Extensions- 21 Jan 2023
I’m a bit late adding this review but Vasile just reminded me. We are really happy with the home that Vasile built for us. It’s a Victorian terrace over 3 floors that needed a full renovation including electrical re-wiring, new plumbing etc plus a gf side and rear extension plus a loft conversion. Vasile and his team worked really hard to get us the finish we wanted. He always was on-hand to solve problems from building control to water pressure. He was always very friendly to work with and extremely respectful. We always got the impression that he wants to make his customers happy and takes pride in his work. Because of Covid and issues with materials and the labour market, our job took longer than expected but I think this was really outside of anyone’s control. We now have a really beautiful house that we love living in and it’s in no small part thanks to Vasile. I have recommended Vasile to friends already and have shown some of his potential customers round our house. They were always really impressed and inspired.

Loft Conversion- 7 Sep 2020
JMD demonstrated the upmost professionalism in delivering this one of a kind Architect designed roof and kitchen extension. They delivered on budget, communicating clearly any problems and agreed additional costs as the project went on. The project presented a very difficult logistical problem with limited access which JMD handled with great care and consideration in difficult circumstances. The whole team have remained positive, friendly and helpful throughout one of the most testing times in living memory. Covid extended the period of work beyond anyone's control, but JMD managed the situation dilligently and through sheer hard work reduced delays as best they could. We are absolutely delighted with the finished product which ended up better than we could have imagined when we started. It looks stunning. Well done to everyone who worked on it.

Carpentry- 22 Mar 2018
Ross and his team did a nice job. I was particularly impressed with the carpentry work, a good finish with a lot of attention to detail, the carpenter was very willing to discuss exactly what was required. Some of the masonry work did require additional correction and had to be pointed out to be fixed. But if I had any complaint it was with relation to some slow communications and removal of waste materials upon completion of the job but overall I would certainly recommend.

Questions to ask local loft conversion companies in Surrey

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 Surrey?

A local loft conversion company in Surrey 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 Surrey 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 Surrey 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 Surrey

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 Surrey before agreeing to start the work.

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

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