Carpentry- 8 Aug 2023
Chris was quick to respond to my post and attended only a couple of days later to quote. The quote was very reasonable and I chose him for the job, based on his competitive quote, his evidenced standard of work and general personality. Chris has kept true to his word throughout the works needed (new door frames, all skirting boards - porch and living room, new floor in porch and new front door). He has unbelievable pride in his own workmanship and is incredibly trustworthy & reliable. I live in a very old property, that doesn't have a straight wall/floor in it - Chris' knowledge shone through with dealing with what may seem small to those of us untrained - he used all his 'tricks' to ensure everything was fully secure and gap free, everywhere (including his personal pride). I was able to have very honest conversations throughout, regarding the work and also additional costs to the quote (n.b. this was not significantly more, but absolutely reasonable due to additional materials) and his expectations were never unrealistic or beyond my budget, nor the conversations difficult or confrontational. I genuinely can't praise or sing Chris enough. His quality of workmanship, personal pride and outstanding personable style is a breath of fresh air. My final comment would be is that he is to be fully trusted, both professionally & personally and he will deliver you an outstanding job, whilst keeping you informed throughout, in an honest and open style. I'll recommend 100%

I needed one wall of living room plaster called Craig and he made the whole process so easy, he came round to give me a quote. Compared other workmen and craig was very competitive, he made the whole process easy, I was going to decorate the room myself but Craig put me at so much ease, that I gave him the whole job of plastering and decorating the room. I was worried that I wouldnt get the room done by Christmas. He promised that he would get it done. He was very prompt and the job got completed in the promised time frame. And I was very happy with the result

I hired Forever Construction Ltd for the renovation of my house which included rebuilding the bathrooms and kitchen along with small wear and tear and changing the electrical wiring. The quality of work was excellent and everyone in the team paid great attention to detail making sure everything was completed to a high standard and on time. The work ethics of the entire team is commendable and I was given the best advice whenever required. My adhoc requests were also accommodated whilst making sure the timelines for the work are not missed. I found the pricing to be fair and competitive. There were no surprise charges which made the entire renovation experience very smooth. I would highly recommend Forever Construction Ltd. to anyone looking for a reliable and skilled team for any renovation/construction projects.

Conversions - General- 4 Mar 2021
I have worked with a few builders during my time renovating properties and I can genuinely say Pat and Ed are two of the most professional, knowledgeable, hardworking and honest tradesmen I have come across. They quoted me a competitive price for my phase 1 works which included labour, all materials, skip hire, structural engineer and building control costs. I asked them to manage all aspects of the phase 1 renovation as well as organise the structural engineer and to deal with building control. The work included taking everything downstairs back to brickwork and replastering with bonding coat and multifinish plaster, replacing/replastering ceilings, building new stud walls, resizing window openings, removing parts of a chimney breast and knocking through between living room and dining room. They carried out all the work quickly and professionally and always went the extra mile to help out where they could. I was extremely happy with their work and would highly recommend them to anyone.

My wife and I recently had a complete garden overhaul which involved leveling our garden, installing approximately 40 railway sleepers, laying a large Indian sandstone patio, and new lawn, all of which was completed in a little under two weeks. Nathan and Jimmy were a pleasure to have around, they were polite, professional, hard working , and always arrived on time. I would highly recommend NJC building services, their work is to an extremely high standard and they are only happy at the end of a project if the customer is happy. I will definitely recommend NJC Building Services to friends and family, and will also be using them next year when I intend to have a new driveway installed. Many thanks gents look forward to seeing you again in the future all the best.

What experience do you have with similar extensions in Chatham?

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 Chatham extension builder’s ability to deliver a result that meets your expectations.
