Roofing (Pitched)- 5 Apr 2024
I recently had the pleasure of working with the A&R company for roof repairs and transformation, and I must say, I couldn't be more impressed. Not only did they do an exceptional job with the repairs and transformation of my roof, but Amar and Jatinder went above and beyond by assisting with other minor fixes. Their friendly demeanor and professionalism made the entire process smooth and stress-free. I highly recommend A&R for their top-notch service and exemplary team members.

Loft Conversion- 22 Mar 2024
Glad we didn't hire him. After agreeing on a price for loft conversion and back extension, Mr Rattan kept increasing the price by referring to minor things. Like charging extra for plate that goes on steel. First day when he turned up, he demanded that owner should provide tea and snack for his labour every day. Also he was not ready to include the agreed price on the contract (as he was sub contracting the job to someone else). Glad we cancelled him and hired another builder in his place. I have evidence of all communication I had with him, incase anyone wants it. I would avoid him at all cost.

Loft Conversion- 23 Jun 2024
We recently just had a major house refurbishment (loft conversion, interior strip out, open plan kitchen, decking and redoing the plumbing and electrics etc). Jason was superb at project managing the whole thing and he was exactly what we were looking for us to be able to get the house renovated while we still worked or were away for travels. He truly supported us and gave his full attention to this project (As he usually works one project at a time) and was very responsive to things. What I also liked is that he was transparent with all payments and communicated any additional costs so there were no surprises. My only comment I would have is the finishing is not necessarily the best and this needed more checking from us as we found quite few things that were not done and had to communicate with him which he then tried to sort out. Even after moving in, he's still very easy to reach and will address any snagging issues that we've had. Great service and great communication overall!

Bathroom Fitting- 10 Jan 2025
I have no hesitation in recommending Shri Krishna builders - Gagan, and his team Nitin and Sonu for all building works. I initially requested a new downstairs toilet, but they utilised their expertise for other works - a new bathroom and electrical works throughout my house. I found their work to be of a high standard, and equally importantly their manner was trustworthy, obliging - no job was too small or too big, and they were very helpful with their guidance on materials and ideas. I am sure our paths will cross again, when I next require a builder.

Loft Conversion- 2 Mar 2021
Unfortunately I made a mistake in awarding this Job to Amrik and his team the work . Unfortunately I had to get the works completed by other tradespeople as he had left it unfinished and not as agreed before we started . Furthermore , upon closer inspection it transpired some of his works was not up to regulations so needed to be redone. I have had no end of hassle and headache to sort this all out so want to ensure no one else makes the same mistake . He is a complete cowboy who will cut corners to save a few quid whilst smiling and being very polite . Work is of a low standard, it’s rushed and hardly ever do they check to see if what they’ve completed actually works . Don’t make the same mistake I did - hire someone reputable with verifiable work history and company insurances in place

We had a full house renovation and loft conversion completed by Reform Build Constructions two years ago, and we’re still extremely happy with the results today. From the start, their team was professional, well-organised, and clear about costs and timelines. They guided us through every stage of the renovation, offering helpful suggestions while making sure our ideas and preferences were always respected. The quality of the workmanship has truly stood the test of time. Everything was finished to a high standard, and two years on, the loft conversion and renovated spaces still look fantastic and function perfectly. The loft has become one of the most used and loved areas of our home. Communication throughout the project was excellent. We were kept informed at every step, and the team was always approachable, punctual, and respectful of our home. They also made sure the site was kept tidy and safe, which made the process much less stressful. Completing such a major project on schedule with lasting quality shows their professionalism and experience. We would confidently recommend Reform Build Constructions to anyone planning a home renovation or loft conversion

Restoration & Refurbishment- 22 Nov 2023
I had an out door room in my garden put up by some cow boys which I was left with needing a multitude of problems fixing. Our budget was quite tight but Pano provided us with quotes for each stage of the job detailing what was included in each stage this was really helpful. Pano was great at discussing and suggesting best ways to find solutions understanding our budget we never felt pressured to spend more. We trusted his guidance in the best way to complete the work. Pano always turned up when he said he would and at the end of each day left areas clean and tidy. Now the job has been completed we have the out door room we wanted and are really happy with . I would absolutely recommend him to anybody looking for a builder and would contact him again for further work . Thanks again 😊

Questions to ask local loft conversion companies in Southall

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 Southall?

A local loft conversion company in Southall 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 Southall 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 Southall 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 Southall

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 Southall before agreeing to start the work.

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

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