Loft Conversion- 31 May 2022
I agreed a price and schedule of works with Muli (Flamur Marku). The day before, he changes the start time from 9am to noon. On the day, I call him at noon, to ask if he is still attending. To which he replies, "I was just about to call you, I'll be there in an hour". I say to him that it is not a good start to our business relationship. That he should at least have informed me that he would not be attending. He said, just forget it then, and put the phone down. I want to warn other customers of his potential short comings, and to have other potential builders on hand.

Joinery & Cabinet Making- 30 Jan 2015
Robert is dependable, helpful and generally good to have in the house and on the job. Just one caution, my job was replacing kitchen worktops and he's not a plumber so we had some snags with the sink. Even so. I am a getting a quote from him for another woodworking job.

Restoration & Refurbishment- 4 Jan 2026
At the outset, Harry and his partner are good people. However, the job was not completed to a professional standard. Grout has started coming off from between the tiles leaving gaps that water can pass through, the door hinge was not properly fitted leaving a door that will not close, the radiator pipe clips were not fitted, tile trims are not flush with rest of the wall, shelves were fitted on top of old broken wood. And the worst part is that Harry did not turn up even after confirming a date to come back and fix the missing parts. I paid him extra for all the additional jobs, even though certain items from the contract were not done ( for e.g. replacing the bathtub panel ). They have multiple jobs ongoing at the same time and struggles to stick to schedule. If you get them I would advise not paying everything upfront and making sure contract is signed only after it is made sure that they would stick to schedule. I struggled to get them to commit to a date and stick to it.

Loft Conversion Company in Walham Green
I have had the privilege of working on a 260-year-old Grade Listed building in Islington, London, under the close supervision of conservation inspectors. This project required a careful balance of tradition and innovation — I combined the use of modern machinery externally with traditional, delicate methods internally to ensure the building remained completely scratch-free. My experience has given me a deep respect for heritage projects as well as the skills to deliver high-quality results on modern refurbishments.

Questions to ask local loft conversion companies in Walham Green

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 Walham Green?

A local loft conversion company in Walham Green 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 Walham Green 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 Walham Green 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 Walham Green

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 Walham Green before agreeing to start the work.

Do I need planning permission for a loft conversion in Walham Green?

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