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!

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.

Conversions - General- 29 Sep 2022
The job - gutting our living room. Tearing down the ceiling, removing all old wallpaper and ripping up the floor in order to insulate and add lighting. While we were doing this, we decided to replace the main steel in the living room (which was oversize and impacted the floor height in the guest room) and do remedial works in the guest room. The steel replacement was not time budgeted, but Oli and Tony didn’t hesitate to quote,To make time for us and bring in the structural engineer. Probably added 3 weeks to their time on site. The trades they brought in (plumbing for heating, electrician for downlighters, structural engineer and plasterers) were all professional, did an excellent job and were all unfailingly polite. It was easy to build a good, positive relationship with them, to the point we felt comfortable giving them the keys to the house so they could work while we went away for two weeks. They sent photos of their progress and showed up and worked as if we were there. I was very impressed by the state of the house when we got back. They watered our plants (I didn’t ask) and they cleaned the hallway so that it was spotless. They did a good job for a fair price, and were always cheerful and open to conversation. They came back to do a few snagging items without being chased (this is a huge thing for me, after having chased many builders to finish bits and pieces). I would definitely use them again.

Questions to ask local loft conversion companies in Wallingford

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 Wallingford?

A local loft conversion company in Wallingford 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 Wallingford 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 Wallingford 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.
