Windows & Doors (uPVC & Metal)- 1 Apr 2023
Shard renovations created a new opening for a window to our en-suite. Sean was timely, tidy, clean and really respectful of our property which was greatly appreciated & made post-job cleaning lightening quick, meaning we were able to use the room again immediately. Would recommend Shard & are already planning ahead to consult them for our next project.

Architecture- 27 Nov 2017
I contacted Marius because he had good reviews and wanted someone reliable and capable so design a single story extension with large external and internal bifold doors. I wasn’t disappointed - Marius has been excellent throughout the whole design process and produced drawings to a high standard which met our requirements. Marius was an excellent communicator and always available to give advice when required. Further more, he went out of his way to contact local authorities regarding any questions I had at no extra cost to clarify any uncertainties. I would highly recommend his architectural services - he was good value and very professional.

Loft Conversion- 7 Aug 2023
I highly recommend Sohail Faisal of Samz Construction Services Ltd. We chose Sohail's company to complete our Hip to Gable with Rear Dormer Loft Conversion in Guildford and we are delighted with the work. The job was completed to a high standard, within the expected timescale and on budget. Sohail's communication throughout is excellent, taking time to explain what work will be completed on which days, what is involved and how many people will be attending on which days to complete the work. Sohail also let me know exactly when deliveries of materials were arriving and when the skips would be collected etc. Sohail's team of builders are all very friendly, polite, and respectful and do a great job of cleaning up after themselves at the end of each day. In terms of price and payment schedule, this was fair and efficient. Sohail has a payment schedule that works really well - invoicing for staggered payments at certain points, i.e. on delivery of materials, then when the building inspector signs off the first job etc. this makes you feel at ease with the job and confident that everything is always on track. All around I am really happy with the project and have no doubts about recommending Sohail to family and friends - I have already asked Sohail to quote on my next project.

Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

Loft Conversion- 23 Apr 2019
A very positive experience. We are not going to say everything was plain sailing. We got there in the end. Arick & Greg, the joiners were especially brilliant. Office communication could be improved at times and the office could be more pro-active. All of the others Duanne, Wesley and Rocky were great. There are a few things ourselves we have to do but now have a extra room in which to live and work. The guys put in long hours and put up with interruptions from our three dogs. Arick & Greg work incredibly hard and put in long hours ; much more then perhaps anyone else we have seen. It is always difficult dealing with things at a distance and we appreciate the office sorting things out when minor issues have arisen (we know they have changed some of their procedures because of us!). Overall it has been a very positive experience. Just glad that soon things will be completely finished and our new floor will no longer be like a building site. We believe we have added value to our house with the help of econoloft and our looking forward to moving in soon.

Questions to ask local loft conversion companies in Ongar

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 Ongar?

A local loft conversion company in Ongar 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 Ongar 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 Ongar 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 Ongar

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 Ongar before agreeing to start the work.

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

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