Extensions- 15 Dec 2021
Valdemar and his team of workers were outstanding. I have never known builders to be so thorough, honest and just generally nice people. They can be trusted and gave honest opinions. They were in tune with the building control requirements and worked very hard always arriving on time and working solidly throughout the day. They may be a bit pricey but you definitely got what you paid for - First class workmen ship.

Loft Conversion- 22 Aug 2025
I had Panesar Builders build a dormer extension garden room and a bedroom above the garage around two years ago. I deliberately waited before writing a review to be sure there were no hidden issues — and I can happily say everything has held up perfectly. Before choosing Panesar Builders, I researched and spoke with many builders. His quote came in at a fair, middle-ground price — not the cheapest, but not the most expensive either. I felt confident in my choice, and two years on I can say it was absolutely the right decision. The work was completed to a high standard, communication throughout the project was clear, and the whole process was smooth. Two years later, the extension is still solid, with no problems at all. It has completely transformed our home. I really appreciated the professionalism, reliability, and attention to detail shown. I would have no hesitation in recommending Panesar Builders to anyone looking for a trustworthy builder who delivers quality work that lasts.

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.

Garden Maintenance- 17 Sep 2017
I hired DS Developments to completely landscape my small front garden. This involved clearing and levelling the area; moving and re-securing a bike shed; laying a patio and lawn; and a number of finishing touches. The area went from somewhat of an embarrassing eye-sore to an area of pride. One that several neighbours have already made compliments about. David provided a professional service from start to finish. His quote was more than I expected, but his knowledge and vision gave me the confidence to select his services. He provided a selection of options and stuck to budget; adapted well to new ideas/suggestions; and informed in advance where the cost would be impacted. He and his team also were as tidy and considerate as possible and I highly recommend their services.

Bricklaying- 25 Aug 2024
AVOID. Ernie incorrectly installed my drains under my house which has caused awful smells and sewage to leak under my house causing long term damage to my foundations Three professional drainage company’s have put a camera to see a Dropped pipe from new to old house. They have identified a connection that was never appropriate. Unfortunately, Ernie after being given many opportunities does not accept any responsibility. He is not an expert at all trades so be careful. I’ve asked him to help put right by exposing the floor which has Underfloor Heating. This has now cost me tens of £000s. My fault for not using a professional team at the beginning of my project.

Gus and Frank were brilliant. Their attention to detail and care for our project was evident. There was already an issue with our floor which Gus and Frank rectified for us before doing the tiling. The final finish was immaculate. We liked their work so much that we also got them to fit our kitchen worktop. Good communication and clarity throughout the job. Would definitely recommend!

Extensions- 7 Feb 2020
I had installpro put an extension on my kitchen by knocking a lean-to and extending into that space, also completed insulation and roofing on the new extension and existing roof, this involved building new external walls, damp course membranes, plastering, new cast iron radiators were plumbed in, new electrical circuits and sockets, tiling, skirting, painting, new sash window fitted, new guttering and fascia and even a fitted kitchen bench was made from scaffold boards, which came out really nice. Marek was very professional and everything was done in a timely manner, no waiting around once things were agreed on. Always early every morning and working full days, even one of his team worked a Saturday to stay on the timeline. The quality of the work was very good, I was impressed with the roofing, proper insulation was used throughout, at the side of the roof behind the fascia too and new lead flashing was finished properly. The team that worked here were very clean, always using proper dust sheets and cleaning up at the end of each day. At the end of the job, final touch ups were made after consultation, to make sure I was happy with everything and then Marek saw that a proper cleanup happened and everything was completed on time and on budget as outlined at the beginning. I can recommend Installpro, and I will use them again for future work on my property.
