Extensions- 9 Jun 2016
Celli Property Care did a very good job. They undertook some structural work for us; knocking through a wall, dismantling and underpinning a chimney breast and installing beams to open up our downstairs living area. All the work was done professionally and signed off by building control. They installed 2 new bathrooms, a new kitchen and did all the plastering, tiling and painting and decorating. They also renovated our floorboards, which now look amazing. The communication was excellent throughout, with Celino the project manager always going the extra mile to keep us informed and discuss options and programme. The builders were also very considerate. We are very happy with the end product. I would recommend them to others. Thanks Celli Property!

Restoration & Refurbishment- 19 Apr 2026
Didn’t return to finish the job, respond to calls or messages in response to finishing the job. Sadly wouldn’t hire Ovi & Mihai (O&C) again. Friendly & responsive initially. Worked well, on time, eager to please, did a good job - not perfect but adequate, average attention to detail but corrected when asked. We initially had a faux chimney put in, they touted for more work & provided alcove shelving/cabinet ideas which we subsequently hired them for. They worked intermittently (dad around for first half of job then left for Romania) as this was agreed as best for both parties. However they left the job incomplete once paid (were paid on time, each time, with no bargaining). Didn’t respond to texts or calls, leaving cabinet doors unfinished, large chips & cracks unfilled. Laminate was also poorly cut around hearth stone, left chimney cutout unfinished with no cement to the base. Lack of respect and wouldn’t hire again as cannot trust they won’t disappear. Note previous reviews.

Extensions- 15 Oct 2023
Outstanding Porch Replacement Experience! I am writing to express my utmost satisfaction with a porch replacement carried out by Harpal and his team (Vinod and co). From start to finish, the entire process was seamless and incredibly professional. First and foremost, the craftsmanship displayed in the construction of my new porch is truly exceptional. The attention to detail and precision are evident in every aspect of the design. The porch not only looks stunning but also feels incredibly sturdy and well-built, a testament to the high-quality materials and expertise of your builders. Moreover, I want to commend you and your team for their exceptional customer service. They were always punctual, polite and attentive to my concerns. Any questions I had were answered promptly and the team went above and beyond to ensure that I was completely satisfied with the end result. The project was completed within a reasonable timeframe and the site left impeccably clean upon completion. I appreciate the professionalism and efficiency demonstrated by your team throughout the entire process. I would wholeheartedly recommend Harpal's (Pauls Building Services) services to anyone in need of a porch replacement. Thank you, Harpal for transforming my outdoor space into a beautiful and functional area that I can enjoy for years to come. Your dedication to excellence has made this renovation experience truly outstanding.

What to ask a Rotherhithe extension builder before hiring?

Before hiring an extension builder in Rotherhithe or extension building company in Rotherhithe, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Rotherhithe?

An extension builder in Rotherhithe should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Rotherhithe extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Rotherhithe?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Rotherhithe extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Rotherhithe extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
