Loft Conversion- 4 Apr 2018
We cannot praise Johnny and his team enough. They were simply fantastic throughout our project - they have done a beautiful loft conversion, and transformed the rest of the house.. installed two new bathrooms, opened up the downstairs and installed a new kitchen, installed new front and rear doors and bifolds, restored original fireplace, decorated. They are delightful guys to have around, Johny keeps a firm grip of the project and makes sure things don’t get delayed. They are proper craftsmen and real perfectionists. They work hard, they have an eye for detail, they are unfazed by problems, they kept to schedule - you couldn’t ask for more. Johny was around to give advice at any stage we needed, they left things clean and tidy and have a real pride in their work. We would highly recommend Johny to anyone - he’s a great, trustworthy, hardworking and genuine guy who does exactly what he says he will. This was our first major building project but we couldn’t have been in better hands.

Tiling- 21 Jun 2021
Great professional and reliable service from Easy Solution. Waqar called me ASAP and arranged to see my bathroom. He came within 1 hour to see the job and gave me an affordable and good quote. He was available to start work immediately. Waqar also suggested the colour of tiles that would suit the bathroom and made some very good recommendations on where i could purchase them at a decent price. My work was done to a high standards. Tiles are neatly put together with grout and they are looking amazing! I had some many relatives comment on them and i have recommended Waqar to them all as i was so satisfied with his service and professionalism in my property. I will be using him always in future. Thanks.

Loft Conversion- 23 Apr 2019
A very positive experience. We are not going to say everything was plain sailing. We got there in the end. Arick & Greg, the joiners were especially brilliant. Office communication could be improved at times and the office could be more pro-active. All of the others Duanne, Wesley and Rocky were great. There are a few things ourselves we have to do but now have a extra room in which to live and work. The guys put in long hours and put up with interruptions from our three dogs. Arick & Greg work incredibly hard and put in long hours ; much more then perhaps anyone else we have seen. It is always difficult dealing with things at a distance and we appreciate the office sorting things out when minor issues have arisen (we know they have changed some of their procedures because of us!). Overall it has been a very positive experience. Just glad that soon things will be completely finished and our new floor will no longer be like a building site. We believe we have added value to our house with the help of econoloft and our looking forward to moving in soon.

Loft Conversion Company in Longfield
When it comes to house refurbishments I know that nobody wants their home to go through all that struggle every month. Every one of us has had this bitter experience to pay the price for good quality and receive a low-quality service. Here is why I would love to offer you a complete package of quality services at your disposal and everything at a reasonable price backed by long years of experience and protected by £2M public liability insurance. Convenience and peace of mind ONE CLICK AWAY!

Questions to ask local loft conversion companies in Longfield

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 Longfield?

A local loft conversion company in Longfield 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 Longfield 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 Longfield 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 Longfield

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 Longfield before agreeing to start the work.

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

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