Loft Conversion- 17 Dec 2017
Zafer did a great job of boarding our loft and fitting insulation in the rafters. We are really happy with the result (and my husband is never easily pleased!) He was punctual, worked long hours and did a good job tidying up after. His quote was very reasonable too. He even sorted out our heating problem while waiting for something to dry! Really nice guy as well. One of the best tradesmen we’ve used whilst renovating our home. Wouldn’t hesitate to hire him again.

Carpentry- 16 Apr 2017
For a number of reasons, Reinaldo is without doubt the best tradesman I have come across, After having Cowboy Builders ruin my brand new doors. The quality of his work was faultless, he was prompt, always on time and very efficient, his work and work area was always left clean and tidy, and his communication skills, with regards to problem solving and making sure that the work he was carrying out was to my requirements, was excellent. I gave Reinaldo a number of jobs to do over a few separate visits and was not let down once. I cannot recommend Reinaldo highly enough and will be using him again for any future carpentry & joinery works. Reinaldo is not a carpenter however a magician as he can spell his Magic on any given work with a smile.Thanks again ,Reinaldo great work!

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.

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.

Samouil and his team at KnowHow Decorating completed a major project restoring our house. Work scope included sorting the tired and broken windows , guttering , fascia panels. Replacing rotten window ledges was done with superbly crafted new hard wood. No task was too difficult as the house was looking shabby. Full painting inside and outside was really well done. We feel like we have a "new" house and Samouil and team are a pleasure to deal with. They go beyond to satisfy you . I do not hesitate to recommend them strongly and will use again anytime .

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Loft Conversion- 26 Feb 2025
Very polite and considerate, asked if he should take his shoes off on arrival which was much appreciated. Very knowledgeable and I can tell he takes a lot of pride in his work and wants to do a proper job, that will last. For the amount of work the estimate seemed very reasonable. I cannot comment on the work because I have decided not to go ahead, only because a lot of work would be needed on the first floor, which I hadn't realised. Based on my experience I'd recommend.

Marcin was a pleasure to deal with! He is knowledgeable and professional - he came and explained clearly what needed to done, he emailed me materials' list required and suggested suppliers with product links and he was very helpful at agreeing between us who will be supplying what material. He came and did the job without disruption, in an efficient manner. While he was quick he was thorough to ensure the job is done to a correct standard. He is smart and finds solutions that work. I wish every tradesperson was like him!

Questions to ask local loft conversion companies in Blackfriars

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 Blackfriars?

A local loft conversion company in Blackfriars 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 Blackfriars 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 Blackfriars 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 Blackfriars

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 Blackfriars before agreeing to start the work.

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

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