We have received fantastic after sales service from GoldBerg Engineering throughout the project and would not have had the results we have, without Zilvinas. Goldberg Engineering has provided brilliant guidance throughout, through rapid response emailing, regular Skype and several site visits.

Extensions- 8 Sep 2016
We hired Stone cbm to build our rear extension in Feb 2016 and the job finished on time in April. If there were a best builder award, the winner would be Jas. He is not your typical builder; his communication and execution skills are second to none. He listened to all our requirements like a friend and provide solutions like a pro. We are pleased with the finish. The project is just about on budget and on time, and could have been finished earlier if not for the other tradsman we called in to do other work causing delays. We had all sorts of problems with all the other tradesman and Jas was always there to give us a helping hand. In hindsight, we should have hired jas to do our other work as well as the extension to reduce all the stress. Project managing is much tougher then we thought especially when most of the tradesman out there simply do not care about their reputation at all (even the ones with many good reviews on mybuilder). Jas on the other hand is extremely organized and highly reliable. We would recommend Jas and his team wholeheartedly to anyone and looking forward to working with him again for our next project.

Roofing (Pitched)- 17 Sep 2018
The job I required was to have some tiles removed and felt pulled back to get to the ceiling void and also to do this around a Velux Window. Jamie kept in touch with my regarding the job and was available for work at short notice, it was clear he knew about the roof tiles I would need. Jamie was very knowledgeable and knew how to get round the Velux window. He turned up with his team and they were very quick with the work and enthusiastic. They completed the work quickly and he even went away and got some extra tiles to replace any already broken tiles and also placed extra felt on to the roof for me. He was very friendly and I would recommend and use again for any roofing work required. He was punctual and ensured that I was happy with the work before he left and showed me what he had done. He was happy for me to pay him afterwards when I had more time.

Restoration & Refurbishment- 9 Sep 2021
The original job for a bathroom renovation turned into a much bigger job. Raphael and his team ended up helping design and renovate the bathroom, bedroom, living room and hallway. The team helped us source all the materials including underfloor heating and an incredibly intricate mosaic tiled floor in the hallway. They provided practical advise about what was best for the space, what would work within our budget and what would be easy to live with. For example, the team installed underfloor heating in the living room using wood effect herringbone ceramic tiles which would help get the maximum efficiency out of the underfloor heating whilst giving us the wooden flooring look we desired. Raphael and the team were excellent throughout delivering high quality work and we were more than happy with the final results. I would highly recommend Raph and his team.

I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

You NEED Housi on your project, they took the stress out of our renovation!! We would highly recommend! We got in touch with Housi to help with ideas to renovate a new property I was buying. Holly from Housi helped us with architectural and industry advise throughout the process even before starting full design services which helped me understand my budget more and where items from the survey and my design ideas could overlap. As I was trying to limit costs, Housi helped develop a phased approach to the works as well as assessing options to have a self contained rental unit to bring in income to pay for the final works later. Overall, Holly helped us find minimal abortive works whilst trying to maximise value and functionality. As well as design strategy, she helped us submit a licence to alter application as we found out the house was under a covenant agreement, and managed the project through tender also - meeting with builders and getting quotes. Most importantly, she was able to advise us where builders may be overcharging so we could assess the right builders for us. Working with Housi really made a difference to our project by helping us understand the different stages of a renovation. Holly offered so much more advice and reassurance than any previous professionals we had worked with on our last house and even helped us source re-claimed steel as we wanted to be as circular as possible.

Questions to ask local loft conversion companies in West Ham

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 West Ham?

A local loft conversion company in West Ham 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 West Ham 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 West Ham 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 West Ham

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 West Ham before agreeing to start the work.

Do I need planning permission for a loft conversion in West Ham?

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