After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.

We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.

Bathroom Fitting- 26 Jan 2019
Jav and Joe are nice chaps, gave a very reasonable quote and started really quickly (the following day!). We ended up using someone else for the floor tiles after Christmas (we already know them) so these guys took out our old shower enclosure and fittings and fitted new ones including tiling inside the cubicle. There was a damp issue and a leak beforehand- both of which they repaired to a high standard or came up with solutions to so that the job could compete in time for Christmas. They explained all our options well. They went out to get extra materials without an extra charge and worked at a weekend to get it finished in time. Pleased with the finish and I hear metro tiles are particularly difficult to get spot on. I would have liked a more comprehensive quote beforehand but they provide me with this on request and the job finished on budget except for the work around the unexpected damp which was a small extra charge and we were told about this before we went ahead with the extra work. Good all rounders who can do a whole job like this, altho for anything particularly specialist (such as complex patterned or mosaic floor tiles) I chose to use someone who just does tiling and that id already used- although they do work with a specialist themselves for such jobs and his work examples looked high quality so no need to source anyone extra if you want them to manage the whole thing for you. Would use again.

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

Loft Conversion- 23 Nov 2021
We instructed Masterbuild & Maintenance to undertake a loft conversion and side extension to our bungalow in the spring of 2021. Dan and his team worked tirelessly to ensure that we were happy with every stage of the build and it was never too much for any of them to make modifications to get the desired result. They were hardworking, diligent and genuinely cared about their work which shows in the quality of their workmanship and the various trades employed. Dan’s team worked well together and were on-site every day for the 6 month build. We thoroughly enjoyed working with them on the project and can honestly say that we couldn’t have imagined any other builders doing the work. We are over the moon with the end result and receive so many wonderful comments from people about the job. We would absolutely recommend Dan and his team to undertake any building project and cannot commend their work highly enough.

Questions to ask local loft conversion companies in Erith

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 Erith?

A local loft conversion company in Erith 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 Erith 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 Erith 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 Erith

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 Erith before agreeing to start the work.

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

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