Carpentry- 10 Sep 2016
I'm just discovered that through some oversight I've neglected to leave feedback on this job - replacing an old garden pergola, quite a large one. Lucas and his colleagues did excellent work and we were very happy with everything. We would certainly hire him/them again - if he's not too booked up, that isc! Highly recommended. Christopher Sykes

Roofing (Pitched)- 14 Nov 2017
Marcin was a pleasure to deal with! He is knowledgeable and professional - he came and explained clearly what needed to done, he emailed me materials' list required and suggested suppliers with product links and he was very helpful at agreeing between us who will be supplying what material. He came and did the job without disruption, in an efficient manner. While he was quick he was thorough to ensure the job is done to a correct standard. He is smart and finds solutions that work. I wish every tradesperson was like him!

We selected Hoam Build following several quotes from local builders. Deciding factors were their quote was competitive, their general responsiveness and their flexibility.

Roofing (Flat)- 1 Sep 2026
I contacted Pete to investigate a leak in my flat roof. The source of the leak was extremely difficult to identify, as there were no obvious signs of where water was entering the property. Pete suggested carrying out a water test, which I agreed to. The test successfully identified a potential problem area, and Pete then proposed a suitable repair. He provided a detailed quote along with photographs showing the issue, which gave me confidence in the recommended work. Once we agreed to proceed, the repair was completed professionally and to a high standard. Pete left the area clean and tidy when the job was finished. After waiting through the long dry summer for some rain, I can now confirm that the leak has been fixed. Pete was professional throughout, communicated clearly, and kept me informed at every stage. I would not hesitate to recommend him to anyone needing roofing or building work.

This guy don’t know what he doing. Didn’t know the job and no proper knowledge about the work. When he couldn’t do it sold us to another crook.

Loft Conversion- 27 Sep 2020
I met Jay for the first time on mybuilder.com; my job, roof extension received a huge interest; Jay was one of the first that came to discuss and he had one of the best quotes; although we discovered in the last second that the structural calculations were different from what actually the structure is, he was not afraid to get involved, and we worked along the engineer all the way through; his attitude and his team attitude was professional from day 1 until the end; the team came every day at the same hour and they were working really hard; in fact after just 1 day, the old roof was off, new structure was on with a rain proof cover; this thing told me from day 1 how professional and hard working they are and confirmed me that he was the right choice; the extension was done in half time just as a confirmation of above; they accommodated all my requests (like fitting air con pipes); the end result was great, or even better than expected; I truly recommend him and would certainly work with him in future projects.

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.
