Roofing (Flat)- 2 Aug 2023
Stay clear of this person as he is not experienced builder and do not fulfill his commitments after taking money. Don't hire this tradesman unless you want someone not to turn up on agreed date and time or you want to chase him again and again without him picking up your phone calls or answering them.. My garden shed was leaking from the side. Amarjeet recommended to put new flashing on the garden shed roof to fix it. However, after putting flashing, the garden shed continued to leak from the same area he had put the flashing. He said this time the cause of leak were the joints which he failed to look into earlier. So, he fixed that. After second fix, the shed again leaked, this time directly under the flashing he had put. When I asked him to fix it, he refused saying that the issue is with the joints and not the flashing. I told him that I had hired him to fix the water leak and not the flashing or joints. I even said that I will pay him if the issue is different. After ringing him several times and then agreeing a date and time with him, he didn't turn up. He is not a professional or experienced builder. Having now spoken to another builder, they suggested that the issue is that the water is somehow going under the flashing he had put. There is a bigger problem of the water standing on the roof which needs to be fixed first and which this builder failed to notice. Unfortunately, I will have to pay another builder to complete his work!

Bricklaying- 11 Mar 2023
The builder came to build a single skim brick wall to the side entrance of my house -: around 120 bricks. He agreed to £300 for labour including inserting a door. Upon arrival, of which he came on foot, he had no tools, no bucket, no drill, no ladder. He had to borrow all of my husbands equipment and sent my husband out for extra materials on two occassions. The lintel he asked us to order was the wrong size, we ordered one that was far too big and wasted more money due to him measuring up the job wrong - again a waste of money. Then, we had to drive him to toolstation to buy a brick cutting tool because of this using our own time and fuel. You would assume a brick layer would have tools if they are doing jobs privately - his colleagues excuse was we are just starting up our private buisness. He then started asking for more money and stormed off leaving all the rubbish behind even though we gave him the £300 as agreed prior to the job. The wall itself is okay but again at one point he refused to build up to the top because of a metal screw apparently impossible to remove, so yet again my husband had to assist with the job and removed the screw. Honestly more hassle than it was worth. Also the door was not fitted so now will need to pay someone else to do the job. I do feel bad for them that do not have any equipment but when you pay money for a job you do expect a certain level of service. I wish them good luck in the future and hope they take this advise on board.

Questions to ask local loft conversion companies in Carshalton

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 Carshalton?

A local loft conversion company in Carshalton 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 Carshalton 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 Carshalton 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 Carshalton

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 Carshalton before agreeing to start the work.

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

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