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.

We had a terrible experience with VRS Building (Rimantas). After months of negotiating our renovation project & a verbal agreement VRS pulled out at the 11th hour. Rimantas's at VRS took a bigger job and contacted us by email and said "It's nothing personal, It's just business.' They have no loyalty to their clients.

Bathroom Fitting- 27 Jul 2024
Greg recently completed a full bathroom renovation for us including replacement of all fixtures, new tiling, painting and finishing. We're very happy with the final result - Greg was punctual, diligent and had great communication throughout the project. On top of this, he's a lovely, pleasant guy. Will definitely hire Greg again for other jobs and recommend others to do the same.

Bricklaying- 12 Nov 2016
Dear Brian I have tried to contact you on several occasions to complete the job. I really do not wish to leave negative reviews all over the Internet. Will you get in touch? Just ignoring the situation will not go away as I am now in receipt of your insurance documents and want to resolve amicably. I put you on notice to get in touch within 7 days. If I do not hear back I'm afraid I will have to start the legal processes as you give me no other option. I hope to hear from you within the allotted timeframe and do hope we can avoid litigation in this circumstance. Thank you. Dawn

Extensions- 30 Aug 2018
my experience of working with these guys was very positive. i eventually got a new kitchen fitted by them rather than an extension as the extension was above my budget. Their pricing was competitive, although not the cheapest. i made a conscious decision to offer the project to sall construction because they were experienced, and they were detail orientated with my plan as well as the fact that their timeline matched my project timing. the kitchen fitting was done, in fact, slightly ahead of the two weeks that sunny had said it would take-which was very useful. we also went on a holiday and left the whole place to them, and everything worked out for us, so clearly very trustworthy. sunny and his brother were excellent tradesmen and came back twice later on once we notified them of some small issues. its now been 1 year since the installation of the kitchen, and fingers crossed, everything looks and works great. everyone is impressed with our kitchen which is also indicative of their very good work. I will happily hire them again if i have to do some work on extension or refurbishing.

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Calvin and Jimmy have been absolutely brilliant, and have been the best builders that I have employed. So much so, that I have subsequently asked them to do a whole shopping list of things, from fitting a kitchen to removing an old fireplace. They are always on time, very polite, kind and knowledgeable. Best of all, they get things done quickly without any fuss. Calvin has been invaluable in sourcing items from trade required for the latest project, and clearly talks through requirements of any project. I would very happily recommend them for the excellent value they offer and fantastic level of workmanship.

Ali was brilliant at fitting my tap - it was more complicated than we thought and he stayed longer to make sure it was done, and even came back the next day to fix something that had gone wrong. Mohammad was brilliant, helping me with every enquiry and always answering really quickly, and patiently - super helpful. Overall, excellent - really happy - would definitely hire again.

What to ask a New Cross extension builder before hiring?

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

An extension builder in New Cross 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 New Cross 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 New Cross?

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 New Cross 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 New Cross 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.
