Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

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 hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.

Questions to ask local loft conversion companies in Woolwich

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 Woolwich?

A local loft conversion company in Woolwich 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 Woolwich 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 Woolwich 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 Woolwich

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 Woolwich before agreeing to start the work.

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

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