Restoration & Refurbishment- 4 Jan 2026
At the outset, Harry and his partner are good people. However, the job was not completed to a professional standard. Grout has started coming off from between the tiles leaving gaps that water can pass through, the door hinge was not properly fitted leaving a door that will not close, the radiator pipe clips were not fitted, tile trims are not flush with rest of the wall, shelves were fitted on top of old broken wood. And the worst part is that Harry did not turn up even after confirming a date to come back and fix the missing parts. I paid him extra for all the additional jobs, even though certain items from the contract were not done ( for e.g. replacing the bathtub panel ). They have multiple jobs ongoing at the same time and struggles to stick to schedule. If you get them I would advise not paying everything upfront and making sure contract is signed only after it is made sure that they would stick to schedule. I struggled to get them to commit to a date and stick to it.

Loft Conversion- 15 Aug 2024
Vic’s quote was extremely competitive. He and his team were very punctual, clean and tidy. The speed they work is phenomenal so much so the job was finished ahead of schedule. I was kept informed at all times and no extra work was taken on without my consultation. The end result is beyond our expectations. I would highly recommend Vic and his team.

Carpentry- 18 Aug 2025
Dennis gave a good quote, answered any questions I had, was understanding when the door was delivered damaged and had to put the job back a week. He arrived on time, he was clean and tidy in his work and made easy work of fitting our wheelchair access bathroom door (3ft wide). We are very happy with the finished result and will definitely go back to him if we need a carpenter in the future.

Extensions- 22 May 2021
I was left in a mess by cowboy builders. I found Sukhvindsr Singh from mybuilders and then I had nothing to worry about. He completed the project with utmost responsibility from erecting heavy steals to all the way up to finish. I was amazed with the level of his skills and above all honesty. This was a massive 66sqm single storey extension and he put up structure, brickwork, fibreglass roof , underfloor heating , tiling,electric work . He even went beyond our agreement to do bits and pieces to make sure i donot get stressed out. I have given him another job in same property to do patio 88Sqm with porceline tiling. Feature wall prepared by him stood out . Highly recommended and i will be surprised if he does recieve similar feedback in his future jobs.

Loft Conversion Company in Blackwater
In every neighbourhood there is always “that builder”. The one people quietly recommend to each other. Not because of flashy adverts or clever slogans, but because they showed up when they said they would, treated people with respect, and did the job properly. That is the kind of builder we have always tried to be. We are a small, family run building business, and I work alongside my dad. Between us we have many years of experience, and we still believe in doing things the right way. We turn up when we say we will, we take pride in our work, and we treat every home with care and respect. I started working in building and home renovation, learning my trade the traditional way, on site and hands on, working closely with my dad and learning from his experience. Over the years we have completed home extensions, loft and garage conversions, kitchens, bathrooms, and full renovations. What has always mattered most to us is not just the work itself, but the people living in the homes. Whether it is a small bathroom update, a new kitchen, or a larger extension or conversion to make a home more comfortable and practical, we take the same care with every job. We treat each home as if it were our own, because reputation matters.

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!

Questions to ask local loft conversion companies in Blackwater

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 Blackwater?

A local loft conversion company in Blackwater 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 Blackwater 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 Blackwater 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 Blackwater

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 Blackwater before agreeing to start the work.

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

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