Loft Conversion- 11 Jun 2026
We recently completed a loft conversion with Dean and his team at Blakeon, and I couldn't be happier with the result. The workmanship has been excellent throughout, and the new loft space has completely transformed the house while feeling fully integrated with the rest of the property. What really stood out was the communication, reliability and flexibility. As the project progressed, I refined several design decisions before they were finalised, and Dean was always patient, accommodating and willing to discuss options. The project included a number of additional complexities, all of which were handled professionally and pragmatically. I also remained living in the house throughout the build, and the team were consistently respectful, considerate and easy to work with. I would have no hesitation in recommending Dean and his team and am already discussing future projects with him.

Loft Conversion- 23 Jan 2019
Dave originally came to give me a price on a loft conversion, I had just moved into the house and needed a lot of renovation done. I asked Dave to quote for knocking out a utility room and converting it in to a small room with patio doors, what I like to call my 'little conservatory.' area now. I then decided that I wanted to open up the kitchen area into the living room and move my kitchen into the large living room space, this meant knocking down walls and moving existing utilities. This was on going at the same time, I had asked Dave if he could lay a new patio for me and build a pergola. Dave and the team were really helpful in making my vision possible for my new home, nothing is to much trouble. On the big jobs, Dave and the team, worked consistently same time everyday, Monday to Friday. Dave really does have a good eye for creating spaces that I needed and creating solutions. My neighbours liked Dave's work so much they had him for their kitchen renovation too! when the work was complete, I had an off the street offer to by my house, which I declined. Dave came back to complete my bathroom, Dave and the team are hardworking, reliable and reasonably priced, given that so many people are charging a fortune just to knock a wall down these days, his quotes are all laid out in advance with detail of plans and he stays on site until the job was completed. I would happily recommend BGL. Thanks Guys fantastic job.

Plastering- 4 Nov 2024
LMG have just completed a full silicone render of the back of our house, over 3 floors. Really pleased with the work, and the general standard of updates and quality throughout. To find a company so reliable, with such great work is really hard, and wouldn’t hesitate to use them again. Chose SeaMist colour for the Johnson’s render, and it looks amazing. Also very pleased at the scaffolding provided, and then very swiftly removed.

Damp Proofing- 27 Nov 2025
I originally booked Darran for a damp problem because of roof leak, but he quickly discovered the real issue was a badly done roof repair from a previous roofer. Instead of doing the bare minimum, he took the time to fully inspect the entire roof, identify every concern, and explain exactly what needed to be done. He fixed all the leaks, resolved the damp, and made sure the whole roof was properly sealed and secure. What truly stood out was his honesty and fairness, another roofer quoted me thousands, and one even refused to touch the job unless I replaced the entire roof. Darran’s price was incredibly reasonable, and the quality of his work far exceeded my expectations. He is extremely knowledgeable, friendly, and reliable, and he even handled a few last-minute requests without any hesitation. He finished on time, kept everything tidy, and showed genuine pride in his work. Darran is a true all-rounder, and I honestly cannot recommend him enough for any home repair or renovation.

Questions to ask local loft conversion companies in Treorchy

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 Treorchy?

A local loft conversion company in Treorchy 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 Treorchy 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 Treorchy 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 Treorchy

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 Treorchy before agreeing to start the work.

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

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