Extensions- 25 Aug 2020
I did my due diligence on Vullcan, but things went downhill. After a week i got a pre-tax invoice for £3000 for a more "complex" drainage system which was already completed, this was the start of them trying to get around contract items and look for every way possible to charge extra fees which i can’t go through in the word limit here. When that dint work they refused to do the work. e.g. they literally installed a tempered glass sheet, with liquid glue on my roof and stated to me that this was a "roof window". I had to show them buildings regulations that this was unacceptable and illegal especially when our contract said it has to be a VELUX ROOF WINDOW! Promised a 6-8 week completion, this is 9 months later. I had now paid about 90% of the original bill and 100% of additional costs. The final payment was due after completion and a 2 week snagging period. But the demand for payments started, with threats to sue. This was laughable as they hadn't completed the job. •The roof was leaking •Electrical issues with the fuse box and multiple light /electrical points •Outstanding items •The buildings controls company stated they would not be able to sign off on the building work because of outstanding issues, which I wouldn’t have even known as they lied stating they HAD the certificate. I agreed to send a FULL payment to an escrow company and pay HALF of the costs so they can complete and fix safety issues but they refused! Shameful experience.

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.

Handyman- 20 Aug 2026
Very pleased with the work done. Chris assembled our IKEA triple door wardrobe with no fuss at all. He turned up on time, got straight into it and worked steadily throughout. The wardrobe is solid, doors are aligned properly. All the packaging and bits were cleared away before he left, so nothing for us to tidy up. Would happily book him again and recommend him to others.

Questions to ask local loft conversion companies in Smithfield

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 Smithfield?

A local loft conversion company in Smithfield 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 Smithfield 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 Smithfield 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 Smithfield

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 Smithfield before agreeing to start the work.

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

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