Restoration & Refurbishment- 24 Apr 2019
I hired Dursun Altun and his team for a full refurb of 3 bed house. His business co-ordinator Ayse was helpful throughout the whole process and listened to the design requirements we had. Dursun provided full new plumbing and new boiler and all new electrical work. We had all our windows and doors replaced and are happy with the work done. His team fitted new bathroom, shower, toilet and also the kitchen. They also did some carpentry and provided shelves and doors for closets. His team decorated/painted and cleared up at the end of the job making sure it was all left clean and tidy. They did a good job and delivered on time! Dursun and Ayse made sure we were happy with the job and were lovely to work with. The job was done to a good standard and I would recommend them.

Joinery & Cabinet Making- 16 Dec 2022
I'm so happy with shelving that ozzy and his colleague made. Ozzy took the time to understand want I wanted (floating alcove shelving) provided a clear and comprehensive quote, and kept me updated on completion of the shelving in his workshop. On day of installation, the guys were lovely and friendly, they went the extra mile in dealing with floors and walls that aren't at all straight, and the finished result blew me away, it's transformed the space completely. Such a pleasure to deal with, would highly recommend and i would definitely use them again in the future.

Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

Questions to ask local loft conversion companies in Slough

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 Slough?

A local loft conversion company in Slough 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 Slough 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 Slough 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 Slough

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 Slough before agreeing to start the work.

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

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