Bricklaying- 16 Dec 2021
I'm very pleased with the repair that Jack carried out on my garden wall. Even though it was a small job he took the time to do it properly and ensured the bricks that had fallen down were put back straight. It started raining a little on the day causing the cement to run. Jack returned a couple of days later to tidy it up like he said he would. On inspecting the wall today I noticed that the cement on the bricks on the inside of the wall did not look as neat as how it looks on the outside of the wall. Maybe the rain caused the cement to run too much, I don't know. Overall I am pleased though and I've asked Jack to quote for another job.

Kitchen Fitting- 29 May 2024
Nesha was brilliant from start to finish. He was excellent at communicating before the job and was entirely professional and hard working throughout, not to mention his quote was very reasonable. He worked really hard to get the job done quickly and he did it to a fantastic standard. We are so pleased with the finished product and he was a pleasure to work with. We cannot recommend Nesha highly enough.

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.

Extensions- 13 Nov 2015
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.

What to ask a New Cross extension builder before hiring?

Before hiring an extension builder in New Cross or extension building company in New Cross, 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 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.
