Loft Conversion- 9 Feb 2020
We hired Ivaro to refurb our existing loft - including knocking down a bathroom and taking out the ceiling to extend the space. Rajiv was excellent from the start, very professional, communicative and accommodating. His staff were clearly very experienced and they completed the job quickly without disappearing for a few days. Although they charged more than some of the others who quoted, they were worth every penny. We even asked them to take on a few additional tasks, which again they completed quickly and to a very high standard. We would definitely hire them again and thoroughly recommend them. Thanks guys!

The project lasted from July 2023 to Feb 2024 and comprised of: 1. Single story rear extension with new kitchen and underfloor heating 2. 75m2 patio 3. Internal reconfiguration including removal / installation of walls, new flooring, plumbing (including new boiler), new door frames, doors and skirting, redecoration, carpentry for cupboards 4. Ventilation of existing roof The team are both friendly and professional with Alin always on hand to manage any questions / situations as they arise. The work is clearly costed and every two weeks a valuation takes place to ensure transparency of work undertaken both in original scope and any extras. The quality of the build was excellent, something the building inspector commented on. Alin was recommended to me based on past work, and I in turn would highly recommend him.

Conversions - General- 22 Feb 2020
Quoted £500 to remove small kitchen wall (<1m wide), make adjacent wall good, and move light switch. Removed wall, moved switch, and kindly moved fridge. Said he'd return to make wall good. On two occasions I arranged to WFH and he failed to show up or let me know. On multiple occasions he said he might be able to do a day but then didn't confirm. He did come by when we weren't in one day to drop wood off to cover wall gaps. One day I arranged for our dog walker to be in at 1. She waited until 3. I messaged Daniel later to ask what happened. He apparently came at 1.20 and waited for 15 mins. I believe he turned up and our dog walker didn't hear door but it's unlikely he tried to knock multiple times over 15 mins, as she was listening for him. Agreed he would finish work in new year. In Jan again failed to confirm days/times on multiple occasions. Finally agreed noon on a Sat. Failed to show up/respond to messages. Eventually got through to him - said his phone was broken. No explanation re why he didn't show up. Agreed he'd come the next Sat but no show again. No response to message or to later one asking if he planned to finish the job. Received a missed call but nothing further. I've left it a month as hoped he would get in contact. It's clear he has run off with £500, leaving giant holes in wall. I work long hours and weekends are precious. I have no patience for someone who has no respect for my free time, or for fact it's not possible to WFH all the time.

Plumbing- 9 May 2025
I’m very disappointed with the service I received. I initially hired you to fix a leak, but the same issue reoccurred just a month later. When I contacted you, you said will go on a Monday and didnt turn up, when I sent you several messages after a week you said you were in the hospital, which I completely understood and respected. However, weeks later you promised to return on a Thursday to check the problem, and you never showed up or contacted me to explain. Since then, you’ve ignored my messages entirely. This lack of responsibility and communication is unacceptable, especially when dealing with ongoing issues in someone’s home.

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.
