left for the evening and they were always early in the morning. All problems were sorted quickly and the best solutions found always with costs kept to a minimum, we also changed things here and there and Audrius always had excellent ideas which would save costs and keep our budget in check. Audrius and his team are professionals and we have other work for them in the future and will not be using anyone else.

You NEED Housi on your project, they took the stress out of our renovation!! We would highly recommend! We got in touch with Housi to help with ideas to renovate a new property I was buying. Holly from Housi helped us with architectural and industry advise throughout the process even before starting full design services which helped me understand my budget more and where items from the survey and my design ideas could overlap. As I was trying to limit costs, Housi helped develop a phased approach to the works as well as assessing options to have a self contained rental unit to bring in income to pay for the final works later. Overall, Holly helped us find minimal abortive works whilst trying to maximise value and functionality. As well as design strategy, she helped us submit a licence to alter application as we found out the house was under a covenant agreement, and managed the project through tender also - meeting with builders and getting quotes. Most importantly, she was able to advise us where builders may be overcharging so we could assess the right builders for us. Working with Housi really made a difference to our project by helping us understand the different stages of a renovation. Holly offered so much more advice and reassurance than any previous professionals we had worked with on our last house and even helped us source re-claimed steel as we wanted to be as circular as possible.

We’ve had multiple jobs done by Silviya. The first was a small extension and downstairs and partial upstairs refurbishment with new kitchen and 2 bathrooms fitted. This large job was completed within 16 weeks and looks exactly as we hoped. Given the extent of works we moved out for the build. The second was the construction of an outbuilding and garden redesign (patio and astro fitted). Again the results are great. We lived in during this project and I worked from home without disturbance. The latest has been the re-fit of new windows, front door and fixing the front render. Again, the results are very professional and minimal disturbance while the work took place. Will definitely use him and his team again, should we need any more building work and recommend them to others

Roofing (Pitched)- 17 Sep 2018
The job I required was to have some tiles removed and felt pulled back to get to the ceiling void and also to do this around a Velux Window. Jamie kept in touch with my regarding the job and was available for work at short notice, it was clear he knew about the roof tiles I would need. Jamie was very knowledgeable and knew how to get round the Velux window. He turned up with his team and they were very quick with the work and enthusiastic. They completed the work quickly and he even went away and got some extra tiles to replace any already broken tiles and also placed extra felt on to the roof for me. He was very friendly and I would recommend and use again for any roofing work required. He was punctual and ensured that I was happy with the work before he left and showed me what he had done. He was happy for me to pay him afterwards when I had more time.

Hard Flooring- 31 May 2026
Michael and Taras were great to work with. They were very accommodating to our needs given that we were installing throughout the apartment which meant a lot of moving furniture and sequencing the work to suit our diaries. The final product is great and we are very pleased.

Questions to ask local loft conversion companies in Lower Sydenham

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 Lower Sydenham?

A local loft conversion company in Lower Sydenham 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 Lower Sydenham 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 Lower Sydenham 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 Lower Sydenham

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 Lower Sydenham before agreeing to start the work.

Do I need planning permission for a loft conversion in Lower Sydenham?

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